Make tail fin, skis, pulleys and motor stick assembly, pulleys are made with a balsa core of 2 balsa disks per each pulley, 1 is 1/16" balsa and 1 is 1/32" balsa of the proper DIA shown on plans, the pulley faces are made out of 0.10 plastic styrene sheet 1/16" larger in DIA than the pulley cores. Each pulley core is faced with very fine sandpaper before pulley faces are glued on, bore of pulleys is 1/16" DIA and a 1/16" DIA aluminum tube is glued into the center of each pulley.

Ok guy's here we go, I have already built my model to check the plans and parts, just a little tweaking on the plans and I will have them posted on Monday, I will be flight testing this weekend.
I built this model in 3 days so it is as simple as I can get it, very basic structure, just two pulleys to make is the hardest things to make on this and they are really not that hard. I printed all the coloring and markings on tissue with my printer and attacked to model, no painting or shinking of tissue. Here are my construction pictures, rotor DIA is 16 inches. I start off with building two side frames.

Lots of viruses going around...take care of yourself.  We can get to the cookup whenever you are able to get back to it.  No pressure!!!

Sorry Guy's been sick for the last 5 days and haven't been able to get these plans on disk yet, going to try and get out Friday to do them. FYI.

Cheers, Ray K.

I love the Comet Sikorsky R6, but it does not lend itself to my modest engineering to figure out how to make it fly.

A very interesting concept Strat-o, I don't know if I would want to tackle this one but it does look interesting, I have used pulley drives before and they do work well but you have to be able to get at the belts without to much difficulty. Plans for the 500 are complete I just have to get them on disk and we can start building, should have them posted here on Monday.

Cheers, Ray K.
