I recently crashed my 450 Pro and some how stock 450M motor got damaged. I do like the power of he 450M but am now looking to upgrade. I am trying to decide on which Scorpion motor to get. Either the HK-2221-6 or -8. What should I get? Using a 3S set up.



Why buy?? when you can borrow and no return

I have both the -6 and the -8, the -6 is a beast and awesome for hard 3D, the -8 is more comparable to the 450M motor.

-8 is fine for us mere mortal pilots! The -6 is 4400KV more than the average Joe needs!

i say the scorpion 8 on 4cell. ive been flying this setup the past few weeks and i havent flown a 3cell battery since, im running the 8 with 12tooth pinion governd at 3300. this combo is easily pulling 600plus wats in my flights ive pulled a maximum of 780 in one flight. normaly though it oulls 600-690 in long climbouts and maintains the head speed easily.

scorpion 8 on 4cell rocks. im gov at 3300 and i can run gov to 3500 with the 12tooth pinion

i dont do any 3d but if im ever do ill have power on tap to spare

the scorpion 6 on 3cell would also be cool with a govenor to see its full potential. i cant belive how much flying the ice governor has changed my heli, very smooth now and tail holds much tighter
