I was wondering if someone could help me sum up all the problems experienced by some spektrum users. So far, this is what I know about:
1. response lag on tx inputs (only on carpet???)
2. temporarily going into falsafe mode after small crash
3. trims changing
4. bad bind button
Was there anything else? Is anyone actually experiencing glitching? People who find that they must use a power cap...are you sending your units in, anyway? I just received my 3pk unit yesterday.

Is it ok to cut the antenna per the instruction down to like 3.6 inches or so? Has anyone done this? I just received my unit for my ko radio today! Also, I'd assume that since this is from teh new patch that it comes with the latest software?

Very happy with it so far.

You could check the hobbyshop that I frequent. I'm pretty sure they would have one. http://www.theworldofhobbies.com

Call Horizan and ask for John Adams. He next day aired mine after I explained that they had had it for over 2 months!

AHA that is the filters I was looking for. No one had them and I wanted to buy some. I guess I will be ordering them. Anything to stop glitching from happening I'm into. I use the Bigger JR ones on my speedo leads and my servo leads. People are like do you need those for since you have a Spektrum but I was like I had glitching before and this is just a precaution. Not like they weigh really anything.

I'm an engineer, and used to design power systems. I'm waiting for my spektrum unit to arrive. The addition of the capacitor to fix what sounds like oscillations in power seems like a classic stability problem for the power circuit in the receiver. The FET's banging on and off in the digital servo's can make a a very spikey load current profile. I believe the receiver has it's own boost circuit to allow a wide input voltage to run the receiver. If the boost supply is incorrectly compensated or has too little output filtering, then the supply voltage will oscillate.
A crash would cause a similar instance in that extremely high current spikes at the servo or motor could also cause stability issues. This could be as simple as changing a small chip capacitor value in the receiver. I once had a similar problem on a production run where the vendor that did the manufacturing installed the wrong compensation cap and the fan noise (similar load profile to a servo) caused the supply voltage to oscillate and shutdown the power supply. Hopefully spektrum is thinking.
