Hobbyking Mini Quadcopter Frame with Motors (550mm)
The HobbyKing Mini Quadcopter Frame is an inexpensive platform for quadcopter experimentation. Built from light weight yet rigid plywood offering a great combination of weight reduction and strength. Shipped in flat pack form to save on postage costs, and with our full line of available quad electronics such as quadcopter control board, ESC & batteries, it has never been easier or more affordable to get a quad in the air!
The included motors are manufactured from a Polyamide material, making them extremely lightweight, durable and inexpensive. The built-in prop savers will help protect your propellers in the event of unplanned "landings". All you will require is 4 x 12amp ESCs, a 1500mAh~2200mAh 7.4v 2S Lipoly battery, 4 x 7035 Props (2 std & 2 counter rotating) a 4ch receiver and the all important HobbyKing Quad control board.
I have this kit. I am fairly certain the SKU number for these motors are PM19M-2400. These are 2200KV motors. They look the same, but PM19S-2800s are 2800KV and would not work in combination with the PM19M-2400.
If all four motors are the same you should be okay. Those motors have a little less power the recommended motors, and with the higher 2800KV they might be a little less efficient, but it will still be plenty of power for this quad frame.
Interesting question. From the specs on this motor the maximums are:
7035 8.0v 8.6A 68.8W 12060rpm 352g
You should be within the limits of a 12a ESC. I use 8040 props with the 2200KV motors, 12A ESCs and 1200 mAh battery. I get a little over 7 minutes of flight time without any apparent problems. I would be curious to hear what you get for flight times.
You need to buy prop saver. I just used a string to tie it on the to the screws on the side of the motor. And the recommended prop won't work. You need counter clockwise props as well. Search for "7x3.5 prop" You will see an item that says clockwise and counter rotating props. Hope this helps.
Is there any way to remagnetize the tiny magnets?
I'm not sure if there is a wiring problem like the other reviewer mentioned. But I can be sure that 3 of my 4 motors failed. Now they run at 1/2 speed compared to the 4th good motor. The electric power is instead used to make them hot. When I took one apart I am certain 3 of the 10 tiny magnets are demagnetized completely. The heat is a symptom of the degmagnetized motor. But it could also be a cause of it? Not sure which came first. Certainly the motor will not run fast with 3 bad magnets. This happened within 30 days of my purchase.
HobbyKing will you help me?
The 7x3.5 counter rotating props for this kit are pretty much unavailable. The ones HK sells are back order and are lousy acording to the reviews. Does any one know how to make this thing work with conventional props?
Here is the MOTOR TEST DATA
7035 7.4V 8.1A 59.9W 11460RPM 324G
7035 8.0V 8.6A 68.8W 12060RPM 352G
7035 8.4V 9.1A 76.4W 12360RPM 376G
so 4 motors can pull 1408grams. in which TOTAL weight of electronics, motors frame and battery is around 450 to 550grams.
so remaining payload weight can take is around 800grams. to save flight u can payload around 400grams.
Es un buen producto para iniciarse en el mundo de los QuadCopter.
Fácil de montar y reparar.
Bien ajustado y calibrado vuela con facilidad.
No es muy resistente, intenten evitar darle golpes.
Siempre que sea posible volar sin viento y sobre terreno blando. Por ejemplo cesped, grava o arena de playa.
Mucho cuidado con el viento
Recomiendo HobbyKing Multi-Rotor Control Board V3.0 con Firmware de KK www.link configuración XCopter es más www.link
Not the best quality, but a quick and cheap way to get you in the air. Check your motors, one of mine rubbed against the bell.

If you are serious about getting into quads give this one a miss - it is not worth the money.
I put together this one with the stock motors. In one word these motors are "BAD" . Of the four motors three are badly out of balance and being to wobble badly at about half throttle i.e. using the recommended 7x3.5 props. 'And yes I took time and effort to balance each of the fours props. Even with the props removed when the the motors are spun up, the frame beings to hum and vibrate badly (it even starts wandering when placed on a smooth top table).
Further, the rigidity of the frame is poor. If one isn't careful in balancing the motor / prop combination the frame can get into severe vibration (resonance) and the controller board (I used the HK Quad controller board) gyro outputs become badly corrupted due to this i.e. the controller board becomes pretty useless once resonance sets in.
I used the HK SS 15-18 Amp ESCs along with a Trunigy Nano-tech 1800 mAH 2 cell battery and the HK quad controller board (Version 1).
I could do a few flights but gave up as it was very difficult to control the quad - basically BAD motors.
BTW, I also purchased the Turnigy micro quad kit with PLUSH 6 Amps ESCs, 2 cell 850 mAH nano-tech battery, 5x3 props and with the same HK Quad controller board (Ver 1) - the set up flew like a breeze.
I have ordered the Talon frame and 28 size motors - will w
The frame is a bit fragile but it is a good starting point for a quad and it is also very, very light. I glued mine with CA. It can be sprayed with varnish in order to stiffen the wood. 2 of 4 motors came unusable but the stator can be filed just a little bit in order to work out. Cannot comment about balance yet... I will try 8x4 props as well, because the 7x3.5 ones from hobbyking just ain't good enough. I wouldn't recommend the kit to somebody who expects it to work just right-of-the-box. 3 stars for the price.

Shame, shame, shame on you HK. Just because I didn't give a positive review, you remove my review all together? Also, customer service is apart of the buying experience and should be including in a review.
As for the review, 3 of the 4 motors I received were bad, I've read it's common that some of the motors show up and the can will rub. Be forewarned, if you receive a defective motor, or 3, it's a very timely delay and was told via Live Support you'd be better off taking a refund and ordering a new kit. :/
I say this not to flame HK but to inform others that if something shows up defective that they can expect a lengthily delay.
