Hi Milospozar,

yes I did finish the plane, and the maiden flight is about 2 weeks ago now. I did need no trim weight at all, c.g. is perfect. Engine still runs on the rich side, and turns a 20x7 prop only about 6.400 on ground. I expect it to reach about 6.800 - 7.200 after about 1 or 2 more hours, I still consider to change to 20x8 prop.

The Gee Bee does fly very gently, but by no means is overpowered, just ok. You need quite some right rudder for take of and especially during inital climb when airspeed is still low. Additionally, the rudder of my plane has some built-in warp [], so it is a bit difficult to say what is neutral position...

I needed some little left aileron trimming for level flight.

Landing is easy, the Gee Bee Y slows down quite fast if throtteled down resulting in a nice descent. Flaring out is no problem, the plane has enough reserve in speed to make a decent 3-point landing. The spring loaded landing gear has worked fine so far, only I had to use self securing nuts instead of the delivered bul**hit cap nuts on the wheel axles. Of course I use standard 6mm whell collars to keep wheels in place, not those stupid plug wires. Another thing which bugged me was that the delivered steel pushrods to connect servos to the elevators and ailerons where so brittle that they broke immediatly as I tried to adjust their shape to fit. I replaced them whith self made 3mm wires. Last, in my kit version, it was intended ot place the rudder servo close to the c.g. inside the fuselage and use 1mm pull-pull-wire system to operate the rudder. I decided against that and made room for the rudder servo under the horizontal stabilizer fin close to the elevator servos. This paid back as I did not have to hassle with extra tail weigth. Of course I also was able to set the proper c.g. postion by shifting the glow driver battery to needed position, which is now about under the pilot´s position, same as battery pack for receiver.

The Enya VT240 is operated with the dummy engine, but I have cut with the dremel tool several slots into the cowling aft of the cylinder heads to allow the heated air to escape on shortest way. Exhaust tubes are routed downwards to the tunnel built in to the belly of the firewall. If you like, I can send you pictures, it doesn´t look too bad. The engine fits perfectly under the cowl, and sound is just the best I can imagine for that kind of plane!

Save landings,
