ok, so my son and I have spent many hours building a nutball. We followed the plans from FT pretty closely, the only extra we have on the plane is some tape to color the wing tips. Our electronics/power are as follows:
8x4 Propellers
Turnigy 500mAh 2S 20C Lipo Pack
hexTronik 24gram Brushless Outrunner 1700kv
Hobbyking SS Series 25-30A ESC
Due to some back orders at hobbyking I chose a different motor than the original spec, I assumed this motor would simply be more powerful.
Basically, the plane seems very under powered, it will drive around the field like a car, gets off the ground for a second or two but cannot hold anymore than 10 inches of altitude.
We have a Turnigy 9X and I have a feeling there is an issue with the throttle communicating with the ESC. I have tried several times to re-calibrate the ESC using the technique described by Josh Bixler in the video but still the throttle needs to be movedup to almost 50% before the motor start to turn. I have a feeling I may only be getting 50% power out of the motor which could explain why the plane will not fly.
FYI: I have also tried the Turnigy stick calibration process...no change.
Any advice would be appreciated! Do I have the wrong motor, wrong ESC or some sort of calibration problem...
