3D/Pattern Design .46 Sized Foamie
Hi all,
Designing a .40 sized foamie 3D/Pattern plane based off the looks of the Seduction Freestyle/WildStyle.
Anyone have some good measurements on the tail span/chord area to include rudder, horz stab, and elevator??
Also tail moment length would be nice too....just to see how far off the ball I am....
I'll post plans and pics of construction on my web site as I go....

Any inputs would be greatly appriciated.
Even if you have a good flying pattern/3D plane feel free to post what you got....wing area, sweeps, chords, etc... it's all good.
Thanks!

RE: 3D/Pattern Design Questions
From what I've seen if you want a dual purpose plane the wing design is the main
concern. The constant chord wing does not work well for pattern. A pattern like wing
with larger ailerons and large elevators and rudder is what you will probably need.

RE: 3D/Pattern Design Questions
Tommy,
I agree, the wing design is a BIG factor in having a plane that will do well in BOTH 3D and Pattern.
I'm primarily a 3D pilot, so I'm coming from the fun-fly direction...
I've had such a great success in my ultra-simple diamond cut airfoils on the larger planes that I want to try this (unusual) approach on a .40 sized plane.
I've heard (and saw video) the Seductions are awesome at both.
My key approach here is an ULTRA SIMPLE, Fast building, low wing loading airplane, using Pink Foam and hardwood rails for support ONLY in areas where needed.
Here's what I've got so far.... (so far just top view)
48 inch span
48 inch length
4 inch wide ailerons and elevator
6 inch rudder
1.5 inch max thickness of wing
17.5 inch root chord
12 inch tip chord
708 sq inches of area on main wing
26 inch horz stab span
Engine mounts on 3/8 inch hardwood rails that run down the side of the 1.5 inch fuse...also acts as a support for mounting wing and stab to...
Wing location MAY move to accomidate CG without adding any extra weight.
I was hoping for a 48x48 (1:1) ratio type plane much like the guys do with the 2 meter planes...
I'm planning on being able to start construction and finish (flight ready) in less than 5hrs build time.....and with less than 20 bux worth of materials in the airframe (minus engine/radio/hardware).
With horz stab area comes out to 955 sq inches of total wing area - at 5 lbs (expected max weight) - that's 12 oz sq ft loading (can you say floater, heheh)...
SO....what ya'll think???
Are we having fun yet??
