I have bought HK electric retracts before, and while they work, the metal used tends to be quite soft. This may mean real problems with a 8 kg jet. Personally, I would spend a bit more and get good quality right from the start. These are a example of retracts that are made here in Australia, that work really well.

So what's the secret, what am I missing??
I have had good success using a Dremel with a very small ball type burr fitted. Link.

You beat me to it Nev, I used exactly the same also. Here's a photo of the exact bit I used. Takes literally seconds to make the hole.

Great idea! I have one of those tips, I'll try the Dremel approach first rather than the buring torture treatment.......

Test flew another Xcalibur at my local club. JR DMSS and P-100Rx powered of course :-)
Just like all the others, brilliant.
Paul was out with his and another member Colin his-both P-60 powered.

At the JMA weekend Jet meeting new to Turbines Dave Batchelor brought his new Xcalibur, P-100Rx JR XG-11 package for me to test fly. Perfect first flight as expected now, especially with this package used by so many of my customers.
Its great when someone with zero jet experience or exposure assembles one of these and everything works perfectly

I have slowly been assembling my Xcalibur so as not to make mistakes, but I now find that I have made one. On one of the rudders I can only get about 35mm travel in one direction. If I set all the rudder throws to this figure will I have enough authority to fly safely, or do I need to cut off the offending rudder and re-hinge with more gap to allow the recommended throw.
Thanks
Alan

You don't need a lot of rudder to fly safely, so set both rudders to the same travel

Immense thanks go to Dave W for his great help and guidance during assembly, initial runs and for test flying the model for me last weekend. Thanks also to Paul for another faultless flight. i don't have my B yet so couldn't fly at the JMA event but looking forward to it soon!

Welcome to RCU and Jets! You did a great job of assembling the Xcalibur, no changes needed after the first 2 flights is great.

See you for your test at the weekend!

I am surprised that the JMA require a B certificate to fly jets when this is not required by the BMFA or was this just at this specific event

Its always been a JMA requirement, we operate on sensitive sites, military and private. We don't have time at each event to "vet" unknown flyers for an understanding of safety. Having a B gives us a clue that the individual has a minimal level understanding of safe operation.

Busy day at our local site, Dave had a full day, passing his B cert in the morning, having his first fly around at lunch time and completing two perfect complete flights by mid pm! Well done. Took to it really well, listened and learnt-perfect student :-)

There were three RAF and two Sport scheme Xcalibur's there flying today, three with iGyro1e units fitted on rudder. Choppy day today and wind from the "rough" direction, the gyro certainly smooths out the tail shimmy in these conditions.

Good day all round

Congratulations Dave B for passing your B cert today, I shouldn't imagine there's many pilots that pass their B cert and go on to fly a jet for the first time all in the same day. Enjoy.

Nev (of the very green variety)

It was a really good day today, except I kept forgetting which one was mine lol, well done Dave B for passing your B test, great result. Now your hooked and can attend all those JMA, Classic jet events just think how many new toys you could buy, it's very addictive.
I purchased one of the Igyro 1E and Dave W kindly set it up for me and for my colleague Roland, must admit for 62.00 it definitely makes a nice flying jet into a smooth flying jet, especially today as It was quite breezy and bumpy. On cross wind turns in breezy conditions mine would waggle, not much, but with the gyro none at all, well worth the money. Dave set it up on a slider switch from 0 to 100, I have mine at about 45% , I believe Roland's one is the same, so appears to be just under half of its full gain. I don't tend to fly much else lately as I turn up, bolt on wings, fuel, air and go fly. It's aerobatic, fast ,slow and fun.

Thanks guys, i had the best day! The Xcalibur is every bit as good as the previous 53 pages of this thread promised. Only job i have to do is to iron some tiny areas of the blue film back down.

First of all, I will start by apologising for the length of this post. I've had my Xcalibur since July of last year and I posted details of my build on here at the time. Almost a year later I've flown it a lot, and so I thought that some people considering buying an Xcalibur may be interested in what I think about it now.

I already had another sport jet, a Jet Legend Viper Jet, but I bought the Xcalibur just for those times when my wife was using our van and I had to make do with the tiny hatchback. The idea was to share the same turbine between the two models and my installations allowed for this. However, it has turned out that i've mostly been reaching for the Xcalibur due to it's sheer convenience. It's only really in the last few months, however, that I have really come to appreciate what makes this model so good.

Let me explain. At first I must admit to being a little underwhelmed by the way the Xcalibur flew; compared to the Viper and the CARF Classic Flash before that it didn't quite have that real jet groove I'd got used to. My jet flying had to that point been pretty unadventurous; lots of smooth lines and constant high speed. Because its a jet I initially flew the Xcalibur in exactly the same way and it didn't feel quite as locked in as the higher loaded, faster models. I also used to land the Xcaibur like the other models, in other words way too fast for it and more often than not ended up fighting to extricate myself from the bounce of death. But of course I was being a bit dumb. The fact that it has a scary, noisy turbine in the back made me overlook the fact that, compared to the Viper, its about 5lb lighter and has about 1 1/2 times as much wing area! As soon as Dave Wilshere flew mine at a JMA event and made it crawl past at an almost unbelievably slow speed the penny finally dropped.

Since then I've proven to myself that it was the model, and not just Dave's magic powers, that resulted in such a wide speed range and I finally get what this model is all about. Rather than always just carving my way through the sky at high speed I am really enjoying mixing that up with slow, tight moves, flicks, spins, stalls, etc and actually using the throttle properly! I just love crawling it past quietly with full flap and then opening the tap to full noise and pulling into a vertical climb, no momentum involved, just pure thrust, then off the power again for a stall turn at the top. In other words, this thing is just like any standard club sport model - just with a jet!

The reason I've been thinking about this is that I've decided that one small sport jet is enough for me so one must go. Looking at them side by side my initial reaction was that I would keep the Viper; I think it looks great and the Xcalibur, well, to my eyes looks somewhat less than great. But then I thought about flying them both. Don't get me wrong, the Viper is a real sweet flying model and it can impress the crowd down at my club, but I have to admit that compared to the Xcalibur it's just a bit one dimensional. It's the Xcalibur that makes me relax and grin, just like my old WOT4 did (another model with questionable looks) long after I'd moved on to supposedly 'better' models.

So, it's not going to make anyone at the jet meets drool with desire like the 6K composite models, but for real world, every day flying I think it's a real keeper.

I have finished my Xcalibur the UK Flag version with a Wren 100 in it. I kept as much forward as possible and have my UAT, 2 Nimh 5 cell 3300 receiver packs up front and also the 2 cell lipo for the turbine. To my surprise my model has balanced ok with no lead at all. Most on here seem to have had to add lead. I was wondering if anyone else got theirs to balance without any extra weight up front ?
