I was curious what you recommend for a hop-up parts manufacturer for the tmaxx. I am looking for aluminum parts and good quality. Also what would be a good site for online ordering with good parts availability. So from what I have been reading, I should stay clear of integy parts. I usually do my online shopping with Great Hobbies out of Edmonton, but all they carry is integy. Any suggestions greatly appreciated, to cold to break in engine so I figure now is the perfect time to start upgrading.
