PostSubject: Ar500 won't failsafe?   Wed Oct 20, 2010 12:08 am

Sting has a pair of brushless drive motrs, and for some reason the friggin bot will not failsafe.

If I shut the receiver off with the wheels moving, they just keep moving???

Also happened with a BR6000 at Moto???

Any thoughts?

Thanks

I can't tell if they are just kidding around or not, so I'm gonna assume they are not . . .

If a BR6000 receiver is getting power, but simply loses signal from the transmitter,and your wheels keep spinning, then it is not an ESC issue.

If it weren't you, rjw, I would suspect a problem with the way the binding took place. But since you seem to have a good grip on that stuff, then in the case of the melty, I suspect a coding problem.

If you subsequently turn the transmitter back on, do the wheels stop?

I do agree that, from what I've heard, most "A" (airplane) series receivers only failsafe on one channel (throttle), and send out a 'null' (NOT zero stick) signal on the other channels for the reason that Kyle mentioned. So for that kind of receiver, on those channels, it WOULD depend on the ESC, because many ESCs will simply maintain their status through a null signal, just to 'get through' a temporary loss of signal. That's 'anti=glitching' stuff. What I do not know is if the AR500 is this type.

But the BR6000 (which has been discontinued, apparently) is supposed to go to the binding settings on all channels, and the new AR6255 is supposed to do that too (read the stuff in red on the linked page),

This can get misleading, because on some bots we use an SR300, with BB12-45 ESCs, and it LOOKS like it failsaafes at the receiver, but it's really just that the BB ESCs go to 'off' when they get a null signal. Also, the AUX channel either does failsafe, or the Castle ESCs we've been using have been set to go to "off' on 'null," because the weapons do shut down when we kill the transmitter.

This is NOT in a melty...It's in Sting, which has been converted to brushless drives.

At the moment it has 3 Castle Mamba Micro Pros in it

the bot used to be brushed drive motors with a Scorpion Xl and 1 MambMicro Pro for weapon.

And it did failsafe.

Now , it has 3 micro pros, and it does not.

No settings in software for escs for failsafe???

At fi, IT WOULDN;T FAILSAFE, SO I swapped in a BR6000 and is still would not.

I thouhg it migh be the esc endpoint/neutrals being off, but at the moment, they are perfect??

I have to try some other receivers..maybe the br I tried is flaky??

RJ,

Which ESC do you have all 3 wires running to the Receiver for the 5V...???

I've tried all of them, including 1 at a time, 2 and 3 all at the same time...no difference.

I called castle, becuse the 12 and 15 lbs drumbots have the exact same setup, but with mamba max pros instead of mamba micro pros, and they all work fine....Like Alex said, it's the escs and mamba has no answers except to say that the max pros are obviously better....duh... Rolling Eyes

I guess that I need to come up with a solution, unless the regular drive mode melty project is a success, in which case I could just use heli brushless escs, which would be re-coded to work in reverse as well.

I'm probably alone in that I don;t think that anyone else is using a micro pro in a comabt robot, let alone 3 of them......possibly the most expensive reversing esc of its size and still a total POS

Go figure..........

We used 1 last year and it failsafed fine...

I think it might be using 3 at a time......

Did they all set-up with full and reverse and neutral and blink and beep right?

We did have a problem setting the limits when we had some changes in trim last year..

Did you try it when all trims are set at 0?

other than that, I am really up in the air on this one.....

Maybe just a set up issue where spectrum never really ran 3 brushless motors on 3 dirfferent channels and tested failsafe in that configuration...

You used a Micro Pro???? for what?

Yes they all were calibrated properly...that's what I tought was the proble with the bot at FI....I ended up withdrawing it from the event...

May not be 100% relevant, but did you calibrate each speed controller on its own, without the others plugged into the rx? The Holmes Hobby SC's I'm using need you to do that to calibrate them properly.

We had one in To The Roof and One in Bar Exam....

They were running the E FLite Brushless Weapon Motors....

Confusion...I think that you are talking about MAX Pros....not Micro Pros

No problems with the Max....just with the little Mciro

Yes...1 at a time....still no go...it is for sure a mamba glitch of some sort

I think you are right..... I thought they were 1/18 but maybe not....

I'll have to look at them tomorrow...

I know the motors that came with them were 6900 and 4700..

I remember you bought a pair either max or max prso combs last year for use as weapon motors/escs.

they are 1/10th scale
monster = 1/8th scale
micro pro = little crappy 1/18th or whatever

So, MLEC had 5 really awesome bots at Belen today, and they all seemed to failsafe beautifully (and kick some bott too).

What did you do to fix this problem?

the failsafe problem is with Mamba MICRO Pros, not the escs that the bigger 15's were using.

the failsafe problem is only with MY little bot....Sting

btw: I tip my hat to you on making such a strong effort to get your bots ready and running. RE rocks....

If you haven't sorted the issue yet, give these a try- http://www.hobbyking.com/hobbyking/store/__11972__OrangeRx_R410_Spektrum_DSM2_Compatible_4Ch_2_4Ghz_Receiver_.html

I tried AR6116's and AR600's in my 30, neither failsafed right with the controllers as they just put out a null signal. the R410 and the R610(bigger, 6 channel version) failsafe to positions set during binding which may do the trick for you.

Price is right, although all my bots might be up for sale soon

Sorry to hear that. If I had more cash I'd be happy to give Sting a good home.
