Chris,

What do you think of this as a first "real" DLG?

http://www.rcgroups.com/forums/showthread.php?t=2106720

I'll probably also pick up a Libelle to get the hang of DLGs first.

I've moved away from the "warmliner" idea... might as well go big in both directions (DLG plus a hotliner).

That does look very interesting.

I just love the workmanship that goes into these DLG's they are a thing of beauty.

I like the fact that there are 3 wing choices

Two normal glass wings with different foils and then a pro wing with carbon d tube.

In reality with some colour ($15 dollar option per colour) and shipping your looking at just over $400 bucks.

Chris, could you give us some idea of what mid range electronics in a plane like this would cost?

Cheers

Wow, that's beautiful! :thumbup:

Ben, you typically need a couple of good micro digitals (same as you'd use for cyclic on a 325mm heli) for rudder and elevator, and some thinner servos for ailerons. The Hyperion DS-09 seems to be a popular choice there.

So I assume it is a good value?

Would it be okay to learn DLG? He says it is not for beginners. But I don't know if that means new to DLG or new to piloting in general. I can spot land 3D planes but I'm new to this energy management thing...

It's an excellent value, IMO. I know how much work goes into a plane like that.
As far as skills required, he mentioned the wing planform and stalling characteristics, so you will have to be a bit more aware of tip stalls and dropping a wing compared to a more "beginner friendly" design. I would certainly go for his "homebrew" airfoil version over the other.

For me it looks like the Arrow Sport he talks about here maybe worth waiting for
I'm sure it will be a little cheaper as well.

Yep, to be honest that's the one I'd want. I'm not a competitor, and much prefer something easier to fly than the razor's edge of performance.

So what exactly makes a DLG easier to fly vs high performance?

I know in the powered plane world if I had to do it over again I'd skip the high wing and sport planes and just go straight to 3D (with reduced rates) after some sim time.

In the DLG world, the airfoil and wing planform are the big things that affect the way it flies. Some airfoils have a very narrow "happy" speed range, and don't fly well outside that range. Also the wing planform can affect the docility (or lack of) during the stall.

What's the plus side of a competition foil? They must do it for a reason...
