Hi all, I'm trying to help a club member with his esc problem, at least, I think it's the esc.
His set up is
Planet radio system
2 Graupner speed 600s
Tornado 50 amp esc
7.2 battery pack
The problem is that we switch on, wait for binding. Rudder works fine
Run the motors, works for a few seconds and cuts out, usualy after going from forward to reverse, then they stay dead until we switch off then on again.
We checked the receiver by swaping chanels, no diference.
Checked the batteries, fully carged and checked on load.
Checked the shafts, 1 was very tight, aha I thought, drawing too many amps and cutting out. Disconected both motors from the shafts, tried again, same problem.
I did find some poorly solded joins to the motors, he is re doing those before we try again.
The rudder keeps working throuout, so not a radio problem.
What am I missing? All help apreciated.
Chas
