Cool
Concept Xtreme 2

Well, the twins are here! Now I am REALLY excited.

I received notice on Tuesday that Roland was shipping my gliders and they arrived on Thursday.

The shipping box is double wall all around and very stout. Critical parts were wrapped in bubble wrap and the whole box was filled with foam peanuts. All parts arrived in perfect condition.

On close inspection I was stunned at the extremely high level of completeness. This has to be the most ARF DLG available. It is more of an assembly than a build. The craftsmanship is outstanding, easily on par with the best I have seen.

The parts kit includes a 4.8V, 400 MAH 4 x 2/3 AAA, Ni-Mh battery and two 7 gram digital servos for the rudder and elevator. The servos seem to be high quality and are free of slop. A throwing peg is included. Roland even included an embroidered Concept hat!

Ailerons are driven by RDS with digital servos installed in the mold. All control surfaces including the elevator and rudder are gap sealed at the factory.

The vertical tail came assembled to the fuselage boom and the rudder horn and push rod are installed.

The elevator horn is pre installed and so is the push rod.

Rudder and elevator are driven by a double bell crank system that is hidden in the stab pylon. Pull-Pull strings are installed and strung to the nose area. All of this is done at the factory.

For the tail surfaces, all there is left to do is mount the stab, glue the included servo tray into the pod area, mount the servos and attach the pull-pull strings.

The canopy is held in place by the usual carbon rod which comes pre installed.

A nice touch is the full sized drawing of the tip area with dimensions to aid in the install of the throwing peg.

I am a slow builder but I should easily be able to finish and fly one this weekend.

Dan, I'm envious. I wasn't feeling quite as bold, so I only ordered one - But it'll be months before I see it.

Even though the build looks simple, please post some pics...

Yeah, I jumped in early. As soon as I flew Mike's I knew I wanted one, so I bought two!

I may be incorrect in my assessment, but this is what I know of the issue.

In talking with George Morris, I gathered that the issue was bad CF fabric that Roland had gotten. IIRC, these first few planes were built just after his shop was destroyed by a typhoon. He had to resupply all his materials in a hurry, and thought that the CF he had gotten was not of the same quality he was using prior to the typhoon. After hearing of the issues, he went to a different cloth that had already proven itself.

Again, I could be wrong, so don't take that as gospel.

Yes, that about sums it up. After the JEM Roland did tests and found problems with the fabric he was using for the booms. He has since switched to another fabric and test results were very positive. Outside of Mike's and George's gliders no other bad booms were shipped.

According to Roland - "Stiffness has increased by little over 40% and buckling strength by little under 300%!!!! The weight is just 1g more".

I can verify that the booms are VERY stiff. I flew #1 CX2 this morning and I am very happy! Thank you Roland!!

I will post some more pics later.

Dan
