Das Ugly Glider (oz13485)
About this Plan
Das Ugly Glider. Radio control powered glider, for electric.
Direct submission to Outerzone.
Quote: "Steve, Here are the drawings and printwood for "Das Ugly Glider", my take on a 60" powered glider, inspired by Phil Kraft's Ugly Stik. I wanted an easy-to-build mid sized glider that didn't require a tow, winch, or hi-start to fly, and since my favorite all time airplane is the Ugly Stik (I think I've built at least 6 of them), I decided to use that as my basis for design.
I also chose to use the "tab-in-slot" technique for assembly, and it paid off. This thing went together in no time.
So, in tribute to Mr. Kraft, I give you:
Das Ugly Glider
64 in tip to tip
Clark-YH airfoil (modified)
17gram metal gear digital servos
6-channel Spectrum receiver
2217-07 1200 kV motor (480 size)
8x4 folding prop
40 amp ESC
2200 mah 35C 3-cell
The assembly is pretty straight forward, though I leave it up to the builder to choose how to hinge the control surfaces, servo placement, shear webs, and spar joiners. I have my own way of doing things, but they may not fit another builders techniques. At any rate, it's just a Stik, albeit with the proportions and aspect ratio of an old school glider. Have fun,"

Quote: "Steve, She flew great, no thermals, it was cold (31F), wet, and no wind to speak of... but she's easy to fly. Now I just have to wait for summer. Here's a short flight video. Charlie"
Corrections?
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

Greetings from the Yukon. The DUG is a three sheet affair - sheet one has to be scaled up so that the 5'-4 3/8" dimension is to scale. The other major dimensions on sheet one will closely match their respective scaled dimensions. The trick here is to leave sheets two and three alone - I've only looked at the ribs so far and they will match what is shown on the resized sheet one - or close enough to build from.KW - 12/12/2021
Yes, I think that's just the way the drawing is. I mean sheet 1 is annotated 'Not To Scale'. So it's just a layout overview. Sheets 2 and 3 are annotated 'Scale 1:1' and these two give you all the parts to build the model, and they just slot together.

You are correct Steve.......sheet 1 is the 3-view/assembly/component drawing is not full scale. It was never meant to be. It's purpose is to describe the hardware I used, and to show the completed assembly. Sheets 2 and 3 are 1:1 and are used to cut the parts and build the model

Good morning, I built the DUG II again in an effort to reduce the wing loading to below 10 oz/sq ft by reducing the thickness of the ribs to 3/32 and the fuse to 1/8. AUW came in at a whopping 31 oz for a wing loading of 8.9 oz/sq ft. I also increased the number and size of the lightening holes in the fuse and feathers.
Here's a pic of the new one [pic 005].
Hope you and Mary are doing well. Take care,

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.
