Looking into some .12 racing engines, but i'm having trouble. I want a rear exhaust, standard plug, rotary car .12. Easy, right?

Well the problem is, I need to find an engine that fits my driving ability, which is horrible I want an engine that has low to moderately power, nothing over the top. We run on a rough track that is dusty, so it leaves you searching for traction.

I was thinking dynamites platinum .12, rb .12 ( really like this one, but for some reason the rotary carb version of it is almost a hundred dollars more), os tz, the sts S12X3 (i also really like this one, im a sts faithful, but i'm afraid its too much engine for the track.).

Whelp, yeah so I'm in a predicament so I'm open to all suggestions.

I intend on throwing it in a gt2, possibly a ad2, but more than likely a gt2.

Thanks in advance
