Anyone know of a cooling head for the Pro. 15 that works better than the stock one?
Also are the cooling cans any good?

What's a cooling can?
The 15 pro is a bit of a weak engine for a t-maxx, so it will likely run on the hot side. May be time to look into converting to a 3.3. More power to push around a MT.
Or on a bit cheaper route, maybe look at getting an OS18CV-R. It's also a side exhaust engine, so you can use the pipe/header you have now, but have more power so you will labor the engine less.

My friend has a OS 15 that has a square head. It fit the t maxx but might have a rear exhaust, don't know. It would be stronger I think. I am looking to get a os 18, or a os 21 for my wide stands t maxx.
Might have to stay with pro 15 on one of the trucks until I get more money to spend. Do the fans help cool the motor any?

I couldn't say, never tried.
I ran an OS15CV-R in my maxx back in the day. Wasn't much different from the trx2.5, just easier to tune.

There have been several different size O.S. CV-R engines over the years with square heads. As long as it has a side exhaust/rotary carb and a starter back plate it will fit the old pro .15 TMaxx.
This is the OS I was talking about:

You have to cut some of the threaded crank off to use the trx cb adapter, but otherwise is a drop in.
