try this link out, he has allot of info listed. I say go for irt, just make sure that you calculate the proper 'G' force that will be applied to the aircraft. Nothing like the maybe .5 G or maybe even 1.5 G that you will experience in full scale aircraft, we really turn and burn these things. Just make yourself a plan and follow it, when you run into more trouble, we'll be right here waiting for you. If you need someone to test fly whatever you are building, give me a ring and I'd be glad to take her up for you.. Good Luck Dude...
