Hirobo Vertol restoring

Some time ago i bought this Hirobo Vertol in bad conditions. Now i began to restore it. I will convert it in EP with the right motor and support. My goal is use 6S lipo with stock CH-46 gear ratio. With the current setup i can use the stock clutch and bell.

I fitted two old Futaba G301 piezo gyros.

Here the link with the pics when the Vertol landed here.

In the bottom  there is a short movie of maiden flight. Only a first test to understand if the vertol could fly.
