Thank you for this opportunity, Jürgen.
And also a big Thank you top FMT – VTH GmbH magazine.

These kits will only be available to folks living in the USA.
Others will be able to get a kit from VTH Magazine starting next month.

I will post to my Web pages yet this AM.

Work is slow especially today as it is -21 C [ -6 F ] here just now :-(
These temps are just not normal for Indiana.

So, I've moved
I am using the Foam2foam glue from Delux in the UK.


If I am very lucky I may be able to maiden yet this weekend at our local
indoor fly Sat evening.

Best

Looks good Bob,

Nice job on the CNC parts, seems they fit well.

For Depron and other foam I prefer the UHU-Por glue. In case that it works like a contact cement, wrong glued parts can be easily removed when you apply some cleaning solvent with a small brush. The glue can also be thinned with the solvent, when it has to be applied to bigger aerias like the two parts of the KFm wing. To prevent parts from sticking, just lay a piece of bakingpaper between the parts.

I found a distributor in the US, take a look at the reviews too.

Jürgen , Thanks for the UHU-por link.

It's from a full sheet of 1000mmx/700mm/3mm white depron.

Thanks again Jurgen

I haven't tried UHU glue yet. Nothing beats the instant set up of foam safe CA when kicker is applied!

I have been using Loctite Crafters glue from Hobby Lobby. With the 40% off coupon, it's about $2.40 for 2 ounces. It works great on any type of foam and doesn't give off harmfull fumes. It does take a while to set up.

I can´t agree! My experience with CA on Depron is, that it makes a glassy connection.
It´s not felxible any more and loses crash resistance.
I also don´t like Uhu-Por any more (sold also as UHU Creativ if I remember correctly)
Problem that I have with UHU-Por that it is not UV resitant. It gets yellow/brown and loses adhesive force.

Normally I use PU glue (also Gorilla Glue) and a little bit Epoxy

Wooo WHoo
I just finished cutting packing and shipping my 1st LISA to Washington State..
Thanks again Jurgen.

It doesn't belong here, however, Jurgen shared another design with me and I
have just cut it also. It's called a Judi SeaJet .
I especially like the Coast Guard theme.
Vid is here ...
FMT Heft 07/2014 - Judi Seajet - kostenloser Downloadplan (3 min 45 sec)


Cuttings pix below :-)

It is a Flying Wing type for water or slide on ground operation.
I am showing the Cut sheet and boxing.

In case Jurgen has retired for the evening,
My opinion is that you would have to modify the wing and add some dihedral
to make it a , 3 channel, RET, machine.

It is currently a FLAT wing with a single CF spar plus KF foil doubling.

Thanks for the answer Bob,

I agree, with the flat wing LISA is not designed to fly without aileron.
I think you have to add 4-5 degrees of dehadral on each side and build the wing in two halfes.

Jürgen ...

You have done an outstanding design job with your LISA and Judi SeaJet builds. They are beautiful to watch as they move so smoothly through the air. And, one of the secrets of a good video is to keep the plane in close to the camera so you can see it.

Wonderful work.

Thanks Dick,

I´m pleased you like the planes.
A friend of mine shot the videos and edited, it`s a second hobby for him and he always gives tipps to pilots, how they have to fly:-)
