What brushless motors are people running in vintage RC10s?

[southern racer]

Hi All,

Hoping to put together a black tub stealth gearboxed Rc10 soon and looking to run it with modern electrics. Just wondering what turn brushless systems people are running in them? 10.5? 13.5?

Will be racing on a fairly large outdoor grass/dirt track versus other club racers using modern 2wd, inital thoughts are to try a 10.5. Esc will be a LRP Sphere Bullet, 65c 5300 lipos etc.

Cheers

SR
