Need Help with a Lehner 1940 4 wind motor

[david hall]

Tyler the 4S setup weighs in at almost 4 lbs. I shaped a piece of foam (green). and laminated it with 1/32 ply. I then machined pockets for motor / ESC and battery. If I ever hit anything it will be toast.

Damn I have to try some lifting props, that graph looks about the same as my JAE's were on 4s with 2700KV Neu1415 and a detongued X438, yours must be riding on just the very tips to have the same amp draw despite more pitch, more diameter and an extra 15-20000rpm
