I used the following and will explain it as best I can, but any questions please feel free to ask away.
A hitec HS-82MG hiding on the right hand side at the front of the bunker tucked away where no one can see it, a new reversor linkage made and servo mount made. This required one new hole to be drilled and a nut and bolt in it as I used an existing hole for the other point for the servo mount. The servo was mounted vertically, upside down in a home made frame to make sure the linkage was in the right place.
A HS-125MG slim wing servo was used for the regulator, this was mounted under the cab using the 2 flat mounts it came with, they were packed out with a drilled piece of wood for support. The linkage for this required a slot to be cut in the cab floor which was done without much removal of anything and infact only the cab bodywork was removed throughout the entire process.
The battery was chosen for its size and I used a square AAA 800MAh pack, tucked away at the other side of the front of the cab infront of the gas box. This is held in place with industrial velcro which is less affected by heat and it fits so well that it cant really go far anyway.
The RX is again mounted with industrial velcro under the cab floor, just behind the regulator servo, again, a pretty tight fit so it can't go far anyway. This was an "Orange" 6 channel RX from HobbyKing and the casing was removed and replaced with large heatshrink for a case to keep the size as small as possible. These RX's are only about £4 each!
The switch was a stanard charge harness type switch and was mounted using a bit of tin from a bean can on the back inside of the cab, this required 2 x 2mm drill holes and 2 x 2mm nuts and bolts to hold the switch mount in place, the switch was also held in place with its bolts through another 2 x 2mm drilled holes.
Finished off with a little bit of black satin paint where the brass was cut and the switch mount was put in.
Works absolutely fantastic and can barely be seen, very pleased indeed. If I get chance I will post up some pictures later. Runs like a dream, very "chuffed". Very pleased i opted for 2 channel as I found the single channel on the reversor extremely sensitive.
I do hope this information helps someone else out
