Good value motor

Jan 15, 2021

Only 5 flights, but no problems yet. Connected to a 6s pack via a Castle Creations 100A ESC and with APC "E" props recorded the following:- 11x8 20A 490W 12x8 27A 655W 13x8 33A 790W 13x10 44A 1030W 14x10 50A 1177W
Hope this is useful. I personally wouldn't run a motor of this size at over 50A.

Very good engine used with 80A ESC, 15x8 propeller and 3000 Mah 6s lipo. Over 1100w of power.
On my extra 60in it drags in unlimited vertical.
I recommend buying, quality workmanship and good looks.

Turnigy SK3 series motor

Aug 14, 2019

These are the top of the line motors, if you can find better, buy it. I have several of the SK3 series motors and have yet to have one even hiccup. They run beautifully, are well balanced, perfect draw on the ESC'S and LiPo's. Best product for the best price.

Looks a nice motor, bought to fit the HK Tomhawk propjet with 13x8 prop 6S 4000 Lipo gives just over 1:1 power weight ratio at 3200g. Flight times of around 10-12plus mins depending on how hard your flying. Could do with some form of holding method on the propshaft to help when tightening the prop nut as theres nothing to hold when a cowl cover it
