DeviationTX 4 Devo7e + JXD 388 cut off

Hi !,

I've loaded the V202 modelfor my JXD 388 and the quad doesn't works as it should do...I bind the model and everything it's ok but when I push the throtle stick the motors start to spinning after 1 second, then they stop and start again....

Any clue?.

Thanks in advance.

Double check your antenna soldering on your nRF24L01+ and/or all your soldering connexion.

Hi SeByDocKy !

I'm Israel (the guy woh ask you about the INI file )

Thanks for your help, I'll check the soldering of the antenna and the connexisions.

BTW this is the moulde I'm using...There is ny other better?

Hi, I need to check the soldering points ( I forgot my screwdriver at work....) but I've tried the V944 which uses the same module ( but different protocol) and it flies perfectly, no glitches.... Could be a problem of protocol?

No ... The V2x2 is very solid. With the original TX, the connexion is solid ?

Hi,

Yep, with the original TX conexxion is solid as a rock, no problems so far, I can do flips and fly smoothly . WIth the Devo 7e and the V944 (4chn. FP heli) I can take off and fly even better than with my Turnigy 9x + ht-8 module, no delay... so I think the module it's working at is should be... now only rest to check the soldering point but I rembember to check it twice before putting all togheter into the radio...

I'm thinking about something wrong with the 388 PCB board...maybe a new version of board....

I can control mine > 100m. I am very surprized. Did you select 150mW as output power ?. Try to bend vertically the JXD 388 antenna. Do you have other V2x2 quads ?

Yes, I've selected 150mW as output power...but still working bad...if i press the light switch (trim) it takes 1 second to turn 'em on or off.... Ive flashed a nightly build but when i turn the devo on i get a bad protocol....? Any special procedure for flashing it? Need it a previous wipe?.


Thanks in advance.

Thanks in advance.

With the last nightly build; did you modify your hardware.ini ?

Hi SebyDocky

Yes i've downloaded the last nightly build, after downloading it I've used the Dfuse to update the radio...I'm not sure about upgrading the radio with the nightly buids....Need I to put my old ini file? Anything else?.

Thanks in advance.

Since few release you have also to modify your hardware.ini according to your installed chips

Hi !,

I've checked twice the connexion and everything it's OK, I've tried to fly the JXD 388 with the antenna out (to improve range) and doesn't works...I'll try to put the last nightly, if it doesn't works I'll give it up...anyway I've a Hubsan X4 on the way.....

Thanks
