G+_Michael Rawson Posted February 25, 2015 Share Posted February 25, 2015 Hi again - my second newbie quadcopter question! My kit is almost complete now, everything is hooked together and basically working apart from one thing. The roll and pitch controls seem to be locked together when I test the transmitter signal using Cleanflight (config tool). I've been in touch with the shop I bought it from - they seem convinced it's a transmitter setting that I've got set wrong. I've searched and searched but I really can't figure out what would cause this. My soldering is admittedly ropey so I wondered if I had shorted the controller. The shop owner has been extremely helpful but I think email is failing us now. I did send him photos and he thinks the soldering is functional, just not tidy (I agree)! All the motors do power up by number correctly in Cleanflight. Thrust and yaw operate motors correctly from the transmitter. The transmitter has a "display" menu which shows the channel numbers are (theoretically) working correctly, so somehow the signal is not getting to the quad correctly or something is interfering. I wonder if I've got a duff receiver? I'm using the Acro Naze flight controller and FlySky FS-i6 transmitter and receiver (see attached link). More specifics if it helps - if I connect channel 1 on the receiver and not channel 2, roll and pitch move exactly in sync with the stick going left/right. Likewise if I move that plug to channel 2 and go up/down. When I connect both channels in the correct order it becomes a little more erratic - like the channels are conflicting. R&P are still locked together but, for example, if I move the stick to the left, R&P stay in the middle - odd. If I've broken something then it's my own fault and that's fine (I just need to know which bit to replace!). But does anyone here have any suggestions? Again all help is very much appreciated. http://www.radioc.co.uk/Flysky-FS-i6-2-4Ghz-6CH-Transmitter-Receiver-p/3510.htm Link to comment Share on other sites More sharing options...
G+_Mikael Eidsvaag Posted February 25, 2015 Share Posted February 25, 2015 Sow me your soldering skills =) I do not any thing about that flight controller. But I am assuming you did not set you radio in some sort of mix Mode. like Delta wing config Link to comment Share on other sites More sharing options...
G+_Michael Rawson Posted February 25, 2015 Author Share Posted February 25, 2015 My dirty secret -https://plus.google.com/u/0/photos/105748782318106497750/albums/6119878871074381969 There is a "mix"menu in the transmitter but all of them are turned off. I've tried every available type of aircraft. "Helicopter fixed pitch" would be perfect if I could solve this. Thanks! Link to comment Share on other sites More sharing options...
G+_Mikael Eidsvaag Posted February 25, 2015 Share Posted February 25, 2015 Michael Rawson That locked better that I thought. I don’t know. Try to look at you radio for some weird setting. Or try some of the other port just to see if the controls have the same issue there. Try to swap singals with T&Y. It may also be that you did not get enough solder from the bottom side to the top. but most of the PCB card have connections between the thru hole pads. If you look closely at the header and you see PCB fiberglass layer, like in the mooting holes you do not have connections between the layers. But bee 100% sure before you attempt to solder the top side. You may end up with a rued board it you use your soldering iron to long at the same place Link to comment Share on other sites More sharing options...
G+_Michael Rawson Posted February 25, 2015 Author Share Posted February 25, 2015 TBH that is very possible. Prior to starting this build I had never soldered a circuit board. I now know that I missed out on some very basic soldering practices that would have made the job easier and hence better. However I would not be surprised if I've applied too much heat in the wrong place. Assuming there was nothing wrong with the parts that I bought (which seems reasonable) I honestly think it's the most likely culprit. Thanks for your help!

G+_Craig De Groot Posted February 27, 2015 Share Posted February 27, 2015 That sounds like your transmitter may be in helicopter mode. Helicopters sync up two channels (like throttle and pitch) by default. You should try putting your transmitter in airplane mode and see if that works for you.

G+_Michael Rawson Posted February 27, 2015 Author Share Posted February 27, 2015 Hi Craig - yes it was in heli mode but I've tried every setting and it still does the same. Just to confirm I went back and changed it to the plane/glider option but there's no change. I'm going to see what happens when I put a new flight controller in. Fingers crossed!

G+_Michael Rawson Posted March 4, 2015 Author Share Posted March 4, 2015 Well I swapped out the Naze for a board which came pre-soldered. My fears have been confirmed but at least I'm on the right track now! Link to comment Share on other sites More sharing options...
