Now, I could say this is a 'Chinook', but it isn't, so I won't...This machine moves away from previous Kamov-inspired aircraft I've made in the past, and is instead BASED ON certain products from Boeing Vertol. Although their helicopters were built to lift heavy loads, the same cannot be said of this example. It will only fly if just under 100% throttle is applied BUT it is extremely stable in flight with a moderate fuel range. Since it is already so heavy, it does require an external fuel supply, so activation of Group 1 is essential before flight. The VTOL slider is defunct since control of the pitch on each rotor is managed by the throttle. That's about it really and as always, enjoy :D
