    RE: Lightning Build

    One note on the plans files I have sent out, I used a Staples upload program to create the PDFs. I have come to find out they put some kind of security code on the file so it can only be printed at a Staples store. No big deal for the guys in the States, but I don't know about the guys over seas. Do you have Staples stores? If not I will have to use another method to make PDFs for you guys as you won't be able to print them.

    As I understand it, and I'm apt to be wrong, it has to be external. New rule for this year IIRC.

    Tim
    No rule for it being external, the next WC will force you to have the transmitter on prior to connecting the battery, but it can be inside the model.

    Jeff, fantastic work! I am hoping to see it and you in Muncie

    Jeff,

    You said that you drew the airplane up in CAD, do you have a CAD file for it?

    RE: Lightning Build

    I made fiberglass tubes to line the holes for the canopy screws. I came up with a new method to make the tubes easier to remove after they cure. I slipped a piece of un-shrunk heat shrink tubing over a piece of brass tube. I then wrapped the heat shrink in fiberglass and soaked it with resin. Once cured, I slid the brass tube out of the heat shrink. I then used my heat gun to shrink the heat shrink, which shriveled up and came right out of my new fiberglass tube. Small lengths of fiberglass tube were glued in around the screw holes, and once cured, sanded to shape.

    RE: Lightning Build

    I'm thinking a small "donut" in the top of the opening to keep the screws from falling out when everyone you hand the canopy to turns it over to look at the inside of it.

    RE: Lightning Build

    What a great idea for making fibreglass tubes, thanks!
    To stop your screws falling out of an upturned cover, I have used small "O" rings on the screw, on the outside of the cover.

    RE: Lightning Build

    Any particular reason you decided to use screws for your canopy instead of hatch latches or rare earth magnets?

    RE: Lightning Build

    Doug,

    I have used this method for a long time with much success, so I have stuck with it. I do think there are some nice latches out there now, maybe on the next airplane.

    I have created more fiberglass dust tonight that a man needs in a lifetime! I have the paint and the primer on hand and hope to have a painted fuselage before I go back to work on Tuesday.

    if you simply put a few coats of wax on the tube, then heat it up to 120 degrees F during the lamination, keep it hot until it is cured... once it cools down, the tube shrinks (coefficient of thermal expansion thing) and then is easily removed...

    I would suggest an alu rod as a better mold/mandrel though...
