  • Low pitch range on 600LE

    My pitch range is only 11/11 which seems quite low?

    At mid stick everything is centred, I have extended the links from the swash a couple of turns as per Bob's vids to maximise pitch range but I can't even get 12 out of it. Is this normal?

    Flybar cage is centred at midstick
    Washout arms are centred at midstick
    I have zero degrees pitch on each blade at midstick
    Swash mix is at 60% on my spektrum DX7 and any more the the swashplate hits at bottom stick.

    I have full motion through the swash, it travels all the way up to the head and is just shy of touching it. It also travels all the way down to the collar and again, is just a mm or so away from touching. I was under the impression you could get 14/14 from this bird?

    I had one before but never checked my min/max pitch but it flew great. This is my 2nd 600LE and thought I would be extra thorough. Any help is appreciated.

    Perhaps someone could tell me the lenghts of each link they have on theirs so I can compare.

      I know it's a daft question but you've not got the washout base upside down or anything?

        Something a miss there if you have full swash movement there is no reason why you can't get more than 11 deg the length of the rods will have no effect on the overall movement

            Yeah, I get binding if I add any more pitch. I'll take some pics in a mo.

              This is something I've been looking at with my 600LE, you will find that it's possible to get 14 positive but not when you go negative. The problem seems to be down to the lack of any adjustment on the elevator arm, and a nice fat swashplate! So far I've only wound up the elevator ball link a couple mm along with the rear rods. Some people have used the Quick UK swashplate which is slimmer that the kits! (This would help both pitch range and binding) Something else that has been suggested is to use a longer bolt in the elevator arm to raise the ball link. This is what I'm going to try next, but I'm going to machine a small sleeve to go on the bottom of the ball link as it will no longer be seated in the elevator arm.

              I hope this helps

                Right, here are some pics. Not flown it yet so will see how it climbs. With any luck I won't even notice it.

                  it may not be the case but on my 600esp i could not get full pitch range, i had to cut the elev collar off and sit the ball link lower in the A arm, i had room at the top for greater range but could not get elev low enough. this mod meant swash dropped lower relative to A arm so allowing greater range. oh..if you do this you have to cut the allen key shorter too. might be unrelated...might not.

                    The problem with the LE kit is the fixed elevator A arm. You cannot adjust the swash position like you can on the standard 600. This has been covered on another forum but I can't remember where I saw it now.

                      that looks fine. i can only assume the headblock is longer or the swash is thicker if your hitting the top/bottom just about.

                      the A arm being longer i can see causing the swash to be high/low but it shouldn't effect the overall travel range. you can 100% get 14/14 out a normal 600N.

                        This is VERY strange....ive helped 2 club members set thier 600le's up and I have not seen this problem before.......carnt see it being the A-arm unless something isnt machined correctly.....

                        Yet I cannot see anything wrong in the pictures...

                          14 deg and you have to accept binding will occur in the corners. Plus when you check for binding remember the flybar will not tilt fully in flight. You will also have to accept the swash touching the bearing block area at full negative when the swash is tilted.

                            Does anyone know if the 600LE can achieve 14/14 stock? My old LE which I sold to Bladestriker was running 11 and as his latest vid showed it has plenty of pop with the OS55. Maybe this won't be an issue but just felt like 11 sounded a bit low.

                              Im thinking that they mean the swash is capable of giving +-14 as in the actual travel it can do when not connected before it hits the main block or the washout falls lower than the pins that align the washout base??

                              You may be able to get more than 12 but will bind if you have to much ail & elev??
