Most racing wings are thin in section and slender (thin) in chord, it lowers drag and helps them go faster, an easy formula, to go slower, go the other direction.

Trainers have big wings, wide wing span, deep in chord (measured from leading edge to trailing edge) and almost always thick wings. Increasing the wing span and deepening the chord (increasing the distance from the leading edge to the trailing edge) lowers the wing loading, and increases the drag, thickening the airfoil also increases lift and drag, both desirable properties in that situation.

Increasing the wing span also has the benefit of making the plane less responsive on the roll (longitudinal) axis, another desirable trait for a trainer.

It will have a 6" wing cord,
90" wing span
and 30" fuse.

Noob with 1185mm wingspan


Built a noob with an 1185mm wingspan. Using an old 800kv motor with 10x5 prop. It's underpowered but floats around nicely.

Thanks CF, it's a very gentle and stable flyer at the moment. I'm waiting on a 2200kv motor from Hobbyking, it should make the plane a little more exciting!

Here is a flight video of my twin engined 'bomber'.

jeez, those wings look like they are really bending! Is there a spare in there?

It has a bamboo spar with dihedral, maybe that's why it looks like it's bending? Wing is actually quite rigid.

oh ok. In the video it looks like the wings are about to snap on some of those passes!

Just curious, that looks like an athletic field, lots of lighting, longer than an American football field, just curious what kind of athletic field it is? Soccer? Polo?

That's great man! I do love twins. Let me know if you want to try getting you some Readi-Board. I believe I found a way to get a box of 50 sheets shipped from LA for under US$100, and the boards would be $55. If you're interested we would just need to explore the details and to find someone who lives in LA to go to Dollar Tree in Torrance, CA, buy the box, and drive it 4 miles to the shipping place.
