I think it’s coincidence, that it happens while trying your Mars light.


Maybe the potentiometer is worn out?

In your case I would at first open the Tx,
and check the resistance of the potentiometer with a multimeter, 
if it goes properly from 0 to 10k Ohm.

Juergen,


That's what I'm thinking.

I checked it, still in line, and got 0-6.5K Ohm reading.


I emailed Tony Walsham but he may not have gotten the email as I haven't heard from him on this.

But I have heard from him on other things.


I can fix it if I get a decent part number and find the part online here in the States.

David T if you are watching,

How do I tell if one of my Rx's is a -22 version ?

The mystery one I have has the ident. 61d.

Been some time since I used that model.

** just ignore this David, I am getting old and sillier each day.**SOLVED..... read instructions first.

regards

Bob Comerford

You could simply send David an email.


Normally you can find out by checking in the programming procedure if Selecta is enabled.

If so, it’s an Rx22.


What Tx. do you own?

With a Tx22 you could simply try if Selecta works or not.

FIXED!!!

I must have inadvertently held down the BIND button on the Tx7,
while trying to get the Mars light to work.
 
I read the instructions on how to calibrate the DelTang Txs,
when I noticed they tell you to set the throttle pot/knob to the center position. 

When I was trying to get the Mars light to come on,
I had the throttle knob set to the low off position (no center detent on the Tx7).

Anyway, I centered the throttle pot, turned on the Tx7,
and held the BIND button down until the LED on the board inside went out,
approx 20 seconds. 

Now I have full control of the throttle knob again!!!

Actually, what got me thinking about this,
was I measured the pot resistance on another Tx,
I have, a Tx3 from RCS Australia, they read the same. 

That's when it hit me,
I must have messed up the programming within the Tx. 

Turned out to be an easy fix!

 :doh:
