What cause slow speed?

[The noob guy]

Any device to test if motor runs at full speed without put the boat to water?

You can hear the change in rpm anywhere. This is a simple procedure though and can be done at the lake.

[The noob guy]

I can hear the motor from slow to full speed but I guess the full speed I currently have is not full speed. I put a 4082 without connect the shaft so I can hear the rpm only and I can tell it sound different than my zonda at full speed without the shaft connected.

Does reverse sound louder than forward?

[The noob guy]

No, reverse sounds a little bit less powerfull. Bought a different controller to test it out this weekend.

[eehess81]

Perhaps the motor is faulty. Have another comparable one to test with that setup?

[The noob guy]

Tested on both sss 4082 and turnigy 3674. Either is controller or esc.

[eehess81]

Is there a programmable power output setting on the ESC perhaps? Should come at default full power but have had escs come in non default settings

[eehess81]

Have another ESC to test?

[The noob guy]

Is it possible because I use an adapter from 3.5 to 4mm on the 3 wires for a esc to motor so motor does not get enough power?

Update: finally get the boat back to action after I change the esc to flycolor. Anyone know who sell 4mm flex cable with 4.76 bore so I can use 4.76 prop?

Have you had a look in the OSE store here for parts?

[eehess81]

OSE sells .15 cable with 3/16 prop shaft, .15 slightly less than 4mm but close. 3/16 is 4.76 mm
