Hi all, I will start with caveats and disclaimers: This is my first build, so input from all is welcome! This is an OLD kit - delivered from Avipro to the first owner in 2006. Some work was done on the fuselage by that individual (landing gear install, tailfeathers initially fitted), and the...

Minor milestone: I finished up the plumbing for the main and aux tank in the right wing. I was a little puzzled about how to finish off the vent for the aux tank. I ended up bringing it outboard to the last bay, and then bringing it down to an under-wing vent (Cessna-style). I will have access...

Tubing Bender for 3/8" Fuel lines: Imperial 368-FH (YES) vs. Harbor Freight (NO) I am working with two tubing benders: Imperial 368-FH, and a Pittsburgh model from Harbor Freight (SKU 3755). Both are lever-action and claim to handle 1/4, 3/16, and 5/8 inch tubing. The HFT tool will bend to 180...

​​I hit a stumbling block last night when test fitting the upper strut ends to the steel straps that stick out the bottom skin of the wing. The strut ends contact the wing skin and prevent the holes from aligning properly - by eyeball there's ~ 1/16" interference. ​​ I notice that the strut...

Hi all - Sometime this summer I'm planning on match-drilling my A-model QB wings to the fuselage, and trimming/drilling the lift struts. I've scoured this forum and the other Bearhawk sites, and have found what I think are the most recent instructions for my (quite old) kit: Drilling wings to...

Hi all, for my A-model 4-place QB wings, I'm wondering how much rotation the aileron bellcrank needs? The rear-facing arm interferes with the rib (photo below) when rotated in the "aileron up" direction. The build manual mentions "In a few early kits there was a little interference..." and mine...

Hi all, I've installed the aileron cable fairlead in the flap torque tube support bracket at the wing root, and I'm finding that the fairlead collides with the outboard surface of the root rib. This pushes the support bracket over (toward the wingtip) and causes the flap torque tube to bind up...

Well I tried to test-fit my aux tank from the top side of the wing, before cutting the hole in the bottom skin. Unfortunately the tanks (including the welded fittings) seem to be wider than the spacing between the ribs. The Beartracks article from 1996 says the tank should be 13-1/4" wide. The...

It's time for me to cut one of my 4-place QB wings (A model) open to install the aux tank. The latest builder's manual at bearhawk tips recommends against using snips and seems to caution against using a die grinder. The older builder's manual (PDF version) mentions using a jigsaw, but as that...

I've just become the proud owner of an A-Model 4-place kit. A bit of work was done on it shortly after it was delivered in 2006, but it's otherwise been untouched and sitting in storage for the last ~10 years. It became obvious my 2-car was too small for the build + storage of everything, so I...

Hi all, I'm doing a prebuy inspection on a partially-assembled 4-place QB kit next week which a neighbor has agreed to sell to me. It's an A model, circa 2010, with a fuselage number in the mid-20's. I'm hoping to find a packing list from Avipro in the paperwork that's with the kit to help me...

I'm getting close to pulling the trigger on purchase of a 4-Place QB kit, but need some info on rear seat area. Is it big enough to fit 2 "FAA-standard" adults? My wife and I visited a completed BH recently but only tried the front seats (which were great!). Unfortunately we didn't think to sit...

I'm considering taking the plunge and starting a 4 place QB build. I have a 2 car garage, 19x15 feet. Would the fuselage fit for some of the build, maybe up to the point of rudder and engine installation?

Hi all, Dave here. Private pilot for many years, flying certificated light singles. Considering a 4 Place QB kit as an alternative to a 182 or Skywagon. It would be my first build. I'm good with engines and electronics, but my attempts at welding have been pretty comical, so the kit route is...
