Servos for 100cc Yak
I am setting up a 100cc Yak. The servos I am looking at are the 7985 and the 7955. Will the 7955 in a single arangement be enough to handle the rudder @ 6volt? With a cost thats not that much different between the two. Couldn't I use the 7955 on all surfaces and have all the torque I need or is there a benefit to the 7985 servos. I have only used the 7985's on a 50 cc plane and liked the performance. What is the difference between these two servos besides the torque?

RE: Servos for 100cc Yak
Optimum set up is 7945 or 7955's for the ailerons (2ea) and elevator (1ea) and a single 7950 on the rudder.

Yes, the big difference is the Titanium gears and heatsink case on the 7940,45,50,55's. All can also handle 2S Lipo with no regulators.
