    Haven't had a chance to get video but was able to test today with a different setup. I used a 36-50 2300kv motor, 60 amp seaking, 4000mah 3s lipo, and x435 prop. After 7 minutes of stop and start running, temps were all under 85. I think this setup is a winner. Way faster than 2s on the 2900kv motor. Can't wait to test my Grim 36mm, I hope I can get a few more mph without torqure roll. There was no torque roll at all here but I am running a tad wet. Need to find the right CG and get more 3s batteries!

      Interesting about the 3S set up being better, bears out the saying, more volts less amp runs cooler.

      Curious to hear how the Grim 36 will do.

        Alright had a chance to take some video the other day. It was 52 degrees outside and no wind. Ran the Rio for over 12 minutes on my 4000mah 20C 3s lipo and there was still more in the pack. All temps were around 90 to 100. Got my grim prop which I will try next, this vid is with the x435. Tried moving the battery back but boat is still running too wet for my liking. I have room to move it back so I think I'll try that next. Also, ran my Supervee 27R which is in the vid as well.

        Might go back to 2900kv on 2s with the grim prop and see how that runs. I have had a lot of fun messing around with this boat. Its held up well.
