    Is it pain for the boat to jump/driving in choppy water and re enter with trottle?

    Hi. I got a question about driving in rough water/choppy water with waves, i trying my pro boat miss geico on 5s today out on a water with some waves, it was not easy to re enter the water without having trottle when it lands in the water, it happens a couple of time..
    It was waves because of the wind was blowing a bit..

    I know that with rc cars it hurts the driveshafts if you jump and landing on the floor with trottle and speed on the tires, it could also break the differential if you have a bad day.

    How is it with rc boats when we came to this situation there you try to speed up the boat where its a little waves, it not easy to not re enter the water without have a lot of trottle when the water is a bit unflat.

    So what is your thought and experience?

    Thanks for reply :-)

    People do it all the time, sure, there is stress on the flex cable, it tightens up when the prop is in the water and when the prop is out of water it will "loosen" up under no/light load. Also when the prop is in the water and pushing the boat, there is thrust force on the motor bearings, so when it is out of water, the load changes.
    The motor will spin faster when the prop is out, then forced to slow down once the prop is in the water, during this time there is also changes in the torque, if you think about it, any changes in torque will have the motor mount flex which will flex the hull some what, too much to think...
    Then there is electrical current to be considered, the spikes you will see on a data logger will tell you sudden changes in throttle and rpm...
    There are other factors to consider but...
    But, don't let these bother you, have fun!
    Too many boats, not enough time...
