Guys, Im running the 7940 (steering) and the 7950 (throttle) in my new Mugen MRX5. I was running a 7955 in my old MRX4X it was tuff as nails, but slow compared to the 7940.
In my first run with the new car and the new servos I finished 5th in the A main at the famed Ft Myers RC car track. The car felt very connected and the servos were very smooth.
Currently I'm running a nimh battery with a plan of going to lipo as soon as I can find one that will fit in the car.
I have my 7955 as a back up but I am on the hunt for some new 7940s these servos get very high marks from me !! I have run Sanwa, JR, and KoPropo servos in the past ... I'm NOT going back.
