Get yourself a radio with good standard servos. I would recommend a JR.

For the bushwacker, I would HIGHLY recommend getting some micro servos. But there are some problems associated with this. While I have seen kits in the .15 size range that had standard size servo's in the plan, most poeple put micros in.

The HS-81 is a good all around small servo. There is a metal gear version which is good when you are goign to belly land or worry about stripping gears. The HS-55 is even smaller and is nice, but the gears can strip relatively easy.

The HS-55 can be gotten for $10-13, then HS-81 for $15-17 (metal gear version for about $23-25 i think).

There is another option, the hs-56. It is the same size as the HS-55, but it has a karbonite gear and has a bit more power to it.

As you can see, these servos aren't that expensive. Your better off gettign your radio with some nice servo's and then buying micro's specific to your application as needed.

Whatever you use, i would suggest using an hs-55 for your throttle, maybe even a smaller (ie,3.6-5gram servo that can be gotten after a little careful shopping. hobby-lobby has them) servo to help keep weight down. Also, the front of these small planes can get pretty tight.

I also recommend trying to lighten the plane as much as possible. Even small weight savings make a difference here.

Good luck. If you need more help, visit the 1/2a forums.
