I have been giving this some thought if there are any massive gains to be had changing up from a 1717 to a 2028 apart from more torque, now the 2028 has a max rpm of 30,000 and the 1717 has a max of 45,000 so if i had two cars the same with the same gearing for 34v on the 2028 i would get 26,520 rpm and for 25v on the 1717 i would get 39,500 rpm so for about the first 3-4m the 2028 would pull away with the higher torque but the the rpm of the 1717 would win the race,correct me if im wrong but the 2028 can push 10hp and the 1717 is about 7-8hp so if you got a 2028 in a losi5 that is about 12kg plus the weight of the extra cells to get 34v then the torque is usefull but like my vader with the 1717 in that is about 4-5kg not as much torque is needed so higher rpm is better.
What do you think?
