after a few takeoff ground runs in high cross winds causing my Inverza to run off the side of the paved runway and into the grass and flip over, I can't get it to bind to my dx6i and also the ESC gets hot while trying to bind. I am trying to decide whether to spend $28 to buy a new ESC or if if its a new receiver I would need to buy for $80. Within 10 seconds or so after connecting the battery to the ESC(while shorting out the bind plugs) the ESC gets very hot, not just warm but hot. I hear the 3 tones immediately upon connecting the battery. Sometimes I see the light on the receiver blink then go out and sometimes I don't see the receiver light illuminate at all. In either case, binding does not occur anymore and the ESC gets very hot. Is this problem most likely solved by replacing the ESC or the receiver or both? Thank you..... Pilot guy

Hello Pilotguy,
The Rx is not the cause for the ESC to be heating up. Most likely the loss of bind and no ability to rebind is being driven by inadequate Rx voltage provided by the ESC.
I would break this down into 2 steps to confirm if there is one or two or even possibly three problem devices if it was my issue to resolve.
1 - Power up the Rx with a separate Rx flight battery and rebind. If no blinking lights upon powering up with bind plug in then most likely the Rx got fried by the ESC.
2 - Power up the ESC without the Rx connected and the motor leads disconnected. If unit heats up then you now know it is the culprit.
If it doesn't heat up, then reconnect the motor leads(no prop please) and if it heats up now then you likely have a motor with a shorted winding.
This would be an extremely low percentage failure mechanism however but it is still possible.
Good luck and best regards,Warbird Charlie

Hello..as per my experience actually the Rx is not the cause for the ESC to be heating up. Most likely the loss of bind and no ability to rebind is being driven by inadequate Rx voltage provided by the ESC. You should try Power up the Rx with a separate Rx flight battery and rebind. If no blinking lights upon powering up with bind plug in then most likely the Rx got fried by the ESC. Also do Power up the ESC without the Rx connected and the motor leads disconnected. If unit heats up then you now know it is the culprit.

You guys sure know what you're talking about. Thank you. It is not quite solved yet but here is an update on where I am.
I removed the black connector that comes off the ESC and which connects to the receiver to power the servos (is that the BEC?). I then connected the battery to the ESC to try to bind (pair of tweezers squeezed against the 2 bind pins, of course). Immediately I heard the 3 tones (sounds like the tones come from the motor itself). I saw no light of any kind on the receiver(not blinking, not steady, no light at all). Within a few seconds I noticed a chemical smell coming from the receiver. No heat from the ESC this time, even after leaving the battery connected for 2 minutes. I went through the bind procedure but no binding occurred.
Based on your comments, am I correct in assessing that the receiver is defective and needs to be replaced?
Thanks for for sticking with me on this...Comment

Hello Pilotguy,Originally posted by Pilotguy View Post
Well at least I know what I'm talking about and appreciate the vote of confidence, the other guy(CoryGrady) simply copy/pasted my comments verbatim and then sprinkled these words in "Hello..as per my experience actually" and "You should try" and "also do". No kudos to you CoryGrady for your first post being a lame plagiarism!
Back to your problem Pilotguy, the connector that comes off the ESC and attaches to your receiver is as you guessed correctly the "system voltage" that is provided by the BEC. Your second sentence totally lost me because you just indicated in the first sentence that you disconnected the Rx from the ESC but then you say that you are trying to "bind" with tweezers?????? No binding plug avail?. The ESC tones that you hear are being generated by the motor which is normal. So how did you get power to the Rx? Your explanation has me baffled and I can't give any advise based on that process you described.
Best regards,Warbird Charlie

There is something wrong with the way something is plugged in... or the ESC... or the RX... or a servo (or more than one servo)
REMOVE THE PROP (if installed)
Unplug EVERYTHING from the RX.
CAREFULLY plug the ESC into the throttle channel ensuring correct polarity.
Now try to bind (ensuring the bind plug if applicable is correctly installed)
Do not use tweezers... If you do not have a bind plug you need to get one or make one. Its too easy to cause a short with the tweezers.
This will limit the issues to ESC or RX.
Successful binding should give an additional ESC/motor tone then throttle should be responding to stick position (note that throttle reverse could have it go to programming mode)
ESC tones being correct is indicating that the ESC is probably fine. The BEC section getting hot means there is an excess current demand.
Many modern ESCs will shut down on excess temp before they burn up from the BEC being overloaded. Some just shut down the motor section in the hope the lack of power will slow the plane and unload the BEC through reduced aerodynamic load on the control surfaces. Some will shut down both the BEC side and the motor side.
Hopefully you have not done something that shorted the RX and burned it up.... but its very possible.FF gliders and rubber power since 1966, CL 1970-1990, RC since 1975.

OV10- you are correct to be confused by what I said, I re-read my post and realized that it is not possible to bind if the BEC connector(coming off the ESC) is disconnected. What I meant was, by disconnecting the BEC connector from the receiver, I was trying to see if the ESC would heat up or not, which it did not. I still heard the 3 tones from the motor. Does this tell me that the ESC is probably not the problem here?
All - Also, after re-connecting the BEC to the receiver, I then tried to bind. while trying to bind, the motor emits a single tone in 2 second intervals (I believe this is normal bc it did that when binding occurred normally and before I started having problems). But the receiver emitted a chemically smell(which eventually goes away after disconnecting the battery). The E-flute Inverza does not come with a bind plug. I have been using tweezers.
Let me know if you need more info.
thank you...Comment

Hello Pilotguy, after reading your last post I gotta stand with fhhuber on the premise that the Rx got toasted.Originally posted by fhhuber View PostWarbird Charlie

Well, Here's what happened today... I managed to disconnect all connectors from the receiver(Rx)(which was really hard bc it is a small Rx with small connectors and difficult to work with. I then connected the ESC connector(BEC) connector to the throttle channel on the Rx. I then hooked up my tweezers to the bind pins and connected the battery to the ESC. Everything else remained disconnected. I then heard the 3 tones come from the motor and saw the Rx light blinking. That's right the Rx light was blinking. I then put my Tx in bind mode and it actually bound. After 5 seconds or so the Rx light turned solid and I heard what sounded like when servos neutralize(although only the ESC was connected to the Rx). The same servo sounds I hear during binding.
I then disconnected the tweezers, battery and Tx turned off. Feeling lucky, I then connected the elevator, rudder and aileron servos to the Rx. Figuring that the Tx and Rx are now bound, I turned on the Tx then connected the battery. Moved the Tx sticks but there was no movement from any servo/control surface. The ESC got quite hot. I then disconnected the battery from the ESC and was left wondering what to do next. So I came here to post this.
Please advise further. I am at a loss now.

Did the motor run when it was bound with no other servos plugged in when you advanced the throttle? (make sure propellor is off the motor) If yes then try plugging one servo in at a time. If that one works then remove it and plug in the next one etc etc..... If all work singly then I would suspect the ESC is failing under load but I'm betting you find one that is bad.LaurenComment

You all are awesome for sticking with me on this, I can't thank you all enough!
The culprit is somewhere in the rudder channel. I performed the steps Flygirl mentioned about trying one channel at a time. First I was able to bind with only the ESC connected to the Rx and with nothing else connected. Yes, the Rx light blinked then it bound then Rx light stayed on continuously. I throttled gently and the motor spun. I input different throttle positions and the motor work ok.
I then added the rudder connector to the Rx so now the ESC and rudder are connected. I moved the Rudder stick on the Tx but there was no response. No sounds, no nothing. I advanced throttle and the motor worked ok. I then dis-connected the rudder and connected the elevator along with ESC and it worked ok. I dis-connected the elevator and connected the ailerons along with ESC and it worked ok. I then connected all 3 control surfaces along with ESC and all worked ok except for the rudder. No response at all from rudder, no sounds, no nothing.
so if the rudder channel is faulty, where is the fault? In the servo or in the Rx itself?Comment

Amendment to my last post(9:44 AM)... fhhuber had the first post about connecting each channel independently. That post came in yesterday (Thursday) at 1:42 AM. I only mention this since I specifically mention Flygirl in my last post so this is just to make sure I give credit where it's due. I don't mean to single anyone out specifically bc I greatly appreciate all of your posts ( except that one plagiarized post from CoryGrady).Comment

Try a known working servo in the rudder channel... if that works, then its the rudder servo, if not then its the RXFF gliders and rubber power since 1966, CL 1970-1990, RC since 1975.

Update: Since I had decided that the culprit is in the rudder channel, I decided to look at the rudder servo closer. Actually, I used my nose and the rudder servo had a strong chemically smell (earlier during my troubleshooting, I thought that there was a smell coming from the receiver). So for now, I have ordered a new servo from Motion RC. I will provide an update on how it goes.Comment

Everything works correctly now. I installed the new servo for the rudder. However, with all servos and ESC connected to the receiver I couldn't get it to bind. Actually, once I connected the battery to the ESC, I heard the 3 tones and the receiver light blinked a few times then went out as I was trying to bind. It did not bind.
I then disconnected all servos and tried binding with only the ESC connected to the Rx. It worked and bound right up within a few seconds. I then connected the 3 flight control servos. Everything appears to be working.
I use the same Tx with several airplanes. I wonder if I will have to bind in this way (with only the ESC connected to the Rx) each time I bind to this Inverza. Time will tell I suppose.
this was quite a project and a learning situation for me. Thank you for all you help.Comment
