Yes they are pretty good. Dewoitine made several models of planes so 1.20 70 inch tells no one what model of Dewoitine you have. The two I mentioned are very different planes. The 520 was a WWII fighter. The other one I mentioned was a high wing mono plane, Parasol, designed in 1920. The D.27 The D.27 could be flown with standard servos but I wouldn't even try them in the 520. I wouldn't use standards in the D.27 either but it could be done. I like both planes and have given thought to building the D.27 at one time. Really ahead of it's time but had some problems. Very cool plane though and make a great model.
