I put this motor in a 450 that I'm doing a 480 stretch on, just a seV2 clone. I only have 325mm blades on it at the moment, running 4s with an 11 tooth pinion. The performance is great so far, punchouts are better without any bogging of the motor. everything comes down cool. I will be putting on 360mm blades soon as I receive them, and can't wait to see how it does. If I was sticking with 325's, I would probably up it to a 12t pinion, but even the 11t on 4s is alot better than a 3s setup. The only gripe so far is no flat spot for the pinion set screw. I tried at first to not grind a flat spot, but ended up auto rotating down after a few flights when the pinion slipped. A dremel tool fixed that quickly though. After seeing the performance, I think I'm gonna upgrade another one of my 450's to 4s, and try a 12t pinion on the 325mm blades. (For your first flight, I would recommend adding in some expo, as the extra headspeed made mine quite responsive and could have easily crashed on first flight)great motor for 450 pro, i used a dremel to grind a flat spot on the shaft so i had something for the screw to grip on but apart from that just bolt it in and fly awayThis is a small outrunner with good power for helicpters.. I have it installed in my micro cat 650mm speedboat on 4S Lihtium-Mangam 4000mah 15C. For this boat and a 38mm two blade prop too much. The motor gets very hot without watercooling and full throttle. I use again my Leopard Inrunner Motor on 3S 8000mah 15C Lithium-Mangam Battery.
For this money very good 6 pol outrunner.Hochwertiger und sauber ausgelegter Motor, 40A sind Kurzzeitbetrieb, MF Wicklung ist soweit OK, Umwickeln auf Einzeldraht lohnt mit Sicherheit, als Regler habe ich YEP 40 und 60 ausprobiert- fr berwiegenden Vollgasbetrieb geht der kleine, fr Teillast ist der groe angemessen. Ich verende ihn im Direktantrieb mit Aeronaut 8x5,8x6,8x7 an 2s fr einen 1,5 m SoftlinerI run this motor on a Mini Outboad unit on 3S with 33mm prop. Super performance, high torque. Performs the same as the stock 3000KV 2218 outrunner but with very moderate amp draw, between 25-30 amps. Original standard motor was 35-40 amps. Well build, no problem when it gets wet. With motormount cooling on the outboard it stay's absolutely cold. Wil certainly buy more!Just put this motor on the e-razor 450 not really knowing what to expect because I am running 3S and 12t pinion. There is a reason this motor is rated 4-5S, it is HIGH PERFORMANCE.
I finally got this motor dialed in at 3S, I had to go low on the esc timing and cut the throttle curve down and it is working ok with plenty of power and speed more than the stock motor.
It was cutting out without reducing the throttle and timing and had crazy headspeed!
I am saving up for the 4S batteries, I can only imagine what this thing could do on 4 or 5S like it is suppose to have!
I feel like it was well worth the low price.Just manage to try out with my PA Quantum 45A Esc & 4S 25C LiPo.
Fly on 335mm Blade for about 1 minute of hover then i found that the motor was really hot. is there anything that i should know why this is happening?A nice high-gloss finish. Produce power well with 45A YEP ESC in a 4S setup. I use it in my 450Pro V2.
Does not heat up too much even in a harder flying.
Cons: No flat spot in shaft for locking screw. Comes without mounting screws.
