Otto - are those hinges just the standard plastic pin hinges? Did you just glue them to the foam surface or did you do some prep work? How do they hold up under hi loads?

The hinging technique I use on my big foamies works very very well but its a total pain-in-the-you know where to do.

These look like they could even be made removable if you wanted?

Yep, standard Dubro hinges with the holes. I make sure I get good glue flow through the holes and a layer of glue on top. Good for models under 2 pounds where depron is used. With the 1/2" foam insulation, I take two 2" pieces of 1/4"x1/2" balsa and install the hinge between the two pieces. I then notch the foam and epoxy the balsa to the foam. For high loads I put a strip of balsa along the whole edge.

i've been using 3m medical tape for hinging for about 3 years on everything from
small, fast wings to overpowered Strykers and never had an issue with it, so thats how i'm going to do it...simple to do, only 3 steps and your done. first you cut a 45 degree angle on the edge of the aileron, then place the aileron on top of the wing, run a piece of tape along the edge ,turn it over, run another piece of tape on the other side. Done!! just be sure the edges are clean, and you have a lightweight, strong hinge without any gaps, or glue gobs.

i enlarged the plans at staples, but the counter guy (kid) was not great at math and could not figure out how to get the plan sized print to the size i wanted (6 feet tall)
the best he could do was 25 inches tall, so i'm going to try another staples location, and hope i get someone who can get it enlarged to my instructions. on a lighter note, i was not charged for the copies they did make (3 of them), and the counter guy told me to take them anyway, or they were just going to throw them out as garbage.
so, tomorrow i'll just get these 25inch copies enlarged 288% and that should get me a
72 in. high model..who is teaching these kids??? geeze...

Flies around just like a good floating trainer. A full scale version flown at dusk would be quite entertaining. Given some of the "conspiracy theory" types of today, there would be a number of believers.

I can only speak to my experience with Take Out container foam, depron and R-Tech that I use on my big foamies. With depron I use the foam safe ca and am careful with the activator to use just a whif of fume to accelerate, not drops. With the R-Tech I use Gorilla glue, but this takes some time to master. What is HD white foam? I'm assuming the blue is blue core and I haven't visited a Lowes yet to educate myself.

Otto

The Home Depot white foam must be R-Tech??
Yeah, and the blue must be Blu-Cor?
Don't know anything about foam, methinks I will be getting
an education!!!!

Thanks

My bad.... since I started using the term HD Foam. I do suggest you use depron unless blu cor is the only available. Since I have no experience with blu-cor I can only comment on building with depron from a rigidity and structural design standpoint.

blu-cor is not as rigid, but way less expensive. depron is the ideal foam, but costly.
i tend to use blu-cor because it comes in 25 sheet batts for about $30 or so. they don't sell single sheets so you wind up with a load of it leftover from your original project!!
this build inspired me to resurrect and old favorite of mine, my Witch on a broom.
i'm putting in a new electric .46 equivalent sized motor, swinging a 12X6 prop it seems like the old girl will be making a comeback for Halloween this year !
she's pretty big, 4 feet tall and just shy of 5 feet long. She's also getting some erie green lights!!!

Hah! they are back... In the 50s, there were articles in Aeromodeller showing flying men, freeflight. Always wanted to build one, never got the chance. Another application (for those who build quickly) would be a flying witch....

OTTO!

Very nice video!!!!!!!!!!!!!!!!!!
What kind of foam did you use on this one?
I want to build one, but finding foam here is a problem.
I don't need a full bundle.
