Well I havent managed a tip stall yet, so it beats the C50, even though mine is quite heavy. I have tried to tip stall it, to see how bad it is, and at what point it comes in, but from level flight it just mushes, then goes into an elevator, and vertical dive it either pulls out or does a parachute. There does not seem to be an inbetween . Only trouble is wing rock in harriers.

Foof, I'm quite impressed that you can measure an inaccuracy of that amount, don't think I could. If you are really bothered, carefull use of the iron when covering it could probably eliminate that small amount of difference.
