I was chosen to review the BR2006 2400kv motors from the Racerstar line, and they arrived last week.

Scroll to the bottom for a quick rundown of my review.

These motors come in a very nice little red box. The box is far from minimalist, with all 6 sides of it covered with info. Unfortunately, the barcode stickers on mine covered up the cool racerstar logo, not sure if this is simply because I'm a tester and they had an extra sticker on it, but it's too bad because I really like the logo on the box. Each box is sealed with a very comforting "QC" sticker. Anyone who's bought things from chinese suppliers in the past knows that QC is usually not their strong suit, especially in this price range.

After dropping absolutely everything as soon as my package of motors arrived (as any RC builder knows is always the case), I got them unboxed.
My initial impressions were quite good, the motors are very attractive, I love the red (I went with a red theme for my build specifically to suit these motors). These motors have 22xx size mounting holes (M3, 16/19mm spacing). I was really hoping they would, because I'm really not a fan of the 1806 mounting holes. There's no spot for a countersunk, 2mm screw anywhere on a quad build, finding screws is a nightmare, and mounting them is a challenge since the frames that do include 18xx holes are 45 degrees offset, and put the motor wires in a weird place. The bolts it comes with are not the standard button-...Continue Reading

I got my hands on a really nice power supply. I now have a server supply (12V 41A) and this one which does a few amps at 3v3, 10A at 5V, 19A at 12V, and 0.1A at -12V.
So at first I just converted it from ATX to a standard bench supply with 5.5mm connectors on each end and started making adapters, one for an RX to be plugged into 5V, and a deans plug that I can use for testing so I don't always have to find a charged battery just to power something up. I also added 5.5mm connectors on my charger so I could power them off of this and I plan on re purposing the server supply (suggestions?).
After that, I realized it was taking up the remaining 1/25th of my workbench that wasn't already covered in stuff, so I mounted it underneath the table and had the connectors on a little dev-board connected to all of the wires. Once again, a pain. Now all the wires have to reach around the edge, and to the connectors underneath. So I pulled the wires on the PCB and hooked them up directly to the connectors with some more wires to add length. I then drilled holes in my workbench (an old card table) for the LED (power on), and one for each terminal. The holes were 1/4" which worked out to less than 5.5mm so I had to hammer them in for a nice, snug fit. The downside to this was that I had to make my final solders under the table, not as fun as it sounds.
This is how it looks now. I can't figure out how to mount the switch since I can't really easily cut a rectangle in 1/2" particle board, so any suggestions are welcome there.
