OFNA Ultra GTP / MBX conversion

I am very happy with the kb so far. I have put about 2.5 packs thru it, and everything seems to be staying cool. It has quite a bit of power, and cand draw the batteries pretty hard at full throttle. I have the punch control set at 20%, and may move it back up to 50% for less wheel spin out of the hole!

The solid center gives it a different feel to a buggy, but I am used to it from driving shaft drive 10th scale cars. Still prefer the diff in a buggy, but it is cool drifing this big car around the parking lot!

The mm seems to be ok with this setup. I had a novak cap on the mm, but it fell off. I could not get solder to stick to the joints on the board, so I will attach it to the input leads near the board. The esc ran noticably cooler with the extra cap. I may also put a fan on it, as I have a few 12v units hanging around.

On a side note, what would it take to have the fan temperature controlled? Have some sort of sensor on the heatsink, and a relay or solid state elec. to switch it on and off when needed? Maybe BrianG could whip me up something, given his electrical genius background?!

Are you using flux when you solder? I realize that some solders are rosin core and don't necasarily need more flux but I always use it and it makes the solder flow right away and makes a very strong bond.
