RE: What do you think about JETLEGEND L39?
I recently checked the incidence at the wing tips of my L39 and I was surprised to see that it had 1 degree of positive distortion on the left wing tip. That would explain why it has always needed a small amount of left aileron trim. it also had a tendency to perform better snap rolls to the left than to the right and was very ready to drop to the left near the stall. I was able to straighten this out with a weight to bend the wing tip and use of a heat gun. It could be worth checking this out on all models out there as it may be a mould fault?
The new paint scheme is almost done so I should have some pics next week.
