Is your hang point right? Looks like you might be leaned back too far. The thrust is pointing upward quite a lot.
You need to bring the center of thrust more parallel to the ground. Good job regardless 10 to 15 degrees us usually what is used for gas units, Move your connections back bit if you can.
Thanks for the hint … that’s what I noticed on the video. I’ll fix that
Did you have pre built batch 4?
no, it was a kit. Thanks to the forum I could preorder everything. and thanks to the good description of Etienne, I got my battery ready in june
Wish I’d done that but was a bit queasy about spending $1200+CDN and shipping and tax for batteries until I had the motor ordered.
