Is a 5 or 6 inch chord to small for an 80 inch wingspan? All but the last ten inches will be supported with CF arrow shafts. Looking to reduce drag with a thinner Wing on a twin boom set up similar to the ozone.

As promised, the maiden video of the 58" Bi-plane.

Sorry about the lighting conditions, but it is what I had to work with.

Also wondering if anyone has tip for mounting the wings in a mid wing configuration?

I use a single 2200mah 3s, can fly for 6 minutes and still have 11.1v left.

This is how I've been attaching my wings. High, mid or low, doesn't matter. Use magnets or just tape to keep them on, but this way they are easily removable for transport.

Basically, I create a short section of airfoil that just fits inside the wing. I then slot that section into the fuselage. Make sure the mounting section is wide enough to extend out an inch or two from the fuse so you can attach the wings to it. Of course, glue that sucker in place.

rcnewbieoz,
Any dimensions for the tail feathers for the Red Baron to match the wing. Plans (hand-sketch of dims) would be good as it is by far the best proportioned looking plane I have seen for a while and with your excellent finish looks superb. Tempted to get out the Depron straight away"

Sorry there are no printed plans but I think if you watch the videos carefully you will be able to tell the most important parts and dimensions. If you have specific questions please post here or send me a message.

The flat bottom of the wing is about 7 or 8 inches (18-20cm) for a 30" (76cm) wing.

What is a "Plank"?


I came into the aeroplane scene after an initial year in helis. Some of the heli guys refer disparagingly to "planks", which I took to be a general slur against RC aeroplanes, basically a form of intramural chaffing.

Now I've been reading here about "planks" being twitchier and more challenging to fly than other aeroplanes.

What defines a "plank"? No dihedral? Low mount? Something about wing surface area? No fuselage / minimal fuselage -- no tail structure / minimal tail structure?

I sense a gap here in my knowledge that I ought to fix.

Thanks!

syz, I think it's mainly wing sweep angle, or lack thereof.

Ed,
Thanks for the excellent schooling with the Armin Wing construction. I will be putting your lessons to the test tonight and can't wait for my color packing tape to arrive. I found a nice item that will probably serve two purposes in my shop that I thought I would share with you. I like the gift card tool for working the tape on the Armin Wing, but found something a little more rigid at Lowe's or Home Depot. Formica sample pieces seem very nice for this, but can also serve as the base plate for the motor mount on your aircraft. They are free and just a bit thicker than your typical credit card or gift card. You had mentioned there being several options and thought I would at least share that one with you.
