nitros rarely tune well in cold temps. that is why people mainly run them in the summer. i just sold my last nitro (flm t-maxx) earlier this week and it was a little tough to tune even though it is 40F here. it stays tuned really nice over 50F though. nitros just tune better when it's warm.

i think your best bet is to sell the revo and buy a used e-revo. for the money you have to spend to get your revo brushless-ready even without the motor and esc, you could have already been half way to getting a MMM combo. besides, the e-revo has better battery trays and diffs. an e-revo will also be lighter than a nitro revo conversion.

since there is no demand for nitros here, i recommend selling the revo on either fleabay or rctech.

edit: have you fixed the baja yet? gassers run best in winter. the higher oxygen content in the air gives the engines a little boost.
