Hi guys

Anyone have any trouble with standard servos being to big for the alierons? When I screw it down tight it's almost breaking thru the skin on top. Any suggestions on how to fix this I was wondering if it would be ok to just put some spacers between the servo and the wing, or should I break down and go buy some low profile servos? BTW I'm using hitec 605bb. Also I bought a du-bro pull pull rudder system for it today at the lhs I've never installed a pull pull system before any hints or suggestions I understand the concept I just have never put one in before so I would like some advice on installing it or maybe somewhere I could look for some good info.
