Yes, we have heard about that one. I and several others have been discussing on the various IMPACT threads, what to do to fix the tail problem for the past 3 months. Go back on any of the threads and review the various discussions.
Composite ARF needs to fix this at the factory. It's really a simple fix.
AND for the models already produced, CARF should give a discount to all who have purchased the first runs in addition to replacing the broken ones free of charge to their owners.
One man's opinion. Anyone else out there agree with me?

Thanks for the info Andy. If you noticed before the instructions suggests 2-2.5 down thrust. However this did not seem to be compatible with the wing incidences.. Last but not least what is the location of your cg?
BTW anybody heard about the rudder flutter problem for the impacts. Couple of impacts lost their tails. The reps are sending emails telling what to do to overcome the design problem. It seems that some kind of bracing which binds the fuselage sides from the rear anti rotation pins all the way to the stab tube is necessary..
