Here's another one for some fearless test pilot......
I'm wondering what the roll rate is over the entire speed range. Ie roll rate from V1 upto VNE say every 10kts. If someone wanted to earn extra brownie points they could measure the actual stick force at each speed. To setup and do this complete might be a bit of a pain but if nothing else 3 good measurements of roll rate and force would work using V1, 1.3xV1, VNE speeds.
I'm working on modeling structure and would like to include this data into it.
