Lehner problem

[Skipster]

I run a Delta 29 clone with
2 X 7.2 nimh in series

Octura 642 balanced and sharpened

Lehner esc and motor

The esc has no BEC so I have four AA cells for the receiver and servo.

I foolishly forgot to turn off the aux battery pack and left the boat
sitting for a week. Main batteries were removed.

I went to use the boat, replaced the dead AAs and
now anytime the trigger is pulled..

the motor turns at high speed and does not turn off even while
the trigger s released.
I must disconnect the main batteries to get it to stop.

I swapped recievers with the same result.

Did I cook the Lehner just by allowing it to sit with voltage applied?

Kind of new to FEs and thank all you fella's for your most
knowledgeable posts.

can't be a motor problem, must be the ESC or receiver!
try to swap each one after the other, I would start with receiver!
edit : oops you already did... ESC then!

Break out the esc programing instructions and try a throttle recalibration. Most likely its an issue with that.

Thanks for the replies.

John, That makes sense.
I bought the Lehner used and did not get programing
instructions.

A web search brought up this
Motor must be connected ( to hear the beeps)
Turn on TX, switch (or throttlestick) in middle position.
Take off the (red) jumper
Connect controller to receiver, motor battery to controller.
Switch on receiver eventually (if no bec)
Wait about 5 seconds for a beep ( neutral position/ low throttle registered)
Bring stick/switch into full throttle position, double beep after 5 seconds (full throttle position registered).

NOW, for brake and NO reverse, bring back the stick/switch to the MIDDLE position (EXACTLY the same as when you started, that's why a switch is easier, this is the reason why most people have problems) and leave it there until you get another double beep.

disconnect everything and put back the red jumper on the controller.

That should do it.

If you got reverse, that means you put the stick all the way past the middle at the end.
If you leave it @ full, you'll have no brake.....

Anybody have anyway to confirm this?
