I was told this The Pegasus is a really nice pure floater but it does, IIRC, have a reputation for flutter at high speeds.

Cheers! thanks for the heads up Peter .

Q How to cure or help improve the wing from flutter with little weight increase ?
anyone ?

Hi again, rct. I'll add a link to a thread on the Pegasus.

I don't think that the flutter is a big problem and I have only seen one or two comments about it. I just wanted to mention it because in your original post you mentioned that you were looking for a wide speed range and the Pegasus is considered to be a "light lift, light wind" specialist. I haven't seen anyone suggest that one would want or need to beef up the structure. If you do get one and you do find that you want to increase the stiffness a bit then the lightest, simplest, and cheapest way is to simply use clear packing tape along the spar of the wings. I have even used diagonal pieces of tape to add washout to the wing of a foam ASW28.

Cheers!

BTW. Here's a link directly to the Topmodel cz site. Many of their gliders are available direct with a ARC (almost ready to cover) option. The shipping is expensive but if one picks a day when the exchange rates are favorable then it ends up being close to a push with a covered version from a U.S. distributor.

Cheers again!

I'm always happy to (try to) help!

I don't know anything about the Leopard motors but the Suppo motors, also available from altitude, have a lot of fans and I'm seriously considering trying one when I need another motor.

Cheers!
