I have 2 models, same plane from the same manufacturer.

only major difference is powerplants......but same diameter prop and pitch

in a knife edge, both models do a nice knife edge flying from right to left...however one flies well from left to right, and the other tucks towards the belly.

not sure what difference I'm dealing with........

both are balanced with Great Planes balancer, at same point

measures with incidence meter, nothing I can pin down, but thats not the first time I could not find a difference with the meter that effected the flight charactoristics of a model....

I'm open for thoughts and suggestions

thanks
