I just read the FAQs on breaking in (I'm new to HL tanks myself) and white lithium may not be the right way to go. I'll have to get to the local store & get some white lithium grease pronto! Once out in the grass just for a quick test, once on the driveway, & mostly just some quick runs inside on a hard floor. I haven't been running the tank more than a few minutes a day & probably not more than 10 minutes total yet, hope that didn't hurt anything already. but even without looking into the FAQ yet, I ssume it's probably important to first clean out what's there, then get a good amount of new gear grease in there before I should even think of a break in Yes, thank you for the reminder maintcoder. Don't forget to break in the motors and gear boxes per several methods available in the thread in the FAQ section!
