Im not sure on the motor wires but that is why that got rid of them on the battery side. The female ends were bending in and touching the heatsink and shorting it out. Thats why the went to the battery wires straight to the board.
Id go with the Losi buggy next. I love mine handles so great.
Yes that Losi buggy is very tempting. Well even if there's no confirmation on the possible shorting of the motor leads, I had to open the ESC to clean the inside and check the fan anyway so I went ahead and shrinked them. I also have a used MMM system as a spare so I wanted to see how difficult it was to open the motor to check the bearings. I had a little trouble getting the end caps off the motor and they got tiny marks on they from the process but I got them off. And yes, one of the bearings needs to be changed. I took the opportunity to change something to the front end cap, I drilled and tapped the mounting holes to 4X0.7 mm threads. Then I drilled the holes of a spare motor mount to 4 mm and counter sunk them to accept M4X10 mm flat head screws. I had that motor come loose on me once but I was lucky as no damage was caused but it could have been worse. M4 screws will hold the motor a lot more securely to the motor mount IMO. I saw someone else do this and I thought I'd give it a try.
A neat little thing I did to help keep the ball ends of the turnbuckles and pushrods from popping off the steel ball. I used two pieces of fuel tubing of the right length on the turnbuckles and o rings of the right size for the pushrods. It really helps.
