I'm late to this thread but find it quite interesting and informative as I just aquired the 75-91 size I purchased at a swap meet. It came with a Saito FA 115, Futaba 3010 servos X 4 (2 for elevator and 2 for ailerons), a Hitec 605 BB for the rudder and a JR 537 for throttle. It has been completely recovered and appears to be well looked after. Are any of this threads previous contributers still flying their Decathlons? Hopefully they all haven't bit the dust ( planes, not pilots).
