Dave Bran Posted January 6, 2013 Share Posted January 6, 2013 Well, my X4 arrived on Friday and to say I was disappointed with it was an understatement. Despite being well used to Quads I found it difficult to control even for simple flying around at slow speed, and impossible to pirouette without it drifting out randomly but mostly backwards on stopping, needing full forward stick and an agonising wait to get forward motion back (if you had the space). It would fly, but really poor control compared to the Twister Quad, even when rates wound up (setting rates/sensitivity is in manual). At this time I only had the one battery, so testing was very drawn out. I took it to an Indoor Fri night with much more space but it was no better there. A crash kit which includes a battery arrived Sat a.m. so I took it to an Indoor last night (Sat). No better........ Someone there asked what I thought and when I said it would not even pirouette properly he instantly said there was an undocumented calibration mode, and said what to do. We tried this and it did not work!! He then rang someone who works for Ripmax who confirmed what we were trying was the right thing to do, but several more tries, no good. Then a youngster turned up with one, asking as it was trying to drift the wrong way for stick moves. He'd not altered any settings from supply. His also would not end piros correctly. The Calibration process worked first time on his and it then worked well. Tried mine again and no luck. What we were being told to do (on Mode 2) was:- Power up and allow to bind Press down on left stick to operate switch under it and hold it on Wriggle right stick left/right "Eye" lights will flash and calibration done!! Getting back home (late) I went hunting and found in US forums that others were calibrating it differently, viz:- Power up and allow to bind. Press and release right under stick switch to put it into "Expert" mode (says Expert in tiny letters on LCD and red LED flashes) Hold full right rudder on left stick (care - no throttle as it is live) While doing this wriggle right stick left/right "Eye" lights will flash and calibration done!! This worked on mine and it now flies MUCH better, piros being flat and ending in stable hover. One wonders how many are getting returned to the poor shops, or just thrown in a cupboard as too difficult................. Hope this helps some people.......................

Dave Bran Posted January 6, 2013 Author Share Posted January 6, 2013 I'll not alter my post above, but my subsequent searching seems to indicate that the distributors are CML and not Ripmax as the person said to me last night, he certainly gave the impression it was a Ripmax handled product but maybe the Ripmax person had some dealings with that model at some point so knew............anyway, it's CML that list it on their website, and though I have looked and searched, cannot find any info there on calibration. ALSO, further searching suggest that setting the accelerometers under calibration should take place with the trims zero'd. If that produces a quad that drifts in any direction, prop it up with paper, etc in a counter direction while calibrating and you'll end up with a Quad that is perfetly trimmed with trim controls at zero. Tried and yes that works, too!! Quote Link to comment Share on other sites More sharing options...
Old Geezer Posted January 6, 2013 Share Posted January 6, 2013 So - I 'm getting a Q'copter - do you reckon I go for the Twister, rather than the Hubsan? The Twister's a bit more money, but if I buy the cheaper alternative and hate it - - - - ! Quote Link to comment Share on other sites More sharing options...
WolstonFlyer Posted January 6, 2013 Share Posted January 6, 2013 Thanks for this info DaveI have just done this calibration on my 2 day old X4 and the second method worked. It now flies so much better Hubsan / CML really should include this in the instructions in the box, even if it was just an extra loose bit of paper.

The Twister's a bit more money, but if I buy the cheaper alternative and hate it - - - - ! From my experience with owning both, and taking into account the sheer number of very happy Twister Quad pilots I know, you'd need very good reason to discount the Twister one! Conversely, I don't think you'll hate the X4, especially if you calibrate it properly and have a very small flying space, my dining room isn't large, and with computer gear everywhere, space is a premium, yet the X4 will now fly circuits and eights with ease, wheras while the Twister also will, its a bit tight for it. I'm told the smaller X4 will actually stand a greater breeze, can't comment yet!! Quote Link to comment Share on other sites More sharing options...
Andy Loges Posted January 6, 2013 Share Posted January 6, 2013 Thanks for this info Dave, Just tried it, the bottom method in bold worked for me. Transformed it's flying. Now flying lovely circuits in the model room, and it is not a massive space, pirouettes superbly. Quote Link to comment Share on other sites More sharing options...

Paul Marsh Posted January 8, 2013 Share Posted January 8, 2013 Mine's uncontrollable, after the calibration. Put the new motor in, but totally crazy. Soon as I fly it, it flips over and crashes. Mine has never really flown very well and not very impressed... Quote Link to comment Share on other sites More sharing options...
WolstonFlyer Posted January 8, 2013 Share Posted January 8, 2013 Have you zero'd the trims and then calibrated?Mine went a bit crazy when I calibrated with forwards trim applied.Probably a daft question but have you got the white props on the front motors? Quote Link to comment Share on other sites More sharing options...
Paul Marsh Posted January 8, 2013 Share Posted January 8, 2013 Yes done all that. The white props are on the front. Only replaced one prop, which was broken. All going the right way, but can't seem for it to keep level. Quote Link to comment Share on other sites More sharing options...
WolstonFlyer Posted January 8, 2013 Share Posted January 8, 2013 And you have the correct A or B prop?Thinking out loud here but does the new motor seem to be spinning the same speed as the other three, it is probably hard to tell but could it need running in?

Paul Marsh Posted January 8, 2013 Share Posted January 8, 2013 Re-centered all the controls and re calibrated. Now actually flys!!! Just a bit out of calibration/ Quote Link to comment Share on other sites More sharing options...

Mr.B. Posted January 10, 2013 Share Posted January 10, 2013 Dave you hero. My son I much happier with his X4 now. Method 2 worked for us. Quote Link to comment Share on other sites More sharing options...
Dave Bran Posted January 10, 2013 Author Share Posted January 10, 2013 Good to hear! Tues evening at an Indoor I gave several people a go, they all thought it was superb. One experienced guy lost orientation and slapped it into a wall about 20 foot up, it crashing to the hard gym floor rotor side down........no damage at all!! I took it in to the after school club I run today, gave it to two relative beginner 12 year olds and a 6th former who helps me...........they all flew it well! Just shows that if it is set up properly it's ace and most can fly it no trouble. I should be on a cut here....................... !!!!!

Mr.B. Posted January 11, 2013 Share Posted January 11, 2013 Tomorrow night will be our first indoor session of the year. I've got a new toy (PZ pole cat) to try out as well. It makes you wonder why Hubsan don't put calibration in the manual. Quote Link to comment Share on other sites More sharing options...
Lee James Posted May 7, 2013 Share Posted May 7, 2013 Sorry if this is wrong to ask here, but i just got a x4 and done everything as manual said, but my controller only ever shows a battery indicator and the x4 just flases blue, if i press and hold a button on the controller it then will flash red but still wont control the x4 any ideas anyone?

Tony Read 2 Posted May 8, 2013 Share Posted May 8, 2013 Hi Lee, there are no wrong questions, only wrong answers! Try moving the throttle stick fully up then fully down to arm the quad. Quote Link to comment Share on other sites More sharing options...
Lee James Posted May 8, 2013 Share Posted May 8, 2013 Hi i just tried that .. nothing =[ il try explain a little bit better when i switch my controller on all that happens is it shows i got full battery, no hubsan logo or anything else on the screen? the lights on the x4 flash blue which means its not binding, controller does nothing unless i press and hold a button down ... in which case i get a red flashing light ... and then it will just keep doing that Quote Link to comment Share on other sites More sharing options...
WolstonFlyer Posted May 8, 2013 Share Posted May 8, 2013 I think mine has done this a few times. Try connecting the battery to the x4, put it down on a flat surface, wait a few seconds then swith the transmitter on with the throttle fully down.

WolstonFlyer Posted May 8, 2013 Share Posted May 8, 2013 I just saw your earlier post saying the lights on the x4 are just flashing blue. This usually means that the battery is low on power.Have you charged it up fully? Quote Link to comment Share on other sites More sharing options...
Lee James Posted May 8, 2013 Share Posted May 8, 2013 i put it on charge with the charger supplied until the light come on was about 30 mins? i shall try again now Quote Link to comment Share on other sites More sharing options...
Lee James Posted May 8, 2013 Share Posted May 8, 2013 Sorry i meant the light come off ( got a lil heli that is charged when light on haha ) Quote Link to comment Share on other sites More sharing options...
