well i opened this can of worms with my prior post of,arf quality/safety. thought you might like to know that the hangar 9 arf just wasn't flying right. i brought it home and out of curiosoty i checked the wing incidence and it was off by posotive almost 5 degree's. trimmed out the fuse sides and now it flies fine. what i don't understand is if an arf is made in a factory shouldn't they all be produced to the same tollerences? like i said that was the first and only arf i will ever buy.
