Hello, I have decided to take a short turn and make the FREE drawings available first and then resume on the Model40 and 2Place Weedhopper™ Plans.

This site will be romoved and redirected to the new site in a week or two. All of the information will be made available on that site...

On the new site there will be Free B-Model and C-Model drawings available for download. Just need to finish the 3D Assembly of the C-Model to make sure all the part dimensions are corrected. Follow this link for more information...

Free Drawings Available Here


The Weedhopper™ has long been favored by ultralight enthusiasts for the many desirable characteristics of an affordable ultralight. Now with these plans you can build one for yourself at a fraction of the cost of purchasing a new one.

Listed below are some notable advantages of the Weedhopper™.

The Weedhopper™ is everything you want in a legal ultralight. It is a simple machine and that is one of the things everybody admires about this ultralight. If you follow these Weedhopper™ plans you will end up with a aircraft that will provide many hours of enjoyment at a price that is easy on the pocket.

These Weedhopper™ plans will only provide the details for building the airframe.They will include drawings for each individual Weedhopper™ part.

There are so many power plant options available that I will leave that decision up to the builder. The Weedhopper™ has been safely flown with anything from 27hp-50hp, even the 1/2 VW.

These Weedhopper™plans will include a blank mounting plate that will accept the bolt pattern for mounting the engine of your choice. I will add dimensional drawings, to this website, for the bolt patterns of various engines as I complete these drawings.

Weedhopper™ Assembly Plans

These plans were created using 3D parametric modeling. This allows each individual part to be drawn as a 3 dimensional part that can be inserted into an assembly. There are many advantages of working in 3D. When you take all the 3D parts and put them in an assembly you can visually verify everything fits as it should. This also allows for motion of the 3D assembly so you check for clearance issues as well as proper operation of the movable parts.

I also describe a very easy solution or how this problem can be resolved. Check it out HERE for a detailed description.
