I have done a video on how to convert the H/K ( Hobby King) autogyro control head to one that is widely used in a number of Rich Harris designs. The fiberglass plate used comes in a verity of thickness and is posted on which thickness to use in all his plans. Here in the U.S. McMaster - Carr is a good place to get the sheets.
Also called G-10 plate.
Note : When dismantling the upper mount it is a good idea to save all the screws they will be useful to mount your blades to the new fiberglass plate.

Enjoy,

A quick and easy way to make a blade shaping / finish sanding block. I hope it turns out as nice for you as it did for me.
Well I guess we a limited to how much we can say in each picture.
So after Harding the balsa block it will raise the grain in the wood so just run it over the fine paper on the master to smooth it off. That's why you don't dismantle the jig till often the balsa is dry.
I guess you get the picture in the other post.

Grumpy Bill here:
I am fortunate to be able to have in my possession a set of prints for 'The Panther" an autogyro designed built and flown by Rich Harris. I think a certain rabbit pulled them out of his hat He is in no hurry to return home Joe but he does have an appetite but he came through on this one for me so I'll keep him around a bit longer
Back to the build as you will see it is a very straight forward build with prints in hand cut out all the parts separate them in piles according to wood type and thickness then transfer them to wood and cut out. A basic box frame is used with reinforcing in all the cridical points,Nose, Landing gear, Mast location,ECT.
More to come
