Thanks for the quick response, so I'll be using this one http://hobbyking.com/hobbyking/store/uh_viewItem.asp ?idproduct=35024 Turnigy T600 1400kv, I have one doubt though, in the specifications there is this text Turns: 8T, what this exactly means? it has to use a 8T pinion or should a 11T pinion will work fine, I was thinking on this product for it http://hobbyking.com/hobbyking/store/uh_viewItem.asp ?idproduct=38989 "Hard One" 1.0M 11T for 6mm shaft, but as I'm really newbie with the rc heli stuff I'm not really sure if this will work or what implications will a different pinion diameter will cause to my flying.
I have this on my 500 and this motor has lots of torque and power. but I would not put this on a 550 size heli. you want a 600 size motor for a 550. hope this helps
No I use this motor in my 500 Heli,But I do have a 24" Air boat and I use a S3674 2370kv in it on 3s with a 10x6 prop with a watercooling jacket on the motor with a Turnigy 120 amp esc,and it works very well,almost takes off(its fast)Hope this helps.JK.
Can anyone confirm this motor has 14 poles? If that is the case, you will need to use a super fast ESC for anything more than 5s use. Many ESC's top out at 240,000rpm for a 2 pole motor, which would be only 34,300rpm for a 14 pole motor. On 6s, this motor might try to run at up to 38,000rpm, which could be enough to lose sync with many ESC's.
I own one of these and recently took it apart. It has 6 poles, not 14 - this was a big surprise to me and caused issues when I entered 14 in my governor settings. Entered 6 now and all is well.
Hope this helps!
I have the timing at 30 degrees and 8KHz Frequency on my 500.Works great.Check your esc and motor for heat after first run.Hope this helps.JK.

Well, if I were to describe this motor in 2 words they would be POWER and TORQUE.
This motor is a monster, not only in torque but keeping those RPM high. This replaced a $25 'off brand' 1600kv motor which was installed on my 500. I have two stunt modes, 70pcnt and 100pcnt flat - I can honestly say that the 100pcnt flat on the 'off brand' motor was equivalent to the 70pcnt on the Turnigy SK3, same pinion, same lipo. At the field I really tried to bog this motor but it just wouldn't, the magnets are extremely strong. It was about twice the width and 1.5x the weight of the original motor, really nice and beefy. I would give this motor an 11/10 and given the choice would choose it rather than a comparable Scorpion. It has 0 slop and the bearings / windings are quality. I will be buying an SK3 700 class motor for my Miniature Aircraft Ion x2.
