Hi folks,
Apologies to a couple of folks who responded to my
original message. Due to family visiting over the holidays I
couldn't respond to you in a timely manner. Now when I got
on the computer some of the messages dropped off due to my
browsers setting for message retention.
I believe one of you was named Umi. I read your message
and wanted to respond but now I can't as I no longer have
it.
Update: I returned the ESC as I wasn't sure it could work. I
need an ESC that is designed to be used without an on/off
switch. It also needs to be able to handle at least 23 amps
continuous. Or 19 amps if I use only one motor. Those are
the measured current draws I determined today by putting an
ammeter in the circuit and running the boat under load on
the lake.
My setup now consists of two RS550 motors driving a Dumas
3:1 gear reduction unit to a single shaft with a 3", 4 blade
Rivabo brass prop.
I could try to use a 4.5 to 1 reduction gear set instead of
the 3 to 1 on it now. That would reduce the load and
hopefully the current.
One thing I will try that was suggested is to put the motors
in series. Might make the motors go too slow but I won't
know until I try.
If anyone has some suggestions for me to try, please fire
away. I'll try anything reasonable.
Thanks again, Jim P.
