I must be doing something wrong..I am flying my Sig 1/4 Cub with the new DLE 20...perfect...sure I have to fly it on the wing..but thats what I got the Cub for...circuits all day long at scale speed and the challenge of making it look real. Only thing I would change is to get say a JTEC wrap around muffler to reduce the amunt of cowl I had to cut out with the standard muffler.
