More on this piece of junk.
I don't know if it is the construction of the airplane or just the design of the plane altogether. This plane flies like crap! It is very sensitive to throttle inputs. Too much and it climbs like hell and just a touch less than that and she dives on a 30deg. from level attitude. This makes it very difficult to land since it becomes very "baloony", I mean it is rising, falling, pitching.
I have tried flaperons, but that wasn't that impressive to help with landing. The only effort that paid off was the different prop sizes I tried. I have been running a 12X6, the top limit according to MECOA's charts for the GMS .76. The smallest prop is a 11X7 reccomended. I tried MA11X8, TF12X6, MA12X6, and a APC13X6. The later was the best for handling the plane.
The 13X6 had a much more predictable attitude for landing and accending. The 11X8 was good for cruising around, but if your were to get in trouble and had to abort a landing, you had little bite on the air to pull you out. I proved that tonight. Finaly, the 12X6 was ok, but still to fast for this plane for landing.
The engine tuning was near spot on, or within a click or two of perfect (finaly), and the GMS .76 liked the bigger than reccomended size. 12X5 or 13X4 would have been better, but not in my inventory.
The only modification I have made that helps in controlling the plane was getting rid of that ridiculus elevator. I found it to be waaaaay toooo small a surface area to control pitch. The plane would take nearly the entire runway to lift off. I had a set off "flaps" laying around from my Ultra Stick .60, so I modified them by cutting about 1.5 inches off the 90deg end of the flap. I built up the end with balsa, and sanded the work smooth. I finished by covering the newly formed elevator in the color scheme of the fuse.
The following flights were 100% better than before for pitch inputs because of the increased surface area. I highly reccomend this mod, unless you don't mind pileing itno the fence at the end of your runway.
The last mod I'll make is to put a Fults nose wheel in place of that wellfare piece that comes with the kit. I understand the reason for softer landing gear, but the nose wheel is too soft for me. The rear struts are at the limit of being too soft, but I'll leave them for now. The other issue is the design of the control arm and control rod for the nose wheel. I did not build this plane so it would not have been this way at all, but the control rod is only bent in the shape of an "L" and falls in the outer most hole on the control arm. This is not cool because the vibration from the field bounces the control rod right out of the arm and the plane spins out just before resting post landing. I'll fix that also.
For $105.00 the plane is ok. But steer clear of this one and buy an arf. It's worth the extra 40 bucks. It's a trainer and handles like one, but the other planes like the Tower Trainer and simular will do you better.
