GH2820-04 Outrunner Brushless Motor – Firewall Mount

Today Scott and Basil decided to install this motor on the Multiplex Dogfighter.  Not having our Amp meter, we took a educated guess for the prop size.  We started with an APC 7 x 6 and had good results.  But of course it was not the 100mph we were looking for.  So we took a GraysonGold 4S pack and shoved into the battery hatch.  There was not much room, but it did fit.  Gave it another toss on the 4S lipo and we were able to reach 100mph.

On landing we check out the motor and springily the motor was cool to the touch.  It looks like this is a real economical winner.  The Grasyon Hobby 2820-04 with a 7×6 gave us the best flying results.  Not the fastest times, but the most torque with the most flying time.

 

Great Motor for the Multiplex Dogfighter. The Grayson Hobby GH2820-04 can put your dogfighter at speeds near 90mph!

  1. I need to know what would be a good motor combo to up grade my harbor freight p51d Mustang I need more power?

    1. Im not sure the size of the HarborFreight P51, but I hear most are using the MicroJet V3 with 20Amp ESC. The battery of choice is the GraysonBlue 1600 mAh 11.1v (3S)

  2. Hey! I just would like to give an enormous thumbs up for the nice info you’ve here on this post. I can be coming back to your blog for extra soon.

  3. To understand the advantages of the brushless motor, a basic understanding of the brushed motor is required. In a brushed motor, an electromagnet is mounted on a spinning arm, called an armature or rotor. The armature sits between two magnets set in a horseshoe configuration, collectively called the stator. When power is fed to the electromagnet, the arm moves, aligning the north and south poles of the electromagnet with the opposing poles of the stator.*
