Walt, You are welcome.

Wow that'll be a big LISA fer sure.
6mm I assume.

In reviewing the RClist forum in Germany I decided to study the Judi SeaJet 200% !!!

It will require 5 Full sheets of 6mm x1000mm x 700mm depron.
It'll be 47.4" span ( 1206mm spanwiet )

Pricing calculates to $69 plus shipping to anywhere in the USA.

Anyone interested just PM me.

I MAY HAVE to look at Double sizing the LISA too :-)

Jurgen:
What is the blue material you are using on your windshield?
Is it packing tape?

Walt,

it`s an adhesive film / cover, like it is used on balsawings.
Sometimes I use a kind of cover wich is used for advertising or lettering on cars / buses. I get this adhesive film as scrap material from a company wich makes this kind of lettering.

I have a question about the landing gear. Are you using styrene? If so, what are the diameters? I have no local source and I have never worked with it. I can order it online but since the rod has to fit into the tube, the dimensions are critical. If anyone here in the US has made the gear, could you give me a hint on sizes and sources. I know Tower Hobbies has styrene. Thanks.

The parts for the landinggear drawn in the plans are just pushrods.
As you can see in photo , the ones in the middle 3mm like this

the "claws" on the left are made from the smaller pushrod with a 0,8mm pianowire inside, like this

http://hobbyking.com/hobbyking/store..._1pc_bag_.html


on the right you can see how the parts are glued with cyano.


the axle ? is made from 2mm CFK rod

For the landing gear we use plastic pushrods .
The outer pushrod has a outer diameter of 3mm and 2mm on the inside.
The Inner Pushrod has a outer diameter of about 2mm
and a 0,8mm Steel rod is added in the Inner Pushrod.

Toby

P.S.: Jürgen was faster

Thanks. I was basing what I said on the pictures and couldn't really tell what was going on. Saw the drawings but my German is a little rusty.

My progress has been interrupted by several things.

Not the least of which is the discovery that the servos have the wrong connector
for the RX that I picked out.
I am also struggling with the LG material that needs bending.
I keep thinking that there has to be a Nifty/Trick solution .

I even tried to heat CF rod so that it could be "bent".
The thinking was that I could bend, hold and CA the bend angle.
Epoxy is just another melt able plastic after all.

Recall I also "worked up" a 200% version for CNC cutting.
Plus there have been numerous Huny DO's and lastly
I have to fill orders as they arrive.

Good thing I'm retired or I'd never get anything done.
