Video....
Start a build log, shoot and post video of the maiden.
Crashes tend to happen really fast. Video allows for more people to take more time looking at a problem.
Where I as a pilot just saw a heartrending instaflip and faceplant, others see CG and control reversal issues. A build log grants perspective and video opens up opportunity to assist.
Try a build log for your next mini. When you crash the forum can try to help. When you fly we will all cheer with you!
