Thanks osterizer, One thing for sure it will be rock solid with direct contact mounting. dooleyje, that is a good point worth mentioning as I got so caught up in the servo mounting, I haven't even gave that any thought. My Raptor uses a 4 cell Nicad pack so the servo voltage isn't a problem. As far as the supplied plastic servo screw nuts, what I did was removed the bolt/nut that goes thru the main shaft/gears at the bottom, then removed the 4 screws that hold in the upper bearing block/with bearing, pulled back the anti-rotation guide to clear the anti rotation pin and then turned the swashplate so it comes out of the slot. Then carefully pulled out the entire head assembly straight up and out of the upper main frame assembly. Then I went ahead and installed the 3 swash plate servo's as per instructions. I honestly could not have done it any other way. I was able to have the whole head out and sitting on the table in about 5 minutes. Once everything is out of the way it isn't bad at all. I had to trim off one servo arm as well as one of the servo screws that exited out the plastic servo screw nut as it was dangerously close to the main shaft (barely see daylight between the 2) I could see a glitch develope that would be almost impossible to pinpoint without having the head removed and being able to look straight down from the top side. Not to mention you get to seperate the main and anti-rotation gear to apply a couple of drops of oil in the one way clutch that seemed to need it. It works best to install the 3 swash plate servo's before you install the motor and other things that get in the way. Also to install the motor I simply loosened the back 2 screws and removed the 2 middle and 2 front screws which hold the lower frame to upper frame (5 minutes work). That allows the lower frame to fall down and open up like a jaw and gives you total accessability to the motor mount plate whereby you need to enlarge the one hole and the slotted one anyways. Then screw the motor down slightly and put her back together You will have to put it back together to set the backlash, then open her up again to snug down the motor mount bolts tight (loctited). It sounds like alot of work but I fought for an hour just trying to get 1 motor mount screw in without success. This other way I had it done in 1/2 of the time. Ace9
