Default OS 1.08FSR

I have a brand new 1.08FSR which I am about to break in. The throttle is different than any I have ever seen with a small ball on a stem and a supplied plastic (nylon) device which snaps over the ball. I am used to ball links but this one is very tight. So tight in fact that it will bend a 2/56 control rod. The carb throttle is fine but the ball/link is very tight. Any suggestions please

The ball link is tight so it won't come off. It will loosen up after a bit of use.

Bax, I just started breaking in my 1.08FSR. What a sweet running motor! I have approx 1/2 gallon of Morgans 5% Omega with some extra Castor thru it. Get rid of the electric starter! One light reverse flip and away we go! Could you recommend a prop for a Goldberg Extra 300? I am running in with an APC 15X8. Havn't peaked any rpms yet. What range should I look for when it is run in some more? Thanks

We normally run an APC 15 x 8 propeller on the O.S. Max 1.08 FSR. When it's peaked, it should run in the high 9,000's. You can safely run the engine in the mid-to-high 10,000's. Start out with that prop and see how the model flies. You can try different props to see what performance you get. Just make sure the engine is in the above RPM range and you'll be oK. Any prop that turns in that range and flies the model the way you like is correct.

Bax,
I guess those were bench tests. What was the motor's temp when a 15X8 prop was used and were the tests done inside (A/C room) or outside?. We have 113F here in Phoenix AZ and the motor's temp is greatly affected.
