I've recently installed two Graupner Speed 480 ball raced motors into my Twinjet. It's always run fine on a Jeti JES 350 speed controller with Speed 400 motors, but is now cutting out after a few minutes flying. I'm using a 2300maH 8cell nicad pack. Could it be an overheating issue? I'm using Cam Speed 5.5 x 5.5 props if that's an issue. Help! the weekends going to be sunny and we don't get many of them over here.
Chocky.
