Success! Wren runs beautifully. Didn't have an 2c lipo specifically for the ECU so used an old one I used to use as a flight pack. As you will see in the vid.... The pack takes a hammering during start up. On that pack, I could only get 2 cycles before the Ecu said 'nope!'. Will now measure up what space I have in the nose of the hawk and order up Ecu and flight packs...
(David, I will measure up the hornet's dimensions for you)
