I started with two partial Concept 30s and combined the good parts into this one. I replaced the cyclic and collective servos with slightly faster Hitec ones, and the tail servo with a much faster one, plus a GY401 gyro. It has a Spektrum radio system.

Other mods include the beefier tail control rod assembly, and using what I think are Nexus forks to support modern blades (Align 520mm) which have a 12mm root.

For the first few tanks It's tuned very rich as the engine breaks in. Since then I have started to lean it out and it has much more power than it needs and is capable of higher head speeds than I expected.
