Designed to provide reliable and clean power for 3D parkflyers. This brushlessoutrunner will provide more power and with its high efficiency, long run times. A quality motor, built specifically for planes designed to fly with a 250 watts brushlessoutrunner.
Spec. Battery: 2~3 Cell /7.4~11.1V RPM: 850kv Max current: 28A No load current: 11V/0.9A Internal resistance: 0.09 ohm Weight: 80g (not including connectors) Diameter of shaft: 4mm Dimensions: 34.7x36.9mm
It won't fit the shaft needs to be quite a bit linger to be able to clear the cowl. It might have the power of the ******** motor BUT will not fit any of the ******** park fliers like the T28. You would have to created your own firewall and motor mount.
Hi, I would like to creat a quadcopter which would weigh 3kg or 3,5kg (depending of the number of batteries). Would it be ok with these motors?
Can I count on 4kg/4,5kg thrust max with 11x4.7 props? And 80A with 4 motors ?
If not, I would move to an octocopter coaxial, what would be an adequate motor? (~50g each, max thrust with 8motors ~4/5Kg). I can't find exactly what I'm looking for :/
Thanks a lot!
your thrust should be at least 2 times the all up weight of your copter. So for 3-3,5 kg you should have at least 6-7kg of thrust.
I use these on my Y6 with auw 2,8kg. Currently still experimenting with props. The SF Props are so soft, I do not really trust them. Y6 flies already very well with 10x4,7, so thrust should be easy 1kg each. However, I am still trying to find the optimum prop, currently it looks like its going to be a 11x5.5 APC one these are back in stock.
NO It won't fit the shaft needs to be quite a bit linger to be able to clear the cowl. It might have the power of the ******** 480 motor BUT will not fit any of the ******** park fliers like the T28. You would have to created your own firewall and motor mount.
i have a balsa plane with 4' wingspan, weighing in at around a pound (no motor) would this be the correct motor to use? someone at my local club recommended this for said plane, but i want to make sure. also, what amperage of esc should i use?http://www.hobbyking.com/hobbyking/store/images/ em_rolleyes.gifhttp://www.hobbyking.com/hobbyking/st ore/images/em_party.gifhttp://www.hobbyking.com/hobb yking/store/images/em_rolleyes.gifhttp://www.hobbyki ng.com/hobbyking/store/images/em_cry.gifhttp://www.h obbyking.com/hobbyking/store/images/em_cool.gif
This would be a great motor for that size of a plane. I've currently got one of these going in a similar sized plane, may even be a little bigger. This is the controller i ended up going with Hobbyking SS Series 40-50A ESC
I picked it mostly because of stock, but any 40amp or greater would be good.
You don't understand: Compare the 850kV version WITH the 1320kV version. It's basic physics !!! Either 850kV will also work w/ 4-cell or if it will burn, then the 1320kV Version can not able to bear 3-cell operation. Otherwise, something must be wrong ! The manufacturer/developper will understand my question and should answer this miss match.
I think the 3s limit has to do with the size of wire used in the windings* it is too thin to stand up to 4s voltage at load. The winding count determines the RPM/v relationship, and the size of the wire used determines the max voltage it can handle.
-> francois, scott if you lay-out a motor, you define max speed and max torque by electro-mechanical parameters, resulting in max power. The winding is then the way to adapt at which voltage you get this output. Performance is then near same ! Higher voltage but less current w/ the higher kV-version. (It's easy to understand, if you look on the equations.)
-> drr24 - 'Higher voltage but less current w/ the higher kV-version.' I think it's the opposite. With a higher kv you need less voltage to get the same rpm. Maybe it's not what you are talking about ?
again for better understanding: limits are SPEED and TEMPERATURE by power loss. speed limit is NOT achieved w/ 4cells, as is lower than the 1320kV-version w/ 3cells. Power loss is dependant on your load - e.g. if you block the motor you'll be beyond limits even w/ 3cells - so be cautious w/ load, i.e. current (and cooling) !
The gauge of the wire is smaller for lower kv motors, so that you can get more windings in the same space. Smaller wire means, it won't handle the higher voltage. If the spindle size of the 1320kv and the 850kv are the same, then they are using thinner wire. Then if the manufacturer says, 3s, you better stick with 3s, otherwise you risk burning out the motor.
that's not correct ! Smaller wire can handle less voltage of ohmic power loss - don't mix that up with voltage of megnetic induction caused by speed ! If you consider the ohmic power loss in the windings by the given current limit, the voltage is irrelevant.
Have used this motor in applications where I would have used an Eflite 480. This motor is every bit as good. IT performed flawlessly! Great motor, as all the easy match motors seem to be. I wouldn't hesitate to use any of them.

Very good motor, good winding, fine laminations ; I replaced the original motor of my HK EPP Fox by this one and it has become a new plane for the same amp hunger. Climb angle 45° or more for the same weight. Will use more of the same motor "family" PierreW
I have four of them in my MultiWii quadrocopter. 3S 2200mAh 30-40C, 4x Plush 25A, 9x5 props. 40Amps peak for all 4 engines = 10A each. Fast throttle response, they work really good. You'd have to buy better prop adapters, as those included are not well balanced - but for those, who want just to fly (no camera) they'll be OK. Power is great, performance is great - definetly 5 stars.
