Hey gang, I posted a thread over in the Mini & Micro RC subforum - I really want to build up a BRUSHED Mini-Z to run in 2wd Mod - and I think I've talked myself into it.
I want to build a MR-03 (or maybe PN 2.5w-based) Mini-Z to run in 2wd Mod, but I want to use a brushed motor. I love the sound and driving feel of brushed motors, and I think it would be fun to put on my engineering hat and try to do something a little unconventional - run in 2wd Mod without a chassis car. I'm certain that I won't be able to get the car to handle as well as the cars of the people that actually run in 2wd Mod, but it'll be fun to see the looks on their faces when I beat 'em on the back straight - even if I can't hang anywhere else!
Here's my approach: Starting with an MR-03, I want to upgrade the electronics so that I can run a lower-turn brushed motor on 2s without blowing the MR-03 board. Having a nicer receiver with better responsiveness and higher resolution will help, too.
Because I love them, I might build it up as a PN 2.5w - but with the general idea that it's definitely not a chassis car - just a brick of plastic with a built-in servo and a giant motor.
I already have:
I was going to cut up the existing MR-03 board, or buy another one - but they're $40, and I don't like wasting usable parts or cutting things up if I don't have to - so I found the servo motor and the potentiometer at A-Main, shipped, for under half the cost of a new MR-03 board. I've also ordered some 30-gauge wire (should be right, I think?) to hook everything up.
Since I have several other projects that are WIP, I'm in no awful hurry to get this built, so I didn't get rush shipping on the servo motor or potentiometer. They should be here next week; if they arrive before I leave for a week to travel with my wife, I'll try to solder everything up - or maybe, I'll just desolder the servo motor and potentiometer from the MR-03 board that I already have, secure in the knowledge that I have replacements on the way; depends on how impatient I'm feeling, and how much free time I have.
At any rate - I'll keep you all posted! I've never done a build thread before, but I can already tell that this is going to be a lot of fun!

I already have:
- A donor MR-03
- A FlySky micro receiver
- A 2s-capable brushed ESC
- A big brushed motor (PN 43t that's probably going to blow the FETs on my MR-03 board any day now)
- A way to use the FlySky receiver with the built-in five-wire servo
- A PN 2.5w (probably)
- A bigger brushed motor (PN makes a 31t!)
