Hello everyone
I would like to share with you a large scale scratch project that began few years ego and it is now finished and flying.
Some time ago, after completing several scale projects, helicopters and airplanes, I decided to scratch build a new helicopter. I wanted a large, fully detailed that include design and scratch build to 100% scale of the fuselage, landing gear, main and tail rotor.
As a helicopter mechanic in my profession I worked many years on CH-53s helicopters. So it was not so hard to decide that Im going to build an Israeli Air Force Sikorsky CH-53 YASUR 2000 from scratch.
The helicopter is 1:8 scale
Length - 2.80 meters nose to tail.
Main rotor diameter 2.5 meter
Tail rotor diameter 60 cm
Weight 27 kg.
It is electric powered
The Mechanic system including the main rotor and tail rotor are designed and built from scratch by my friend Eyal M. to be 100% scaled detailed. The fuselage is made of composite materials. Devinicell core material is being used to create strength and very low weight.
Tail section is all made of carbon fiber and include the spare mounted
