But the Big race is tomorrow so you got to do what you got to do. 
I forgot to add I don't bother breaking in the cv .12 stock sleeve or the duratrax one. I've been told by some pretty smart fellas it doesn't need it as neither sleeve is a chromed sleeve. I've do take it easy for a tank or two but that's it, and I've got good lifespan from them. And they do run when ported!!
And the aluminum foil is for when it's so cold you can't get the thing past 170 no matter how much you lean it! Ya, it's really to cold to hold the transmitter. I just need a nitro "fix" now and then.
