i need a new project

[t-maxxracer32]

well i have some 645mg servos that i could use for brakes and that will allow me to save some money!

also, i too was wondering why i needed that 375 dollar esc but i figured it was needed with such a big truck...

i have a question.

if i get the 1y and use 4s on it how will that compare to the 2.5d on 5s?

i will never go 6s but possibly 5s.

what would you think the runtimes would be with the 30c 4500 batteries?

Oh, sounds good.

Last week when I raced my truggy (5 or 6 5 minute races in the middle of warm day) my unmoded quark was working well with just the rcm heatsink and no fans, running the 1515 2.5D (1700kv) on 5s, so I would have thought that the 16018 would work well too since people say the MGM's run cooler, but tallyram's truggy that was linked to uses 22418 ($375 one), so maybe there's something I don't know.

I don't have both to compare, but on those voltages the 2.5d should only be ~1000rpm slower, so top speed with the same gearing should very close, but with the higher voltage the 2.5D should have a bit more torque and lower amp draw. Meaning a little bit less volt drop in theory, which could make up the rpm difference and there should be a bit more room to gear up. Basically I think they should be pretty close, but the 2.5 should run a little bit cooler, with a bit more torque and runtime.
