"I built the Rush in 2 evenings and had it ready to fly on the third day. I am using an O.S. 50 SX, 13-4 APC(not the wide blade though) and 20% fuel. I used all the stock hardware with the only modification being that I installed the rudder servo in the tail and abandoned the pull-pull. In retrospect, it might have been better to install the elevator servo in the tail as well, as I still needed to add 2 ozs of lead to the tail to achieve the tail heaviness I needed for 3D. The recomended CG is 110mm back. I balanced mine at about 125 or about 5 inches back for the first flight. It required quite a lot of rudder to knife edge, would not flat spin, and would not do a wall. I added 2 ozs to the tail and it is now perfect! I am now balanced at 5.5 inches back or 140mm. I think between 5.5-6 inches is the ideal and will be moving mine back just a hair more to get it to really "pop" up in a wall. Amazing that no matter how much I move the CG back, it never gets touchy on the elevator and lands just as easily. I Hardy have to breath on the rudder for knife edge, walls are better, waterfalls are end over end, inverted is almost hands off, slow rolls and point rolls are effortless, and flat spins and blenders are easier. The weight also helped with harriers. With about an inch of up aileron mixed to the elevator, this is one of the most stable planes in a harrier I have flown...........and its only a .40 size plane!! Very easy to hover and torque roll I have 60 degrees elevator travel, 50 on rudder, and 30 on the ailerons and 50% Expo on all surfaces. Basically this plane has the 3D capabilties and handling of a foamy but precision qualities of a pattern plane. It flips around like my little foamies but then does a 4-point roll like a 2 meter pattern plane. I couldn't have asked for a better combination."

Io l'ho seguito alla lettera e mi ci trovo bene.
Ciao,

Quoto in pieno.
