Hello Jeff

Thank for your mail. Design and plans are awesome.
You're a real gentleman.

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 :)

Chad,

Looking forward to seeing your new airplane as well!

Jeff,

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

Viper Driver 05-07-2011 01:14 PM

RE: Lightning Build
 
I do, I drew it in TurboCad. PM your email address and I will send it to you.

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.

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.

great work man.
im studing plans before start to build it. For a lighter final weight, im considering make wings in structure instead foam, as the "old school".:D. what do you think about this?. aplause on first snap?:)

Viper Driver 05-16-2011 02:32 PM

RE: Lightning Build
 
It is funny you mention built up wings, as I am considering giving it a try on the next build. Good luck with the build!

Hows the sanding coming along?

I can hear the grumbling all the way to my house. :)

Bill I understand we'll get to meet in a month or so. Look forward to it.

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.

Doug Cronkhite 05-17-2011 08:27 PM

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

Viper Driver 05-18-2011 04:27 AM

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.

And i repeat... I hope those guys in FAI are looking over their shoulder

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.

Some pictures of the motor rear support, fiberglassing, and weights of the fuse, canopy, and rudder prior to glass.

Oh wow man, that thing is really looking beautiful!
I think I am hoping everything goes smooth as much asyouare, to get color on her before Tuesday!

Good luck with the painting!

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...
