    prop suggestions for newbie

    hello, I have a tfl 56? genesis w/dual neu 1000kv motors, 200 ztw escs running 8s to each side (2x 4s 5000mah) I notice the electronics gets a little hot after 4-5min?s of running. I dont race boat, i just use it in my local lake. itheres octoba x457 props on there now. Can you recommend if these are a good prop with my setup. i dont run constant full throttle. thanks, mike

    just go to a bit smaller prop so that you can always go flat-out ,esc and motor don't like partial power(and get hot)however a runtime of 4min is not bad

          took your advice, ran the boat full throttle 90% of time, motors and esc actually ran a little cooler @120F but my batterie?s got up to 140-165F and one got swollen. Ran them to about 3.5V?s after 4 minutes time. the battery that got swollen has IR readings about 1-2 ohms per cell, dont know if it?s damaged though. the other batteries have about anywhere from 1-4 ohms per cell but look fine even though they got hot too. Wow, theres a lot of trail and error trying to get everything balanced to work effectively. Im looking for Dasboata for my new props and go from there

            You should not take your batteries below 80% discharge. They got hot and puffed because you over discharged them. If you want longer runtimes you will need to parallel in another set or use bigger capacity batteries.

              A resting voltage of 3.5 volts means the cells are completely drained, no usable voltage left. What is the LVC setting on the ESCs? A correct setting should have prevented this. As above, they are probably permanently damaged.

                Get rid of that battery, it is permanently damaged and could possibly cause a fire.
