Model Forum / Radio Controlled / Water Models / April 2007Fail safe
I was wondering what to set my fail safe at. Would i have it stop the engine all together which would be pretty safe or sit at idle in case the fail safe is just being over sensitive? Thanks in advance.  Signaturedionpeter it depends if you have a clutch and where your using it. if you have a clutch and your using it in the sea for example then i would say idle would be best that way if its just a temporary loss of signal you can still bring the boat in once the signal is regained. but if you have no clutch and your boat is pointing out to sea that would be bad as if you dont get the signal back then wave good bye! so you would really need it to switch off the engine in that case so you dont have to swim to far! Signatureal6600 when the fail safe is activated,there is a problem....so the problem maybe become worst...also is almost impossible to take control again so the most safe way is to turn off the engine so there is no broblem!!! sorry for my engilsh... good run..

I would have thought the best thing would be to shut the motor completely off as a purely safety measure. when used in a plane you would set it up to do the least damage to another object, IE shut the motor off and have a little up elevator to slow the model down and all other controls at zero, the object being is not to save the plane but to prevent injury or damage to a third party funfly3;446 Wrote: > I would have thought the best thing would be to shut the motor > completely off as a purely safety measure.

But let's not continue this discussion any more...It's a BOAT forum!!:cool: Signaturev_tolias v_tolias;461 Wrote: > But let's not continue this discussion any more...QUOTE] > > probably a good idea as we seem to have scared off dionpeter who > started the thread. :rolleyes: Signatureal6600 |
