Finally finished converting a Kyosho ST-RR to brushless.

Thanks very much to Shark413 for his help, as well as another user who I can't find the name of right now.

At the moment its running:

4s2p A123 batts
Fegaio 8XL 2000kv motor
Monster Mamba Max ESC
15T pinion gear with the standard 50T spur

I just tested it on the street outside and I'm quite happy with its performance. It could probably do with a 16T or 17T spur, but I'll make that decision after I give it a go on the track.

Let me know what you guys think. I'll take a photo with the batts in when I get home.

More pictures here :D
