Great job Steve. The FJ1 is also one of my favorites. The lex does move the CG forward, I am glad you got it worked out. A bigger, much heavier model would have probably not survived .

Lex?


Forgive my ignorance. What does LEX stand for? Leading Edge ???

Thanks,
Eric

LEX means Leading Edge eXtension

On the FJ1 it is the section ahead on the wing, at the root. One of the most common examples would be the F/A-18 Hornet.

Thanks Guys,

The next flight will be video'd.

A big FJ-1 will be awesome. Here's an idea of where the CG will need to be placed..........don't go anywhere near tail-heavy!

Indeed, it makes me question my conclusions. But you can't argue with the facts.............. it went from an out-of-control monster to a sweet flying pussycat.

I have heard of others like this, namely the Polikarpov i16, needing the cg almost on the leading-edge.

Normally my guess would be an incidence issue requiring additional nose weight however knowing Steve's tremendous building skills I doubt that is the answer.

these small models tend to need a farther fwd cg than larger models. plys all that fat fuse forward of the cg changes things a little....panthers are the same way...they like the cg way up there.

The repairs, paint, pilot and noseweight has brought the AUW to 78g.
