Xtra flyer,I appreciate the commemnts.As I said in a previous response,I will start of with my Saito 150fs,as I need to put some time on it.Then I have two Saito 180 GKs that I will use (one at a time of course).I got the T-craft,in order to have to "run in " the Saitos and my Moki 1.8.I have a DEhavilland Mosquitoe kit,with a 109 in.wingspan that the Saitos will go in.I, too extended the eng.rather than add nose weight.I used one 100in ounce servo and installed the elevator pushrod as per instruction manual,but using two servos on the elevator is a very good idea.On my other planes,most have a servo for each elevator.My other arf is a kankge laser 2000 which,I will start.THanks again to all for the responses, Bob R
