Getting back into control line and looking for a good transition into stunt, I came across the Hobo (Model Aviation Aug 2012) .  I wasn't prepared to drop $150 on a kit, and it looks similar to a Tower Uproar kit I've got.  Hmmm.

So here starts the bash of an Uproar into what I'll call my Misfit.  The Uproar is boxy and gives me a starting point with a fair supply of wood…
Oh, and this will be electric powered.

Since the Uproar's dimensions  aren't suited for stunt (stubby), I started measuring some other CL stunt plans that I'd collected to see how I would modify the wing and tail to set the aspect ratio and tail moment. The goal is to use the wing as-is, changing only the flaps and tips.  I also referenced Wild Bill Netzeband's "A SUMMARY OF AERODYNAMIC AND GEOMETRIC DATA FOR 101 C/L PRECISION AEROBATIC OR STUNT DESIGNS, ACTIVE BETWEEN 1946 AND 1996" which seems to be an excellent design tool.

Using SolidWorks, I overlaid a simple sketch on top of an Uproar scan and started adding tips, reducing flaps, and moving the tail around until the dimensions and factors fit within many of the averages that Wild Bill summarized.  SolidWorks can take a simple sketch and provide a quick surface area, so coming up with "K" (Tail Volume Coefficient) was quick.  My "K" comes smack dab in the middle of Wild Bill's average.

Next came the chore of figuring out how to modify the Uproar into a Misfit.

The first bashing step was to figure out how to fit and mount the ePower systems up front.
Using a pdf of the plan (amazing how accurately a scanned pdf can be used to measure parts!), I modeled the fuselage and key formers.

I wanted a way to insert batteries (yellow) without taking too much apart, so this tray will fit just above the wing LE, and the battery will butt up against the spar with the center wing sheeting cut away. 

A big ol' carved canopy will snap down with rare earth magnets to cover the hatch.  The Hubin Timer (green) was positioned to access the programming port (top connector).  The "start" button will mount towards the bottom.  The Ice Lite 75 (not the 50 I first posted) is in pink.

Started piecing things together.  I fitted up the bellcrank mounts between the existing R1's.  Odd shapes, but it fits between the ribs and clears the ball link.
Basic wing assembly is started.

First attempt at a magnetic building board - I like it!

I suppose it depends on how sensitive you want it to be, but I'd think about moving the bellcrank to flap control horn in a bit closer to the pivot.

Looks like a fun project.

Keith,
Looks good. I have a copy of Solid Works but haven't had the time to get into it. 

Thanks for the free publicity for the "Hobo". As you know, I encourage kit bashing and I show either internal or exterior controls, but I recommend the external controls because it makes changing controls ratios simple.

Keeping your concept in mind, I kept the elevator external, and I'll have access to the bellcrank and flap through the top of the fuselage.  The canopy will be removable, and I'll have a cut-out above the flap horn. 

Those fat tips with the hinge wire captured ...

 Hinge wire? In the wingtip?

Hinge wire? In the wingtip?

Yeah - poor description there, I know.
The hinges are all pinned with one wire running the length of the flap.  The wire exits the wing tip at which point it's bent back into a hook and pushed back into the tip to hold it in place.

Beautiful CAD work! ...and with color and texture.

My dream is a vintage Drafting machine and table with a drawer full of accessories.

I'm such a Luddite, I could never keep up. 

 

Finally finished
Took it out for maiden flights today.  While the motor power is perfect for 5.2 sec laps, there was some trimming to be done with tip weights, line rake and such. 

I think I'll keep it...

When I get it trimmed out right, I'll spend some time on a cowl and an actual color scheme.

Steve - it came out 3 lb 10 oz (58 oz) with battery installed.  The fuselage sides and ribs are heavy.  The wing loading came out just under 13 oz/sq ft which falls in between my Cardinal (11.9) and my Tutor II (15.5).  I'm happy with it.
