  • Ballistic headspeed and pitch

    Hi all,
    What headspeeds and pitch settings are advised for 710mm blades on a ballistic?

    At the moment I have 2000rpm at +/- 14 degrees as per the standard vbar setup but im reading that some people think this is to much?

    The ballistic hasn't flown yet but the ENV flew nicely on those settings

    Scorpion 4035-560 motor, 12t pinion, 6s 4000mah packs, 120amp esc if it matters.

    I'm not sure about the ballistic but I've got my Rave's set up with 1950 - 2000 headspeed and around 11 degrees of pitch and that seems more than enough for me.

      Depends how you like it, beauty with the Ballistic is it will fly within a large spread of RPM. 2000 isn't insanely high on a 90, usually 1850 is nimble, 2100 up pretty lively. Key is do what you want with the lowest headspeed to achieve it/match your style then you will be rewarded with more flight time.

      As for pitch again personal. I run +- 14 linear in all modes. 14 only gets used really for Auto's I just manage my stick and makes it more sensitive, generally in flight +-10 will get the job done.

        I'm using the following in both my ENV and Ballistic

        Headspeeds
        Normal flight = 1600
        Idle-up 1 = 1800
        Idle-up 2 = 1960

        Max pitch is at +12 and -12 degrees

        Above works really well for me

          Cheers guys, sounds like im not a million miles away with my proposed current setup so will probably leave it as is, might knock the pitch down to twelve and see what it flys like at some point

            Personally, i think 14 degrees of pitch is too much. IMO 12 degrees is fine. But each to their own. Im running 2060 in idle 1 and 2150 in idle 2 on my Ballistic. Im using a 13th pinion and an Ultimate motor. Im using the Rail 696 also. Its a monster...

              Depends how you use it, or not as the case may be ;-) Joking aside as said in flight your prob not using much pitch at all but to hang out Auto's 14 is very useful.

                Ballistic headspeed and pitch

                I'm running 15 on my g4 but only at 1500 rpm. Pitch adds the bite that the rpm lacks.

                As above it's all about personal feel.

                  Lol, most folk i have seen running 14 degrees bog the hell out of it at every turn. Using a lot of pitch is not big.... and its certainly not clever . 12 gives you all you need. Collective management does the rest

                    +1 Collective management is key, not all pilots are equal rest is setup tailored to your flying style preferences.

                    "Using a lot of pitch is not big and its certainly not clever" pretty bold statement. I think that shows lack of understanding of setup/useage and other flight styles maybe different to your own.

                      I won't mention any names but I know of several top pilots that use 14 degrees of pitch and use it well with no bogging.

                      Its all about pitch management and if you can't use it then settle on less.

                      Regarding your motor isnt 560kv too high for a 90 size heli.??

                        I've used 14 for the past few years, collective management means I didn't bog the hell out it at every turn!?! It allows you to have a decent amount of pop, and viciously fast pitch response, but only if you are capable of using it without destroying headspeed.

                          It's just that little blip that makes it pop nicely and change direction that little bit more positively.

                          Don't really have bogging issues now I'm getting better with the collective management.

                            Lol... that was a joke my friend. Hence the smiley face you have seen fit to not add when quoting Your right i don't have an understanding of set ups to a great degree as i have someone do my builds and set ups for me. Its not a side of the hobby i do well at. But you seem to be suggesting my skills maybe limited because i "can't" use 14 degrees of pitch as you say. It is not that i can't, more that i choose not too as i find with 12 degrees plus added pitch boost on the vbar very suitable for my flying style. I fly pretty hard too.

                            I just see a lot of people struggling to fly with any finesse then discover they are using 14 degrees with an underpowered set up. But peoples definitions of what constitutes as controlled flying is different too.

                              Thanks for clearing that up. Prob with written word it can be misinterpreted in the context it was made and in this case was then by me. On face if it just thought you were been rude. Now putting that slide as you clearly weren't the smiley face was lost. The thing to note is a setup with 14 or whatever degrees you decide on doesn't necessarily mean you use it constantly in flight. A larger range with linear curve gives more sensitivity and = less collective travel to achieve the same moves. Nominal pitch required stays the same. You could of course use expo to achieve the same result or pitch pump facility. If your power can take it some moves and utilising your chosen range can be very rewarding.
