Jim,

I went out to the shop and looked at the can to be sure. Its the surfacing primer. Your choice of color. Im using the grey.

On a side note. I used the Clear High Gloss Coating a few times. Once on a P4show plane for a dealer. It had obechi wings that were glassed with .75 oz and epoxy. Then sprayed with the clear and sanded and polished to a mirror finish. Found out that this stuff is used for car and airplane wood interior details. Fantistic product.

Duratec.

Dave,

Sorry to bother you with more Duratec enquires. I am near the stage where I have to make a decision to use it and so order some if I do.
The supplier here in this country will only supply me with 1 gallon amounts. Also, they advise that I must buy the catalyst separately and that comes in 500ml containers! Nothing smaller. Also, I will need thinners as per advice.
Questions for you:

1. What catalyst ratios do you mix for this product? I'm assuming it's 2% like polyester resin.
2. What thinner ratio for spraying though a 2.5mm nozzle? (which I don't have yet).

Since I have to buy such a large amount and that I have to buy a new gun with a suitable tip to spray it (The largest I have is a 1.5mm tipped gun), the whole project is sounding like it's too expensive and wastefull for the number of moulding jobs I do. Also, short shelf life etc.

Sadly, I might have to go back to automotive systems for priming surfacing my plugs.

Jim.

Jim,

I mix the catalyst by eye. No real measuring or ratios, treat it just like using polyester resin.

As a thinner, I have tried all the required medium, Lacquer Thinner and MEK but I still prefer Acetone.

I have used my regular tip for spraying with no problems. Just thin it down.

I don't know what to tell you other than its great stuff and saves a lot of time. But a gallon is really too much and it will go off on you.

Good luck on your project!

Dave

Thanks for all that Dave. This is the killer! I was really looking forward to using it too!

Jim.

edit:
I can buy small quantities (any amount I want) of polyester spray gel coat at a local composites workshop. I might have to go that way. Have you had any experience using this?

Jim,

Same thing holds true to GelCoat. You have to Thin it down to spray through a standard tip. Make sure you add Surfacing Agent to it so you can sand it.

That would be "wax in styrene" I understand. Is that correct?

Yep. Paraffin Wax desolved in Styrene. Any supply house will have it or you can make it your self by shredding some wax in styrene.
We do it for surfboard production using a cheese grater. One bar of Paraffin to one gallon of Styrene.
What this does is create a barrier on top of the Gelcoat so the stuff goes hard. Otherwise it stays tacky just like laminating resin. The reason it is hard and shiny out of a mold is that no air reaches the surface against the mold. The outside surface remains tacky for good bonding by the glass being applied to it.
I know you know this Jim, just info for those that don't know about this procedure.

If for whatever reason you can't get Surfacing agent, I have had pretty good results spraying a thick layer of PVA over the Gelcoat which provides the barrier against the oxygen. Once cured you rinse the PVA off and you can start sanding.

Wax in Styrene.

No Problems for me getting it Dave. My local friendly fibreglass shop has it ready made.
At this stage, I think I will go with the polyester gel coat. I'll thin it and try spraying it out of my 1.5mm tipped gun. It will involve more sanding which I do wet, but I don't really mind that. Lots of builders complain about a bit of sanding!

Thanks for all your assistance with making these decisions again Dave!

Jim.

As long as I'm first, it's not an issue. Heck, I'll be happy to be on the waiting list.

Hi Guys,

The Ghost is a reality, finally! I have been working on the fuse layups and am getting close to having a final product.

I have pulled a test wing to check the mold but this is not a flying wing, just test halves.
I have carbon on order right now and will be making prototypes for our crew here in Hawaii for testing.
Glidermang will be testing an early version for me in his conditions and putting it through his test program.

Once this is wrapped up and sorry I don't have a final time for deliveries yet, but its going to happen very soon.

When I have a flying model, I will post photos here for you.

Price range will be $650 - $800 depending on the carbon selected.

I will talk to my Web Master and have him set up a new order form which will just be a list of those interested in a Ghost.

Check in here for where to go to be on the list. No details on the plane or options yet. There's no commitment for you by being on the list. It will just hold a place for you and we will work out the details when its time.

Thanks,

Dave

Its been awhile so here are some photos of last weekends maiden of the Ghost.

To keep it short, the prototype is heavy as expected at 11.5 0z. Which is one ounce over the typical Legend.

Could not make any real assessment on performance as the conditions were turbulent with lots of lift and sink.

Problems with the wing fluttering on hard launch which I know the reason for. But I can say it goes fast, slow and climbs like crazy.

New wing is already in the mold with mods to solve the flutter and get rid of some extra weight.

Testing continues,

Dave
