Baffling for single cylinder engines
Hello,
I have purchased 2 3w 85xis for 2 1/3 scale Cap 580's for my son and I. I have made a big investment and I want it to last a while $$$$. Does anyone baffle single cylinder engines? If you would, please post pics, comments, and suggestions. Anything would be appriciated.
Thanks in advance,
Shane

Asked the same question a while back. Here's the link. Grab a soda and a notepad.

Shanes,
I’ll post a pic this evening after work on my 50cc single.
When cutting the cowl for the inverted cylinder, expose enough of the front to allow the air to hit most of the cylinder front. Also, cut as close as practical on each side of the cylinder to force the air to go through the fins instead of around.

If your cylinder head pokes out of the bottom of the cowl enough you will not need to baffle, unless you fly in exceptionaly hot weather as a norm.

RE: Baffling for single cylinder engines
Thanks for all the replies.
Mike,
on the Cap, it is big enough to where I don't have to cut out for even the spark plug. I had a AW 29% Katana that the DA50 did stick out enough, but that is not the case on the Cap. on the pros vs con I get to enclose the engine, but I am worried about the cooling.
Jake,
Thanks for posting the pics. Now, on the two holes on the original intakes, do you have any kind of tubing going from that to the engine?
Thanks again everyone,
Shane

Shanes,
There is no tubing attached to the small holes on each side of the spinner. I opened the holes to let ventilation around the ignition and battery.
I tested this configuration last weekend. The baffle in front of the bottom exit hole seems to have the biggest effect in venting the hot air from the cowl.
