Quote: " Many years ago, I drew up some plans using paper, pencil, and ruler for my Big Double Trouble (images attached). You can read more about this and my original scratch build on my website at:
https://balsaandglass.com/Balsa_Builds.html#BDT
As I had stated in my original scratch build description: “With my hand drawn plans, I don't have a pdf file that you can download. Sorry. Maybe someday I'll get the plans scanned into a pdf file, or maybe even try and work the plans up in a CAD program.”
Well, that time has come. I have finally converted all my hand drawn plans into a set of digital files using a very nice 2D CAD program called “Back To The Drawing Board” see: https://drawingboardapp.com/. I incorporated the various changes I made to my hand drawn plans during my scratch build of the model. I even added a new plan sheet with all the modifications needed for an Electric Powered Version.
In addition to the model images, am also providing you my original “Double Trouble Build Description”, a zip file that contains all my plan files in PDF format, and another zip file that contains all the plan files in DXF format. Please use the files as you wish. I know you folks do GREAT work in providing lots of information to the modeling world.
All these files and more scratch build images and information are available on my website. I hope other scratch builders will use the plans to build a very unique RC model.
Respectfully,
Larry"

Notes
* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
Scaling
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
