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...
