    RE: C-ARF Ultra Flash build Thread + Video

    Yeah I have a block under the plane to keep the stabs off the floor of the trailer. However in the mishap, thel live hinges on the stab and flap already delaminated and needed to be glued back so thy are extra strong now.

    Do you have a block under the tail? The elevator control horns can be touching and it will lift the hinge and tear the foam

    RE: C-ARF Ultra Flash build Thread + Video


    ORIGINAL: mtnflyer14

    Not to sound harsh, but there are 121 pages of posts here and the subject of flap deflection, crow/no crow has been discussed thoroughly. Probably best for you to wade through the posts instead of starting the discussion all over again. Basically, the manual CG is fine (look back a couple pages for Dave's picture of where he likes the CG) and crow/no crow will never be resolved - it's all pilot preference.
    Regards,
    Gus
    Yes, I would imagine this may have been discussed somewhere within the 120 previous pages and I really did not have the time to search through all of it to see if or maybe it was there and that is why I elected to put the post. Apparently, I don't have the endless hours to look up stuff on RCU like many others and I thought this was a UF friendly thread all about the UF but apparently I was wrong.

    RE: C-ARF Ultra Flash build Thread + Video

    I can see how you might feel that way but it's amazing what you can find out if you just use the "search this thread" option. . . .

    Words that will yield the answers you seek: CG, Flap settings, CROW etc. . . .

    RE: C-ARF Ultra Flash build Thread + Video

    I did not intend to offend you, but yes, this is a very UF friendly forum. You will find the jet community UF experts (I'm not one of them) following this thread. But, if every new UF owner asked the same questions, the thread would become repetitive and lose its vitality. So, I ask you to use "Search this thread" for CG where you will find 4 pages of posts and "Search this thread" for crow and you will find 5 pages of posts. Best of luck with your UF.

    RE: C-ARF Ultra Flash build Thread + Video

    Well 2 flights on the flash today in 20mph cross winds and it lands just fine. 3.5" flap and 3/16 crow was night and day over the 4" flap setup. Very predictable now.

    RE: C-ARF Ultra Flash build Thread + Video

    The guy I got it from drew black circles on the bottom. With mine on the balancer centered on those holes, it fell just s
    Ightlybowardsvthe nose. However it fell towards the canopy when inverted so its still nose heavy. Needs a TON on down elevator when you drop the flaps with these settings.

    RE: C-ARF Ultra Flash build Thread + Video

    Yep i backed off a little on my full flaps too...Same on the ultra lightning....Would come in with less throttle and was able to hold the nose off much better...My opinion its the best sport jet in its size class anywhere...

    Dave
    DW, it's beginning to look like the tide of popular opinion is decidedly swinging toward the use of crow

    It's not a night and day improvement like it is with the Classic but it's a definite improvement. Personally, I can see no good reason NOT to use it: the slight aileron uprig WILL further prevent tip stalls in the slow flight regime. That can only be a good thing.

    RE: C-ARF Ultra Flash build Thread + Video

    As the UF is such a popular model this topic on flap settings/crow etc is going to go on and on.

    I have found the UF the most pleasant of my jets to land so far.I have posted my settings on this thread before but here they are again and in my opinion are just perfect.

    All measurements at tip.

    Take off Flap 27mm ( - 1mm down elevator mix)
    Landing Flap 75mm ( -5mm down elevator mix)
    Crow on full FLap + 6mm
    + 1mm up trim on elevator for normal flight.
    CG 232mm from LE cut line (tanks empty,ATU full,wheels down)

    I found operating manual travel settings for aileron too powerfull so reduced to;

    Ailerons +9mm/-10mm (up/down) 40% expo.

    Rudder 45mm each way (40% expo)

    Elevator +10mm/-11mm (40% expo)

    If you go with these setting you cant go wrong and will have a very pleasant and easy model to fly.

    Phil.

    Tumbler:

    The center of that circle is at around 230mm from the wing's LE (fuse joint line) which is what I though you had. again, Thanks!

    Every one of these settings is within a gnat's ***** of where my Ultra currently flies. Wonderfully I might add.

    RE: C-ARF Ultra Flash build Thread + Video

    Just a small update after checking my 18MZ expo settings.

    On elevator I have reduced expo on take off flap to -25% and down to -20% on full flap as I find this gives a more linear feel to the elevator on final approach and flair.

    I use 3 flight conditions so this is very easy to do.

    RE: C-ARF Ultra Flash build Thread + Video

    Hi,

    So just to confirm, is everyone balancing with the model upright? I always balanced it upside down with the gear up. I was thinking of moving my cg back a bit but wanted to make sure were all on the same page as far as how were balancing it

    By the way, mine is balance in the same place as it was. So the landing characterics were only changed by by reducing flap and adding crow. Put 9 flights on it the past 2 days. I have some video I will post.

    Me too! 10 gallons burned through it and 14 flights. A couple quick clips off the Tv in the hotel. Will post some better video later. Fast pass and a landing. No one could believe it only had 22lbs in it. She moves pretty good. No need for more in my opinion.

    Hey Dave, I don't remember where it was in this thread, but I remember you siliconing the wire that connects to the steering bolts on the nose strut. I'm guessing they can rotate & hinder operation if not siliconed? Do you always do this, or only if a problem exist?
    Thanks, Jay

    I got 6 flights in yesterday in some lovely weather (including one flight where I got a bit carried away and managed to land with the main tanks empty and UAT half empty ). The plane is fantastic!

    Yes, with the gear down I silicon around the wire and steering posts. When the gear retracts the wires stay inline with the pin and like this I don't need bands or springs. They form a 'wave pattern'

    If you look at the bottom shots of my model, you can see perfect dear operation as no scuffs [8D]
