Not normally a fan of manual valves as supplied with the package, but the demo model I have holds air for weeks and allows several cycles on a fill. When I build my model I'll use the supplied valves.

My Jet arrived today. Really happy with it and great service from Motors and Rotors. Thanks Dave.

Glad you are happy, so far we have shipped 10 kits and everyone has been very happy. The last few went out today and our last kit ships tomorrow, so then its just a waiting game for more. I'll be impatient as I've stuck my name down for the next batch :-)
Good news is I did have spare retracts sets in from Ripmax today, already people are asking about fitting them into other models!

I will use this combined retract brake valve,
The one from the kit I will use on my Carf Spitfire.

Dave,
How does the Xcalibur compare flight wise with a Boomerang Nano or Sprint?
Looks like Ripmax have taken a Boomerang and engineered out all the known faults and put the refinements it into a fairly priced package.

Because of the cleaner aerodynamics it holds momentum better, its between the Nano and Sprint on size, but flies with a P-60, which the Sprint would struggle with. It flies more like a Sprint than a Nano, Ali who did most of the Boomerang testing says its a step up on all of them. Its also a much better package than the Boomers, undercarriage designed to fit and proper instructions. There are three Xcalibur's in the Aberdeen club, you should be able to see one soon.

Started the build today. Retracts are fitted.
Mounting the P70 turbine was not the easiest, its pretty tight but after som cutting it went in. Will post some pictures tomorrow.
Battery, fuelpump and UAT will be mounted in the nose cone.

For sure, P-70 is about the largest turbine you can fit! You will need everything in the nose to minimise nose weight!

By the way. I measured the volume of the tank, about 3.15 liters.

Jamie sure you have something lying around!

P-100 is a good choice for future projects too.

Tank should be 2.9 ltrs!

It grew, originally it was about 2.5 ltrs. Either way as seen the P-60 version carries it fine.

Yep, will find something . . . . OS 91/Ramtec, BVM91/Viojett or BVM 96? or if i cannot fit those in, i may have to resort to a Jetjoe

I have not seen it yet, do not know if he ordered the retracts for it, Will take a look tomorrow. Will have to go in the queue after the Viggen.

Thanks for posting the photos Paul, and it's nice to hear of a build thread that appears to be straightforward and not fraught with problems, keep up the good work.

Looks like you are using the same air system for retracts and brakes. One fill valve for both retracts and brakes. It is generally wise to separate these 2 systems so that a leak in the brake system does not drain the more vital air for the retracts. Just an observation from many years doing jets

quick trip to Motors & Rotors this morning for a couple of servos for rudders and some extension leads.
Almost done, got the nose wheel closed loop done, run some leads, I like the tubes in the booms and wings, helps a lot getting the leads in good design feature.

Some pictures as promised. I have cut off aprox. 20 mm of the duct.
Most of my flying are at paved runways so I skip the FOD for now..

Looking for some help with retracts as im stuck with the plumbing. Nothing in manual to help me. Could someone maybe post a sketch so I can use it as a reference.

Thanks Jeremy

hope this helps just a quick sketch, add the brake line from each wheel,
then a T piece to join two lines, then only one has to go to front, you will end up with 4 lines, one gear up, one gear down, one brake and the last one to the fill valve and air tanks into the + piece.
