You are correct. I had some 30 oz servos and embedded them in the dorsal surface of the horizontal stab with a short linkage. I had some thin sheet aluminum and a small pan brake that I used to bend the servo covers. I used BVM heat shield to cover them and the dried ceramic blends right into the color scheme.
The other modification I made was an additional front hatch cover. The front area is designed for batteries and I just couldn't get my fingers into the area with the small access in the front former. I placed my ECU battery on the nose tray, my dual 1700 mAh Rx batteries on the front of the former that holds the nose gear and located the Rx on top of those batteries. All the switches are also under the front hatch cover where I also mounted my antenna.
My thinking is to keep all the radio gear (RX and batt) in the front hatch and all the turbine gear (ECU, pump, solenoids) in the main hatch. All the turbine wire and tubing runs down the right side of the fuse and all the radio gear runs down the left side. Trying to keep as much separation as possible between all the components.
