XPWR 40CC applications:
The 40CC is intended for the 78" Extra at around 14+ lbs and the 79" Slick at about 15+ pounds. I have one in a 78" MXS and it's outstanding (you can see it ripping out of hover in the video) but totally excessive. Fun, though. In the Extra it provides power for the kind of big, roaring upline maneuvers the plane wants to do. Fly this one on a 21x10 or 22x10 prop, whatever gets you a little over 4000 watts. For me, that's a 21x10 most days, and 12S 4400mah packs. That gives me 4300 watts for about 300 watts/pound in the MXS. On the Slick I swap back and forth between 12S 4400 and 12S 5000 on a 22x10. This gives about 4500W or, again, close to 300 watts/pound, but propping down to a 21x8 or 21x10 doesn't give up much, and is still about 280 watts/pound, and I do this on hot days. For the 78" MXS and Extra, order our BlazingStar standoff kit. The 40CC with a 22x8 or 22x10 also works well for the lighter class of 50CC airplanes, like the classic 3DHobbyShop 87" Extra 300 SHP. 4500 watts gives about 250 watts per pound on a plane like this. Plenty. Much more than we used to have back on the day when we thought 3000 watts was "killer" on a 50CC plane. Heh. Use a 120 amp ESC minimum on the 40CC.
