I was thinking of taking the Avistar and removing all the dihedral in the wing so it is a straight wing instead of with the dihedral.

It has the semi-symmetrical airfoil, so that coupled with the wing w/out the dihedral, I think could make for a great, very fun flying plane.

What do you guys think?

If you already have the Avistar and want to save on a new plane this might help to gain additional abilities and handling of a more aerobatic plane. However, if you have the money get a Four Star, they say a second plane doesn't get better than the all mighty 4*.

Removing all the dihedral on an Avistar won't make that much of a difference in aerobatic ability which is pretty good any way but it will make it a bit harder to land. I would just leave it. I have a 60 size Kaos with a flat wing and I am actually considering to cut the wing in 2 and add 2" dihedral. [8D]

I second the 4 Star idea I like the 60 size....If I were to get another 4 Star I'd shorten the wings a panel on each side, add winglets, and put a 100 4 stroke or a 75 AX on it

IF looking for something similar to Four Star but cooler looking....The Hanger 9 Pulse.

There are lower cost copies of the 4 star, you can get a faster building arf with pinned hinges and engine mount already installed for $99 that flies equal to the 4 star, in fact the larger wingspan really makes floating it in for a landing a pleasure. It's the Dolphin.

A World Models Sky Raider Mach ll is another $85 plane that handles well, again pinned hinges, engine mount installed, probably one of the quickest to build arfs out there, 4 hours.

I've flown the Avistar and removed the dihedral, and it had a much better roll rate and was an enjoyable flying plane without any added difficulty in landing or taking off.
