Default RE: GP Ryan STA Electric

Gentalmen here you go.The kit and plans are very well laid out and first time builder,so it shouldn't be to bad.One thing I found was my plane turned out tail heavy even with the batteries all the way foward.So first I modified the fire wall so I could slide batteries farther foward.Another thing is that the lading gear wire is to stiff.What has happen if you land in grass to fast it will catch the wheels and ripp the pine blocks out of the wing instead of the gear bending.I would recommend going to 3/32 wire.For me this plane is still a on going experiment to see what I like the best.I also do static thrust checks,watt out put and amp draw at my house before I fly .This way you have that more confidence in the plane to fly. Next I will list batt combo& props that DO WORK!!
R.T.F. 3lbs 8oz Motor; Brushless Jeti Phasor 30/3 &JESA40 controller 8x3000 NimH cells
11x7 204 watts, 1 1/2 lbs thrust,24.5 to23.0 amp draw(well under motors max)
11x8 215 watts,2lbs thrust 26.5 to 24.5 amp draw. These two will work good for the first time flyers. With VERY GOOD throttle management and just flying traffic patterens I have flown 10min.(and these cells are about 3yrs old!) On average you can expect 6 to 7min flights.But it depends on THROTTLE MANAGMENT!.Rite now I'm flying with new cell count of 10x1700 cp cells and graupner 10x7 folding prop.Only have 3 flights but very lively flights.The times have been best at 6min.But wind has been a factor so higher throttle is needed to maintane flying.As for motor mounting I modified & strengthend the mount that came with the kit.So far it has flown very good.Now on to flying.Taxi the plane so you get a feel for how sensetive the tail wheel will be.I also modified the tail wheel by place it forward off the rudder and making a linkage to slowit down.Anyhow this ismy take procedure,up elevator start to add throttle,plane starts rolling along then add small amounts of RIGHT RUDDER as the plane lifts off release elevator and keep the nose down as to penatrate wind.I try to do about 25 to 30 degrese angle of take off.I keep full throttle for about 35 to 40 seconds to get the plane up into atmosphere.Then back off to 1/2 to 2/3 throttle.The radio I use is Hitec flash 5X .I use high rate elevator on take off.Ailerons are set at low during take off.Flying ailerons on low rate very slow rolls so keep the plane some what high.On high rate the roll is way more lively.You may find also elevator touchy on high rates when flying.You can go to low and it will be les sencitve.There is more I can say but don't have time rite now.Email me or post here and I will try to ansewer.Good luck,stefanP
