Hyper ST Pro Brushless project?

[Finnster]

I would 2nd just going for a MMM. By the time you buy a fan and bec and all that other stuff you end up at about the same price but a less capable unit.

A combo would be great if you can find it, tho I prefer to use higher voltage to keep the temps down. I can get my 1700kv 2.5D on 5S upto 160 after enough hard running, and a 4S/2200kv unit will heat up even faster.

Lastly, I would stick to RCM pinions. I run 16/48.

The HST is a great truck either way, turns awesome and is very affordable.
