Ripmax Xcalibur Sports jet

hi all
test flew Xcalibur #2 ( RAF) scheme , and flew completely different than my old one
trim was way off ( used all available elevator down trim) and the plane kept climbing
cg is at 160mm
right aileron trim was also way off - had aprox 3-5mm right aileron trim to try keep the plane flying level
all I can say is that maybe this specific plane flys different
don't get me wrong , the first plane I had flew like a dream , I needed to offset the motor a bit with down thrust to get it flying straight with full pwer , but at least the elevator trim was level and wings were level too
bit disappointed .. any ideas?

yesterday I added 2 washers under the front bolts that hold the elevator to the booms changing the elevator incidence and that made a huge difference
Can it be I received a dud kit with the incidence between wing and elevator way off ??
if anyone else had this would appreciate your feedback

We'll I made a set of new mounts and angled the turbine even more down thrust and that did not help much

I should like to get to some jet meets so I will have to pull my finger out and see what's on and where. I have only achieved my A certificate at the moment so it makes flying my jet (when it's finished) very limited but I do enjoy the sights and sounds of you skilled pilots putting your pride and joys through their paces.
Will we be seeing you at Greenacres this year?
Best Regards, Nev.

Nev,
Should be there if weather is okay. The Xcalibur jets fly really well from what I've seen, I'm sure you will love it when it's done. Get your B sorted, be good to see another jet jockey at the meetings.

Hi Simon, Yes that's me. I very much enjoyed watching you fly your jet at Greenacres and our chat afterwards. As you can see I've made a start putting my Xcalibur together (at last), it's been/is a massive learning curve for me coming from all electric but with the help of the forum I'm sure I will achieve my goal.

thought the same but that was checked and was ok.
Will check wing with incidence meter against stab and see where the difference is
in any case looks way off

To fly yes, visiting is possible as we want to encourage new members. talk to me in the week and we can sort something if you are interested. Membership for the next 12 months starts this coming Saturday, £40. You can bring your model along and have it looked at by people who really know their stuff, membership is not all about flying at events.

Hey guys, I had the fortune of picking one of these models up. It will be here Monday, I was curious to see what everyone is running for servos in their models. I'm considering running either a K-60 or K-80 in it as this is my first turbine model. Thanks!!

Most of the packages I have sold use JR 11kg servos JR8421/JR8411 and JR3401 SAV 1250 on rudder. Also sold Savox SH252's but any 10kg on main controls and midi 4.5kg plus on the rudders you can choose reliable servos of your choice

Our club is small and flies off grass...the excalibur is perfect. When i first moved to SC 4 yrs ago there was just 1 other jet flyer and he was not a member of our club. We now have 6 jet flyer s and another in the making. Not bad.

We are a big club (grown from a club of 40 to over 200 now) When I started flying jets there were 2 people flying turbine jets in this club, it grew with the technology, the early guys dragged Air cylinders 100 yards to fly JPX's, when JetCat started with a starter motor it all changed, we now have over 20 members flying jets and more taking it up all the time.

The Xcalibur is more than just a fun jet turbine model, last night I travelled to the east side of London to have dinner with a fellow Xcalibur owner Denis Ferrari from Italy. Denis visits the UK on work and said we should meet, his Xcalibur is due to fly this year (he needs to spend less time travelling to the UK :-) )
Really nice guy, thanks for dinner Denis! Another friendship launched by the power of this hobby
