I don't think that it will surprise anyone that the FlyBaby will be my first attempt at building a (real) airplane, so this question is more on the general side. How does "licensing" work? I have read things that allude to each set of plans being serialized and that is your plane's serial number and you have to purchase extra sets of plans if you want to build more than one. Am I reading that correctly ? (not that I have a problem with that, for the $65 "license" the FlyBaby is well worth it, and when I design my plane I will of course want some sort of royalty for the trouble) One more; How does the FlyBaby perform on the A-65? I have done a little digging and it seems that I could get a Lyc O-235 (100-110 HP) for about the same price. I can't seem to find any 85-90 HP engines in any condition, should I infer that they are more popular? Any recommendations? (price is a factor of course, I have been looking at engines in the $2000-$4000 range that require various amounts of work) Ok, sorry this is long but one more ;| The Lyc O-235 weighs in at 213-218 lbs (according to Textron Lycoming home page) how much does the A-65 weigh? Will my CG be ok as-is? Sorry for the long questions, Thanks, Scott S
