I went with the Hanson UAT It's exactly like the BVM one. Just 25 dollars cheaper. Always worked perfect for me.

Hi Sailfish,

Many thanks for your feedback and pictures.
Looks like you also used a non standard UAT, rather then the supplied one...



Regards,

Eric

Manual says 8mm up crow at the root. That would be measured at the flap right? It doesn't seem like much crow. But if you do 8mm up at the outboard side of the aileron it makes it about 15 mm up at the flap. So which is correct Also, what has everyone found to be the best throws? And what does everyone's weigh in at? Mine comes in at 17lbs 9 Oz with all batteries and UAT full. That's quite a bit more than the 14 lbs it claims. Thanks!

I don’t use any CROW, with the JetCat low idle thrust it’s not needed, but you should not use much as it removes so much lift.
measured at the root is how it’s meant.

Gear is in the same on the std kit and I have not touched mine, I presumed because it is installed it’s ready.

Hi Guys, Iím proud to say Iv brought a second hand Joker with a Wren 70 :-) :-) it will be interesting to see what the Wren 70 is like on our grass field but first flights will be taken off at RAF Coningsby so no worries about runways lengths to start with. My question is iív only got a DX9 so i will have to Y lead at least one set of controls, what would people say is the least risky option? I would prefer the elevators to stay separated just for redundancy. Would flaps be ok on a Y lead? I didnít have this issue with my Xcalibur.
Thanks Tom.

I always go with the flaps if I run out of channels on the RX.

You can’t Y lead without a reverser, so Powerbox Micro match or JR matchbox is best.

Thanks Dave, I think you know Jamie who I brought it off?

Iím not so nervous of flying it as just coming in on the landing circuit with the flaps down. The Xcalibur is so easy to fly/land hopefully this wonít be too much harder. Iíl order one of the above thanks.

Yes, guessed it was Jamie’s model. If you coped with the Xcalibur you have nothing to worry about. Just remember the down elevator needed with flap

Dave W, from Motors & Rotors flew his CARF Joker at the first JMA Meeting of the season over the weekend at the BMFA National Flying Centre, Buckminster Lodge.
This one is a Jetcat P-100 powered, with the PowerBox Core Radio System, the weather on the day was good, however the stiff breese did cause some local turbulance over the boundary approaches The Joker looked totally locked in, and very stable.
The landing gear on this Joker has probably seen more grass (sod) than hard runways, and has been totally reliable.
