Hi!
Any plane that snaps in either a sharp turn or in a loop...is to heavy!
Or more precisely has too high wing loading!!

I just got back from flying my 180 seagull extra 260 I cut the throw back on the elevator and still got it to do it a bit but its almost gone so a little less throw and problem will be solved.
To charlie1960 Dead on analysis for me thank you for the support!!!![8D]

The comment about plane being to heavy came from JAKA, not me. Weight has nothing to do with it. Like Charlie 1960 I also suggested it was due to to much throw in the elevator. One of the first things we do at our field with a new plane is take it up high and give it full up elevator while climbing to see if it will snap. If it does we land and take some throw out of the low rates. Alot of the guys leave it in on the high rates because they want it to snap on high rates if full up given. They like to see em corkscrew. Glad you solved the problem.

It is tail heavy and too much elevator throw. .
i have a seagull extra 260, 90 size. Saito 120, 16/6 prop, 8700 rpm, 9.5 lbs. The plane fly’s great, but when ever i feed in a lot of elevator the plane rolls to the right. When i do a tight loop the plane corkscrews to the right. I’ve posted here before and was advised to cut back on the elevator throws. I started with one inch up and down and now i’m at 3/4 inch each way. The manual says you can go up to 1.25 inches of throw. It’s a little better, but still does the corkscrew thing. I’ve sealed all of the hinge lines. The plane is balanced wing tip to wing tip and i’ve moved the fore/aft balance back and forth. The wings are not warped. I’ve measured everything with an incident meter. I’m at my wits end. I’m sure there are other people flying this plane. Is anyone else having this problem? And yes the elevator haves are moving together and the control rods are not flexing. The aleirons are not moving when i pull up. I’m in a very small club and fly by myself most of the time. I’m about ready to buy another plane!!!

skyhawk,
you might check to see how much right thrust is built into your engine. A couple of weekends ago i was flying my arrow and while it flew horizontally with no problems and would roll normally, when i pulled it into the vertical it pulled to the right, and loops came out as corkscrews. Turned out that after some routine engine maintenance the week before, i'd remounted the engine and it ended up cocked off to the right. There should probably be 1 to 2* of right thrust in your motor/firewall, but more than that could cause the flight characteristics you've described.
