Thumbs up Great!

Many thanks, for the great plane, Nemo!

It flyes how the real thing on the videos! Thanks for the flightcharakteristics, opjose!

Keep up the good work!

It certainly is a fun glider.

Normally gliders don't keep my attention, but this one sure does.

We have a review from a designer of one of the variants of the plane
----------------------------------------------------------------------------------------------

I downloaded the G3 JART, and the flight characteristics are so close to my JART-EPP Jaartvark that it's scary! It flies just like the JART does in good lift. It's certainly gratifying to know that my own spinoff of the original design still retains all the performance that seems to be built into REED's first effort. If the G3 sim model reflects the actual flight characteristics of the real thing, then I've sure got in the real world what I wanted when I built one. Gimme the lift and the lead, and I can make my own classic video like those listed on the JARTWORLD.com website. Check out the videos (as if you haven't already), and you'll see what I'm talking about.

Interesting sidelight; Using the model editing function, I changed the airfoil from what the original design was, and substituted the RG 14 that I build into my Jaartvark. AMAZING. What few small handling differences there were between the original and my design vanished, and now the G3 JART is JUST like my plane.
The physics of this G3 program are pretty impressive, and I'm gonna experiment with other airfoils and get a chance to "see" what they feel like...
(gotta try an thinned RG 15-7.5%-1.8 camber.....hmmmm)

Mike Furcolow's JaartVark variant of the Jart, with the RG 14 wing foils.

This generates a bit more lift at the expense of wing symmetry.

Very nice.

I've updated the .g3x (4 /18/06, I noticed a problem with the texture) unfortunately it looks like I managed to change the name of the base model ! if you have problems with Mike Furcolow's JaartVark variant try this file ...

Umm.. How do I land this thing without lawndart-ing it?

(btw, thanks for an awesome model! makes me almost wish I lived somewhere with wind.. almost. )

The best way to do it that I have found, is to have the plane circle around you at low altitude and approach you from behind, heading into the wind.

Keep the nose pointed slightly down, so that it looses altitude while not picking up speed and you can have it stop just short of your position.

It takes a while to get it right.

You could also sideslip to a landing next to you.

Neither of these are trivial.

Any suggestions from real glider pilots?
