Mancha,
With all models we've had here, and the 2 that have been sent to us, we've found no problem. I am still waiting tos ee a problem aircraft so we can try to get to the bototm of what may have been wrong with a tooling or something ot be sure we avoid it in the future. All kits in stock, and all the kits our R&D and design teams are flying, are set exactly as called for and fly perfectly. additionally i have talked to not less than 100 VERY happy owners of this aircraft who have no problems at all.

please, all BE SURE you are using the CG as listed in the manual and the SECOND addendum. the first addendum was printed in error. CG is from the TRAILING edge of the wing not the LE. if from the LE you'll have a tail heavy handful....
