  • Bill;

    I just read your post about Props on a Husky. What prop you installed on your Patrol?

    Hello Brooks!

    A very good friend (the guy who went through the Husky's, actually) is building a Backcountry Super Cub. He's installing an IO-375 on it. He had a nice 2 blade MT for that build. I had a 76" Hartzell that was pulled from my Husky, several years back, to eliminate recurring AD inspections. I sent the Hartzell to a prop shop, for overhaul and replace the hub, intending to use it on the Patrol. Owner of the prop shop called to tell me that my hub was NOT subject to the AD and that the prop was in great shape. It would be back to me quickly.
    At this point, I have a fresh overhaulled 76" Hartzell and Ron has a fresh overhaulled 80" MT. A bit of research suggested that the stroker engines (IO-375) don't do well with light weight composite props. A call to the engine builder to discuss prop selection, had him stating clearly that he'd rther see the Hartzell on the engine, instead of the MT. Ron asked if I'd be willing to swap my Hartzell for his (gorgeous!) MT. Well, the MT is lighter, it's beautiful and Ron is the most generous guy I know. So we swapped.
    It took a while to answer your question, didn't it? My Patrol has a really nice 2 blade MT propellor. It pulls strong and is smooth as silk. I would have been perfectly happy with the Hartzell and I'm certain that it would perform equally.
    We have a really great brotherhood of fliers and builders around here. Sometimes a part swap or just an outright donation of a piece is just what's needed to help a brother get his plane further along. Kind of like sisters swapping shoes, to complete an outfit.
    On a whole different subject, do you know Art Soileau? He stopped by my hangar, after seeing me land. He lives about a mile from me. Art retired from FedEx a few years back. He was flying 777's when he retired. I'm sure you guys are a very large group, but I figured there might be a chance you might know him.
    Great hearing from you Brooks!

    Bill
    Thanks, loved the fifteen year experience, and it's a great design. Natural float plane, its pitchy, but you get used to it.

    Ah, you're a builder for sure. The real appeal is the building process. The plane, at the end, is a bonus!
    Funny that you mentioned the Bearhawk being 'pitchy'. A close friend built a very early quick build 4 place. I got to fly it a good bit. Anyone watching my first few landings must have been very amused. I fought pitch oscillations for several landings. As you said; you get used to the sensitivity. When I mentioned the pitch sensitivity to Mark, he (of course) claimed no knowledge of pitch sensitivity. He added, however, that the airfoil shaped wood adders did eliminate the issue. The new Model B comes with airfoil shaped ribs, on the tail surfaces.
    I haven't flown a 4 place with the airfoil shaped ribs, but I can say that the Patrol exhibits no such pitch sensitivity.

    Bill
    Bill, WOW, didn't realize you were so close to first flight. I'm excited for you!! Frustrating knowing you could, but Can't. We are there now with the WX.

    Here is what I have--24/24 @ 7000 155 MPH TAS and @ 3500 141 MPH indicated. At 69% power-138 MPH indicated @ 3500. At 23/23 @ 5000 148 MPH TAS. Stall @ 3500 ft 42MPH indicated, no flaps. was extremely gentle and due to a slight roll issue it fell off to the right a bit. ( these #'s are a combination of mine and Dennis' ) They could change slightly once rigging is complete. Were close, but it appears we might need a rudder tab for trim. The vertical offset seems to be greater than necessary and we have been pulling the back half over with the wires and that has helped a lot. Our flights are mostly at 75% power for break in, so we haven't explored slow flight much. Take off performance is awesome with the whirlwind prop and I'm getting 12 to 1500 fpm in climb out with 85 to 90 indicated and that's not full power most times. I'm not one to throw in all the power quickly, at least until I get some time on this engine.

    Another huge issue is the flaps, I can't use them past two notches. I did manage 3 twice, but at 55 indicated and wallowing around low and slow on final, trying to trim so i can take my hand off the stick for two hands on the flap, well you get the picture--not good. Anyway it was a nice and short landing around 3 to 400 ft. We've extended the flap handle as much as we could for room, 3 in., but I've only had one flight since and didn't get the plane slowed enough on the first landing and the 2nd one back home was basically an emergency flight due to a battery issue. I was loosing it and my Skyview was threatening to quit so I just wanted on the ground ASAP. ( Lady DY pretty much yelled at me the whole flight home and a big red line across the screen said "AIRCRAFT POWER LOSS". ) We have dual P-mags, so the engine will run without battery, but only above a certain RPM, which is about 900 on the ground. As long as your inflight idle is above that your OK. Shame on me, I haven't tested that yet, thinking not having my battery would ever be an issue. In 28 yrs of flying, it never has. Anyway, four notches is an impossibility for me I'm afraid and I'm really disappointed in that fact. I'll never be able to get full use of the plane, but I didn't have any before so 3 will do. My point is the landing roll should be really short for those of you who can get the 4th notch. The rest of us are going to have to practice with 3.

    Mark asked us once for as many photos as we had of the project, they were trying to put together a better build manual. I told him careful what you ask for and sent him about 3000 photo's. :rolleyes: I tried to keep this a short as possible, so sorry if it's too much of not what your looking for. Because of the battery issue, just happened yesterday, I am grounded until I figure out what went wrong. We have 12 hours on the engine and I think not too many more and I'll get serious about exploring all she can do. The moral to this story is you can tell your friends it's an awesome little bird that really preforms. In my opinion it was well worth the time and $$ spent. Donna

    Your welcome Mr. Bill.☺️ Battson has a post on how he extended his flap handle. Apparently he has a lot more room to extend further than we could and he is very happy with the results. Part of my problem is my seat is as far forward as you can get, which puts the flap handle at a closer spot in the pull. Meaning I'm losing my leverage. Yea, a trip to the gym, or it's time to get out there and start cutting, splitting,hauling and stacking the wood.🙂

    A thought just entered my empty mind. If, after much effort and adaptation, you're not able to pull the last notch of flaps, why not retrofit an electric actuator? Wouldn't be hard at all. Maybe a project for next winter!

    That’s a good thought. Somebody else mentioned retrofitting a hydraulic system. I can’t imagine it, but they did. I wish I had realized the problem earlier. Seems it would have been a good thing to address when building. Another thought is finding yourself in a position where a go around is necessary and not being able to release the flaps after adding power. I think electric would come in handy in that situation.
    Just how did you accomplish the smooth tape? small short pieces?
    Bdflies
    Bdflies
    Yep! Several short pieces that overlap. Smooth each one down, before starting the next one.
    Greetings Bill;

    We met at Oshkosh this year at the Bearhawk Dinner. I read your post regarding the Keller Flap, and sw that you have quite a bit of experience in a Huskey.

    Because you sold a Huskey to build a Patrol, I am curious on some specifics on how you think the Patrol will compare with a Huskey's performance, and if you are doing anything special during the build to enhance it. I know you are considering the Keller Flap in the future. But right now, during the build, what are you incorporating?

    Hello Brooks!

    I remember you well. I LOVED my Husky. Great aircraft! Mine was an earlier A-1 model, which meant it was pretty light. I have about a hundred hours in the A1-B and A1-C models also. They're a bit heavier and have a different wing. For my money, the lighter, early models perform better.
    I think a stock Patrol should perform very much like my Husky did. If it's a little faster, great. If not, no big deal. I'm all about short grass strips. My project came with a Catto prop, that I sold. I'm using a MT constant speed prop. Other than that major change, I'm just trying to keep it light, without sacrificing creature comforts. If I can stay below 1200#, I'll be happy. That should be doable. The Husky has great brakes! I removed the single piston Grove calipers and bought a pair of their 35-6A calipers and installed a set of .625" bore master cylinders.
    You're probably wondering why I sold the Husky, if I liked it so much... It's about going Experimental, rather than certified. My A-1 had steam gauges and a Garmin 396. That stuff worked fine and got me anywhere I needed to go, but upgrades, for certified, are expensive and limited. My Patrol will have a G3X touch, with a G5 for backup. I've installed roll and pitch servos, driven by the G3X and Garmin's 307 control. I'll have the AOA indicator as well. Remote comm and transponder (ADS-B in and out) will be controlled through the G3X.
    The 0 smoh Lycoming o-360 will sport a Slick mag and an Electroaire ignition system.
    I'm thinking of the Patrol as a completely updated, brand new Husky. Mark would probably be insulted by that statement, but it's a great compliment in my mind. I'll fly with the stock flaps and see how that goes. The slotted Keller flaps are a real possibility, but not a for-sure thing.
    If you've got any questions, please don't hesitate to ask!

    Bill
    Well I just ordered the single piston (2" calper) Groves. Sorry, bet somebody else will need them.

    Great news! As lng as progress is made. I really wasn't looking forward to removing the wheel/brake assemblies, but as I read your thread, it clicked that it might be good for us both. And, mine are the 36-2A 2" calipers.
    As you said, someone will need them.

    Thanks,

    Bill
