Default The best 21.5 for 1/12 scale

Looking to get some input from you guys on what would be a good 21.5 motor for 1/12 scale. This will be for both, indoor and outdoor tracks. Short to medium sized layouts.


Cheers.

No one runs 21.5 12th scale. It's usually single cell batteries and 17.5 and lower in windings.

Japan is a little different, 21.5 with 2 cell lipo. Don't ask me why, but that's how they roll over here at some race tracks.

I know Yokomo has made a 2s battery in the 1/12th scale size for awhile. It's hard to get in the U.S. Now Pro-Tek is making one that is readily available.

I'd be real curious to see what a 2s 21.5 1/12th looks like on the track. World GT, too.

"Shorty" lipos are bigger than 1s batteries. They're longer, taller, and much heavier.

The Yok and Pro-Tek packs are in the actual 1s form factor and match the weights (+/- a few grams) of our 1s packs. They also have a lot less capacity, which I think is a good thing.

here are the spec. 4200mAh/7.4V . 24.5mmx46.5mmx93mm.
I was just saying it is close to ideal of the to F1 shorty performace wise ( the 12th a little faster with higher voltage...

I've got one of the ProTeK 3000ma 2s lipos
Tested it in the VII a few times
produces the same laptimes for about 3m
then tapers off a bit
You'd think 50g lighter would be of some benefit, but the i.r, mah of the pack off-sets any advantage over a shorty pack

Will test 21.5 12th with it next week, and see how that goes
Should be interesting

the revtech 21.5 is 2500kv, that is the highest i have seen for a 21.5

I run the 21.5 revtech ^ lrp stock spec in a mini m06 & its a missle compared to evererything else on the track.

My second choice would a be a tekin gen 2 @ 2300kv

Also, in Japan many people still run brushed motors! lol..
