Makes a difference Review by William Rademacher
I used this as a replacement for a speed control I was already using on a mega jet V2 motor. I thought I might follow what Grayson recommended as a speed control size. It;s now a different airplane. The airplane is a profile B-58 foamy. It now goes straight up, loops from level flight and rolls like crazy. It sure made a big difference in performance. (Posted on 11/5/2015)
