Angelo Ferraro built several CH601-HD and HDS. The
project presented below is his fourth one. When I asked him if he
will keep it, he said "yes, now that I know how to build them,
I want to keep one for me".
This EA-81 engine has a EA-82 intake manifold. That created some
difficulties for fitting the engine mount and probably a hose near the
distributor. The EA-82 manifold is said to be a bit larger internally
than the original EA-81 one.
The reduction is an older model from Karlo Kuhner (who now makes
exclusively geared reduction drives).
The radiator, a VW model is installed between the engine and the
||Inside the cockpit
The cockpit is insulated with a kind of special foam pad purchased from ACS.
This material is quite special. We did some burn tests with a torch, and
although it ignites under the flame of the torch, the fire stops almost
instantly when the torch is removed (amazing!).
I was particularily interested by the pedals... see below. Those
pedals are higher than the Zenair ones (the vertical tube is 7 inches long
from top of base tube). The hydraulic brake base is a 2 inch tube
mounted at 45 degrees on the base tube.
To attach the Cessna pedals on the pedals frame, gussets are welded and a
cross tube is installed. The top of hydraulic brake is bolted directly
on the pedal.
Notice the master cylinders that are manufactured locally by Claude
Guilbeault. I will have the same on my plane. Claude also
manufactures engine mounts, wheels, brake disks and cylinders and much more.
||Pedal close up
The wheels are made of 15X600X6 tires mounted on 600X6 wheels (manufactured by
Claude Guilbeault). While Angelo decided to use the smaller diameter
tires, he wanted forks that would accomodate the larger 600X6 tires.
His forks are made of 3/8" thick 6061-T6 flat bars.
