Xk Mini P-40 Warhawk (A220) - Brushless / DSMX Mod

Here is my progress on converting my model A220 Warhawk to DSMX protocol and fit it with brushless power. The stock receiver was removed and an Eflite receiver installed. The receiver is the AS6410L from the UMX PT-17 Stearman. I tried replacing the 10mm brushed motor with a brushless 10mm inrunner first since it was the easiest mod. But that motor is intended for 2S power use and did not deliver as much as I had hoped for with a 1S LiPo. During the first test flight the plane was quick, but due to the extra weight of the brushless inrunner motor plus 2 grams of ballast I added to the tail cone it felt under-powered and wanted more speed/lift. I will save the inrunner motor for the bigger P-47 and run it off 2S in that plane where it should prove ideal. So I moved on to plan B and fitted the P-40 with a TALON 1204 6250 Kv outrunner operating in direct-drive mode. This install process was more involved and required cutting and removing some foam from the nose to fit the 3mm thick plywood motor mount/firewall. Carving the pocket 10mm deep was ideal to fit my motor and prop hub choice. The process involved removing the red plastic ring screw base from the nose of the fuselage. It's not held in very well. Once I had it out I trimmed it's inner diameter with a dremel until it fit snugly around the motor housing. This let me use it as a centering fixture to keep the motor perfectly aligned with the cowl as the 5-minute epoxy securing the wood motor mount cured. I just slid the ring into place and did not glue it yet The next day I pried the red plastic ring off again and trimmed it a mm or two more on the inside to clear the spinning motor housing proper. I also had to shave a bit off the four tabs on the back of the red ring so that they would not bottom out against the wood motor mount when the ring was re-inserted. I still have yet to test-fly the direct-drive configuration, but it looks promising. The gear reduction system sounded fast, but that was mainly the motor spinning much faster that the geared-down propeller. With the direct drive set-up all you hear is prop noise as it spins as fast as the motor itself, and it sounds quite nice. The plane shed several grams in removing ballast and a heavier motor in the conversion to direct drive, so performance should improve by that factor alone. Looking forward to the next test flight. So fingers crossed and HAPPY FLYING!
