Riot Problem

[Airpaddler]

Have aquired a used Max Thrust Riot. Has the classic syndrome of going to full revs if the TX is inadvertantly shut off. I have no programming knowledge or ifo as concerns the standard ESC on this model. Could anyone advise please as only have a few fingers remaining!!!

Hi Airpaddler, we can sort this out I'm sure.

First of all.

1. Take the prop off!

2. This sounds like a radio failsafe setting. Which transmitter and receiver does it have? Makes and models.

[Airpaddler]

Chris - Forgive my crude humor. The prop is off. - Spectrum TX is dx8 and Rx is AR6210.

Thanks for help.

No probs AP, we do get the odd one on here that does need telling that.

If it's Spektrum, then your problem should be cured by going through the bind process again, but with the throttle stick in the low position.

It's always a good idea to bind a model, sort out your channel directions, throws and everything else, and then finaly set the failsafe, which in the case of Spektrum gear is set by binding.

Hi Airpaddler, Make sure the throttle trim is set to '0' too when you do the rebind or you may still get a few revs from the motor even if its in failsafe mode. I have also assigned the mix 1 (back right switch) in position '1' as throttle cut with its setting at -5%, which is what we tend to do with rotary wing craft as an added safety guard, plus it gives you the option to practice dead stick landings.

In my experience that can all get quite complicated Barry.

If you have a switch setting that's -5%, then with many ESC's, if you happen to have your switch in that position when you connect the battery, it will take that position as zero throttle. Then, when you pot the switch in the normal position, you have a permanent tickover that the throttle stick can't stop.

If that's what you're intending, then fine, but it's an added complication that could lead some into danger.

Thanks Gentlemen - Have carefully re-bound the RX with a completely clean model channel on the TX.

Appears to have solved the full power prop problem.

However ESC (O/E Century 40A) will now not stop beeping @~ 1 beep/sec.? Suspect it may be faulty as it does not seem to do a cell count correctly.

Control servo`s all work as they should?

You might have to re-callibrate the ESC. Turn the Tx on with the throttle stick fully up (prop off of course!) when you hear beeps from the ESC pull throttle stick fully down.

[Airpaddler]

Tony - I suspect that in my inexperiance. This is how I got in trouble in the first place. Trying to emulate the setting of previous ESC`s?

Will I pull back on the throttle after a certain number of beeps. Lipo is 3 cell.

[Airpaddler]

Thanks guys, I have gotten there!!

Answer was to let the ESC play its classic "DOODLE UH" with the throttle fully forward, allow count of the next three slow beeps. (I assume that gives 3 cell recognition) Pull back on the throttle and "bobs your uncle"

Obliged to all for your input.
