CARF Joker build thread

Oh many thanks Dave!!!
Will use these settings for sure as a starting point.
10mm aileron up, and 11mm down....that’s opposite of what sounds logical, curious👍
Many thanks again for this information!!!
Kind Regards,
Eric

If you want it to roll axially, that’s what you need with a top hinge surface, the area reduces into the wing going down, so it needs more travel

I thought I had hit the 100 flights with my Joker a few weeks back, but having updated the software in my Core Tx I decided to do a learn RC again and looking at the statistics menu I noticed I’d only done 99! There are 104 runs on my P-100RX and just under 17hours. Although it’s windy here today friend Paul wanted to fly his Ultra Flash, both models are perfect for these conditions ( we were the only two out!)
Flights 100 and 101 done, cleaning up reminded me what a great all year around model this is, the sealed nose bay stops the muck getting into the radio.

It's great Dave!
I'm glad to know Joker flies great even in the wind😉
... what are those green, red, yellow spots around canopy front part?

Be a great jet for you 😉 In Red 👍
At our jet meetings we check failsafe operation, some events linkages etc. The dot says it’s been checked. I get around to cleaning them off when I remember

Another Swiss Joker for a local guy. P-100Rx power, MacGregor 2810 servos, PB Core Radio. I know there is another just being born in Italy too, welcome to the Joker club Denis!
#732
I'm very happy to enter the Joker club, red scheme for me! Model looks great, quality outstanding and I'm sure it will be a fantastic sport jet!
As always - thank you for your priceless support Dave! ✈🙂

What a Nice flight this is!!!!!
Mine is stby for his maiden flight, as our runway was revised over the winterperiod,
and the grass is still not 100%. Engine run was already done (K85G2), with no issues.
Expect maiden in a month from now. Must say that i’m quite nervous already☺️
Rgds,

Just completed and shipped another Joker. This one features Electron ER30 retracts and a very cool set of carbon inlets from Daniel Schubeler. Servos are MKS HV747’s all around. All up weight with a full UAT/empty main tank is 16.44 lbs. As for electronics I think we have pushed the envelope on what can be done with the Jeti system and the 3rd party components available for it. The setup uses a REX R12 receiver (paired in default mode) with a REX R900 setup as a backup and connected to the R12 via EX Bus. Power to the system is provided by a Pulse 2s LiPo pack via a Jeti MUI 30 connected to the MPX power input of the Digitech CRU. From there it goes through a Jeti switch to the R12’s MPX plug. The single 2s pack also powers the ECU for the Jets Munt M100. The R12 outputs EX Bus to a Digitech CTU which along with providing telemetry from the M100 (and G loading and baro pressure) also acts as a 2 port EX Bus expander. This expander feeds a bavarianDEMON Cortex Pro and a Digitech SB-EXT which in turn provides the EX Bus input to the Digitech SB-IAS and CRU. All of the above are directly configurable via the Jeti DS-24 transmitter. Pretty simple. 🙃

Thanks to Danny and the team at the Rocket Factory for another awesome setup and assembly. As I call it everything is on the "Bleeding Edge of Technology". Cant wait to see it in person. Will post my findings after maiden.
Thank you Danny....

Will the nose come off each flight to check the air trap isn’t taking air?
Where did it balance? The position goes forward with fuel in the main tank, you might find you need to add some tail weight when you fly it.

With a single 4400 2 cell lipo the balance was at 185 BLE. At refueling if immediate fuel goes to main tank there is no air trapped, With a single 4400 pack I should get a good four flights before the pack gets to 50%

Adding to David’s reply...The nose on this one is secured with (3) external M3 screws, one through each locating pin. Pretty quick and easy to remove for inspection/battery replacement. I wish the stock screws were more accessible. Yes, they can be reached with a long driver but I find it a bit of a pain, one of the two things (the other being small flaps) I dislike about the Joker. Maybe CARF will refresh the design some day. Or better yet.....Do a mini Bolt! That would be awesome!

Well... that’s a given. No need for him the state that
Actually I admire Dave’s commitment to light weight models. It is the right approach to building and something I keep an eye as well. It’s just that some want different things in their models. For example, this one originally had a Jet Central Lynx in the engine bay. This required that as much weight as possible go as forward as possible. This is why the UAT is located in the nose.

OK, don’t be scared to experiment with the balance, it moves during a flight and it took me a few flights to find the sweet spot on that and gyro set up.
i saw the nose pin clamps, I found the stock screws really easy to access as I took my nose off for every charge, the three packs are in the nose cone so I could take that to my charging station.
The small flaps are not an issue with turbines with a low idle thrust like my JetCat P-100. I’ve seen people with other brands of 100 struggle to slow down because of the high idle thrust-if they roll on the ground it’s high!
My battle with Danny’s builds make me so predictable I decided to say nothing 🙂 I get the enjoyment people gain from both doing a super neat install and owning such a thing to look at.
There will never be a mini Bolt, we are lucky the Joker exists, as cost to the manufacturer is way above the return on small moulded airframes.
I spend my life moaning about weight...this weighs 310kg and I keep telling them it needs to be lighter 🙂
