RE: Electronics do not fit in TLT-1 Max Climber - is it possible?
I use a Futaba micro receiver and a futaba MC-230 ESC in mine. I have room to boot but the Futaba ESC has a very small footprint.
Im pretty sure you should be able to fit the Intellispeed ESC on it though, but you might need to stand it (or the reciever) on its side.
Worst comes to worst you could always stick the receiver on the side of the chassis, or ontop of the rear servo plate (if youre not going to do 4ws that is).
