awhile back with one of the online "garage sales" i picked up some tires that turned out to be 7" and weigh over a pound each, but they were so cheap i had to get some of them
so... if i install these tires on a rc8t or a converted 3.3 revo and gear for 20-30 am i still asking for trouble.
with the rc8t i can gear for around 23mph as lowest
with the revo 3.3 i can also gear for around 23 as well
i do want the low speed and huge tires but i also would like to keep my drive train and diffs intact
i have 3s 4s 5s for power and 10t, 13 ,15 ,18 tooth pinions so i have options
any suggestions or previous experience would be helpful
those speeds sound good to me for large tires gearing for 40 + mph is where you get in trouble, depending on you motor choice 6s would ideal if you choose a low kv motor, your drivetrain should be fine with those speeds
you should be able to gear up to about 30mph without any issues. i ran some heavy 7" tires on my flux geared for 40mph and everything stayed cool.....until i used my SMC 9000mah 2s lipos. everything was still cool except the lipos. they swelled quite a bit (as usual). my turnigy 30c batteries barely got warm as usual.
They say a good mechanic only needs 2 tools - WD40 & Duct tape. If it moves, and its not supposed to, duct tape. If it doesn't move, and its supposed to, WD40.
