    CX2 lacks forward speed

    Hi, I flew my CX2 outdoors the other day (flat calm!) and I couldnt get it to fly forwards more than 3-4mph with full forward cyclic unless I gave it a lot of throttle when it was then also climbing at around 40 degrees.

    Is this normal? I've checked the linkages and the servo is definately pushing the swash plate as far as it will go.

    pop the ball link off the swash and lengthen the rod by 1 turn

          move both your servo links out to the second hole in the horns from the servo, take the wieghts out of your flybar Davey, if you want to make 'em really interesting, a couple of Extreme 180 motors and a heatsink (will pull a suspended sausage faster than a manic jack russel )

            The slightest breath of wind will stop it flying forward.

            Same on the Medivac I had.

              Thanks for the suggestions. I'll give them a try. I've just bought a blade 400 so hoping that will be a bit more responsive!!

                I can heartily verify the Jack Russell calibration, as I have a test unit of my own.

                  I've moved the control rods out to the second hole and that has more than doubled the forward speed, thanks. I might try the flybar weights next!

                    eyup Roger, howz that trumpet of yours doing ? ,,,just been to a Buell bash last w/e with the Mini Titan,,,,,cleared the field in 5 seconds flat

                    heres one of my "test units"



                    glad it worked for you Davey, keep an eye on your swash when you're using this set up, it will separate, I wound up making a hybrid alloy/oe plastic one that dosn't come apart now

                      Nah then Swampster! The old Trumpet is doing nicely thanks. Due for it's MOT (always good for a laugh on the rolling-road brake tester. "What the f***! Were they all like this mate?" "Er - yes actually. Usually worse.") - then we're ready for a bit of Wallace and Gromit style bimbling around the Dales in 'me goggles and pudding top when the weather is more pro ancient British electrics - ie.very dry.

                      Where was the Buell bash? .... oh, and how many test units have you got? My sausage snaffler runs 100 mph berserk circles when I mess with a heli in the garden - great fun.

                        down welsh wales, at one of the guys places, know what you mean about the trumpet brakes, used to run a '70 T120r for a number of years complete with comical hubs had to go when I ran out of magnets to trail behind me to catch the bits that fell off.

                        I've a matched pair of furry slippers meself, Gizmo, (the little guy in the photo, aka "The clockwise barkin' squirrel" ) and Roxy, aka "Tatty 'olbit"

                        btw, regarding your ancient electrics, there is a spell you can chant before setting off that works quite well,

                        ,,,to the great god Joe Lucas, prince of darkness, to be chanted under the light of a zippo miles from anywhere,

                        "Oh bulb that be in headlight,
                        Halogen be thy name,
                        Give us this night, thy needed light, to guide us home from the pub,
                        ,,,and lead us not into dark ditch's,
                        ,,and deliver us from evil policemen,
                        For 6 is the voltage,
                        6 is the ampage,
                        ,,,and 6-1 are my chances,,,"

                          Jack's middle names is Slippas! Said in an NE accent 'cos of 'me Missus's Geordie connections and it's what I threaten to turn the little sod into when he's tried chewing the leg off another golfer on his big daily constitutional. God - does he HATE those trollies and daft trousers!

                          Joe Lucas - Prince of Darkness! I nearly wet myself. The electrics prayer is wonderful.
