thanks for taking the time to reply. i built the plane extremely strong. used light weight slow cure epoxy mixed with flux that makes a hard bond. engine is rated at 5 hp. 40 lbs of thrust. plane is the 80" wingspan by Midwest, not quiet considered 1/4 scale but bit smaller. engine and plane without the servos and battery weighs about 16 lbs. i heard so many good and bad things about servos. I'm not too sure what brand to use now. i heard DAD servos would do the job, but i also heard that they gone out of business, so service is out of question. i guess i need to attend some of these meets that they hold around here and see what other people are using.
