Can you guys ID this plane? Ive had it a year or two and have never flown it, Im getting it ready for flight but cant find the proper CG, what Im finding is like 5" back off of the leading edge and feel thats way tofar back, or I have to add like 3.5oz of lead to get it to like the 4" area. Something doesnt feel right with it and I cant seem to fix it.
Plane specs are!
Lenth 50" 1/2"
Wingspan 54"
Engine size .46
w/retracts

Seems a kind of Elation Rapture 50... not sure but it's nice!!!

There was an on line CG calculator somewhere, that you entered the pertinent details, and it would answer the question. I cannot remember where, or I would past a link.

I'm confident that it's a WorldModels Zen50. I owned one about 8yrs ago. I had a .70 4-stroke engine. Great flying plane, one of the few I wished I'd never sold...and I'm sure I gave the manual to the new owner.... but that's what it is. You might get some info from the distributing outlet in Livermore, Calif. or try www.theworldmodels.com for some info(I don't know if thats an active link anymore)..but in any case... Google WorldModels Zen50, that will probably get some info too.

I'm also sure its been discontinued... but you still might get a copy of a manual from them.. can't say for sure though... and yes.. its still an active link.

Pitch control sensitivity and the CG location are controlled by 4 things mostly, the size and moment arm of the horizontal tail and the chord and area of the wing. A good online calculator that does all the work for you to figure out those important values is http://www.geistware.com/rcmodeling/cg_super_calc.htm

All you do is measure your airplane and plug the numbers in.

It's an excellent step to take even for ARFs that tell you where they think the CG should go.

For straight tapered wings such as this, the mean aerodynamic chord will be at half the semi-span.
Locate the 30% point on this m.a.c., and project that to the fuselage for the balancing c.g.

Or use a Vanessa rig.

The rig is only useable after you know where the c.g. is supposed to be.
