help victory speed control not working

[Rex R]

ok I've read the manual...it sounds like the esc isn't getting a signal it recognizes. so forgive me for being simplistic, but I know all to well how easy it can be to focus in one thing and overlook the (in hindsight) obvious.
boat set-up
make sure that the esc is plugged in correctly(with my futaba rx the darkest wire is nearest the outside edge).
if your esc is equipped with a 'battery elimination circut(bec) skip the following
is the rx pack charged? plugged in? switch on?
main motor pack charged?(and hooked up correctly?)
Tx set-up
good batt.s?
(radio 101 the majority of esc's consider futaba backward) so throttle reverse ON
and one that gets a number of folks, throttle trim set to Negative 30(or so).
if after reviewing all of these things etc. the esc still doesn't work, call rc-hydros and tell them.

I had a problem setting up my spektrum to an MGM esc, I had to set the EPA to -125% for full throttle and set reverse to 0%. it took me three weeks and a few dozen emails /phone calls to get it to work.

I have a similar problem with my RC Hydros Victory 60 amp ESC. I also have the Futaba 3PM radio. Initially my ESC arms and works normally for a few minutes and then dis-arms (LED flashes red) and I can't re-arm it again for a long time after. I have ruled out all other possible causes (if something were obviously wrong with the wiring or connections it wouldn't work at all) - the ESC is not functioning properly.

Give Andy at rc hydros a email to see what he says.

Also, in my case and probably yours changing transmitter settings is not the solution to the problem. Even if you haven't reversed the throttle the ESC should still arm and not be blinking red. The fact that it's blinking red means it isn't responding to the radio system.

My only choice is to send mine for replacement or repair. I hope your problem is just a simple thing but it sounds a lot like mine.

I have been communicating with Andy about this for a little while. However, I was able to recreate this problem on the bench last night and have emailed him an accurate account of exactly what's happening. I'll see what he says.

I recall reading (somewhere) that the futaba's signal is a little strange(compared to the rest of the radios) apparently the nuetral setting coresponds to about 25% throttle...while a fair no. of esc's can cope(programed to accept it) there are a few that do not(castle, mgm, and aq's sv esc). thus the need to set the throttle trim down to a point that the esc recognizes as nuetral.

actually changing the settings may be the solution to the problem. My spektrum would not even arm my MGM brushless esc, but it would arm instanly with my Airtronics MX3, My solution for the spektrum radio was to change the EPA adjustments, now the esc arms all the time every time. A big thanks to "FLUID" for helping me solve that problem. the settings were -125% for full throttle, +125% for reverse. didnt make any sense to me either, but it works!

[QUOTE=Jeepers;5276]try setting your end point adjustments(EPA) to 125% full throttle, (or what ever the max epa is on your radio) and the brake all the way to zero.[ QUOTE]

this is what I had to do to get my victory to arm, and I just picked it up from steve a few weeks ago, radio is an Airtronics MX3

[GregS]

Thanks Jeepers. I think you might be right about the EPA settings.

My problem is a bit different from not arming at all. It arms and works properly initially but after a few minutes I start having the problems with it dis-arming. Sometimes it re-arms and works briefly and then dis-arms again. Somtimes it won't re-arm at all. After leaving it for a long time it will re-arm and work normally for a few minutes again and then the cycle repeats so there's a timing issue.

What I observed last night in my bench testing is when I give it full throttle in the beginning the LED light is full green which means the ESC is giving full throttle. After about 30 seconds the yellow LED starts coming on as well indicating part throttle despite the trigger being full on. I'm thinking the part throttle being on too long may be causing the ESC to do what it's doing. If I adjust the EPA maybe the ESC will stay at full throttle and this dis-arming thing won't happen. I'll give it a try.

What about your reciever battery dropping voltage too fast?

My understanding is the receiver battery is only powering the receiver itself and the steering servo. I have the red power wire for the ESC disconnected to disable the BEC. The ESC should be powered by the main batteries. Andy suggested there might be a problem here with bad batteries and voltage drop. However, the batteries are in good shape and the same thing is happening with other batteries as well. For the receiver pack I'm using 4 new Duracell AA which I've tested also so there shouldn't be a problem there.

Excuse me in the first post you say it is a 90 amp ESC. In the last post you say you have pulled the red wire to disable bec. Well one problem here is he only makes one BEC ESC and that is a 60 amp version. Put the stinking red wire back in if it is truely a 90 amp.

Your getting confused with the other person that started the thread. His is 90 amp, mine is 60.

That is why you don't hijack someone elses thread start your own
