Hi, I’m buliding my second Joker, the other one i had was sold a few days afetr I maiden it, this olane is a succes and fun to fly.
this time I got a red one and PNP, servos installed all the servo cables routes and great quality, fuel tanks ready cabin glas allready glued and a few new things like the new gear and brake controler the pipe support also included in this model the only thing you have to do is install the turbiene batteries switch and rx, you can have it ready in just one day if you hace the time...

Look What just landed on my building board
Picked up at the Prowing fair in Germany by a flying buddy of mine, Thanks Nokki and Melanie from Carf
Afther unpacking and inspecting the whole lot, again you realize why each time i unpack a model from Carf the Grin on my face goes beyond the moon.....
Just Excellent quality and completely-ness, Just Briljant!!!!
I got an K85 on order for it but after putting the whole lot on a scale i came to the following,
- Fuselage 1734
- Wing 1950
- Nose 160
- Stab 280
- Canopy 100
- gear controller and covers 120
- Included Hardware 255
- Tank 90
- Pipe 380
----------------------------------------------
Total weight 5069 Gr 5.069 KG
Hmmmmmm....
This make's me wonder if it wil stay under the 8.5 KG when fully ready and inc. full tank.....
So maybe go for the K100????
But this will add up the total weight with 500Gr, 0.5Kg according to KingTech specs, and fuel consumption will shoot up as well......
Saying all this, i think the K120 will come on the list then aswel, cause according to KingTech specs its just a Tat lighter, but then again a rise in fuel consumption, and will the airframe handle the load of a 120N??
Arrrggggg, what to do, cause i got to make an decision on the engine fast......
Please advise...
Cheers,
Ed
For what it's worth, I have about 70 flights on mine with a JetsMunt M100 xbl, plane is about 17 lbs dry. It's not a rocket by any stretch but more than fast enough in my opinion. I've maxed about 190 mph airspeed in level flight, but normally fly it much slower. The open intakes without ducts and a bypass generate a lot of drag and I believe limit the top end, but with a 100, vertical is virtually unlimited and I can get comfortable 7 min flights with enough fuel for a couple of go arounds. It's been a great flying plane for me, there's nothing within my flying capabilities that it won't do and it lands very easily and predictable.

Hi Dave,
Thanks for the heads up, are these a drop in Fit?
And (maybe stupid question) but any good?
Cause never heard of/or saw these servo's?
How's the centering and center hold on these?
Thanks,
Ed

Just a tiny file on the mounts. They seem to be good, better than Hitec, like Savox, but less expensive. We were selling them at JetPower last year, people like CARF and Sebart were buying them. Centering and holding power is good.
The Joker was built to a spec and weight, if you all want a speed machine with ducting buy its big brother the Ultra Flash. It flies perfectly like it is. 70-80 or 100 is fine, we have one with a Wren 70 and it comes off our 90m grass strip no problem.

Hi Dave,
Thanks for the heads up, i hear yah about the servo's.
I'll go with the K85, as you said, the Joker is not a speed machine, that's where the Flash is for ;-)

Today I maiden the my Joker assembled at the Rocket Factory (F1 Rocket).. The Jet is equipped as follows:
K120G2..
MKS 747 servos
CB200 with R3 and R900
Cortex Pro (Limited Edition RED)
Custom Kevlar fuel tank with FCT..uat
After a few clicks of up elevator and one click left aileron the Joker was flying on rails. In my opinion the amount of aileron is too much at 18mm... on a role it spins like a top...... Other than that all manual recommendations were perfect. I had increased full flaps to 90mm (due to K120) and the Joker comes in for landing very nicely. Due to its large inlets and drag it slows down as soon as you go to idle. After having 3 Ultra Flashes (M200) and one Spark (K70), the Joker can be called a "Mini Ultra Flash" or a "Super Spark".
I would like to thank Danny and the team at "Rocket Factory: for another successful speed jet for my fleet.
PS.... An upwind full throttle alarmed at 210 mph

Questions?
Hi Fellas,
i am about to buy one of these and have a couple questions.
1. K85 or k100? I know it’s draggy so don’t know if the extra power is worth the extra weight. Never going to be super fast anyway. I had an Ultra Flash with a k100 and was a great combo because it was light and still fast once on step but much cleaner airframe. So does the Joker need the 100 to overcome the drag?
2, I thought I saw on the website there is a bypass but it doesn’t have ducting. Is that right? I could make my own ducting to improve performance. Done it many times.
3. Anyone have one dress led up with graphics or trim? Schemes are pretty boring as they come so just curious to see what you guys have done to make them look cool.
Thanks!
Brian

In my opinion a 100 would be plenty, then again the previous post says 210 mph on a K120 so pick your poison I guess. My max has been 190 mph, with a M100xbl, I usually fly with max speeds about 170 or so.

Thabks for the reply. Yeah I certainly would not go above 100 but I am wondering if an 85 is enough. If the performance really doesn’t improve much from 85 to 100, I would rather just stay with an 85 and keep it light

Yes, photo on their website shows a bypass, but none is included. I've toyed with the idea of making ducts but that would also require a custom fuel tank(s) and just seemed like too much effort for another 20 mph or so.
I don't have a very fancy scheme, a few vendor decals, you can see in this video:

Hey guys, are you putting the batteries all the way up in the nose to CG or are you finding that not necessary? Also what battery sizes are you all using? I have to two 2s lipos 2100 mah for the receiver and one 2s lipo 2700 mah for the turbine. I hope to have the maiden done by the end of May if all goes well. After the maiden I will be using the Joker as my trainer jet and hopefully can get my waiver by end of summer. I was hoping I do not have to put the batteries all the way in the nose. I want to be able to charge them outside the aircraft. If they are all the way in the nose it will just be a hassle having to take the nose off to charge batteries.

Is there any one able to show some picture of how and where of the battery instal?
@ Dave, is there an other then the Stock Carf (lighter) pipe out there?
Started giving the woodwork on the inside some sealing/coating.
K85 is on it's way, i go for the "Light weight" version is suppose ....

Ed

Morning Dave, Early Bird
Jep, could had figure that one out my self i guess... (dummy me)
I went on this web site and indeed there is a pipe but the weight difference with the stock is only 40gr (including stock bell mouth witch goes on both)
Think this is worth spending the money??

Do i see ducting here......???
Maybe i'm mistaken or maybe there's something wrong with my eye's but this does looks like ducting....
And this is the old inspiration pipe.....
I guess i'm having a brain fart, but this also looks like ducting to me....
