    This is not correct. In stock form, the props on the Zelos spin inwards. That puts the the cable marked with an R on the left/port side of the hull.

    As previously stated, the cable marked with an R gets installed on the left/port side of your hull. When both installed, the winds of both flex cables will make a ^ pattern, pointing towards the bow.

    Just finish putting the zelos together again and align the flex shaft. My question is if it will be and advantage if I change the motor timing , im running 45 mm cnc props.
    And what will be good.
    No. 7.5° is faster and the motor runs much cooler than on 15° on the 3910 motors and if you have the 3831's Team Orion (who manufacturer's them for Pro Boat) tested these to be more efficient on 7.5° and only recommend 7.5° timing for them. As for the flex cables please install them as I initially recommended in my above post and you will be fine. Good luck with it!

      Here's a great picture Rafael Lopez posted earlier today, just for future posterity when someone else is asking about flex cables...

          Or put wire drives in and don't worry about it.

            you say run faster does motor not normal run slower whit lower timing. ? I agree it will be running cooler. But I have not testet it yet so maybe giv it a go.

                Depends on the motor, it's not a blanket statement. More often than not, running more timing than what a motor was designed for does nothing but create more heat.

                  Lower timing is when the ESC fires the coil late (when it’s real close to the magnet) and that will slightly reduce the Rpm that the motor produces but the torque will be slightly higher. Higher timing the ESC fires the coil earlier (when it’s still further away from the magnet) so that's going to increase the motor’s RPM, but slightly reduce it's torque because it waste some of it's energy by striking or firing early or to soon. Be aware that higher heat comes with higher timing in most cases. Good luck with it

                    Dynamite 3831 6-pole, 2000kv motors are a 1.5 "D" wind
                    Timing should be 0 to 5 degrees MAX.
                    Higher timing on a "D" wind does nothing for RPM or torque only causes more heat.

                    On a "Y" wind motor higher timing 10 to 20 degrees MAX will give you more RPM with less torque.

                        OSE has just liner material. The metric version will be slightly smaller, so it should work ok.

                            I cannot find right size on OSE website. ??

                                I’ve used the 3/16” liner on a metric shaft before. But if you’re concerned about sizing, why not change the stuffing tube and flex to an SAE size? I’ve eventually have done that on all my boats, when the flex cable gets worn.
