Bad Day....not happy!
For the past two days, I've been building an all foam plane. Tail group was 2 mm coroplast. I've got 1" thick 4x8' sheet of blue
foam and some 1/4" fan fold foam. So, I glued two pieces of
1" thick foam together for a fuse. Put the tail group on, dug pockets in foam for 2 HS-81 servos and 555 rx. Speed 400 in front. Made a 36" wing from the fan fold stuff. Chord of 6".
Wing is cool, I put a 1/2" foam spar in and folded the fan fold panels over. Its a nice symetrical wing shape. I go outside and
tape an 8 cell battery to the bottom of fuse to check CG and test glide. 1st throw, plane glides down and left side of wing hits ground. Fuse breaks in half where I cut out the rudder pocket.
Scratch 1st fuse. I put wing on another fuse I made a few months ago. Tail group on this one is paperbacked foam glued in.
1st toss, glides down and hits wing. Fuse breaks in front of tail
group. I'm 0 for 2!!! I'm afraid to go to the bathroom now!!!

One thing with this pink/blue foam from trial and error. Tape it, this stuff can take some abuse taped up but untaped it just snappes like a frogleg under a semi truck tire, tape it likt a t-52 and it should work a lot better.

Last summer I started several foam planes using 1/2 styrofoam and 1/4 " Bluecor all seemed to disintegrate during test glides. adding balsa and tape did not make things any better.
Had sucess with wings from a toy foam glider "Flying Eagle"
and a Corroplast fuselage, and a Bluecor tail. Plane flys, although a little stiff. It is VERY crash resistant....
here are some pictures and instructions
I have since started playing with conversion of white foam gliders to RC planes. Working on conversion of a Life-like Ultra flyer still a work in progress. will post pictures when complete.
Have set up a Yahoo group to discuss ideas and have library files, Photos and links for members. Come join us.

Carl, thanx for the info. Adding the site to my favorites.
Dauntae, yeah, I should've taped her up. 1st fuse broke right
where I had the top pocket dug out for the rudder servo. Apparently, that was a weak area. Hehe, you only learn thru mistakes. I also have a new idea. Had some 3/4" pvc pipe that you use for hot/cold water. Cut a 22" piece off and was suprised it only weighed 3.4 oz. I might have to make the "fat stik"!
I got enough fan fold stuff to make over a dozen planes. May take me that many to actually get one to fly!

Dave you have got to do the fat stick, This I want to see. I love this hobby, there is always something new and often amusing to do.
