180a ESC & signal loss = 100% throttle, I found the answer!!!

[tlandauer]

This issue is in regards to the Seaking/Turnigy 180a ESC, its the combination of that ESC and the cheaper 3 channel Tactic and Futaba receivers that have this "glitch" in the programming.

I don't think the Aquacraft 60a has this issue.

The Seaking 180a and Tactic is a common combination for a lot of people. Usually Revolt 30 or Motley Crew owners who upgrade their motors and ESCs from the stock systems but keep their stock Tactic radios.

Yeah, I realized now. I only used the Aquacraft in combination with the Tactic, on my Seaking180 I had always used Spektrum marine series.
I am sure it is slightly different in nature with regard to my situation.

Why don't you give us some more detail about your situation, maybe someone has an idea. Are you running the Aquacraft 60a ESC and losing contact while the boat goes 100% throttle?

I've seen it happen, but it was usually water in the receiver due to bad taping job.

Thanks for your interests, I actually posted this sometime ago.
Yes, running WOT and lost of contact between tx and rx. Rudder is rendered useless, boat goes at whatever last direction it was headed ( usually straight to shore, lol....) but it seemed to me a range issue, it duplicates itself at the exact location. My tape job is usually quite good, so I ruled out water as a cause.
Edit: the usual response was to get a better radio.

Actually, you will find the opposite from our group. We love Tactic, I haven't switched myself because they have been so rock solid for us. We are a group that also runs exclusively in ocean water, which is much harder on electrics.

We actually have had members move back to Tactic from more expensive systems because they preferred the reliability of their old Tactics.

I have no qualms with running Tactic on my 85 mph boat.

For the issue you are having, did you try a different receiver in that boat? It could just be a faulty receiver, I've seen brand new $125 Futaba receivers go bad.

The Spektrum receivers have a failsafe. The default is concerning to me and I was scratching my head on this for a while this summer when my mico-eco would always take off after i sub'd it.


Failsafe
The MR200 features Preset Failsafe that is ideal for most types of boats. With Preset Failsafe, when the signal is lost all channels are driven to their preset failsafe positions (normally low throttle and neutral steering). Failsafe positions are set during the binding process (see step 3 of the Binding section).

Failsafe Operation if Receiver Power Only
• When the receiver only is turned on (transmitter is off), all channels have no output, to avoid operating or arming the electronic speed control.

Failsafe Operation After Connection
• When the transmitter is turned on and after the receiver connects to the transmitter, normal control of all channels occurs.
• After the system makes a connection, if loss of signal occurs, Preset Failsafe drives all servos to their preset failsafe positions that were set during binding.
• When the signal is regained, the system immediately (less than 4ms) regains control.

This was pretty much my exact scenario...........other than losing contact wasn't location specific.

A simple check would be to power everything up and let the Tx and Rx connect. Then power off your Tx while leaving the boat plugged in to see what happens. If the prop starts to spin, rebind with the Rx but don't move any Tx controls when you do.

I sure did, bought 2 new ones and I regretted doing the experiment because it was those two that had me repairing the boat. (UL-1 and a Vacu-Pickle hydro).
Now, I must say some of my 2010-11 vintage rx didn't have that, so could be a bad batch??
Anyway, i still have few and I just watch where i go and try to stay out of the troubled spot for now.
Thanks, i also like these for the same reason as you guys do.

Well, yes, I did that and it stopped, however it was a different story once it was on the water and in that area.

That doesn't make any sense. What that implies is that there are different type of brown outs.

Rick, you are absolutely right, that's why I gave up, not worth my time to dwell on it.
As I said earlier, when I was just getting into FE, around 2010, I had range issues ( was in a different area of the same lake, boat was really further away than the average distance i ran, didn't measure exactly how many feet or meters though). Each time when it happened, the boat would stop until I walked closer and re-established contact with the rx. Those receivers were bought then. The newer ones were bought last year (2014). all three of them had consistent behavior.
