    I need to run on 6s. I just bought the packs, are you running hydro 4060 1620 Kv on 6s? if so what is the prop specs?
    Thanks for your help in advance.

      Guys,
      Some people says 1600 kv will be slow, sohuld be 2000 kv. I am realy stuck in this 2 motors.
      Which one should I pick up?

      1- LBP4082-B/2Y 140A 33V 3500W 1600KV 0.0075 2.2A 7mm 20mm Φ5.0 485g with m642 prop

      2- LBP4082-B/3D 148A 25V 3500W 2000KV 0.006 4.5A 7mm 20mm Φ5.0 485g with x442 prop

        Go with the 1600kv. You can run either of those 42mm props for a good runtime and still prop up for faster speeds. Remember that the bigger the prop (as a general rule), = faster, but more current draw, which cuts down your runtimes.
        I ran a X447 at the weekend for two lap sprints and did a 31.29 on a measured course and I should be able to run this for heat races. An X443 is a little slower but does a 5-lap heat race with batts coming back around 3.8v/cell. Yes on 6s, revo silver series.

          Thank you for advices Peter, I am learning a lot. I use revos also.
          One more Q. to you.

          LBP4082-B/2Y 140A 33V 3500W 1600KV 0.0075 2.2A 7mm 20mm Φ5.0 485g

          in this specs, I understand that this motor draws 140A at 33V. So can I make a calculation like this:
          if this motor draws 140A at 33V it will draw 140x22.2= 3108 / 33= 94.18 A Than can we say this motor will draw 94A max. at 6s?

          Also I would like to know your opinion for Leo 4065-4068 motors? They draws less Amper, but can we use them in a hull like this. 4065 is 2000 watts, 4068 is 2400 watts.
          Best Regards

            For my 0.02, I don't get to hung up on what amps this or that motor might draw. I run and test so that I can do a 5 lap heat race and come back with around 20% left in the batts.
            Question, are you going to race 5 lap ovals or are you running the longer 5-6 min races? This will determine your motor choice even more. If you are running the longer races there then the shorter can motor should draw less amps giving you the longer runtime.

              I am going to install this stinger. Just need some advice on how to best setup the stinger drive to drive shaft.
              stgr2.jpgstinger.jpg
              The problem is if I run the brass tube inside the stinger, it does not allow me to adjust the stinger.
              If I leave the brass tube just out the hull there will be a gap which will cause leaking.
              What is the best way to install the brass tube and the stinger witout leaking?

                Hi kfxguy

                I really need your advice on this. Could you check the last message of mine in this thread?
                it is about the stinger installation.
                thanks in advance

                  I don't use a stinger like that in my builds. I use a strut with a flood tube. Offers much more adjustments.
