After crashing my EFXtra I had a lot of left over parts. I ordered a Multiplex Dogfighter (actually 2 kits) to put the parts in.
I had to move the stock motor mount supports back into the fuselage to support the large 3536-1780KV Aerostar Outrunner Motor . I ordered a motor mount from Custom RC Parts, and use a soldering iron to cut out slots to move the motor supports back,
I'll post more when the motor mount arrives.
