Recently I posted a thread regarding Hstab incidence and elevator trim throws. It was a GREAT thread as there were lots of ideas and input, all of which contributed to me finally being able to get a stabilized, FULL flap, approach at about 50kts in my 4A. I was never able to get it stabilized...

Absolutely, although I question your definition of "cheap" 😉😆

Another performance datapoint. I went on my first (short) cross country in the Bearhawk yesterday (about 100nm/185km) to a flyin. 24"MP/2000RPM 3500' 11C 120kts TAS 10.5gph/40 lph LOP Good enough for me Note that I have girly size 7.00x6 tires so that makes a difference. I'm not manly (or...

110kts true. About 106kts indicated (I think I was around 3000' asl). I'm going to redo my cruise/performance testing with the adjusted Hstab incidence and figure out my optimum xcountry settings.

Well, you guys rock. Trim throws: it turns out I only had 1 1/8" (28mm) of "up elevator" trim throw. The way I have the Ray Allen servo is connected to the trim arm is through a custom pushrod, threaded at either end, and fork ends (the trim servo is mounted on a plate underneath the HStab...

Hey Jared and Jonathon Thanks a lot for your input. It is greatly appreciated getting advice from two of the most experienced Bearhawk guys around. Ballast: I do have about 25 lbs of ballast (tools and The Claw tie down kit) tied down in the aft cabin, but maybe I should add some more...

Hi all I've been flying my scratch build 4A since February (except for a three month, 17,000km/10,500mi across Canada campervan trip this summer) and have a question for those of you who have a.) set their horizontal stab incidence to something other than what Bob recommends in the plans and/or...

Yup, No problem. I even had the empennage all mounted I cut up some pool noodles to protect the leading edges of the tail and landing gear from stones and put bubble wrap on the windscreen and prop.. ​

I chose to make a full size panel removeable. All four sides are held on with countersunk #8 screws into nutplates. The TOP of the panel has a joggle such that it slides up underneath the glareshield skin. This approach gives me a TON of working space under the panel from the outside and you...

Hey everyone I posted this to the Bearhawk Facebook group, but then realized not everyone uses Facebook (and good on ya). ************************ Well, it only took just under 14 years, 5200+ hours of labour, and a couple of months waiting for decent flying weather, but I finally did the...

Hi guys I've seen lots of VP-X issues discussed on the Vans forums but not one quite like this. System description: O-540, Plane Power 60A alternator, B & C 40A backup, EarthX900 battery, VP-X Pro, G3X 460 and 470, etc. The actual devices don't really matter as you will see in the problem...

These are from several years ago (my Bearhawk is finished and I'm just waiting for a decent day to do the first flight .... in Ontario, Canada .. in November ... riiiiight...) I used split corrugated conduit zip tied to the stringers under the floor. I was able to put it in THEN run wires back...

Hey folks Pretty specific title, i know. Here's the problem: I have an O540-A1D5 with Bendix SL6N-204 mags. I also have a Garmin G3X system using the GEA24 engine interface system. One of the default sensors you can use with this setup is the UMA T1A9 Hall effect rpm sensor. It screws into the...

On my scratch built I fabric covered the area up to the top longeron on the outside and made a couple of 0.020 aluminum covers for the inside (the arrows in the picture below point to where the covers go). They are just held in with Velcro. Note that only the rear cover is shown in the pic. The...

Temps and humidity this week preclude any painting (I'm using Stewarts) so I'm picking away at other jobs and ideas. Back when I built my flap handle I knew that I wanted to modify it so I didn't I have to fold my old man body in half to raise and lower the flaps so I added secondary handle...

Well, painting has finally started. Temperatures in our part of Canada are now warm enough to work in our unheated hangar. I built up a removable paint booth with giant tarps, floor model fan, furnace filter, and loads of light. I'm using Stewarts and boy-oh-boy has that been a learning...

Prep for paint continues while I await warmer temperatures. Finally finished the fill/sand/fill/sand thing chin scoop, nose bowl, and exhaust air dam. Now it was time to figure out the masks for my paint scheme. All you guys who used single colour or straight lines on your airplanes are WAAAAY...

Sloooowwwly working on my fiberglass parts. I HATE working on fiberglass (actually, it's the repetitious fill/sand process that I hate). The past few days I've been making my nav/strobe fairings for the wingtips. Turned out pretty well although I do have a few more rounds of fill/sand before the...

Man, I'm glad that is over with. I probably have 60-80 hours into these seats and they are FAR from perfect. However, I saved hundreds and hundreds of dollars and can now honestly whine to anyone who will listen that I did them myself :-) The front seats have three-layer memory foam bottoms and...

While waiting for a couple of replacement parts for my HVLP gun (seals and such) I figured I should bite the bullet and do the upholstery for my seats. Now, I know NOTHING about how to use a sewing machine or doing upholstery, so what could possibly go wrong? My inspiration came from our own...
