A piece of that will make a lot of motor mounts! Bend an L shape, then cut it off with a hack saw, then drill the holes you need to fit your motor.

This isn't a real high stress application, so you don't really need to worry about exactly what kind or grade of aluminum it is, just make sure its thick enough not to flop around.

You could also use aluminum flashing, its pretty flimsy, but you could laminate 3 or 4 sheets together to get the stiffness you need. Those would be found in the roofing materials area.
I know this has been mentioned before, but for motor mounts I love the stimpson strong-tie angle brackets from Home Depot. click here Those ones will work fine, but my local HD has a version with gussets at the corner for extra rigidity. I have used them with 500w motors with no problems.

Maybe with less diheadral it would roll better. Of course it is a trainer, but it was a real struggle for it to roll without losing some altitude and seemed to take forever. When I rebuilt the Cub I put a wood spar in the wing so I could get rid of the wing braces...they seemed a little weak to me. So it would be a real problem to make the wing flatter.

Anyway after reading and seeing the videos about the Armin wing, I thought this would be a way to see if I can change the way my Tiger Cub flys with a different wing. The Armin is about the same profile as the standard Super Cub wing. The Super Cub has a 48" span with rounded tips and a 7" wide wing. The Armin wing I built is a 44" wing with square tips and a 7" wide wing with 2" ailerons added. The Armin has a arrow shaft for a spar and the wing weighs about 2 oz more than the standard Super Cub wing. I was hoping that it would weigh the same or even less. Maybe I used too much glue and tape. The Armin actually has a little more wing area, weighs more, and no wash out built into it....so???

I hope it will fly....or even fly better! What do you think the result of the new wing will have?

Here are some photos of the Tiger Cub with the standard wing and with the Armin wing:

ps even if the wing does not improve the flight of my Cub, it was fun and informing to build the Armin wing. I have been looking at the Noob Tube and it looks like maybe my next build. I will have to visit Dollar Tree next week for sure.
ExperamentalAir has sure done a great job with his designs and videos!!!
Hey High Flyin'

Did you ever fly this bird, how did it go? It's winter and I'm bored and I have a Super Cub that I was thinking about building an Armin wing for. I hadn't seen your post before and just stumbled on it today, would love to hear how this worked out for you.

Cheers,
Geoff

I will use a motor mount http://www.rcfoam.com/product_info.p...ceff77125f4b7e

Might either bolt or glue the mount on top of the wing.

More on Motor Mounts

In response to SyzygyQ and Nieder2, I have found two possibilities

First, is a sheet Metal Angle Bracket 40x50x50mm (1.5"x2"x2")which I bought from Bunnings in Australia (similar to Home Depot I think) a couple of weeks ago (planning ahead for my Axon build) - very similar to the Stimson Bracket suggested by Nieder2.
It may be very useful with the holes already, ready to mount those 2826 motors, it weighs 28grams.

Second is one I cut from a 50x50mm PVC Angle Moulding I had in my shed/hanger. I cut it to 50mm(2"). Its fairly stiff, so will not flex much and weighs in at only 8grams.

Great info on this thread - keep it up guys (and Ed of course)

Hope this might be helpful.
Geoff

The main thing I don't like about those angle brackets from the lumber yards is they are usually galvanized steel and extremely heavy, the ones I make out of aluminum weigh almost nothing.

speaking of mounts...

Since there have been some questions about motor mounts, I'll share my latest mount.
Local HD was out of Simpson Strong Ties part a21z - http://www.homedepot.com/buy/simpson...l#.UN-Zwm80V8E

so I got this one instead (RTU2)

I agree, I just buy a strip of aluminium similar in width the that steel bracket, cut of a required piece, drill it and bend it, hey presto! Thatīs what you do right?

Thing 2 bites the dust

Dr Seuss' Cat in the Hat story had two interesting creatures--Thing 1 and Thing 2. My thing 2 was a photon converted to twin motors. I used the hobbyking AX-2308n 1800kv bell motors with 7X6 GWS props. They came with stick mounts so I had to buy some 8mm radial mounts and then I drilled the mounts out to 9mm to fit the motors larger diameter (I could only find mounts in 8mm and 11mm--too large). The photon had flown before, but I felt it needed an upgrade to support a camera. I used simpson strong ties (A18) to make my wing mounts. These little motors only have about 326 grams of thrust each, but the plane took off like a scalded dog (and that was with a 3000mah 30C 11.1V batt in the nose). The only problem was the aileron locked up. I think I over stressed it, stripped the servo, and it rolled off the wing and headed for terra firma. No problem! I had secured the wing with 3m extreme grade two-sided tape. The nose actually hit first and crumpled a bit, but the wing just twisted off. Looks like everything survived, so it will live to fly another day (probably with a whole new fuse more like the axon. So much for 5 gram servos. I think I'll stick with 9 or 12 gram servos for future builds. I still have another photon with an exceed RC rocket 2215-1850kv and it continues to fly well. It also uses the simpson strong ties for motor mounts. My only problem with the ties is that it's easy to break small drill bits.

A short vid of my armin plank wing:
Tight turns with my $tree armin plank Petrel. (1 min 1 sec)

I should not have attempted the loop without more throttle. Stalled and lost control, flew into a thicket of trees off-camera.
