I recently took the engine out of my alpha trainer to put in another airplane. I still have the flywheel on it, and when i tighten up the spinner against it, the spinner deforms slightly. What do i need, and does anybody have a website? Thanks guys.

I assume you are not using the 3-blade spinner that came with it? You will need to find a spinner with a flat backplate or a larger diameter recess like the 3-blade spinner had.

No, im not using the 3 blade prop. Its going on a Super Sportster that I'm finishing building.

Like Bruce said, you need to either use a flat-backed spinner (Like the ones Great Planes makes) or get rid of the flywheel.

You need this to make it work. [link=http://www.horizonhobby.com/Search/Default.aspx?SearchTerm=evo100219&OverallCatID=]PROP DRIVER[/link]
However I must have got the last one a few weeks ago and now they say late May for availability.

Skynyrd Man is correct. You will need to remove the flywheel to install this piece or find a spinner with a flat backplate. The drive hub is probably the easiest/best solution. You will lose just a smidge of your low idle but not enough to worry about.

Leave it to Skynyrd Man to take the last one. Nice guy. Harummmph!!

It's still in its original package, any offers?

You need to replace it with part # EVO 040219 (prop driver). Dennis

You could also cut a small circle of 1/16 ply the same size the the front of the existing prop driver (note not the same diameter as the flywheel, just the grooved section). Then drill a 1/4" hole in the center for the prop shaft and you have a quick easy spacer to offset the spinner off the flywheel. This is what I did and it works fine.
