Matt, Hobby shop guy, (jim at Dougs in Waldorf) said the RCS 180s are on back order so I had to rethink that plan. I chose to go with the ZDZ 40 instead. A little more hp and a little more $$ but only a couple more oz. Gonna put Hitec digitals in the plane. four 5645's in the tail and a pair of 5625's in the wings. I have half of the servo's but when Jim ordered the others he got the one's with JR connectors and I use Futaba so I am still waiting on the servo's.
