Re: Throttle cut using logical switch. (abandoned).

Ok, than you have solved the problem. The thing is, unless the switching point of the engine killer switch could be programmed, you couldn't use the throttle channel. If you could program the switch to switch at a given pulse from the receiver, then it could be possible to do it using the same chann...

Re: Throttle cut using logical switch. (abandoned).

I understood that it is a petrol engine, and there should be an ignition system that is controlled by the radio, just like on my plane

Re: Throttle cut using logical switch. (abandoned).

I have been following this thread and i got the feeling that there is some misunderstanding here. What I think he wants is: As an example, his throttle servo MIN / MAX movement ranges for example from -60% to say +80%. So at idle will be -60% He did a mechanical implementation with some kind of spri...

There is a MOSFET providing reverse polarity protection.
Then it shouldn't burn anything, providing that there aren't any design flaws of course ;) We have seen them before :P

Re: RC Switch, 4 Outputs on a Single RX Channel

Yes it is, or an arduino Pro-mini

I just had another look at the schematic I posted for using N-Channel Mosfets, and although I might have tested them I think there might be a problem. They might not turn completely ON. The P-Channel Mosfets will work. That is what I have built for myself..

The older D8 is more of a problem as it is not legal in Europe for new products.
But it can be used with an external Multiprotocol module, right?

Re: ERSKY9x Questions

The Atmel processor has a synchronous serial device available to generate the XJT protocol for the external module. The internal module connection only has a PWM device. It used to only do CPPM, but I did manage to get multi and DSM to work. It may be possible to get XJT to work but needs some new ...

I think the problem is that you would have to swap the "Physical" pins. Not just in software... :)

Re: 9XR Pro probs

Weird, the only thing I could think that it could mess up the programming like that is if someone changed the stick mode in the Radio Setup, but even that wouldn't change a control that was on a vertical stick to an horizontal stick.. this is what doesn't make sense to me :)

Hmm, don't know if I understand your programming, but it looks like you have the motors forward /Backwards on the left horizontal stick (Rud), and left/right on the right vertical stick :o That doesn't look right?

Re: ArduVoice-9x Voice Module with Arduino for the 9x Radio

The test version is stable, you can use it. Your radio doesn't have maintenance mode, and can't also play music. Those are features of Ersky9x that runs on more powerful hardware, not on the Atmega64 :) You might be able to get two extra switches connected to your voice module. Then you can configur...

Great.. Bad speakers can happen.. Or perhaps that one had a higher impedance, therefore the volume was lower??

be careful, I wouldn't use protected cells, specially in the models :) You are asking for trouble. You see, the instant power from the LiIon cells are much less than LiPos. meaning that there will be a greater voltage drop. if the voltage falls under the cell protection's threshold, the cell with tu...

Re: What else can I upgrade in my radio?

the problem with the 18650 cells, as far as I know is that they don't like to be soldered, and could get damaged quite easily.. I had bad experience with some from Banggood :( Not sure about those ones from HK.
