Aris, most guys on this forum that have Yaks say the the distance between the spinner back plate and the cowl lip is about 3/4 to 1 inch. If your standoffs give more than that you may want to consider cutting them off a bit.

I think longer protrusion of the spinner backplate is a good thing. Spacing the prop out allows more air to flow around the cowl and become thrust. I believe QQ said as much early in this thread. I also need the motor further forward to balance the plane with pipes and the CG location I like. Otherwise, it's a matter of aesthetics.

Hello.

Well, I was also concerned about this problem when I was building mine, but I discovered this distance is normal in a Yak.

At first, like underdw said, this is not bad, cause you get more air to flow to keep your engine cold. I even not use spinner in my Yak...

And, considering this Yak a semi-scale, take a look on this distance in a full scale plane. The pic is below...

Hey Guys,

Side line question here: I am about to pull the trigger on one of these 102" but needed some info, Can someone give me the measurements for the height of the plane while on the ground? I need to know ground to top of rudder? also ground to top of cowl?

Thanks, Bender

I can give you this numbers, but I am keeping my plane in a hangar on our field. So, I need some days to go there and get it to you.

Oh, and do pull this trigger. You will do a good shot.
