Setups

[Brushless55]

Jeff,
Thanks for all the tips! Unfortunately, when I went to try my new batteries, I found out my port sid ESC is not working. I get power to the receiver, the rudder works, and starboard ESC works. The ESC is supposed to beep 4 times for a 4s battery. The starboard side ESC beeps, but the port side ESC does not.

On other parts of this forum, I think I saw that others have had problems with these stock ESCs. Guess I'll have to see if Venom support will send me another one.

Swap out the escs connections left to right and see if that helps..

Ran my new setup a few days ago.. Etti 150s, Turnigy 2300kVs, 5S, 442 props..
Runs extremely fast. Will need to alter the CG some more to keep it pasted to the water..

Troubleshoot the Y-harness to see if its a bad connection keeping the ESC from arming. Thats another possibility and simple to check.

Ok...I'm awake now. Got a little busy. I tried everything mentioned in this forum. Swapping the power and receiver wires made no difference. The port ESC still does not work.

The port ESC is the one that does not work, but it also provides power for the receiver and rudder control which work fine. Even the starboard ESC works fine even though the power for the receiver is coming from the port ESC.

I got in touch with Venom support yesterday. They told me to send in the ESC. I've seen ESCs fail before, but they usually pop, explode, catch fire, or at least smell like burnt electronics. This one has none of those symptoms. It is strange because I never used more than 4s and its rated for 5s and some have even tried 6s (although there is note in the documentation now that says don't run at 6s).

Remember that just because it is rated to 6S doesnt mean it will handle 6S with any motor. a 2850kV 380 motor will require alot of amps to move such a big boat. I kind of wish I had my amp meter hooked up when I ran 3S with the 442 props, but Im sure it would have been right at the 60amp (or more) limit of the ESCs.

That sucks..
I'm sure you have checked the motor connectors on the esc to make sure the have a good solder job?
If it is a bad esc, I hope very much it does not take long to get a new one

Oh well.. Just a $30 motor...

[Rumdog]

nice and fast! Try lower kv motors, some proboat motors would rock in this boat on 5s!!

[NitroVal]

Yea, I gave these Turnigy's a try after following that thread that mudl made about his BJ26 doing 80mph on a set of 2600kV on 5S... Im starting to wonder how he did it...

[RCprince]

2 different hulls and setups

[NitroVal]

Not that far off.. He has 8" less than me, and possibly better ESCs, but more motor. My motor flew apart and its only 2300kv. His stayed together with 2600kv. I think its a matter of motor RPM more than motor load. Im actually a little surprised. I thought these motors would last a little longer that 2 runs. Its turning almost the same RPM as the stock motors do with 4S.

[RCprince]

The 2300 may have lower kv, but I will doubt the torque is greater than that of the 2600, since the 2600 has a larger rotor = larger magnetic foot print.

[NitroVal]

Well thats my point, the 2600kv would have a larger rotational mass and higher centrifugal force, causing it (in theory) to come apart faster than a 2300kv at the same voltage

[Brushless55]

BJ motors on 5s or even 6s would rock
