I tried this within another thread with no response so I thought I would try it again.

Thanks to everyone for there useful information on the Aresti 40. I'm glad to say that I am finally enjoying mine. I've only got one problem that I have not been able to fix. From straight level flight pulling up to vertical or pull up for a loop my aresti wants to roll out to the left. Lateral balance was checked and added 1/2 oz. weight to right wing tip to balance. experimented with right thrust on engine and adjusted elevator halves. I've made adjustmenst one at a time in order to see if it worked. It has gotten better with these changes but its still not right.

Tested it inverted to vertical or outside loop and the aresti will stay straight.

At first I thout that maybe I was using to much elevator so a I tried a softer touch with low and high rates. no change.

It has been suggested to me that there might be a slight warp in the wing I haven't had a chance to check that yet.

Thanks for any help. Ken

I assembled one of these for my brother. Could it be that one of your pushrods is flexing under load? I swapped out the 2-56 ends on the elevator rod for 4-40 and used a Dave Brown fibreglass pushrod instead of the wooden dowel.

I used 4/40wire but i used the dowel rod. but it could be a possibility I will add it to the list of things to check. Thanks

If all else fails, mix it out with your radio (I'm assuming you have a radio capable of this).

I had this same problem with a .40 size sport plane. It turned out to be a mixture of thrust loading, and rudder issues.. A high angle of attack would wash out a bit of the vertical stabilizer, and cause the plane to skid pretty easily in that configuration. I just got pretty good at adding a bit of rudder when entering verticals. Like the previous post said. If you have a computer radio, you could perhaps mix out the flaw.

Yeah I can mix it out but didn't want to. I will give it a shot if the weather gods are good to me. They keep talking snow and windy...Thanks for the advice if I find whats wrong I'll be sure and post it. Later...........Ken
