Currently I am developing a Helicopter with four blades, pitch controlled.
The body has the lenght of 30cm. I estimate the weight 120gr.
The rotorhead is now 90% finalized. I hope to start first tests in the next weeks.
Gear Ratio is currently set to 1:13. May aim is an rpm of about 1300 rounds per minute.
The body (an CH-53) is made of carbon.
More details an photos will be added soon
