Team Orion 3.5T Motor in Turbo Optima re-re?

[sundevil67]

Just took my Kyosho Plazma RA for a spin & without enough traction I can barely get past 50% throttle before I spin. It's a bit over-powered with the TEAM ORION VORTEX 3.5T brushless motor. I'm wondering how it'd do in my Turbo Optima re-re instead... The Le Mans 240s I run in that is smooth & the car handles great, but it's a little slow. Would going from 15.5T to 3.5T be completely insane though? Forgive my inexperience with the finer points of brush-less motor power... Back in the olden days, I could swap motors I used in my 1/10 buggies & 1/12 pan-cars & it was pretty much 13-15T vs. 18-21T so it wasn't a gigantic difference. Now I pretty much buy what the manufacturer recommends & leave it alone...3.5T motors didn't exist. Will I just completely shred my transmission & fry my ESC?

I think the tranny will be fine but not sure on that esc Its worth a try and will be fun no matter what happens!

What's the point of overpowering a car to the point it's undriveable?

My brother put a 4.5 in his newly built Avante and made 1 pass....that thing was going so fast thin it flipped and slid on its roof forever! needless to say it came out immediately afterwards

I'm building an original Turbo Optima with rere drivetrain to use as a runner, I opted to run Kyosho's high velocity gear with it. That is the blue spur gear, 41 tooth pinion and OT206b high velocity chain guides and gear cover. For added slip/protection I'm running a rear ball diff. With all that, I didn't plan on running anything faster than an 8.5 turn.

I don't want it to be uncontrollable. It's hard to have a frame of reference since I've only experienced a 3.5T motor in the 1/12. My Turbo Optima is definitely too slow with the 15.5T, so I just had the thought. It sounds like it wouldn't be a good idea though. I'll make a pinion switch & see how it performs on the track before I make any decisions about replacing the motor. Maybe the better swap is to stick the 15T LeMans into the 1/12 & find something more in the 12T ballpark for the Optima. Thanks all!

A 10.5 turn would be an ideal motor for the optima. Not too fast, not too slow.
