Hello all, this is my first post and I'm wondering if I can draw on some of your knowledge to solve a problem I have. I built my first aircraft, a "Versa Wing" from plans a fortnight ago with the following electronics in the power train bought from www.giantshark.co.uk.
8x4E Sport propeller
HobbyWing Flyfun Brushless Motor 30amp esc speed controller
E-Power 2210/25 1500KV 20A Brushless Outrunner Motor
Gens Ace 2200 30C 3S Lipo Battery
Everything has been going peachy with many successful high speed and energetic flights, I've even connected some LED's on the balance port and have been doing some awesome night flying. Today however, when I flew sans LEDs and with a freshly charged battery, I found that I was unable to produce the power which I have done in the past.
The wind was 20 knots and I was struggling to overcome it with full throttle set. I could hardly fly the aircraft back to me without losing height. When I landed I found the motor was hot to the touch and the speed controllers heat-sink, which I have exposed through the hole in the bottom of the model, was also slightly warm also. Outside air temperature was 10 degrees. My housemate also built a wing and we tried the battery in his and found it was producing full power.
Does anyone have any ideas what could have caused this sudden change in performance? I'm wondering if there is a problem with the speed controller but I don't understand why the motor would heat up also.
Many thanks for any assistance anyone can offer.
