Hi ya,
Pics will have to wait (sorry
) but it's quite straight forward.
I use the Spektrum SR3100 DSM2 receiver which I fit directly in front of the cells on the left hand side.
The cells are pushed as far back as possible and I also use a foam block to space between the cells and the servo on the right hand side to push them back also.
ESC stays in the normal place - everything does fit (just!)
If I get the chance, I will post a pic but it's not possible at the moment - but I hope this helps.
It is a simple fix so long as you have enough room for your receiver.
HTH
