HI TO EVERYBODY!

HERE IS MY NEW ROO I WITH P80 . I HAVE FLOWN THE MODEL APROX 20 FLIGHTS AND FLYES SO GOOD, BUT I HAVE A LOT OF PROBLEMS HANDLING THE AIRPLANE IN THE GROUND. THE AIRPLANE IS VERY UNSTABLE AND IS REALLY DIFICULT TO LEAD THE AIRPLANE STRAIGHT, SPECIALLY ON THE TAKE OFF RUN. I TRIM THE AIRPLANE ON THE GROUND AT A MEDIUM SPEED BUT AFTER IN THE TAKE OFF RUN AT HIGH SPEED THE MODELS ALWAYS GOES TO THE RIGHT!!! AND SOMETIMES THE AIRPLANES TURNS UNSTABLE AND THE RIGHT WING HIT THE GROUND AND I HAVE TO ABORT THE TAKE OFF. I HAVE TRY DIFFERENT STRUTS (ROBARTS, EUROKIT, MY OWN ONE DESIGN ) AND WHEELS (EUROKIT AND INTAIRCO) BUT WITH NO RESULTS. I HAVE ALSO TRY A GYRO BUT WITH NOT VERY GOOD RESULTS.[]

CAN ANYBODY WITH ROO EXPERIENCE HELPS ME AND GIVE ME SOME EXPLANATION AND RECOMENDATIONS ABOUT WHAT IS HAPPENING AND HOW CAN I SOLVE THE PROBLEM?

I ALSO HAVE A SKYJET (ALL COMPOSITE) WITH P120 _NO PROBLEMS AT ALL AND GREAT JET TRAINER. I HARDLY RECOMMEND TO THE BEGINNERS!!![8D]

THANKS AND REGRADS FRON SPAIN
