I will give you an idea that I got from my Multiplex Solius glider. What they did so that you could vary the CG was to put a recess into the tail where you can place steel balls which they include. They then hide the balls and recess by covering them with a decal (the big KM on the tail). Maybe rearward of the tail wheel assembly you could carve a recess out and add the weights there like Fred suggested and then cover with appropriate colored tape or reinsert and glue the carved portion back in place. The point would be to do this as far back as possible so that you have as long as a moment as possible so you have less weight. Or you could just put it back in stock form by buying a motor?Lauren

I was rereading your post and you said that the plane is tail heavy without the spinner on it? If so dump that spinner and buy a new plastic one then you can slide the battery forward and get your CG right. Spinners are cheap....Lauren

I have never flown this plane. I bought it from my instructor who had flown it. Not sure what changes where made before I got it.Lauren

G'day FIB,
I just measured the prop on the FMS Olympus [650kv donk and the model lives in my lounge room, lucky am I not???;)] and it measures at 15".
The Mustang Measures, for the same purpose of measurement, 14 & 1/2".
Some of the earlier V7 units came with spinners with cut outs to suit a two blade. If you can locate one of those, the Olympus prop might be an option.....I did say MIGHT!!!!:D:D
This is one thing I have not done so it is total guess work on my behalf.
Regards and respect
Daryl

Maybe a different spinner, check out True Turn or, if thats too expensive, maybe find out what the stock spinner was. If you have to put 2 1/4 oz at the tail end of the fulcrum, that's got to be one heavy spinner, or the prop maybe too heavy, a wooden prop may be better. don't know what the length of your plane is, but, for arguments sake, lets say 30 inches and your CG is at 25 inches from the tail.
25"x 2 1/4 oz=56.25
56.25/5"=11.61 oz
If you need 2 1/4 oz at 25" aft of the CG, in order to balance the fulcrum, the front end of the plane, ie, the prop and spinner would have to weigh 11.61 oz. at 5" forward of the CG.

Assuming you mean a hub/shaft that bolts to the motor bell...Only thing you can do is try.
The fit has to be exact or the hub won't center properly.
Unfortunately, the makers seem to like being 0.5mm off from each other.FF gliders and rubber power since 1966, CL 1970-1990, RC since 1975.
current planes from 1/2 oz to 22 lbs

This is a link to the specs on the T-Motor. http://www.hobbypartz.com/02p-motor-...530-kv570.html Not sure how to interpret them?
