    Question: I have a Castle 1520 and as you know it comes with cooling fins on the can; do you think it could run on the Stiletto without water cooling?

    Temps around here are in the 60F these days, would that be enough to cool it down?

    Just wondering....

      I think it would sink. Can you fit 6s in that hull?

        I have 3 flexshafts from PB, they all look like that.

        You might want to buy the Hyperformance 3.5 flex shaft instead.

        BTW, when I turn my PB flex shaft in the OB without motor installed I don't have much resistance, I'm sure it's better with brass tubing instead of teflon, but it's not as bad as you described. At least on my unit...

          I think you're right!

          There is a LOT of space for batteries: it's 60mm wide and 65mm deep, minus some space for the "hatch".

          I haven't checked the length, but you can fit two 145mm long batteries end to end. So it's at least 29cm long.

            Oh wow!
            that motor on this hull possibly would not need any extra cooling

              I don't really think I'm going to do it... Rumdog is right, the whole thing would probably sink!

              But it would be fun to try!

              And BTW, the pond where I usually run is only 4 feet deep. It would be easy to retrieve from the bottom...

                    Yah, mine is pretty hard to turn. I think brass is the key. I think its because of the sharp bend. If you think about it. Why teflon anyway? Its on the inside of the case so it isn't necessary for keeping water out. If you can imagine even a slight bit of resistance when turning by hand is gonna be huuge when the motor is trying to turn that prop shaft @ 30,000rpm.

                      Yo GP73;

                      Hopefully you plan on joining us on some club races next year in TO and Kitchener, if you do, then concentrate on 4S setups so you will fit in the OPC class. Tunnels are a drivers boat......

                        Oh I know, you mentioned it before.

                        Not sure if I'll ever race, just having fun for now.


                        Just adding something here: A Stiletto with a UL-1 motor and a single 4S 40C pack would be legal for racing?

                          Darin, can you confirm the outside diameter of the brass tube that you used to replace the teflon. In one post you stated a .187 cable fitting snug inside, and in another post you said you thought you used a .250 flex inside the brass. I'm thinking its 7/32 o.d. but want to be sure.

                            It's the first one... the .187 cable size... It's a little bigger than actually needed for the .150, and the .187 fit, but snugly.

                            Sorry for the confusion....

                              Yes! P-Limited (or P-Spec) OPC Tunnel... Should rock!

                                Can anyone say what happens to runtime when using a UL-1 motor and a Grim 42x55 prop?
