So sorry to hear about your g ma. Post a picture of her for sure and we'll have the next post and the video in memory of her. You and your family are in our prayers.

What was her age?

I'm going draw out the plans tonight,
I'm using $Tree foam boards.
I have to ask, with the KFM step, what is better, putting it on top or on bottom or both?
I have to find something here to use for a wing stiffener too,I think I got some old fishing poles here someplace that will be donated to the cause.

KFm wing step is best on the top. Fishing poles should work.

Can't wait to see it when finished!

GLue is drying on the fuselage now.
Its a little more time consuming when you have to loft everything by hand.
I hope I measured that right, the fuselage is asymmetrical, 2 1/2" wide by 3" tall. I might've screwed that up.

I've added my Google Sketchup of the design.

I hope my step isn't to high,
I ended up using a 1/8" x 1/4" piece of hardwood I had handy.
So the step is going to be about 1/4" high for 24" in the middle and then thickness of the foam board towards the ends.

Wing is glued and drying now. I'll get the tail done tomorrow and glued on, and control surfaces made up.
Monday I need to order some electrics.

Since this my first scratch built and foamie, tell me what is the best material for control surface hinges?
CRedit card?
Tape? (Kind?)
I use to use a fabic type hinge material on balsa planes years ago so I'm looking for suggestions.

I also need a reference for the size/type of motor everyone used.
One more....
Are you attaching the motor to foam or light ply firewall?

Hi Caish,

Sorry I haven't been home all day but good to see your post about building your Ellipso when I logged on.
Best hinge is blendum tape like you get at the Drug Store.
I make my control horns out of credit cards. I'll post a full size drawing of mine. Cut it out as a template and use a center punch to mark for your 1/16" drill bit. Hobby Shop control horns are fine as well.
The motor that most have used is the 2212-13. A 1000 kv motor attached to a plywood firewall. http://www.bphobbies.com/view.asp?id...7&pid=B1688512

Post a picture of your plane when you can, we would love to see it.

I'm not real happy with the outcome, but here is a picture.
The horizontal stab isn't level, at least the way its sitting.
But heres a picture of the thing so far.

I have the ailerons held in place for the picture with duct tape.

It will be interesting to watch it crash and burn the first launch.
But the wing did come out pretty good for hand lofting everything.
The step is maybe 5/16" and the rigidity feels good too.
I sanded the edges to give the wing an airfoil shape.
Stay Tuned for more later, I've got to order some parts.

Looking good. Nothing wrong with that. If it's light weight and strong it should fly well and after all thats the fun part of the hobby.

What type of foam are you using?
