Boy, those are some great looking models and a great field. Wish I could have experienced it in person. This is good inspiration for the winter building season!

Re: 1/20 EDF Buccaneer

Monz, I am interested in how you "size" your EDF models. I assume you start with the fans and all the associated gear on your workbench first, in a sense. So you have that weight you know you will have to lift plus the structure. So what is your thinking after that point?

Re: Building from 3 View Plans

For airfoils I was advised by the late Walt Mooney to keep your airfoils under 12% thickness and put the high point of the airfoil at the 33% of the chord point.
