Ok guys, good catch. Looks like its actually missing 2 angled rows of
riviets! That's exactly the push I needed. Nice to have opinions from
people that have been there and done that.
If anyone ever needs an opinion on how to fly a Rebel on half the hp
that most have, and a runway half the length of most that's when I can
pitch in!
Thanks to both of you.
If I run into any issues I might post again, this should get me going.
Thanks
Frank
