    Brushless esc's perform best at full throttle, u will blow a cap if your cruising around 1/2 to 3/4 throttle all the time. Its a fact

I am just scared no matter what esc to plug in my packs and not be full throttle until it hits LVC.

      Yea, it is different than Choppers,, But you can run on/off throttle with a "good" setup in FE boats.. I race everything from 4s to 10s powered boats from 32" up to 44"... Racing you always are on and off throttle,, getting in and out of traffic and slowing for turns.... It is all about the AMPS your setup is pulling and how long you run..

      Your problem is the KV of the motor is WAY to high for a 4s set up in that mono... I would recommend a 9-10xl and M445-M645 prop,,, that will give you great speed, cut down on amp draw and be easier on the lipos...

      These ETTI esc's work fine when setup with the right motor, prop, and hull combo...
      Nothing like keeping you lipos warm and your prop wet!!

        It's my understanding that ESCs are most efficient at wide open throttle. Once you are at partial throttle the ESC has to do a great deal of inefficient work to manage electrical Pulse Width Modulation like 30,000 times a second resulting in heat. In my opinion, if you build your system to 80% capacity and watch your temp through logging or telemetry you should be okay to drive at partial throttle and handle that inefficiency.

        To explain blown capacitors, I would suspect that over propping or running a high kv motor leading to excess peak amps. Have any of you guys with failures checked your amp rate? Just curious.
