About this Plan
Direct submission to Outerzone.
Quote: "G'day Steve and Mary. Given the interest in the vacuum table article, then I offer you a useful gadget that I designed a few years ago. I suspect that this might get the download counter clicking over.
Although it looks simple it is deadly accurate - a friend who flies precision aerobatics remarked that it picked up a few degrees of discrepancies with his aileron and elevator servo's (one to each surface).
This shall probably be its primary use and it is also useful for people who program multiple rates into their transmitters and want to test the results

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsJust to keep things cheap, instead of Turbocad, google for Librecad (it's free)

Also QCAD is free, I've tried installing and using that.

Free this, free that! Oh, the cheapskatery! The space probes NASA sent to infinity and beyond would have to be Kinder Surprise Egg trinkets, no? :))

True modelers don't have much money, thus they build, and have to find ways and improvise with what they have (e.g. McGyver), so yeah, a lot of "cheapskatery" goes on in this magnificent hobby. BTW... not to be confused with cheapsteakery, which is the art of hopping from one restaurant to the next in search of a cheap steak (modelers are known to practice this a lot too).

My version of TurboCad was free, it came with an electronics magazine a few years ago (I like cheap). Use any simple CAD program you wish, it is the principle that I was trying to impart.
My friend uses a Deflectometer to set up his multi-servo wings and dual rates etc. and he commented that it can pick the difference between two (supposedly) identical servos.

Before I get the rotten vegetables treatment, For many years I used Draftsight from Dassault Syst. (yes, the same Dassault!) which was free, but I had to give it up when it went to 'paid'. It now starts at 300€.
Then some 5 years ago I was in need of a true 3D package, and what I bought lightened me at 995€. Since then I missed some chance of an upgrade, my version ceased having support, and the new version is another 995!€, so thank you very much :(
Now, before I get entirely sidetracked, the deflectometer is a fine invention, thank you, Danny! It should work nicely as a warpdetector too :)

Attached 2 photos [pics 003, 004] for the Deflectometer (oz14953) also a short video, see https://www.youtube.com/shorts/3huGDT17vb8. Thanks to Dave for this nice tool idea. For building the tool I needed less than 1 hour. Regards from Germany,

Thank you Juergen, your video shows what I was trying to teach to aeromodellers that something simple can be very effective. I am glad that you liked my device.

* 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.
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.
