Hi I have just been given an Mtronics viper eco20 no packaging so no details will this run in a boat and what amp fuse should I use to protect it from over load
Thanks for looking Yours Scout

Eco20 will be a 20 Amp unit.
 I would suggest a 15 or 18 amp fuse on the motor side.

Hi Scout,  For full details look up the Mtronics site tells you all you need to know.

Tell a lie, it's a 20 "Turn" unit (refers to the maximum number of turns on a standard "540" motor.
What that translates to in Amps, i really don't know.

Scout,
What motor are you wanting to run this with?

20A continuous,300A burst,150A reverse is what this little esc will give you. Mtronicts recommend fitting a 15A fuse for this unit.

Personally I would fit the fuse in the supply.  ESCs often have current limiting to protect against overload coming from the motor, so a fuse there really doesn't do a lot (unless there is more than one motor).  A fuse in the battery lead, however, protects the boat against an internal fault in the ESC.

Good point Malcolm!
 I guess having a working servo isn't much use unless you plan to 'paddle' it back to shore!
