I went with the conventional high wing.
I am aware that some say the low wing will launch higher but it is my first DLG so I wanted to get the wing as far from the ground as possible when I make a hash of a landing.
I am 6'3" and pretty lanky so doubt I will be struggling for launch height.
I also got the carbon D-box wing for some added stiffnes and bling factor.
It is not common knowledge but he also does a ballast system for it. I got that too for the windier days or maybe a spot of light sloping.
I also got the carbon fuse with 2.4 friendly Kevlar nose and left that all unpainted. Seems bonkers to me to paint carbon!!

Bring on the 28th of March!

I covered the flap hinge gap with 10mil mylar and it works perfectly, flexing upward when the flaps reflex fully upward with the ailerons and laying flat otherwise. I found the mylar on a 3-ring notebook cover (transparent) at Staples. Just cut 1" strips and LIGHTLY glue them about 1/2" from the edge of the gap. Leave 1/4" unglued in front of the gap to allow flex. It works quite well.

If this is your first DLG build I would look at the DVDs from Radio Carbon Arts on building DLGs. I have 3 of them and got so much out of then. The TS2 was first REAL DLG build and it wouldn't have turned out half as good as it did if not for the info I got from the DVDs. On the first test glide with a gentle hand toss the plane flow away dead strait and level with NO TRIM needed and landed 40 yards away. This was first time I ever maidened a pane that didn't even need one clik of trim. I have taken the tips from these DVDs and use them in all builds now, even if it's a sport plane, 3D, giant gasser or whatever.

Yep, ihave been looking at them and almost ordered one last weekend. People seem to think they are worth the cash and your testimony sounds compelling.

Anyone got a used DLG building one they want to sell? I spent all my cash on the DLG!!!

c/g

Maybe i missed it, but did any of you have to add tail weight to get the plane to balance at the 70mm from leading edge balance point? I added approx. an 1/2 oz to balance with a 1300mah battery.

Most people have a CG around 77mm back from the edge unless they move the battery forward a lot out of the compartment. That's a good location for a lot of people, though.

My manual notes the c/g at 70mm from leading edge...so you are indicating that the balance point it is back further, but then slide the battery forward to compensate...sounds strange or am i missing someting? Where did the 77mm come from?

The February Radian Pro Big Sky contest has concluded and the top times were impressive.

The March Big Sky is open but this month we welcome the Original Radian pilots to the party. Let the soaring begin

Putting the battery in the battery compartment doesn't provide the manual's recommended 70 mm CG location for most people; it makes the real CG more like 77mm. To get 70mm you would need to move the battery forward, almost all the way out of the battery compartment. You would need to measure yours to see if this is true for you also, and experiment to see what CG you prefer. A lot of people like the further-back CG.

As for adding weight too the tail at 70mm ,thats a first ive heard of someone having to do that at the 70mm. From what i had to do at 70mm was add weight too the Nose,and thats with the Battery 80% out of holding area...
Either something Seriously wrong with your Pro or something..Is there a oz of glue on your nose or something? lol
At 70mm, where is your Battery located to? All the ways in the hole,50% out etc...?

Quick question... I'm building up a Radian Pro from parts... I received everything today BUT the carbon fiber spar!!! I figured it would be with the wing set Horizon does not list the spar as a separate piece.

Anyway, I need a spar... is there anything special about the spar? any reason I can't go to my local kite shop(he sells us airplane guys carbon fiber out of the back door) and buy a 10mm tube? It looks to be nothing more than a straight tube in the manual.

I'm going to call horizon and ask about the spar in the morning but I don't think they will have me one by the weekend... if I can just go buy a 10mm tube I can fly it this weekend

Shultz,
Why would you build one up from parts rather than just buying one? Just curious.

Guys, should we tell Shultz the secret about the spar tube?

I have heard that getting this spar tube has been a problem. See if you can get an arrow shaft. Should be long enough and would probably be stronger than the Radian spar.
