Anyone else trying to get a hold of hobbywing via e-mail having any luck. I sent a message 3 days ago and nothing..

I have a brand new 120A that the programming does not work on and getting no answer is very frustrating

If you are going to make the reverse delay selectable, maybe you could put 0 delay as one option. I have the Xtreme Stock on my scale crawler and the reverse delay has caused several rollovers that could have been saved with instant reverse.

hey guys... I just stumbled onto the end of this thread and what I have to say may or may not be welcomed by everyone, but I'll try anyway.

First, I love Hobbywing products, and after having tried almost all brands of brushless motor/esc combos out there, all I will buy is Hobbywing. I can say with 100% certainty that there is an occasional problem with some of the Hobbywing ESC's regarding braking. I have 5 Hobbywing 80A xe-run ESC's, and 2 of them have the reverse problem described by a few people in this thread. Let's say you are nearing the end of the straight away, and use the brakes to bring the speed of the car/truck down, then release the brakes and realize you would like to drag the brakes a little more, the ESC will immediately send the motor into reverse. 3 of the XE-run 80A controllers I have don't do that. The units that have that problem have always had the problem regardless of which firmware and which tx/rx combo is used with it. The ones that have never had the problem are the same(they have never done it regardless of the firmware or tx/rx combo).

On the speed controllers that have that problem, it will do it 100% of the time and is very very easy to reproduce. If you let off the throttle, apply light brakes, let off the brakes and return the trigger to the neutral position, then apply light brakes again, the motor will go into reverse. If you apply slight throttle after letting off the brakes and then apply brakes again, it will work correctly. That's the only way I've ever been able to get around the issue.

Disabling reverse in the ESC will eliminate the problem, but sometimes people want reverse for bashing (I know this is a thread regarding these ESC's in reference to racing, but thats fairly irrelevant for the purposes of this message). I tend to think that the problem actually lies in the hardware as apposed to the firmware. I have had friends who have used the same controllers and not had the issue, and as I stated earlier some of mine don't have the issue either. The problem, however, absolutely does exist and is a serious flaw in the speed controllers. Take for instance a monster truck, with the large tires and high torque of the motors, drive shafts and differential gears are often broken when a vehicle goes into reverse while still moving forward. That is one of the major reasons they put the reverse delay into the controllers in the first place. Coincidentally, none of the 10th scale Hobbywing controllers (25A 30A) i have have ever had this problem. I have a new 80A XE-Run ESC that i haven't opened yet. I'll have to see if it has the problem or not.

With all of that being said, I will continue to buy and use the Hobbywing products that I never have to send in for repair and happily let the people who buy the more expensive brands keep sending theirs in for the free "warranty repair" and wait for the replacements to be delivered back to them, but thats just my choice and isn't necessarily the best for everyone else.

It's people like you that stops things getting developed. I and everyone else that have issues will all try our best to agree with you from now on. But for now don't comment on my post from now on.

hoobywing v3 in action ....http://v.youku.com/v_show/id_XMzE1NTUyOTc2.html

FDR 6ish
DDRS 9
Boost 40
Turbo 24
Slope 24
Delay 0.1
ACC 250
(930 BTW)

Hope it helps

Some radios's have issues with ABS that can cause this effect, switch off ABS tends to sort out glitchy bits too

Disable reverse or don't double tap brakes when running, I have run reverse forever and the only issue I have is that the car tends to hesitate after reversing around the start line.

Reverse was only kepy in for the use of bashing a leftover from the ezrun stuff, chill out buddy :)

Have been away from my computer for a couple of days, got the messages along with 40 + others am in the process of migrating the shop to a new ISP so will reply to code requests shortly.

@cherry2blost

thanks for the help!

Awesome track... Where is it?

In relation to a xtreme stock speed controller, running 930 firmware, what degree does the timing (option 9) values equate to. There are 60 steps, looking at the old setting there appears to be max of 30 degrees timing that could be applied, does that mean there is 0.5 degree per step (60).

WOW--those cars are quick and that's an AWSOME track!! Love to see one like that here in SoCal!!!

Me too ;)

Thanks for the video and rave music :p

oldnood .. thank for sharing video .. what turn motor the V3 running?
