So how do you like the integy rear hubs? I have a pair coming for the flm savvy... Still debating whether to lock it in second, or wait and get the flux parts to convert it to single speed... I have to wait for the 1521 smooth can to show up, and the 10s lipos... The tranny forward chassis needs a certain amount of room to fit the batts, and my primary gearing has to work with that space too... Crap, waiting on parts again
