Ya another lighter pilot had a similar issue as you (he was 130lbs and also using the large battery)
I think i was so focused on designing it for us big Americans that i really over looked making sure it was still nicely setup for the “lighter weight” guys out there (you’re not ever really light weight though ) I would say right now the middle point of the bars would be best for a 210lbs person and really they middle should be for a 180lbs person. The bars could balance a 340lbs person in the range and not a 150lbs, ya a little too much focus on supporting heavy guys.
The good new is there is a few ways to fix this:
Swap out the current bars for a different goose neck bar design (the test bars are getting made right now) I think the geometry can work and be just as comfortable as the current ones. Once the new bars are made I’ll send them to the lighter weight pilots that need them, no cost to you guys
Move the motor forward a bit, this can be done as there is room and ESC cooling is not a problem so the motor can be moved closer to the esc. There is still plenty of clearance between the prop and the frame so I would feel comfortable doing that. It is an easy adjustment to be made as just some shorter standoff spacer are needed. Can move it forward 15mm before running into any problems.
The other thing that can be done is getting a longer shackle between the harness and gooseneck bar. If you could imagine allowing the bar to pivot higher up it would make the hang point if attached were it currently is mover back farther to the center of gravity.
I think a solution 2 and 3 can be used in the mean time while I get the new bars made and sent to you for a permanent solution.
Ill make it right, but let me know what you’re thinking you wana try.
