Here is the clutch system! The fan bolts to the main gear and 3 independent shoes are kept together by o-rings. It's a quite heavy and a large assembly.

The main shaft and control rods run through the main bearing housing. The pushrods also run through the clutch assembly connecting the main head to the swashplate.

The full setup! You can see that the swashplate is BELOW the main gear and the pushrods run through the main gear, clutch, and fan! Pretty cool and smooth!

Here is the swashplate and connecting rod assembly. The pitch mechanism can also be viewed.

A general view of the right side of the heli. Note the belt runs like a raptor setup with guide pulleys.

Underside view. Servos are mounted upside down. All mini servos which are  Futaba  S-133s.

Beautiful Shell of a BK-177!  Nice little Helicopter! I hope to have it flying someday.

The beautiful OS CZ-15. I have not tried it yet but I am sure it runs like any OS! Smooth!

The muffler is interesting. Aluminum up front and a rubber cover in back. Wonder how it sounds?

The little Hirobo MH-10 has gone to a better home. I never found the time nor interest to get her flying. Hopefully the new owner, Chris will keep me updated on her  progress.
