Hello,
I have a Hitec Optic 6 tx (35Mhz).I rcently purchased spectra 2.4ghz module and optima 7 ch. receiver.2.4 ghz module fitted in place of 35mhz and bind.But now when i start tx and rx, all servo and main motor starts automatically and moving automatically when i touch the stick.When i touch any of the stick all servo moving unevenly.Is the module  not working properly(faulty) or not bind properly?any one to guide me about problem and any solution?

Thanks in advance.

did you check the ppm mode, what is select negative shift or positive shift ?

if needed you can update your module/receiver to the latest firmware.

Sahilji,

My tx was on qpcm mode,after your guidence i change to pcm mode and now tx and rx work perfectly,thanks for the advise.Now i am checking for spectra module update with hpp-22.
Thanks once again,

I thought  it must be in PPM mode to work.

it is PPM mode, must have been writing error. (see page 8 )
