Title: need help,Hitec spectra not working properly.
Post by: kaivalya on February 22, 2015, 09:22:50 PM
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.

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

I thought  it must be in PPM mode to work.
