Hi MrScott, I think i see what you mean, I was sorta leary of powering him up with the left body panel removed to find out for myself, out of fear that the neck would jump out of the housing and cause me to lose or damage some parts.

Now I'm kinda tempted to install a servo in there to control that cam for mouth opening on demand.

Well, i was thinking of hooking the servo up to the cam instead of the cable, this way, the neck mechanism could still open the mouth, and you could additionally open the mouth using the servo.... since i'm not that good at figuring out logic circuitry I would probably have to hook the servo up to a seperate reciever, and hack up an old TX to create an extension for the remote for controlling the mouth, i would probably use the trigger from a pistol grip transmitter for opening and closing the mouth.... this way I'd have full analog control, i could open the mouth a little... or alot.

Just took another look inside my raptor, doesn't look like it's gonna be easy to fit a servo and a reciever inside.... the best mounting point seems to be directly behind the leg box, the only problem is that when roboraptor shifts his body forwards or backwards, the space behind the leg box is affected...... I'm almost sure I could get away with using a micro servo and a micro reciever, but a micro servo wont have enough torque unless I replace the jaw spring with a much lighter spring(which would make it harder for roboraptor to hold onto his prey), and unless I can find a place on the main board where I can pull 4.8 to 6 volts, I'd have to wire the reciever directly between the battery box and the power switch... which would feed the reciever with anywhere from 7.2 to 9 volts(depending on if I'm using NiCds or alkalines).... either way, micro recievers don't tend to like that much voltage, so I would be forced to use a larger reciever with a built in BEC to regulate the voltage flow......... So basically it all boils down to the best option being a standard sized servo and a full sized reciever, and it just doesn't seem that there's enough room.

Well I'm trying to avoid altering the outer appearence at all, I don't even want to make any holes for the reciever antenna to protrude if it's not necessary.... as to that regulator, if i wired my reciever between the power switch and the motherboard with the regulator on the reciever.... wouldn't it also step down the voltage to the mother board to 5 volts????
