With the CG staying at the same spot, what effect(s) does shortening or lengthening the distance from the leading edge of the wing to the prop have on aerobatic performance?

I tried a search on this topic, but I don't think I hit the right phrase.

TIA,

Not much difference at all...Flying wings with the engine mounted right to the L.E. perform fine aerobatics...

I don't think you would notice anything.

The main difference is the way the weight is distributed. The more the weight is concentrated near the CG the lower the moment of inertia and the less force the control surfaces will have to exert to maneuver. Also, the lower the moment of inertia, the quicker any oscillations will die out. The lower the moment of inertia the crisper will be the control response. The farther the engine is from the CG, the greater will be the moment of inertia in pitch and yaw.

I agree with Ollie

A good example is the Sopwith Camel. Not many could outmaneuver it.

That was what I was hoping to hear.

I just got back from TOC. Quique Somenzeni flew a Yak 54.
During his free style he was able to flip the tail almost 90* each side during a verticle down line quite a few times. It was awesome!

That's the kind of thing I was thinking of by centralizing as much of the mass at CG as possible. It should make for quick flip style manuevers (like the waterfall).

The key would be build the tail light enough to keep the engine as close in as possible.

Is that a correct statement?

I am going to test this out in the next month or so.

Thank you very much for all your responses!

think, funfly.
like the Dust Unlimited and Lill Rippy.
you cant mount much closer than that without being on the wing
