Do these RCB kits include the canopies?

I'm new to this thread and have a question. The early CS 10 fan units had 4 stator blades, I purchased a new one and there are many more stator blades. Why is that ? Does it provide more thrust, efficiency , less turbulence ?? I did a simple static thrust test inside an EDF airframe using a 6S battery and a L2855-2100 HK motor and found the early 4 stator blade fan housing provided a bit more thrust. Any answer will be helpful.

I recently changed out a Freewing 6 blade fan for the CS10B V3 in my 70mm Starmax Mig-15 using a Leopard 3400Kv inrunner. With the FW 6 Blade I was pulling 67A and 1030W, with the CSV3 I am getting 85A and 1275W, I am able to fit one heatsink to the Leopard (I had 2 on it in the FW housing but the CSV3 housing is much longer and there is not enough can left to fit 2) but worried these power levels may kill it as it is rated max 80A and 1300W. Has anyone else tried this combination and had it last? The Mig was marginal with the 6B as it is a big model for a 70mm unit so I am really hoping the extra thrust of the 10B will give it a bit more performance.

Can you not cut back some of the housing to make room for the heat sinks? I routinely shorten the 90mm CS shrouds which leaves more room to add heat sinks.

Possibly, hadn't thought of doing that but I will look at it. The fan sounds great and after balancing (incidentally using the method you described on another thread) runs very smooth, I am looking forward to flying it and seeing how the Mig performs compared to the FW6B.

That is a lot of Power (and Amps) for that size of motor! So don't do long WOT runs! hehe
You only need a fraction of that power to fly around 'normal' anyway, so you would fly on more like 500W to 600 W range (700W or so?). So it will do that fine for long term.
It will also be very inefficient at that top end power level. Probably burning 30% (or more) of it as heat!

Understood, I am using a YEP100A ESC so it should survive the increased heat of partial throttle flying OK. The Mig flies OK once it is cleaned up and getting some ram air, so hopefully the 10B will get it off a bit quicker and help it get on the step, then as you say I can throttle back and let it cruise.

Hi everyone. Just wondering if anyone can answer this question.
I'm using the cyclone power 2000kv motors with the 10 blade 70mm change sun fans twinned up in my modded LX mig 29. Currently the mig has a p/w ratio of just over 1:1. Running a 6s 5000mah graphine battery.
each motor is producing-
~71amp
~16750w
Has any one done a test with this motor and the12 blade c/s fans static. Chasing actual results.
Cheers in advance

Your number's seem way on the high side. You must be using higher timing and only measuring the current of one fan running. I'm running the same motors with the 12 blade fans in my LX A10. I think your motors will smoke if left at WOT for any length of time.
Power numbers are here
http://www.rccanada.ca/rccforum/showthread.php?t=311026
Here is a quote of the relevant data. Note one set of numbers for single fan on one battery and numbers for two fans running from one battery.

"After balancing I tested with 6s.

With a strong battery
57amps 1300watts
Settling to 53amps 1200watts
Later in the run
49amps 1050watts

The problem is the motor temps started to rise quickly over 200F at WOT forcing me to reduce power. I think using more than 1000 watts continuous will cause failure pretty soon.

On 5s I think it would run forever but 6s is pushing it.


Got the second CP-CS7012 combo balanced and running with the replacement YEP 80amp ESC. With both fans running off one Gens Ace 5500mah 25C 6S battery the wattmeter showed (total both fans)
2200watts 100amps peak
2000watts 94amps settled
then later after a fair bit of running towards the end of the battery
1900watts 90amps

These numbers kept the motors reasonably cool with some mixed throttle."

Thanks for getting back to me with the numbers.
I will retest the fans/motors checking the timing, amps and watts singularly and as a combo and upload them. Current fans are the 10 blades and drawing 71a singularly so may look at the 12 blades for less amp load. There may be a big differnce in the pitch of the 12 blade giving the lower amp reading. Sounds a bit backward but will give it a go.

Interesting when I recieved both these motors from rc castle, one was showing lower amps/watts and sounded weaker than the other. After testing to locate what was causing the difference, ordered another motor which matched the stronger of the two in amps/watts. Also sounds syncronised now in flight.
Will do some testing today.
Cheers Andy
