Fantastic to hear you are up and flying, guess we got to call
you captain lynx now. ;D
tracked down some foam board but wow, sort of expensive in
respect of the price you guys pay + I think it has a small
amount of clay in it so it is slightly heavier, Oh well I think
it will have to do. Going to order it soon.
If you want a slow plane check this guys plane out .....

That is incredibly slow. Love the video. The secret is wing
loading. 13 oz divided by @ 6 sqft is really low.
The TomKat I designed is about 6oz/sf which on the light side.
I once was flying in some wind and if I pointed into the wind
the plane would just hover and gain altitude. I had to turn to
lose altitude and then point back to wind or be blown off over a
neighborhood. This was a 6 minute flight that pretty much ended
where it started.
Thats a problem with light wing loading - you can get blown
around on even the calmest days.
6oz/sf is Ok if you have the power available to get through the
wind. Otherwise it is a very slow flyer.
Sorry you can't find the cheap foamboard. Regular foamboard is
Ok, but you may want to cut lightening holes in the fuselage and
look for other ways to build light. The planes I designed will
vary between 3-5 oz depending on what material you use. The
radio motor battery add 3.5 oz.

Retirement Speed.
Do you think I could attach a fishing line and lure and go
trolling with that?

I have been playing around with 2" thick Styrofoam and cutting
it into 5mm thick panels with a hotwire. It cuts great but boy
is it floppy so I tried white wood glue and brown packing paper
to laminate the panels to basically make my own foam board.
This works and makes for a strong but light panel but if you are
not careful they end up bent and twisted when dry. Tried
painting the foam with emulsion thinking this would create a
skin on both sides but this was a failure.
Any ideas anyone as I can get this foam very cheap ?.

@ Lynx
Many thanks for the offer, normally A1 size is the board to get
for most plans I have seen (24" x 33" ish).
I am just trying to do this as cheap as I can that's why I
mentioned the above idea !!, (I love cheap HA HA).
I can get A1 foam for about £35 for 10 sheets but as soon as I
mention that I live on a Island in Scotland they hit me with the
postage (This just sucks !!).
At the end of the day I think I will just end up getting some
anyway, It just hurts my pocket :'( :'(

I get you. I am racking my brain on what you might have and how
you can get around buying the right material. Trying to
laminate enough paper to be strong will not work well, it's just
too heavy. Foam is 97.5% air but quite strong. Put paper on
both sides and it is very strong.
Really the fun of these airplane models is how fast they are to
make from this material and hot melt glue.
Cheers

This video is where I got the inspiration from in which he
constructs a full plane from the cheap white package type epp.
Hopefully it will let you see my idea, This epp I can get
locally from the builders yard for about £10 for 8ft x 4ft x 2".

@ Lynx:-
Just been on your other site and love the "LazyDazy" plans,
Little confused with a few of the parts but I am sure when it is
cut out it will all fall into place.
Looks as though this plane will be very stable in the air and
sloowww. Great work and thanks. :)

Thanks,
It's really pretty simple once you cut the parts out. The plane
is so big that it takes the whole sheet so a lot of diagrams and
templates are set over wings. Download the TomKat plans and
there are four pages of step by step. I'll get the step by step
on its own file soon.
This plane has a very flat smooth glide and should have long
flight times.
Its interesting with its lifting stabilizer.
This evening I made a very simple wing incidence angle tool.
I'll post a video on how to use it. I almost finished up the
Macchi 5 seaplane. Its trickier but fun. All the controls are
in and it works well. Just need to water proof the bottom.
We're all in the kitchen visiting. Wife and daughter are
singing and playing games, me cutting and gluing. TGIF
