RE: World Models Ultimate 40S
My new power level is 1100w/5.5lbs (or 200w/lb) using the AXI 4120/16 with a 6s Lithium pack. I can't remember what the weight was so I'll have to scan the previous posts.
We got some video yesterday showing the Ultimate in some pretty brisk 10-15mph wind. I'll post it later this week. It had plenty of power and didn't really affect the flight. The combination smaller prop on a 6s Lithium pack really makes it nice and fast!
In the end, I feel that I am better off with a maintenance-free direct drive brushless motor.
