Questions?? Has anyone tried putting a low turn BL motor inside a Tamiya M03/M04/M05 chassis?

I'd like to know what the results were and if the gearbox could handle it without needing a rebuild too often. Reason why I ask because I'll be installing a 3.5T or 4T motor in a M04 chassis. I'll be using an aluminum spur + aluminum ball differential + ceramic balls + hollow carbon gear shafts + full ball bearings.

Depends how much money you've got to replace gears...

Because this is what's gonna happen within about 5 mins

Actually I ve got good result when I installed Hobbywing EZrun 5.5t system in my M03. I dont know in a long term the gears will melt coz i ve had mine installed for only a few runs, it was crazy fast though.

Hmm...seems like the gears won't melt but might break due to enormous torque. Maybe I need to lower the punch setting on the ESC to the lowest setting.

we use either the 27 turn purple bull GM motor or the 17.5 turn EZrun set up in our swifts

they are quick and seem to last , i use mine indoors on a small track and it goes like stink

i think with any more power you will rip the little thing in half !!!!!

Having a 3.5T motor in most cars will leave you having to replace the gears, diffs etc. quite often, even if they are aluminium, i suppose if you take it easy, depending on what battery you're using it could "work" well. Not too sure on putting it in a Mini though :P

sorry to bump an old thread, but I didn't want to start a new one for the same thing...

I just acquired an m03-m and am looking for a good motor for it.
I won't be racing in any clubs or at tracks, so no restrictions.
so what's a good brushless setup for these little cars?

In the Australian section of these forums is a thread "Velodrome time" about Minis with low turn motors for Velodrome speed runs.
