ya, that 2200 NEU MM motor is crazy!
as for the over rated 6hp, well.....

NEU rates this motor at a constant 1500watts and peaks at 2500watts.
I have seen someone with a data logger showing a half second peak at 3800watts! he over geared it on 6s to get that peak power and thats just over 5hp! nuts power
2hp contsant power is crazy, no need to get to full rpm to make that power with brushless motors.. the power is right now!

My SV27 FE with a CF48 prop possibly puts out 800 peak watts and got me 41.3mph today.. so your setup is going to be crazy fast!
