Simple airplane design
Many years ago RCM magizine had an artical "by who idk" but i dicuss the design parameters of a simple rc airplane. It included how to start with the wing deminsions. from there it told you how to come up with fuse, and tail deminsions. it also included a "cheat sheet pic" of a basic trainer. Anyone remember this? If so how can i get my hands on this info or does anyone can point me in the right direction to designing my own plane and hopefully be suscessfull the first time leaving the ground.

RE: Simple airplane design
That sounds like a Chuck Cunningham article. He wrote the same article half a dozen times. Pretty basic stuff from the 60's or 70's. His numbers were something like:
a wing with an aspect ratio of 5 or 6 to 1
Ailerons about 6% of the wing area
Fuselage length about 75% of the wingspan
Horizontal tail of 22-25% of the wing
Elevator about 20% of the horizontal
Vertical tail about a third the area of the horizontal
Rudder about 30% of the vertical
Balance at about 25%

Ailerons can be a large as 15% of total wing area on sport models. 3D-type models have all bets off.

RE: Simple airplane design
keep it simple-
- learn to balance it then go to next design
Here is the GOOD part
Once you figure out why this goofy design works -you will understand the basics of stability

RE: Simple airplane design
I remeber the Chuck Cunningham article. He took about 3-4 articles to give you all the info on designing your own airplane. When Chuck was through then Ken Willard came right behind him and with one simple article gave you all the parameters for simple model design. I liked the Ken Willard approuch myself.

RE: Simple airplane design
Don't fall in love with your prototypes and spend a lot of time on finish - they're just a tool to figure out what changes you'll be making in the next version.
