hi,after reception of the motor,the included instructions shows differents informations about the power and the kv of it D2836-8...7.4-11.1V...950KV...MAX POWER 268W and this motor can't be installed in an aeroplane whith a front prop whithout hard modification(reverse motor shaft) i think you should informing customers about that
THANK YOU TO PURCHASe FOR EXPLAINATIONS
Do you guys think that 4 of these motors would generate enough power to lift REPTILE 500 frame (link: http://www.hobbyking.com/hobbyking/store/__40640__RE PTILE500_V3_Quad_Copter_Frame_With_Crab_Landing_Gear _White_Red_.html?strSearch=reptile%20500 )
Hi oguz..., 4 of these should have more than enough power for that quad. You'll get up to approx. 1kg of thrust from each motor on a 3S LiPo, so there's lots of power on demand. Just be aware that the 18A max current spec shown above is incorrect. These motors draw approx. 24A-25A at full throttle with a 10x4.7 prop on a 3S, so you will need to size your ESCs and LiPo(s) accordingly. Cheers, EA!

Hi RC2211, I'm assuming you'll be running the motor on 3S LiPos, so my advice is based on that. It'll turn a 11x5 okay, especially if it's an APC style prop, but it will be just a little bit over-propped so be careful to watch for any signs of overheating. I run 10x4.7SF props on this motor for 3D flying and have never had a problem. Thrust is just over 1kg and the motor is barely warm after 6-8 minutes of hard flying. You might get as much as 1.1kg-1.2kg of thrust with the larger prop, but that's just based on educated guess, not measurements. Cheers, EA!
Thanks! I was actually planning to put it on a quad. Sounds like 10x4.7 will be sufficient for my needs (total AUW is about 1.3 kg, so plenty of power). What I am worried about is max amps. It seems like on that prop these will pull more then 18A on 3s. My Lipos can only take about 80-85A continuous.
Hi RC2211, Thanks for the credit. Sorry, I got focused on the prop part of your question and forgot to address the ESC/amps part of it. The 18A max current shown in the specs is rubbish. HK must have cut/pasted the data from some other motor and forgot to change the max amps spec. The motor will draw approx. 24A-25A at full throttle with a 3S and 10x4.7SF set-up to get 1kg-1.1kg of thrust. If you're only lifting 1.3kg with 4X motors you can back way off on the prop to something smaller (a 9x4?) and still have plenty of lift without exceeding 20A/motor at full throttle. Your LiPo should be okay since you'll rarely be pushing full throttle for more than a few seconds. My guess is you'll be pulling approx. 30A-32A total for level flight/ hovering a 1.3kg quad with these motors. Cheers, EA!
