I bought a Saito 150GK as part of a RTF setup. This is my first Saito, actually my second but the 72 is still in the box. I've been running it on the ground and it sounds pretty good, strong pull with the 16X8 prop.

The guy I bought it from has a line running from the crank breather to the exhaust pipe, like a pressure fitting on the tank. Is this the correct way to setup a Saito? I would ask him about it but I lost his phone number and email addy.

Here is a pic so you can see what I'm talking about.

Should I plan on doing the same to my 72?

Thanks

p.s. It's on a Hangar 9 CAP; I'm trying to finally get it in the air. Should I run 15% or higher fuel?
