  • flybar less dampers

    i'm going to try flybar less on a spare sceadu i have (the mans way with no electronics)
    the question i have for the ones that are running fbl do i use std dampers or hard dampers?
    i'm using the std hirobo head with the flybar removed
    does the align fbl head have dampers in it or is it a ridged head?

    Generally you'd want harder dampers, but I'm not 100% sure that'd be the case with no electronics.
    Can't see the point of doing it myself?? Sure it's do-able, but it's never likely to fly better than it did before!
    If it was on a scale model, with a multi-blade head then maybe it'd worth trying... Then again.. No it wouldn't! Good luck though!

      if you use an electronic flybarless controller, such as V-Bar, the dampers should be hard (according to Mikado's instructions). They state that softer dampers act like play in the mechanics and make the controller's job more difficult.

      Unstabilized, things may look different, don't know.

        I get the feeling it might be more a bag of spares by the end of it. Why do you want to do it? As said above it's not going to fly better than with the flybar, you must know that, you do know that you've been around long enough. Confused.

          I asked this very question this week in Fastlads.

          The answer is "Yes" they are the very same dampers used in the flybarred head.

          Your reasons to go FBL without the electrics are your own but I imagine it will be a pig to fly.

          Good luck anyway.

            thanks for the input guy's
            i'm looking at going scale with it
            and yes i know it won't fly aswell as a flybared model
            and the bit factor is the cost no electronics =£0 cost as i have a swash driver that fits the mainshaft
            electronis + £high
            if it doesn't work out then i put the flybar back on at no cost

            and i do fly a 3 blade head wth no electronics so it won't be a huge shock to the system when it gets maidened

              If you change your mind I'll have a Skookum 360 for sale (as soon as I can get hold of a Total G) at a reasonable price.

                As a matter of interest how does your 3 blade head fly in comparison to a flybared one?

                Also once you have flown your fbl Sceadu would be interested in your findings in comparison to both.

                  the 3 blade head is a lot more sensitive to your control inputs and pitch's up it the wind compared to a 2 blade flybared head
                  i use expo and reduce the control throws to stop myself over controling the head
                  and with stick time you get used to how it flies

                  i'll keep you up to date on how it goes but it may not be for a coulpe of weeks before it gets flown as i need to look at the power suply in my turbulence as the rx battery dumped its charge in flight yesterday
                  the first i knew of it was the fail safe shutting the engine down, not ideal in a slow lowish circuit but it auto'd down without any problems

                    Interesting little project Dave.

                    I would have said harder dampers than usual.

                      My 2p worth is that on a "normal" model the collective is set in the region of +/- 11 and the cyclics around +/-8. Without stabilisation your fingers cannot move in small enough increments to stop over correcting.

                      I would suspect that as a first test reduce the cyclic to maybe +/- 3 or 4. A full size after all doesn't have anywhere near the range of models.

                        after having problems with the control rods flexing and the blades going miles out of track
                        i've now fitted the align g3 rods with quick uk ends (the align ones are too big for the balls) and this has cured the rod flex problem (thanks moonmanflyer for the info on the rods)
                        its had around 1/2 gallon of fuel trough it today in winds gusting up to 15/20 mph and its flying very well
                        i started out with 30% expo but its down to 0 now after test flying
                        i've only yet flown circuits with it but i aim to get it inverted the next time its out (i know i said its for a scale project but you just have to do these things)

                        as expected it was pitching up a little in the gusts in forward flight but no way near as much as i thought it would
