I would show my model airplane, but I'd rather give specs. ESC 2200kv to 1180 kv ESC engines. 1 engine. This is a twin pack. So the single engine runs on 7.4 volts TATTU battery. I am not sure if this was right. It beeps but no engine start. 650 mAmp/hours. 3.6 ibs. to the model airplane. xt30 connector to the tattu. Really small battery. I don't think the 11.4 volts will do it. It will burn it up.
