Yes, I really like that scheme and regretted instantly the moment you posted the photo of her. But at least I get to see her here

Default Hopper tank

Has anyone used the stock header tank that came with the PNP?

It's a well used CARF item and I have seen quite a few used in Germany (Where I guess they can be bothered to assemble them!) Better than some of the after market units sold today...

99% of jets built use off the shelf units, I use nothing but the MAP Canada bubble traps as I feel they are the best on the market. Many people buy on appearance! Strange choice in my opinion for such an important element in our jets.

I think the importance is it should at least have a sock (or felt) over the mesh filter inside the UAT and the seals that seals the UAT do not fail prematurely causing a leak of fuel (and air).

A pick up with surface area is the most important thing in a hopper tank, so felt and sintered cylinders don’t really cut it in this case. I’ve seen both blocked almost completely.
Joints is another thing, the multi-part machined body versions are full of joints, so lots of potential leaks from the assembly and fittings.

Good morning.

@Dave - good point!

Dear guys, any input of weight of your beloved Joker for reference?

Mine weighs 7.425kg dry with batteries and 9.1kg fuel UAT and main tank with KT K85G turbine.

Have a great day ahead!

Default Tail pipe and turbine going in

Installed the tailpipe and turbine tonight Went ahead and did a heat shield above the pipe. Adds no weight. Raised the turbine 1/4 inch as previous pictures showed. Needs it to center the turbine. Thanks for the heads up.

Default Joker

Another thing I found tonight 3 cuts in the nose gear wires. It was neatly stored and tie wrapped Going to have to completely replace that wire. No I did not cut them. It was a bread tie.
Also I had to make my own carbon fiber bell mounts even though the instructions say they are included

Hi everyone, Iím looking at buying a Joker, I have an Xcalibur at the moment and Iím wondering to keep it and save up for a while to get a joker as well, or just sell the Xcalibur and take the Rx and Wren 100 out of it. Iím just thinking when the weather is right and I take the jet I donít want the Xcalibur to just sit at home (canít fit two jets in the work van) Iv been told this is a great follow on jet from the Xcalibur, what do people think, just sell the Xcalibur to fund the joker or keep it and wait till I can afford both?
Thansk for any inputs, Tom.

The Joker is perfect as a follow on. If you have got everything out of the Xcalibur as far as learning, the Joker will take you to the next stage.

Hi Tom

IMO keep the Excalibur and save up for a Joker. If you start selling the old planes definitely itís gonna be a ďlostĒ because of the high depreciation.

But if you have 2 jets, you can regulate both on alternate flight days and if one engine goes for routine service, you still have one to keep flying.

Default Joker


How does this not burn the airframe being push up so high making full contact with the top of the fuselage?

That's the idea of the 'cool' wall. The outer tube has air moving between it and the tailpipe the whole time the turbine runs, so the outer Alloy tube does not get so hot as to cause an issue

Kekelala that does make good sense to be fair, but Iv just got a funny feeling that when I get a chance to go flying I think il be taking the Joker with the other prop models. Dave I think your right mate. Il wait until Iv got ďboredĒ of the Xcalibur and then sell it and buy a joker, the Xcalibur is a fantastic model. But looking forward to getting something a little faster and more sport ďscaleĒ looking. This thread is great for my confidence to buy a joker. They look ace. And yet seem nicely dosile to land.

The Joker is my first turbine jet. I am coming from edf jets. I am buddy boxing with an experienced turbine pilot. From my experiences thus far the Joker is a smooth flying airframe. The Joker tracks straight down the runway on takeoff and the recommended cg seems to be working for me. When I did the cg I put some fuel in the main tank. when flying inverted I do use a little down elevator. Landing is something I have very little experience with on the Joker. I have 16 flights on the Joker thus far and have landed it the last four flights. The first one I was terrified and wonder how it even happened (blessed). My friend/instructor claims I did not inform him before making the landing so I guess I got away with one. The last three landings my friend/instructor talked me through and those landings were some of the best I ever had with any airplane. I still have quite a ways to go because when I am not being talked through the landings I still have some issues.

I say all this to make the point that the Joker has been a great first turbine aircraft thus far so I don't see why it would not be an even better second turbine aircraft.

It is a decal and it won’t be clear coated. Warm it and it should peel off...
