Fail safe

[dionpeter]

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.

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!

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..

its doesn't quite work like that. the fact is if the problem goes away
(temporary radio interference) then you can drive your boat back to
shore. if the problem gets worse then nothing else will happen the fail
safe will keep the boat at idle. providing the boat has a clutch it will
remain still.

this could all be Irrelevant if you have no clutch then the engine
should shut down.:)

If the engine is stopped and the engine runs,there is no cooling
water(unless there is a water pump or something like this)and the
temperature becomes too high?Why somone have to do this to his
engine?there is no possibility to bring back your engine so why you
have to "destroy" your engine?I prefer to follow the "K.I.S.S."
theory:)
And if there is a PCM receiver the fail safe must be fixed with engine
off and a little rudder(the boat slows down more quickly)....

ok you got me there i forgot about the water cooling your right that
would be a problem unless your running a seperate water pump. i think
that what we can say is that i depends on the boat set up.

and it depends on what you think the fail safe is for? to stop damage to
the boat or to prevent injury or to prevent loss of the boat?
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

so do I :-)

a fail safe to me should "fail safe" i.e. cut the motor completely

I talked with a friend who has a giant scale Ultimate 46% and he told
me that the most safe adjustment for the fail safe, is to make the
plane to do a flat spin..That means engine off,up elevator,right
aileron and right rudder!!the movements must not be full...Just for a
flat spin so the plane falls slowly to a specific place that you can
see it!!
But let's not continue this discussion any more...It's a BOAT
