Which solder did you use for the bullets? You can just re-shrink the MGM. Make sure to hold the lighter as far away as possible so you don't fry the internals. Why not retrofit your motormount to be adjustable? Why would you (in your right mind) gear so high?

Not sure what solder exactly, i just bought it from the electronics place. Its 99.3% tin and .7% copper if that helps

. Good to know about the mgm, i'll make sure to do that. With the gearing, i had no idea where to start because AFAIK there are no others trucks with the same ratios as this, so i just picked 16t, i didnt think id be THAT far off the mark

I think i might try fit a 50t spur on, to get this gearing thing sorted, i might have to notch the frame rails though. I'm still not sure... I could mod my motor mount to accept a 14t pinion, but i dunno if that will be a big enough drop.

You can do this:
(You have a 42t spur right??)
http://scriptasylum.com/rc_speed/_gear_calc.html
Using the bottom calc with 42/16 gearing it says 31mm shaft spacing. Without changing your motor mount, you can gear 48/10 with 31mm spacing, leaving your motor mount the same, bringing you to a easier 50mph... (probably closer to 45 when all factors are considered)
Here is a 10t pinion and some 48t spurs, not sure which config you need:

That is genius!!! I would've never thought of that. Thanks BL_RVO, i'll get right to it

I might also try out 46/12

No problem, always willing to help. 46/12 is too high...

It's called a learning curve RVO. Anyway Jordan that lose connection probably caused most of your overheating problems, but you still want to start out easy with the gearing up front to see how it handles first. Then as you see the data (IE: temps, speed, & operation) you can gear up until you reach a happy medium. I do hope that you did not do any damage to the ESC.

Just clean out that plug and resolder it correctly and you should be fine with that. I would look real closely at the other connections as well. Then work on getting your gearing correct according the the recommendations from Lutach.

Sorry Jerry, i didn't see this post earlier great advice. I'm going to go with the recommendations of Lutach an BL_RVO and gear it for around 50mph. I don't think i did any damage to the controller, all the components look ok, i did stop straight away when i saw it at 180F
