This small 2 seat helicopter is designed for quick trips where comfort is secondary. The lightweight helicopter is inexpensive in game and sports some impressive efficiency. The helicopter is very bare bones, focusing on simplicity over multi function.
The controls should be pre-trimmed to a recommended setting for no wind conditions, but due to the light weight, additional trimming may be required as weather changes.
The helicopter sports a range of 50+km with no wind, and runs on a 2 cylinder diesel modular engine. The engine can easily be upgraded with more cylinders if heavier payloads are required for the mission. It was not designed for sling hook operations, but it might be able to lift light weight payloads with 4-6 cyl.
Operation is simple, turn on the power, hold the starter until 4+RPS is achieved, and raise the throttle to the desired RPS. 20 (default max) seems to be a good target for flying this helicopter. The PID should hold the desired RPS when the throttle is moved slowly.
