I've got a Senior built from a kit but with ailerons added. IF you're wing has as much dihedral as mine, it won't matter if you put the biggest digital servo known to man in those wings, it won't WANT to roll. The plane is made to "re-set" itself back to upright to help the new flyer sucessfully fly the plane. The only way that I could get it to go inverted was to do a half loop and try and keep it there. Trust me, it wasn't happy doin it either. I could get somewhat of a roll if I used some rudder with the ailerons but they weren't really pretty. My dad (the builder of the family) assembled another wing with little, or no dihedral and now I can do rolling circles with it.

Another thought, I had a 50 Saito on my Senior when I was first learning and one thing I found out was that the only time I needed full throttle was getting it off of the ground (grass field). After that, anything over half and it was gaining altitude like a banshee. I'd suggest pullin back on the right stick a little. I concede that when I was throwing around the plane a little, I'd always give it more throttle, and maybe that's what you're doing but if you're just flying around that way, you're losing one of the best lessons that your Senior could teach you- throttle control. The other would be using the rudder. Enjoy the plane and learn all that it can do and that doesn't necessarily mean hucking it around in the air. This plane was made for touch and go's and if you can't learn to control it at EVERY speed, you'll never be able to control your next plane to the best of your abilities either.

Okay, I'll pack up my soap box and move on now. Thank you, good night and don't forget to tip your waitress!
