Who makes the RTV you are using and where did you order it from? We have a TAP Plastics out here that has a couple different variations but none seems to work as well as expected. One takes forever to cure but holds up well and one cures quicker but gets very stiff and crumbly after a month or so.

Have you started on your blades yet?

Don,

Aero-Marine products out of San Diego. 1-877-342-8860

He makes very small quantities of epoxy and molding products. The small amounts make it possible to experiment with different processes. The products are superior and I have been happy with all of them. They are always willing to help if you have questions. The prices are great and shipping for me three days

I have laminated the blades and attached the leading edge 5/32 wire. I did put a small piece of Oz glass at the mounting hub for durability. I have not quite filled the leading edge, maybe today. They have a rough sand that is about it.
Gosh I hate to cover them in iron on film but the guys say you have too. I was also a little concerned about the ability for them to flex properly.

This is my first auto gyro and I intend to fly it so I'll trust what these guys are saying I sure don't want another wall hanging

Cheers,
Matt

I like to cut into the leading edge the thickness of the wire (5/32"). With a straight edge, slice the rotor for the length of the wire. I thin drill my hole for the wire to anchor down to and glue the rest. It makers for a nice leading edge.

Thanks Dave,

I watched the video and it was very helpful.
I am getting closer to mounting them on the Fiberglass plate does anyone have a better detail of how exactly to fasten them to the plate.
Or where to look it up

Thanks,
Matt

Thanks Matt. I'm very familiar with them. I've used many of their products and I buy my bulk fiberglass from them. I would recommend them for anyone buying bulk molding supplies.

Not the mounting hole. More like the hardware. Dave or Joe could you show me a close up picture of the mounting hardware?
Thanks,
Matt

Here is my slow progress of the Wright 975 Crankcase. 1/6 scale. I am still molding multiple cylinders in an attempt to make one cast of the front and one of the back of the entire engine We'll see

Cheers,
