I got a DX5C and a 6200A Rx
For life of me I can’t get killer Bee to work properly, obviously it works fine with the Aux key on the Tx, no issues there, but when I turn off the DX5C it doesn’t kill the engine.
I’ve turned off the AVC, rebound, even held the Aux key in the off position during bind process as per the FAQ on Killer RC website, still no luck
Killer Bee is on the default dip switch settings
 
Maybe if you used the search function here you would find that your wasting your time. Avc and killswitches DO NOT mix.
As I said in my post, I’ve already disabled AVC as per Spektrum instructions, and can confirm the AVC is disabled
 
And as I've said in my previous post, Avc recievers and killswitches do not work at all. You can disable whatever you want but it still will not work
 
I am not at home where I can look right now but the main guy at killer RC emailed me a work around that worked for me. I will hunt it up later today and post it.
 
That would be great, thanks
Oh wow you responded to your own thread for once. And rep is right, doesn’t matter if you disable avc it’s still an avc reciever. And it would be dumb to do a “work around” on something like a Killswitch. Buy a sport receiver like this one I run https://www.horizonhobby.com/produc...6clG3RTj9vgIFHkt9JhUKcbImEcVVP5BoCIZ0QAvD_BwE
Use the search feature to set it up we have been over that many times here… there’s one in my l5b build thread I think

And this is the problem, if you can't produce the documents you promised to resolve his issue you shouldn't post as you have no useful information to provide. Reading that thread appears to be alot of beating around the bush and far more hassle than paying $60 bucks for the right reciever and being DONE and resolving the issue in a matter of a car ride and 10 minutes of install time, but you are right @foundryratjim your way makes so much sense im sorry I didn't think of it myself
 
Actually things have changed it seems. This is from P7 of the instruction manual for the 6200A receiver (y)

http://spektrumrc.com/ProdInfo/Files/SPMSR6200A-Manual-EN.pdf

DISABLING AVC TECHNOLOGY AVC
AVC may be disabled during binding.
1. Connect power to the receiver and quickly press and release the bind button three times (within 1.5 seconds).
2. Connect power to the receiver, power on, press and release the bind button three times (within 1.5 seconds from the first push).

When the AVC system has been disabled, the LED on the receiver will show three flashes upon power up, and then remain lit. The receiver is bound and operating normally when the LED remains illuminated.

TIP: If the AVC feature in the receiver is active and the AVC menu in the transmitter is Inhibited, AVC functions will default to the AUX 1 and AUX 2 operation, and in this scenario, AVC will not work correctly.

Selecting INH in the AVC menu on your transmitter will not disable AVC
 
Good information below, please take time to read

Thanks to all you guys for sharing your experience with Spektrum and Killswitch

I know different people had different opinions and experiences, but reading through all of them, there was no consistency and rock solid solution.

I personally had this issue but spent a lot of time and wasted a fair bit of money to once for all get to the bottom of this and I eventually did.

As we all know a killswitch connected to an AUX channel should kill engine via the remote which is the function a programmed key on your transmitter as well as signal loss which is a function of the receiver failsafe to take all channel to a predefined position.

For a killswitch to do its job properly, failsafe needs to be set in a way to turn off the AUX channel associated with the killswitch, so on radio loss the killswitch kills the engine. This is the point where most of people including myself having trouble. Realising that the issue is related to failsafe, forced me to properly understand the failsafe on Spektrum receivers. Not sure if you guys know but Spektrum has 3 different failsafe modes, 1. Hold Last, which simply retains all the channels as they are 2. SmartSafe, which lower throttle but keep all other channels as they are 3. Gas mode which lets you define what happens to each channel on signal loss.

Different failsafe mode have different setting features, the manual of your receiver explains how to set each mode

The following text is direct from Spektrum manual:



  • Standard Mode
If loss of signal occurs, SmartSafe™ technology moves the throttle channel to its designated failsafe position (low throttle) that was set during binding.

All other channels hold their last position. When the receiver detects signal from the transmitter, normal operation resumes.

  • Gas Mode
Preset failsafe is ideal for most nitro/gas vehicles. With preset failsafe, all channels go to their preset failsafe positions if the signal is lost, preventing an out of control situation.

When the receiver detects signal from the transmitter, normal operation resumes.


as per the Spektrum surface receiver comparison chart which I’ve left the link below, only 3 models of their current receivers have the capabilities of the GAS mode failsafe , those models are SR215, SR315 and SR515.

https://spektrumrc.com/Content/Media/PDF/64930-dot-1-surface-rx-chart.pdf

The Killswitch issue on Spektrum has nothing to do with AVC as most people think , however interestingly enough , the 3 models I mentioned above are not capable of AVC. Basically they don’t make a receiver with AVC and GAS Mode failsafe which I understand why, AVC is mainly designed for small electric RC that is not easy to control as a 1/5th GAS.

In addition, if you look at their comparison chart, the only 3 models with GAS failsafe have been recommended for 1/5th GAS cars , so I’m puzzled why Horizon is shipping out 5ive T2.0 with a SR6200A which as per their chart is intended for anything but not a GAS car …..!!!! they are selling gas cars with unsuitable receivers fitted in which is causing a lot of headache out there.

I changed my receiver to a SR515 and got the killerbee working in 5 minutes.

What I’ve posted above was also a news to KillerRC guys , they are going to publish this on their website to help people in future
 
@mj.jafari you do realize that I have mentioned the sr515 and also mentioned the time I spent with horizon figuring out the same issue and horizon owns spektrum, did you figure that out too? Jesus man
 
I did see all of that but there was no logical explanation as to why, I needed to understand the underlying issue, no one spoke about the GAS Mode failsafe which was the keyword
 
Well kudos to you for going in a giant circle for weeks where it served no point for me or anyone to go as far as you did because there was already an immediate solution to overcome the fact that avc and kill switch just don't work
