Hi James, When I glued on the fin, I used a laser light, but from looking at it, looks like the fin is on straight, but i can look at it again.

It's just a thought. Not overly sure what would cause rotation with the wings unloaded like that.

I have a good reason to believe it was that left stab was off. So with that left stab having up elevator, relative to the right one, it would cause it to roll to left and for the left wing to drop.

I let you know wednesday if the problem is fixed!!!

UPDATE!! great news, that problem is gone now. It was that one stab that was making the left wing drop!

Now, time to burn gas!!

WOW, very glad you figured it out. I cannot believe .5 degrees made a difference like that.

Oh yes!!

It flies like a dream now!!

This is now my IMAC plane. I keep it in my trailer as my back up, and last week, I went to a contest in Little Rock, Arkansas...

On that Friday, I was flying my Dalton 300 ML, which is my #1 plane, has about 300 flights on it. On Friday, I flew it once, did the INT sequence 3 times, then landed her. Refueled her, and took off again.

I did the sequence once, and then started to do a 2nd sequence, I did a snap, and then heard a God Awful sound. I immediately landed her and noticed there was a problem....

SO, this airplane became out of commission, and I brought out the Yak.

This airplane, unfortunately, was not trimmed out. SO is spent most of that Friday, trimming her out...

The biggest issue I was having with her on Saturday, were the snaps. They were not dialed in.

Someone did take a picture of her, while she was in the sky....

then, for the past 2 days, I have her pretty well trimmed now!
She is ready for some more.


I ended up 5th at that contest.
Let's see how she does next weekend in Byram, MS.
