The TT is finished and ready to fly. Motors and ESC units are now harmonised to give identical starting and stopping. All done without buying another program card. Props are contra-rotate to avoid adverse torque reaction.
Flying weight is 10.8Lb/5Kg with LiPo packs onboard. Total wing area is almost exactly 7 square feet.
Just running the model across the drive revealed a landing gear tracking issue but that was quickly sorted by twisting the nose leg slightly until the model ran straight. Other than that, no further problems.
Together, the two motors certainly pack some punch.
