At last it's ready for the maiden day. Engine is the SK .90, Futaba RX with Hitec 5475s and 475 servos. Iused a Hitec HS 80 on throttle and the HS 81 for the front steering control slaved to the rudder. It came in at 7 3/4 pounds, as heavy as that sounds I was expecting about another pound. It isn't an ARF!!!
