high-lift camera foamie...

rjarois · Oct 25, 2009, 06:30 PM

fellas, after giving my magpie-ap to a friend so he can learn to fly, i decided to build a new camera model. i did a google search for high-lift cargo airfoils...and this was listed as one of them. the fuse was cut out on the phlatprinter, and the wing test cut on my hotwire. it is a 10 1/2 constant root, and will cut it with a 55in wing span. the fuse is scaled to a magpie size wise. randy.

I believe this wing profile would not be stable. You have to pepare for nervous response for h-stab. It would be nice to test it though.
Good luck
Regards

This is a perfectly normal airfoil for stable slow flight and should not present any problems. don't hesitate to use it.
It's amazing what totally hybridized concoctions of single surface airfoils are being used to good effect.
This section should not any present problems as long as you have a light wing loading and fly slowly.

yea john, its worth giving a try... i got the model in the Clark-y programmed on both machines, so if it don't work i can just cut the other..i made a 40in wing span with the Clark-y thats proven. here is a link if your interested. randy.

Yes this looks good

look forward to seeing the rest of it come together

There's no reason it would make the plane unstable, but it will probably make the plane tougher than most to trim.

Interesting thread about the airfoil issue:

If trying an undercambered is important for you, please consider modern airfoils like the DAE31 and the DAE51. I used both of them on my last plane and was very pleased with their general behavior.

just a little more work, and i will test the heavy cargo wing....its a 62in span. i am hoping it can lift the small camera i have. randy,

realtimerecon · Oct 29, 2009, 02:48 PM

Should be able 2 lift more than a small cam !...RTR

rjarois · Oct 29, 2009, 03:22 PM

im just hoping it will lift it...

A little H.Z.S.cub (ALL stock) will lift a 6 oz. camera.And that wing is only 7"X47".So you'll have no problems...RTR

A "small cam?" That wing will probably lift 5 small cams. lol.
Good luck.

rjarois · Oct 30, 2009, 07:14 AM

yea, its a old canon G-7 that weighs 12oz. without battery.....thats my concern...maybe its not a small camera....randy.

Yea, 3/4 of a lb isn't real tiny haha. I always thought my Kodak 7630 was big. it's like 1/2 the weight of your cam. lol.

I think the wing will lift it... I would've thought a longer chord though... definitely keep us posted!

rjarois · Oct 30, 2009, 09:10 AM

fitted the wing to fuse...as of now the model is almost 18oz. i suppose the gear is next....any and all input is very welcomed. randy.
