I wouldn't start with a 7.5t myself. With some experience its great but I'd start milder - something like a
10.5t or even
13.5t. Its not like my cars run slow with them, but the power is more manageable. Cheaper too.
But certainly brushless, and I'd recommend sensored over sensorless, especially in a 2wd.
And the best cars in 2wd at Bury are old RC10's. Any model you like as long as it predates the B4.....
