Hello so just replace the esc in my boat and now it seems slower. I didn?t change anything else, same battery?s motor and prop. Re calibrated the radio many times with no prevail. My old esc was a dynamite 120a esc and nothing was wrong with it yet but I swapped it out for a raider 150a esc for better efficiency and reliability.
Boat proboat ul19
Motor dynamite 2000kv witch I believe is a d wind
Battery?s 2x2s in parallel. 5000mah 50c
Same stock prop
New esc raider 150a
During the install the timing Was set it at 7.5 from the 15 degrees and also I added new connections to the esc. I did remove the 6mm connector and install a ec5 for the time being till I can get better connectors. Then I took it my local lake for the first test run and found it to run slower. I didn?t have a speed gauge just from the sight and sound. Before there was a high pitch sound during wot. Now it seemed less. When I came back to shore after a few passes to check the system out I noticed the battery?s were warmer then normal and the battery to esc connections were warm and esc also the bullet connections to motor.
To add during install I added new esc connections and butler connections at the motor and I ran out of my solder so left and pick some up. At that moment only kind I can find was the silver solder style for electronics. Not the 60/40 kind. When I did solder the connects I will admit they were bad. Problems getting the solder to tin into the wire leaving exaposed strands of wire to connections. I was also trying to do all this late at night trying to make the next day for testing as it?s the only good day of the week. Next week it?s all rain and windy. After my test run and what I have noticed I did redo all the connections of solder with 60/40. This time around the solder flowed into the wires and the connectors. Then last I reset the timing to 0 seeing if that helps too. So only theory I can think of is The poor Solder job and having high resistance. Right now the weather is really windy and raining so I can?t go out and retest it. So it?s driving me nuts and maybe someone can shed some light on the subject. Thanks
