i heard end september or mid for 70mm i did not even for know about 80mm motors if they make them at all
i think its going to be same kv as 60mm versions
mikes got 70mm motor kv listed as 2200 and 1600
When I talked to them they are trying to do it asap, but sounds like they are a bit swamped with the demand for their motors. They can't even keep up on the 60mm's. Sounds like it will be at least a couple mos, I would be impressed if they are for sale by end of Oct. The 80mm does sound cool tho.

All Medusa Research motors are rated for 60,000 RPM operation
For the best efficiency, your ESC should be setup with 8º to 15º advance, and a switching rate of 10 to 20kHz.
The above motors have 4 poles."
