Finally got around to doing the big engine.first piece. Still have some finish work on it and drill the bolt holes.

Hmmm, for some reason, that engine reminds me of Bart Simpson.

 

[Danny King]

Lol. I can see that now that you say it.

Wellllll.....Mom always said I had a vivid imagination, if'n yall know that I mean.....

 

[Terry Keeley]

Nice! Let us know how it works.

Very cool! I'm actually looking to do.the opposite, make a water cooled head for my losi engine in my boat. Just curious, why change from watercooled to air cooled on a boat?

 

[Danny King]

Ran 4 runs today, she ran flawless. 97 mph @ 137*
Will test more at my regular and bigger lake.

What kind of boat? Is the engine enclosed?
What percentage fuel?
There are things that need dialed to run no water.
But most nitro boats are
Over cooled.

Its the mono hull I have. Engine is a losi mach 427 out of a buggy. The top of the boat is open and gets plenty of air flow. I wrapped some 1/8 od aluminum tube around thr first few fins just to have something. Currently I'm running 25% nitro with around 12% caster. It's a mix of 30% nitro with 9% caster and 20% nitro with 14% caster.

I’m a mono it will be harder
To use just air and the low nitro makes it harder to run air.
Atleast in the beginning I’d use water and get it really running well.

 

[Mark O'Malley]

What nitro content fuel would you recommend with air cooled setup?

 

[Danny King]

What nitro content fuel would you recommend with air cooled setup?

It depends on the size. .45 and under 65%

 

[Mark O'Malley]

I don't even know where to find that high if nitro content fuel. I know the guy I got the engine from runs 30% in his buggy with the same engine. I also understand a boat loads the engine much different. Are you recommending 65% with air cooled head?

 

[Danny King]

There is several factor. If you are just starting off in boats then I would go water cooled.

If anyone can make this work you certainly can! You are a man of many talents...

Anxious to see it run in person out at Copans pond.

Cool I’m about to do a custom car conversion kit for the 91RS.

Very impressive as anitcipated, nice job Danny!

Hopefully I'll get to see it run in person someday...
