As you are suggesting Dave it's a perfect club model, packs into most cars,easy to assemble,both in the workshop and at the field, flies great on smaller turbines, and handles very well. What more could you want?

Units would fit, but legs won't. Its not worth looking away from the Ripmax set, its excellent. The P-80 won't fit. No turbine bigger than 100mm dia will

Ken hooked me up with the sports version of this model, looks like a pretty quick build. Got it all hinged up in just a few hours.

Is anyone actually using the horns supplied with the kit?

Have looked at horns a few times, but decided to go with stock horns and screws throughout, even with a P-100RX. Monitoring elevator horn for heat hardening, but so far after just 15 flights it looks and feels the same as when installed and I'm happy. Original model had lots of flying over 8 months and horns all still good, summer and winter flying!

Dave, You were right. I cut the wing tube too short and now it wont lock the wings in place. I need to remember the old adage....measure twice cut once... Do you have one in stock?

Hi Tom. We can help you get the tube. We are ordering some parts from factory. Did you talk to Jose about it? Mike.

Really couldnt get wing to fit at all before I cut it. Think the secret to success is to bevel the tube when I get a new one. Oh well.....live and learn. Thanks anyway!

Did you guys make sure the wing clamps were loose?
I assembled mine no problems not even much force, just a spray of silicone lubricant on the carbon tube and bam! This was from the Aussie batch tho

Still have the bit you cut off? Hysol it back on, You could add a balsa wood + inside to support, the clamp only retains the wing, flight load is inboard

One thing worth checking, the steering arm on the nose pin only has an M3 set screw holding it in position, I've seen two now where steering was becoming vague and it was this screw loosening. I loctited mine when I checked through the gear before installing-don't presume this is tight! .Its also worth checking the retract frame screws to ensure they are snug.

I have 4 flights on mine now, from our grass field. Flight time about 9-10 minutes whit 1/3 tank left on my P-70 turbine. I have moved the CG to 168mm.

Regards Daniel

Some interesting findings today with my build. The manual says mini servos for the rudders. One boom the mini servo kinda just fitted, there was almost not enough wood to screw them in straight down but on an angle it "just" worked.. The other boom the opening was way too big, so much so that a full sized servo fitted perfectly. I ripped the mini out of the first boom and made a full size fit.

I'm sure these small issues will get sorted in the next batches but regardless a full sized servo fits just fine.

Daniel.Great, I took mine out hoping for another 5 flight session, but I ended up club trouble shooter and only managed one on my model.

Yes, Ripmax and the factory are aware, we discussed it after the first batch came through with FS servo openings. This allowed midi servos to be mounted deeper with plywood inserts glued behind the installed plates. Light weight servos are better for balance.I used JR 3401 servos which are now much lower price in England.

The stock brakes are superb on this kit. I had another flight with the one I assembled for a clubmate and found I could hold the power of a Wren 100 up to 2/3 power. This caused the model to squat on the T/Link legs and give a cattapult type launch when released.
Significantly quicker than my P80se powered Elan with much better "get up and go". My Navy scheme Elan showed up better in today's overcast sky (Xcalibur is white/blue) and models have similar slow speed capabilities.
Both models very well suited to our 100m grass strip

Ian I play with the "launch" take off too, we have a ridge on our patch from an extension and I can get a 4m take off roll with the P-100 wound up to brake creep, a reasonable head wind and TO flap and the kick the ridge gives! My Xcalibur lands slower than any Elan I have flown...its a lot lighter and similar size.

Maybe i didn't try hard enough in slow flight with the Xcalibur.....mind you, its not mine to find the stall!
I'm sure there will be a few Xcalibur's at CJ's on Friday!
See you there

Stall when you get there is sudden,its why is flicks, snaps and flat spins so well, but landings hover in!

Tom. great.
