muy descontento con este motor,coge demasiadas revoluciones no creo que sea de 1000kv ,y no tiene nada de fuerza ,le metes un poco de paso i ya cae de vueltas no lo recomiendo

If you need a varible pitch motor, take a look on this video. You can easily mount one with a DT750.

plse how to mount this motor becoz what i see in photo its make me really confuse if its Outrunners motor prop shuld be on front be i can see in this photo mounting shift near to prop plse some one help me with photo or describe me briefly becoz i m going to to build my first 4d plane thnaks

The motor is on the back. They're expecting you to mount the front to front firewall, then have the motor and servo to control pitch behind the firewall. Some motors you can reverse the shaft to the other side. Not sure that would be a good idea with this type. With all the weird loading, you want the prop as close as possible to the bearing, otherwise it will have huge leverages against it.

could i put this on a quadcopter to give it inverted capabilities???
 KaosKane 1728 points
if u had 4 then yes but the quad prog board may have a problem
 Theunsie 375 points
Hopefully some one smart will program the kk2.1 to have inverted capabilities but in the mean time look at Curtis Mr Youngblood's site for a capable board

Would you mix in pitch w/throttle or would you want it controlled on another channel? Can someone explain how guy's have setup and how you would use it during flight. What are the positives/negitives of having pitch control other than it's pretty cool and scale. I imagine it would be easy to overcurrent your esc if you aren't careful. Any tips would be great.

Appears to be a tiny motor. Any plans on a larger var pitch set?

either one!would prefer another channel though.

i would set a fixed throttle at maybe 80% and run variable pitch,that way you don't run the risk of over revving or drawing to much from your ESC, just like how a heli runs

It is released very serious if a person reaches WHAT can happen is unpredictable, the a Hobby King has no spare parts from the parts vaiable pitch.
I give up comparing this engine is too risky to drop a piece.

spare blades in stock now :}

The majority of problems seem to be most people don't understand how to run a variable pitch propeller at all. Read the stuff in the FAA Pilot License manual, and learn how a constant speed propeller is supposed to be used. You keep it at higher RPM, as someone mentioned around 80% might be reasonable. When the airspeed is low, you keep the pitch shallow, giving the blades lots of leverage against the air. As airspeed increases, you can increase the pitch to adjust for the motion, and give the propeller bite over the forward speed. If you have this at RPM while the airspeed is low and dump high or reverse pitch into it, you are putting many many times the stress it can be designed for into it. You don't instantly adjust the pitch, you do it over at least a small amount of time, to allow time for the RPM to do the work. It is very similar to a Dremel tool. If you use pressure, and lug the motor to do the work, you can easily ruin the Dremel or bit in no time. Instead if you use light pressure, and allow the RPM to do the work over time, it works better and will last. Realize too, the maximum specs of this. It's a 10" prop on this listing, and 100W motor. What 10" normal prop would draw 100W on a smaller motor like this? Maybe a 10x04? You shouldn't exceed whatever it is, until you're unloading some in the air from forward speed. Most people are probably setting these up with way too much maximum pitch in the first place, far beyond what it can actually do. Do your math. 10" prop goes 31.42" around for a turn. So a 10x10 prop would have a rise over run of 10/31.42. Rise/run of 10/10 would be 45 degrees, 10/31.42 is less than 1/3rd of that. So about 15 degrees. And that's for a 10x10 prop, way more than the 10x04 or 10x06 maximum throw you should have on this motor, so about 8 degrees. Bet most people are setting this up for 45 degrees pitch, far, far beyond what it should be. That's fine for blowing air at low RPM when at low throttle, but it's a ridiculous pitch at running RPM. Do the math and you'll realize almost no one is going to be setting these up with as shallow throw as needed. Thus the problems are often user induced, from not doing the homework and having way too much pitch throw. Shallow, light passes, and let the RPM do the work with lower load on the motor and the tool/prop. Exactly like a Dremel tool.. Note that's near the edge, so maybe 50% or more more in degrees, for the average closer in. But still won't be 45%, which a lot probably have it set to or close.

Ah, 45 degrees not percent at the end. Also HK removes formatting so looks crammed..

1 thumbs up!
I bought 5 sets 10 days ago: I had severals problems. It is very feeble. During the first test I risked to kill myself because the screws that should secure the propellers to the main motor shaft bent. The motor barrel exploded and one of the props hit a plastic box ten meters away, disrupting it. Choose another kit...

motor un poco chico para el paso a que lo somete, con un motor con mas potencia seria el elemento ideal para el 4D.
