I got her all finished up and running today. I'm pretty happy with it, I can't wait to solder a Deans onto that 6S and see what she can do as it's pretty strong with a 3S. I've got it geared pretty high so I'll really need to watch my temps but I'm only planning on doing a pass at a time wuth the 6S. It's super stiff with the braces I made and everything from a 2S to the 6S fits in nice and snug.
Man, thats one good looking MT2. Kind of makes me want to get one again! What kind of speeds are you geting out of it?

You still got the vendetta? how did it turn out?
I'm a little bummed. I strapped in my 6S battery yesterday and did a couple runs in front of my house. After the first run I felt the motor and ESC and they were barely warm, so I went for it. It felt like it was kind of cogging or stuttering when I had it wide open on the first pass, and it did the same thing on the next pass so I brought it in. As I was letting it roll towards me the ESC (a new MMP) started shooting smoke out. I went to pull the battery plug and the wires came right out of the ESC, it melted the solder on the wires.
I'm still new to the lipo thing and I probably did something dumb here, but the ESC is rated for a 6S so it should have lasted for a couple runs?
The lipo is a Turnigy 4000mah 6S 40-50C, and the motor is a Novak 10.5 turn brushless.
I need to find a good setup and do some speed runs!

As far as the Vendetta, it's been set aside since I toasted the electronics in that one. All that building and I used it one time and got into the brushless conversion on my MT2. I'll get it going again soon, work has just been really overwhelming lately.

How's your RC18?
how many KV is the motor(or was)
6S is for 1800kv motors if the novak was around 4000kv(like a few 10.5 turn motors) I'm shocked the magnets didn't fly off the rotor. Higher the KV you need to use lower cell counts in BL. Like a 4000kv motor should not be used on anything higher than 2S, a 3500 could do 3S, etc
