Micro P51 Brushless

Here's what you need to upgrade to brushless. The original mustang BNF or RTF. Foam-Safe glue. I got a 4.3 gram C10 ultra micro brushless motor. HK XP3A micro esc (.7g 1 gram speed controller). In the pic you can see I have an extra spinner and prop, extra lipo's and micro wiring harness (not compatible). I got the wiring harness to make it easier to connect the esc to the onboard 6 channel receiver (DSM2 Ultra Micro 6ch Receiver with micro servo's).

 

You need to cut the decal along the crease to open the fuselage.

What's inside the P51. You can see the micro receiver with servo's built in. I unplugged the motor wires from the left side of the receiver chip. It is a 2 pole plug for the stock brushed motor. The receiver is upgradable to brushless with 3 pole connector built in.

 

I got some foam safe glue to install the new motor.
 

You can see the sizes compared to the stock motor. The brushless upgrade adds more power, and very little extra weight to the aircraft.


I am currently soldering and installing the new motor!! Will update as soon as the plane is completed (date friday july 08 2011) Expected to finish the model within the next day or two, check back soon!

Here is a Diagram of how to connect the 1 gram ESC to the DSM2 6 channel micro receiver. Just the signal needs to be connected between ESC and DSM2. The Rx just needs to be changed to "brushless mode" (see below).

To convert your DSM2 Rx to "brushless mode" (included 4ch controller setup) You just need to hold your Throttle all the way UP with controller ON while holding LEFT RUDDER. Plug in your receiver while holding this and wait for the LED to BLINK 3 times. Then turn them off and your ready to fly with brushless setup.
note: the instruction manual for DSM2 has the signal and NEGATIVE - terminals backwards. Connect as shown above for proper signal output. 

 

I have taken the parts included with esc, and soldered the motor wires into the small slots with some precise handling. I added a small amount of solder onto the wires, then heated up the metal melting each one in.


I cut and soldered the battery wire's back together with an additional wire for Pos+ and Neg- to connect to the new speed controller.


Mounting the new Brushless C10 motor to the plane. I cut away carefully into the "firewall" like foam inside the fuse. glued the motor on with the included fiberglass mounting plate included with motor. I added some reinforcing foam behind the "firewall".


I added the esc to the motor that is now installed. Now just connecting everything.


Now it is all connected. If you need to find metal wire to solder your wiring to... try guitar string. It works perfect to connect your terminals together.

 

Now just tape the fuselage back together with some clear tape and its ready to test your esc and motor. Follow instructions with the esc after switching the Rx to "brushless mode", I found out the wires in the harness came broken. Once I re-soldered the signal and battery terminals it all works perfectly. 

Use the manuals to help get the conversion working properly

Ready to FLY!
