First I want to thank all the great folks at Ezone!
Without the friendly helpful discussion group support there, this project would never exist and I'd still be in the dark about electric's ;)
Seasoned builder? By grabbing some numbers and glancing at some pics you should be able to get one in the air.
Intermediate builders will want to at least study some of the construction text and view the linked detailed pictures in more depth.
Beginning builders should read it all and study each picture up
close (click it) for the notes written on them.
Any construction methods that are new to you can be researched further in
most cases.
Try doing a search at Ezone for the subject of interest for starters.
Please read through all of the instructions before starting building.
This will give you a better overview to the entire project and may inspire
your own revisions to the construction.
It's better to understand what you'll be doing before you try to do it!
Tools: You could probably build a Wally with just a good pocket knife if you're an expert!
Most of us will want the usual assortment of building tools common around the shop.
Besides things like rulers, pencils, scissors, hobby knife, etc. you need the following:
* A straight, level, flat building surface (must have!)
* Band saw if available, a fine tooth wide blade hobby saw or hacksaw blade, or at least a serrated table knife.

but not required.
