I understand trying to keep the cost down, but seriously, get a temp gun andsave yourself some money on burned parts. The touch test is pointless, everybodies threshold for pain is different. $20 or $30 is cheap compared to motors, ESCs, and Batteries. If your LiPo puffed your drawing way to much current for it to handle. 5000mah x 20C = 100A. You should give yourself a cushion on that though. Kind of explains the hot MM to though. Going to have to work on the gearing to get the amp load down. I made an aluminum U bracket to go around my MM that I put in my Maxx. Put a large hole in both sides of the bracket and one in the top. There is room for 1 fan inside the U blowing right on the heat sink. The other fan is outside the U, blowing in through the large hole I put in the bottom of the case. I made smaller holes all the way aroundthe case to let air out. Servo tape and a zip tie hold the ESC in the U, drilled and tapped the AL for the fan screws. Made the ends of the U like L brackets and screwed them to the chassis on the Maxx. Using a CC BEC, still had a little steering issue, so I added a glitch buster cap to the Rx, but both servos died. New 333oz HiTech fixed the steering. With twin fans on 4S geared 18/68 motor (1512 1Y) and MM stayed under 150 until the fan on the heatsink failed. Thermalled right after main, but temp was down to 178 by the time I pulled the lid. Batteries were only 104/105 at the end of that run, but 2 @ 2S 8k can handle more than 1 @ 3s 5K. The MMM never went past 120 on 4S geared 20/68. I hate to say it, but the MM just isn't really meant for Monster Truck and it's going to struggle. If you can wait for the new version, the MMM should solve your problems with the ESC. Getting batteries that can feed the truck is a different story. Check with MaxAmps tomorrow and see if they can help you with the puffed 3s5K though. IMO, good people there and at Castle.
