Hitec Spectra Module Potential Problem?
I've been flying a Spectra Module in a Futaba 9C for some months now with not a single problem. I recently flew a new airplane and everything was going well. My flying buddy asked me why the lights on the module were blinking (he could see the back of the radio). I went ahead and landed the plane and did some checking and it seems that the servos movement causes the red and blue light to blink on and off. These are a different brand of servos I had been trying out on a couple of 72mhz planes and they have worked real well for me. Is this some type of interference caused by a cheap servo or what? Anyone experienced the blue and red light on the module blinking on and off? On every other plane I have flown since I have seen that the red light stays solid red as it should. This is with Futaba and Hitec servos of different types.
Thanks, Tim

RE: Hitec Spectra Module Potential Problem?
Yeah, thanks. I changed out batteries and switches and no change. But I hooked up several spare Hitec servos and the lights stayed normal. So it must be a feedback problem with the EXI servos. I guess I will be looking for some good digital MG servos for this one.

You are getting the low voltage alarm indicating your RX battery is low. Could be low in general while flying or low when you manuver and the servos load down your batteries. If you had an Aurora 9 TX you would hear a beeping also and see the Rx voltage on your Tx display.

I don't think it is low voltage. The blue light is flashing also. When I plug Hitec servos in the receiver and cycle them it doesn't flash. I can't find anything in the Hitec manual that describes what I am seeing.

Well I have the module on a Hitec Eclipse 9 so it may not work the same on your TX. But red and blue flashing is range check power down on my system. You seem to have a very stange condtion if it only comes with different servos.

Yeah, exactly. I am afraid of those servos now, even though I have been using some on a plane flying 72mhz with no problems that were apparent.

RE: Hitec Spectra Module Potential Problem?
Spectra modules must be modified by adding acapacitor & retuning before being used with a Futaba TX.
Thiswill provide a better RF link.
This work must be done at a private repair shop as Hit or Fut will not do it.

Hi Guy,I have been using the Hitec 2.4 modular in both my Futaba 9C and 8u radios,The Aurora radio does show you the receiver battery power.In my Futaba radios,If you have a bad receiver battery the transmitter modular beeps 3 times,pauses than beeps again 3 times continuously,with both lights blinking,giving you plenty of time to land safely. thanks Ed

I have the plane that I was having the problem with flying fine now. It was one or maybe two bad servos causing the voltage to spike down. If I hadn't have been using the Spectra module, then I might have lost a plane not knowing I had an intermittant problem. Thanks Hitec.

Hi Boberos, What are you talking about???? It works fine out of the box,for me and about 8 others also using the 2.4 hitec modular, in Futaba radios in our club. Thanks Ed
