Mike for what it's worth I am running a s.12 in my rigger with a cowl half the cooling fins cut away and no water. The motor don't get hot. Just is what I am doing not saying it's the only way but it works for me

Yup, you may want to just keep it air cooled. It's easy to over cool a .12 using water.

How does that 12s run?

 

[mike walker]

Mine still almost runs to cool, It don't run bad 50ish there is more there and I am working on it but it very dependable.

got me a second place at Hobart just for the fact that is dose run every time. A wise man told me you don't have to be the fastest to win. but David P still put it on my butt. There were alot of real fast .12s there

Try letting that engine heat up before you launch. They love it hot. With 4 oz of fuel it's kinda hard. to finish a heat if you launch to quick -Launch under a minute.

Keep CKing the head before launch You want it almost hot to the touch.

Mike,

No cooling needed on a 12 motor if you know how to adjust

the needle valve. Run them a little on the rich side and after

a few laps they come in pretty strong. Remember not too much

propeller cup. Lock your car when you travel.

Good Luck,
