Alkaline,

Unless you go with the factory-recommended setup, electrics aren't as simple as picking the first thing off the catalog page. You've got to make sure everything works together first.

1. BrushLESS motors require brushLESS speed controllers, and each motor requires its own separate controller. You can't use a regular brushed speed controller with a brushLESS motor, let alone two. If you want to use your 22 Amp speed controller, you must stick with the stock brushed motors.

2. You have to be careful when selecting a LiPoly battery. It has to be able to handle the Amps being drawn by the motors, and it has to be the correct voltage. A 3-cell LiPoly's voltage is too high for the stock 300 motors; they will burn out quickly. You need a 2-cell LiPoly. As for the current, it needs to be able to withstand at least 16 Amps. As I said before, a 2S ThunderPower 2100 should be perfect for the A-10 with the 300 motors, whether you stick with the stock motors or go brushless.

I would not buy a LiPoly from someone off Ebay unless it's a known brand. Some people are selling substandard, useless LiPolys on Ebay, and you're probably just throwing your money away.

My suspicion is that when you tally up the cost of going brushless, you'll want to stick with the stock 300 motors. It's going to be around $250 by the time you get both Himaxx motors and both speed controllers.

Flypaper2,

The EDF50 is the one with the thin IPS motor. A Himaxx 2025-4200 won't fit without major modifications. You're probably thinking of the EDF55, for which it should be a direct bolt-in. The 20XX Himaxx motors have the same bolt pattern as the 280 & 300 motors. If you've got the motors, they'll work fine. I only recommended the 2015-4100 because it's lighter, has a Kv that's not much different from a 300, and will handle the power.
