    Denali, I am scratch building my 4 place. I have a little over 700 hours in so far. I have all ribs formed up and half primed with stiffener angles riveted on, aileron pushrods welded up, spars cut to length, bent, and lightening holes cut in them, spar splice plates and spacers cut to size and predrilled. I also have the aileron counterbalance tubes filled with lead and cut to length and the aileron nose skins are cut to size and bent. One flap is almost complete, I still need to make the hinge brackets and trailing edge. The other flap is sitting clecoed together waiting for the weather to straighten so I can paint and rivet it together...I also need to make the hinge brackets and trailing edge for this one. Both ailerons are framed up but I found a mistake (hinge pocket to narrow, I wouldn't have been able to insert the bolt on assembly) before I drilled the nose skin which will add about 20-25 hours to the build to fix. EVERYTHING takes longer than you think it should. When I set out on this journey I vowed to build the best airworthy aircraft I could...I have no intentions on building a show plane but I do the best work I can do.

    I expect to have at least 4000 hours in mine before I fly it. I am hoping to have it flying by the time I retire. I am that guy in the neighborhood who is always building or fixing something in his garage, most likely keeping people up at night when I loose track of time. For me, the journey is as meaningful as the destination which in this case a flying aircraft. Successful builders "get" to build an aircraft to fly later, many many unsuccessful builders "have" to build their aircraft. I arrived at Airventure 2011 ready to drop money on a RV-7 tail kit. After a week of attending forms, walking the aircraft parking areas, and actually sitting in some I realized that I was going to have to be brutally honest with myself and my intended mission. I went home and continued researching and being honest with myself and my situation and ended up ordering a set of 4 place prints. I have more time than money and there was no way I could come up with 40 grand for a kit and after looking through the print I realized that most individual parts were not all that difficult, there was just a lot of them.

    The bearhawk is one hell of an aircraft, both in construction and size. I am also helping a friend build a rans s-19 and another who is rebuilding a Zenith 750(?), anyway, those planes are junk compared to how the bearhawk is built. Now don't get me wrong, I am not totally cutting them down, but if you are looking for a plane to survive a crash or hand down to the next generation you are much better off with an aircraft built like a bearhawk. The Rans and Zenith planes are thin and "tinny" compared to bearhawks or RVs (-12 excluded). Keep in mind that the Rans and Zenith birds are "pop" rivet planes, there are very few if any driven rivets and most of them are not countersunk which saves a buttload of time. Rans, Zenith, and the RV-12 are good planes for their intended purpose and to the best of my knowlege are LSA planes. You cannot fairly compare a 4 place welded steel tube, fabric covered aluminum wing aircraft with driven rivets and a 2500 gross weight aircraft to an LSA legal pop rivet plane. I have seen the craftsmanship and completeness of the 4 place qb kit and the price seems fair for what you get. It appears to me that the Avipro group has completed about as much as they can and still be 51% legal. As for the "claimed" hours to build, take them as a grain of salt. If you are an experienced builder with the ideal setup, hit it hard everyday after work and on the weekends, have everything planned out and ready to go you might be able to reach the claimed build time. IF you stick to the plans, you will have a lot better chance of the aircraft flying in a reasonable amount of time. Custom modifications add a lot of time, more than you would think.

    I am not trying to be discouraging or cut other aircraft down, but simply trying to emphasize the scope of the project. Think of it as building a car from scratch, most wouldn't even attempt it which is why companies like Factory Five exist...to provide a means to build a car in their garage when the reality is that most are going to simply head down to their ford or chevy dealer and buy a car.

    If you decide that building is not for you, find a flying bearhawk or a maule. The maule is about as close to bearhawk performance as you will get in the certified world. Best of luck with which ever decision you make.

        For me I love the build process. I am not pressed to get it finished because I have another plane to fly. I always have to have something to work on. I have done extensive work on a few certified planes and now the bearhawk patrol. I travel a lot so my build gets interrupted a lot but it is always on my mind. While I am traveling g I am planning my next steps and planing I how I will do my the fabrication of the next pieces. So even if I do not physically do work, I do a little work on it every day. I also look at it as one step a time instead of the entire process.

          I have wanted to build an airplane since I was in Jr High, so this is just a continuation of a dream. Once I settled on a design, I went for it. The Bearhawk has lots of build options. Personally, I figured how many hours people averaged for their wings and fuselage, divided that into the cost of QB components and came up with an hourly amount for my labor. If I did the wings myself vs. Bearhawk Aircraft QB I would work for about $2/hr, so I bought the QB wings. Best decision I ever made. After all, I do want to fly eventually! The fuselage figured out to about $10/hr, but I really wanted to weld one up from scratch. First fuselage I ever did and it came out fine. Never welded before other than my MIG I have for the farm.

          At the risk of offending some, those that go to those "build" centers and taxi out with an airplane in two weeks are kidding themselves. You got a participation medal that you can fly with your checkbook. Building an airplane is work, but I really love the process. YMMV.

            I would like to add a little different perspective...

            First of all, I'm hoping that my QB is not a 2000-hour project. My prior build was a QB RV7. It took two years and right at 2,000 hours... pretty much what Van's claims is average. Bearhawk's estimate of 850-1200 hours was a factor in my decision to buy. Like the original poster, I too suffer from a lack of free time. However, if it takes longer than the 850-1200, so be it. I started my QB in January 2013 and my goal is OSH 2015.

            I'm pretty sure the build time varies greatly depending on prior building experience and just how much "experimenting" you want to do. I've seen the same long builds on RVs when folks tend to make extreme changes to the plans. That's not meant to be a criticism, just an observation. For some, that truly is the joy of building an experimental aircraft. I also think that the BH is not as easy to build as the RV for a first-time builder. If you ever looked at an RV build manual and drawings, it's pretty much "Attach Part A to Part B." I'll be the first to admit, it spoiled me. However, I think having built any aircraft is a huge advantage. Remember just trying to make sense of and decipher hardware parts numbers when you first started out? You will also find that once you have built you have a nice assortment of necessary tools... and even some spare parts... only requiring one order per day to Aircraft Spruce instead of two.<g>

            Finally, while I do enjoy the building - most of the time - I am anxious to fly. I was one of those who had to sell my prior plane to fund the BH. Being without an aircraft is tough. Fortunately, I do have access to a spam can I can borrow once in a while to get my fix. But besides the "joy of building," I would have to add to one of the prior poster's comments that there are many other reasons to build:

            First, you cannot buy a certified aircraft that will perform as well, whether you are interested in the speed, economy and nimbleness of an RV or the utility and shortfield capability of the BH. Anyone priced a Husky lately? Unless you're in the "top 1%" you will also probably have to settle for an airplane that is as old or older than you.

            Second, my cost of flying during the eight years I had my RV was also nil. Doing your own annuals versus hiring an IA (or going to an FBO, heaven forbid) for your annuals and maintenance makes flying and aircraft ownership very affordable.

            Finally, as the builder you are free to make almost any change you desire to your experimental aircraft.

            In summary, yes, for me the building is part of the picture. I live on an airpark and watching no less than five other aircraft under construction really gave me the bug again. But I'm equally enthused about flying that plane I built.

            Just my two cents.

                @ X'N

                You asked : " While its not the airplane a BH is have you looked at the Zenith CH 801 ?

                I actually have...a lot, but I don't want a nose dragger, the 801 cockpit is a lot smaller ( front to back, not transversely ), and the leading edge slats really do a number on the speed of the plane at V 75% even with its shorter 31' 4" wingspan. I have also heard that it oil cans a LOT. It's a fine plane, just not for me.

                I also like the Backcountry Super Cub " BOSS ", although build time is unknown, and it has a 40 foot foot wing and anterior slats, so I will be curious to find out what V75% is with a say 80-200HP engine. The BOSS has a big long wide wing with considerable parasitic drag. I know the BOSS will be able to go up and down like an elevator, but can it say break 110 MPH at V75% ?




                Another option is the Dream Aircraft Tundra, which is all CNC machined pieces and they claim it goes together like a giant erector set. Build time is unknown, but thy do offer a Quick Build Kit. It lacks a string builder's community like the BH, Zenith, or RANS.



                As I said earlier, I would enjoy building, but I might not ever find the time. Not being lazy...just realistic. So...maybe it is going to be Maule time. :-) who knows...

                  If you like spam-cans, you're forgetting the Murphy Super Rebel SR2500, but -- expect a larger, heavier plane, bring $$$,$$$, expect to spend similar build time, and again less performance than Bearhawk in several regards.

                Denali, I was thinking about your dilemma as I walked to work, reading Joe's post, the above sentence stood out for me.
                Even though flying is the goal for many people, including myself, the journey to get there is a heap of fun too.
                I got to enjoy spending 1700hrs building (with a lot of mods and more rework than many), it's a good thing. If I just wanted to finish, it could have been done faster, but you find yourself really enjoying the process.

                Here is a list of subtractions(from my actual build log) if you wanted to do it faster:
                25 hrs -- Custom air intake
                28.5 hrs -- Cowl flaps
                41 hrs -- Electric trim
                59.5 hrs -- Skylight
                20.5 hrs -- Observer doors
                20 hrs -- Realign stringers
                21.5 hrs -- Baggage tube
                100.5 hrs -- Unusual rework...
                ___________________
                315.5 hrs

                That is all additional build time, at a conservative estimate. So it's really more like a 1300-1400 hr build for a very very first time builder.

                  @ Battson

                  Thank you for your comments. I really appreciate the comments on the tinniness of some of the other designs. I was thinking the same thing. I have a pop riveter ( Nice BigDaddy Marstin Model 39010 ), but the solid flush does seem so more "substantial" plus the various styles. I just love this old old riveting video by the way:



                  Anyway, the challenge of buying an already assembled Bearhawk is that not many out there for sale, mainly "unfinished kits". Say one works 5 hours a week on a plane.In one year you are 260 hours into the project. Not much. You might be looking at 4 years to complete a Quick Build.

                  As far as improving the kits to reduce build time, that process does not necessarily require upping the % of the portion that is factory fabricated and assembled. Instead it could mean simplifying how a part is assembled, or making fabrication easier. I watched a 2009 assembly video that suggested bending certain pieces with a brake and using bandsaws to cut th window lexan.. I guess what I am appealing for is more of an IKEA mindset by Avipro for the quick build kit. So I guess what I a seeing currently is a minimum of say 750-800 hours for the very basic Quick Build Bearhawk,

                    If you can afford 1 hour per day after work, plus at least a half-day each the weekend - for building - you CAN have it done inside 2 years. The trick is having the kitset at home, so you can build after work.

                  I also considered a Maule, but bought a Bearhawk and am glad I did. I have now owned 2 pre-built experimental and can't imagine living with the limitations of a certified airplane. While it is true that there aren't many Bearhawks on the market, it should take considerably less time to find one than build one. .…mine is not for sale. ;-) -- Bearhawk

                    This may be a little off topic, but how many Bearhawks can one reasonably expect to see at OshKosh in July/August 2014 ? I'd like to look at the builds and ask the different owners about their experiences. Of course I expect AVIPRO and Bob Barrows to be there as well.

                      I was there near the end of the week and there was I'd say around 7BH, 1 patrol, 1 LSA.

                    Well, it happens. I bought out another Patrol builder last year who had lost interest. And there's at least one other in town that keeps trying to sell me his fuselage. For myself, I decided to scratch build while building my Challenger because I found I really enjoyed the fabrication type work. The actual measuring, cutting, fitting etc. Also, with an aircraft designed to be scratch built, I don't have to worry about the company disappearing and leaving me with a half built aircraft I can't finish. That said, I'm very glad that Avipro is offering Patrol parts and kits, so I have that option for anything I don't want to build myself.

                    As for the time. I think part of the reason it varies so much is just what time people log. For example, my actual build hours will probably be less than many people, because I only log time actually spent making parts that will go on the plane. I don't log time spent studying plans, making material lists, building jigs etc. And finish work can make a huge difference too. Fancy multi-color paint schemes and high class interiors add up to a lot of extra hours. For myself, I enjoy the building process as much or more than the flying, so I don't worry about the time. Working on the Patrol is almost therapeutic for me. I sleep better, and am in a better mood the next day if I spend a little time in the shop.

                    The other part of my story is that I have plans #P073. I purchased my plans in 2005 or 6, somewhere in there. But, life happens and I'm just now starting to work on it regularly. In the intervening time I've been taking classes to learn the skills I needed, studying the plans (I could almost build the wings from memory now), making material lists, gathering tools and all the other little things that are helpful now.

                    I guess to sum it up, If you want to build a plane, then by all means start building a plane. If your main interest is to go flying, then buy a plane and go fly it.

                      I fully agree with that. One could easily add or subtract hundreds of hours, depending on how you define "build time".

                    The way I understand it, the 51% rule only appiles to the E-AB definition. It must satisfy FAR 21.191g to obtain an experimental-ameteur built certificate. 100 people can work on the plane, as long as they collectively complete the major portion. It can get this airworthiness certificate even if no one gets the repairman certificate. Again, that's only my understanding.

                    Getting the repairman certificate is a separate application process. I'm not familiar with it, but here's what the FAA says: May I obtain a repairman certificate for my own amateur-built aircraft?
                    You may obtain a repairman certificate for your own amateur-built aircraft if you built the major portion of the aircraft. The only privilege this certificate gives you is contained in 14 CFR section 65.104, "Repairman Certificate - experimental aircraft builder - Eligibility, privileges and limitations", i.e., to do the annual condition inspection.
                    The privileges and limitations for repairmen are in 14 CFR section 65.103, "Repairman certificate: Privileges and limitations". To obtain a certificate, apply through your local FAA Flight Standards District Office.




                    I'm not planning on a minute less than 3000 hours actual time in the shop wearing my grungies. Plus time to review, plan, research, scratch head...

                      @ Chewie:

                      Not to parse words here too much. but I am curious:

                      " You may obtain a repairman certificate for your own amateur-built aircraft if you built the major portion of the aircraft. The only privilege this certificate gives you is contained in 14 CFR section 65.104, "Repairman Certificate - experimental aircraft builder - Eligibility, privileges and limitations", i.e., to do the annual condition inspection. "

                      I wonder if the "you" refers to you as an individual builder, or "you" in a collective sense meaning those entity or entities aside and separate from the manufacturer.

                      In other words, if I had a twin brother, and he and I evenly split the 51% construction of the aircraft, could either of us indeed still qualityf to apply for said certificate,. I understand only one person can hold it. The " if you built" term can potentially ?? be interpreted in several ways, either strictly individually to a single person, or collectively to a non-manufacturer entity which might be composed of several individuals, perhaps any ONE of whom could apply for the certificate.

                      I do not know. I am not an aviation lawyer, and this is all very mysterious to me.

                        I noticed that ambiguity too and am not 100% sure. Hunch tells me you individually need to be the majority builder, but I've heard of nearly finished projects going for sale with the words "no repairman cert, you can be the builder!" Maybe the application itself would answer that question. Does anyone know?
