Thanks for the info, Chuck!
My student did make a 1/4 length motor and weighted balsa piece 3/4 the length between the hooks. We adjusted the glide first, then tried flights with the short motor. Only one was made, because he over wound the motor on the second attempt, and it broke. He didn't have another short one. We did the rest of the test flights today with the full motor at reduced turns. Not great, but it did let us get the model trimmed reasonably. It's flying now in pretty consistent size left turns for the entire flight. The CG is as far back as we could make it and have it fly smoothly.
With the pylons vertical, the wing is tilted, not level. This can't be beneficial, but I wonder if leveling it could make much improvement. Any opinions?
We have one more chance to test fly it Super Bowl Sunday, before the local competition round. I think it may be adjusted about as well as it can, given it has a number of places the wing has slight waviness. It's pretty good, but it's not as true as a few indoor models I've seen pictures of.
Anyone interested can see a two minute half speed slow motion video on YouTube here:
