Guys,

Went round a friend's to see how his Impact was coming along and he had shoved it in the corner ready for the bin!! He has aeropoxied all tubes/anti-rotation pins in for the tailplane and when he re-checked the alignment he found one tailplane side is 0.25 - 0.3 degrees out of alignment with the other. I thought it may have been his incidence meter so I tried mine but found the same.

He is going to do a lot of damage to the fuselage trying to pull the pins etc out and re-align them and as he is 'only' a sport flyer who thought he'd have a go at pattern I tried to tell him not to worry too much about it. He is not going to compete - just wanted to own an F3A type model and fly some basic schedules.

I have to be honest now and say I'm not too sure how severe an affect this will have as a) the incidences on my models are right and b) I haven't flown pattern seriously either to really know if it would be a big detriment.

For those of you that fly pattern do you think he should just leave it and trim it out at the field as per most sport models or will it have a big enough effect on trying to fly some of the more basic pattern schedules that he should grin and bear the pain of trying to rip it all out??

Thanks,
Mark
