anyone know what size spur gear is the best for my erevo 1/16
i would go with a 50 tooth spur gear
With great brushless comes great responsibility.
and pinion gear ???
depends on the tires and a few more factors .on a track you don't really need too tall of gearing . maybe 25t unless it's a track with some long straights
should i go with 3s or 2s lipos
3s might heat up a bit much if you run too long.
i only run about 5 minuets at a time
gears really determine what your doing vs what tires and motor you have. cause what iv seen is the brushed and brushless are geared different. like my stock gears were 26/50 with the 3.25 tire on a brushed motor. i run around on dirt messing around but bout to make a crawler out of it small pinion big spur and a trans gear flip. but if you want speed go with bigger pinion and smaller spur but watch your temps like funny said. might have to just get a couple of each and run and see exactly what you like.
In what class?
On what kind of track?
I ask because...
1. 3s is almost 100% likely to be illegal for the race.
2. Stock Traxxas motor is illegal for most racing, but it depends on the track & rules.
That being said, for almost any kind of racing you want acceleration over top speed. The way you charge your batteries is almost as important as the gearing you run. If you give more information on the track, the community can give much better information.
Why is the traxxas motor illegal?

There is no official 1/16 class. However, a good number of tracks have a novice class and a mod class. You can only race a certain amount of time in novice, and if you managed to find a track that let you run cross scale in the open class, you would be a nuisance to the serious drivers. Thats why I said depends on the place. Some places use ROAR rules, some places are chill, some are uptight....it depends on the track & rules.
Lots of places will let you run your own class if you bring 3 or more people. They are a business after all.
I race in novice with the MERV each week (in novice due to no mini class). The setup I use is 23 tooth pinion with stock spur, 2S lipos (3S is way too much), relux wheels with Bro code tyres, ofna 1/12th rear wing, 90wt oil, HR shocks with black and tan springs, hitec servo and probably some other things I have missed. With that setup I win the class each race, but it is just novice. The car is a handful and you have to drive very carefully. If you can't control your finger then there really isn't much hope.
The track is a 1/10 scale outdoor hard packed limestone track.
