megapirate

Has anyone been able to set a max or min limit on the servo for a tricopter when using APM or Megapirate? When I push full right on the servo it gets stopped at it's endpoint and draws a ton of current. Would setting the limits on the radio fix this?

Can you guys tell me if this is everything I'll need. I'm trying to build a multirotor for FPV with a GoPro Hero 2. Also, what props would you suggest, and is it 2 and 2 LHR RHR or all the same? Thanks in advance...
