Jeff, you are a busy fellow. Sounds like my workshop--or as my better half puts it, "too many projects at once."

I use a JR PCM 10x system on 50 mhz. Have high and low rates on the Road Runner but don't use expo.

I check in my trailer and the servos in my RR are HiTech HS-475BB's. They have been in it for two seasons and seem to be holding up just fine.

Hope this helps.

Rich
