Hi Randy,
your aileron servos have plenty of torque! About twice as much as the servos in the original P8 (and it only had one aileron servo with torque rods). I don't think you'll find original part sot fit your Rossi and I don't know if parts from the new versions will fit, but a new R60F from SMT Distributing is only $129 which is about what you would pay for the replacement parts; so a new engine seems like a reasonable alternative. I prefer taildraggers, myself :-)
