Mike,

Today, I also use .015" wood for the 10.25" motor stick and the 9" motor. The point of the video is to show that Treger in 2013 ECH flew with a significant amount of wing twist at launch.

Fast forward to the new rules. I am concerned with the 7" motor stick and the 6" motor. On my model, the 6" motor will overlap with only ~4.5" of the wing chord. So, I will only have at most 50% of the twist as before if I use the same wood. ( I believe it will be much less than 50%, like 25%.) I am questioning if this decreased twist will be enough.
