The servos are located in the same holes facing the same way,same servo arms,same length of rod,i really dont think there is any differance there that would cause a problem.As far as not putting enough money into the plane,the only thing i feel needs to be upgraded in this plane is the the two elevator servos,i have two new 645 hitech metal gear servos that are going to have to last for a couple of more weeks,i have other projects going on,i fly warbirds and have never really had the urge to fly this type of model,ive been flying gas for sometime now,im just finishing up a mick reeves 1/4 scale spitfire with a 110" wingspan,which i have almost 4k invested,i have also scratch built a zirolli stuka which flies great,which i did not cut any corners,ive just never had to deal with this servo problem before,and wanted to know the best way of going about this so i would not have to rig the plane to make it fly,i never planed on cutting corners on this plane to save money,id hate to lose all i have into this plane over something stupid,my smartfly should be here today,from what ive read it should work fine,and 8611 servos will be coming within the next couple of weeks.I'm not looking for a cheap way around this problem,just the correct way to do this,so i wont have deal with this again in the near future.I hope no one got the impression that im trying to be cheap.
