The learning process continues on this end......for those of you who have been unfortunate enough to have a 4 in 1 go bad...just what do the little things do {symtoms} when they have had one too many, body shattering crashlandings, tree trimmings, truck antennas that jump in the way, neighbor's mailbox in the wrong place or just plain out of control, headed straight for the garage, do something quick, hit the ground and slide under the wife's car, boom breaking, flight terminations?????

Well for me, my driver outputs failed slowly. I have only had one 4 in 1 casualty so far...and
for me, it started toilet bowling (TBE) and then all of a sudden I was rotating to the left.
So I thought I had a motor going bad. I had some new motors in the wings, and put them in.
It was doing the same thing. I had my proportion gain turned all the way, and the trim all the way,
and I still had to hold the stick like 1/4 of the way to keep it from spinning. And one of my
motors was getting hotter than the other...(duh).

Replaced the 4 in 1 , set the trim back to 0 ...throttled up.....straight up in the air...no proportional gain needed.


And that is the only one I have had a problem with. Still going on the 2nd.

Just one man's experience.

Well I guess you said , "what happens"....

Solid state stuff seems to short (full on) although not always in this state..


Full on--shorted.....output is no more, it is basically a wire.

Then the next option is.
Open....nothing happens.

OR intermittent ...just flaking out some of the time.
Which of course is the hardest one to diagnose.
