The retracts are brilliant, proving to be as reliable as Behotec's. We fitted a set of Behotec C-36/2 in one of the prototypes, but the mounting has been changed to suit Ripmax's gear. You will have to pack quite a bit. No the Nano legs won't fit and are not up to the job anyway with 4mm pins. You could have Airtech Germany legs machined to fit, but the gear will cost a lot more and honestly, I'd stick with the stock gear, it works perfectly and holds air for ages.

A few pictures of the Xcalibur I have just assembled.
As yet unflown, the model is powered by a Wren 100 and uses Hitec HV metal geared digi's all round.
With a 3300mA 2S ECU lipo and 2 x 1800mA 2S Rx lipo's, the model needs 300g's of church roof in the nose.
Looking forward to test flying it before handing it back to the owner.

Chaps, pictures below are big, so click on top pictures for quicker viewing......Don't know how to delete big images??

You can almost certainly remove some of the weight once flown. We have been shifting the weight back on both Paul's and the Ripmax demo model. I think Paul has now removed 60 grams. I found Ripmax's model was in front of the manual balance when I first got it, I shifted it back to match, but more flying has shown it can go back a little more.

Would you say that rather than adding 300g's as required to achieve balance as per instructions, I could comfortably ad less.....Say 200g's?
Is the recommended C of G as conservative as, say a BV's Bobcat recommended c of g?
Maybe you would advise set up as per instructions and "adjust to taste"?

I have taken 80grams from mine so far, take off runs are shorter now, could go more, have to see next time out.. started with CG at 170mm, not sure how far it is now will measure next time..

Dave Wilshere

How accurate was you balance check? I'd say add enough to get it 1/4" behind the manual position and then experiment. Everyone likes something different on how neutral an aircraft handles.

Any update on when the US kits will start showing up?

We got one in Jose's hand now. He is putting it together.

The first batch for US was destined to finish at the factory at the end of this month and will take a ride on whatever container my other business have right after. Mike

Just got back from doing the maiden and two further flights with the Xcalibur.

I set the c of g 10mm behind that shown in the manual and found the model well behaved with the recommended control throw set up. Next time out, I will reduce the aileron expo from 20% to 10% (personal preference) and move the c of g back a further 5-10mm, as I found I needed approx 1/4 of down stick to maintain inverted (again, personal preference). However, the manual recommended set up makes for a VERY well behaved model.

The Wren 100 gave very good take off and vertical performance. First flight with good use of throttle, left me with the fuel level approx.10mm below the fuel bung, having landed after 6 minutes. The following two flights left me with approx. 15mm in the bottom of the tank, using high throttle settings for about half of the flight, then landing after 7 minutes.

This model has a very good speed range.....Full throttle for two circuits saw the Xcalibur going slightly quicker than my Supersport powered Elan and full flap/crow with the engine at idle got the plane to hover in a 17mph headwind. In fact, carefull use of throttle and elevator, with full flap and 8mm of crow got the plane moving backwards very slightly!!

An ideal first jet with a great speed range and good grass/short field capabilities (uses 1/2 of our 100m grass field). Quick to put together (I did 4 days and 8 evenings of assembly time) and an easy to follow manual. I think there are going to be a lot of these showing up at small clubs over the next 18 months!

Goodo, balance is personal preference, I like a little down load inverted as I find it smooths things out. Ailerons are not twitchy, so reducing the expo to suit is normal.

If anyone wants a complete Excaliber (from the first batch arriving soon) at the introductory price (1200.00), give Kwang Ko (authorized US dealer - Virginia) a call 703-664-2016. I ordered the military scheme, 12-12-13 & I believe he has 2 more kits to part with. I'm not sure what schemes they are.

Thanks

Hi Ian,
Well done on your maiden. I would like to one day own an Xcalibur, (I've wrote to Santa ) it looks ideal for my first jet. I have watched your video and all I can say is, I would be more than happy to land it as well as that first time out considering what my nerves would be like.

Will the next batch be ready for Christmas I wonder ?

It's a great model and well suited and priced to a newcomer to RC jets. It's also well suited to the average club field.

I fly many different jets from our field and was surprised how much the Xcalibur floats on, which is why my first landing in the video was aborted. The second approach was still a little too fast, so I pushed it onto the ground instead of going round again, as I was unsure of fuel left. As it turns out, I could have easily done a number of aborted landings as I had nearly 1/2 a tankfull left!

Ian,
I'm in the market for new transmitter, what do you use or advise me to look for with the Xcalibur in mind? I have no loyalty to any particular brand as I will be keeping my old transmitter for use with older planes/Rx's. I know I have asked this question of others but it all helps me with my decision making.

Cheers, Nev.

You could easily set up the Xcalibur with a 7 channel set, using separate aileron channels and a mix with down elevator for wheel brakes (using the gear servo to over travel and operate the brake valve). I set up my old BVM Composite Bobcat in this way with a Spektrum DX7.
However, a 9 channel set makes set up easier giving the option to put the nose steering on a separate channel and the wheel brakes also on a separate channel.
I use my trusty old JR DSX-9 which I find easy to set up, but I guess all makes/models are easy to use once you are familiar with the menu structure.
I do feel that putting the ailerons on 2 separate channels is usefull, as a "crow" mix with flap works very well with this plane.
Ian

Dave Wilshere

Ripmax's demo model that started this thread has a 7 channel Rx and two valves for the gear/brakes. I'm not a fan of Y leads on main controls, but this model has a lot of flying now and its been faultless.
Nev you can buy some of the new DMSS radios with an extra free 8 channel Rx. If you don't need the extra Rx you can even move on the spare and get some of your money back!
I'm looking forward to adding some CROW to my example, the Xcalibur is very clean (hence it flies so well on low power) So any added drag is a benefit. But with the flap near 90 degrees I have no problems landing it on our short grass strip, Paul's is the same, no CROW.

Hey Paul,
Do you have any other number to contact Kwang Ko? I have been trying to call for several days and it is always busy. I would like to see if he still has any unspoken for kits available. Thanks Jon
