A first attempt to post pics!
Pic1 does not show first speaker fixed (velcro) on its side against the angle of the rear hull plate betwen the motors and beneath the power module shelf. Trying to get speakers roughly where the original engine would be.

pic2 shows smoke unit in relation to motors etc, 2nd speaker facing towards front of tank sitting upright. Will need to tidy wiring to ensure none touches the smoke unit!

pic 3 shows speed control, amplifier and auxiliary boxes + receiver. All velcro mounted. Auziliary box mounted on hull side using U shaped plastic profile to raise it beyond the protruding bolt heads in hull side. I intend to locate recoil box either on hull floor or on amplifier module.

Not a prety sight but it does appear to function as required!! I intend to put the recoil box either on the hull floor or on top of the amplifier box.

pi4 is overview from tank front. Black matting covers batery terminals to avoid accidental contatcs!
