I've been flying a couple of prototypes here in the UK for a while now, tried both options IC and electric. The IC was powered by a Thunder Tiger 20 and the second was electric, my personal preference was the electric. It stayed rigged up in the back of the car and was just a matter of plugging in the lipo. The servos used in both set ups were 2kg mini's.
The flying have a look at the video click on the link below.
