Default Static thrust of BGX-1

I have an old BGX-1 that has never been fired but I want to use it on a 14 lb. 80" plane I'm using and I want unlimited vertical, do you think this combo will give me unlimited vertical performance?

We hate to say this, but there's no way to give you a particular answer. It all depends upon the airplane/engine/ propeller combination. For good hovering, you'll need low pitch, but some airplanes don't fly well with low-pitched propeller.

With the O.S. Max GSX-1, the engine runs best when propped so that peak RPM on the ground is between 8,000-9,000 RPM. To get a low-pitched prop to load the engine in this RPM range, you'll have to increase the diameter. This could cause problems with ground clearance.

The basic propeller we use for general-purpose use is an 18x8 prop. The engine will turn this in the low- to mid-8,000's with the stock muffler installed. Try higher-diameter and lower-pitched props to keep the RPM in the same range and see how it works. That's really the only way to find out which prop is right for you.
