Hi everyone.. I bought a Tower Trainer 40 and I am nervous because I had to use throttle reverse on my dx6i so back was lower and forward was higher..

The problem I have is that when you turn off the transmitter and the receiver is still on, the throttle reverses to a wide open position.

Any ideas? is this normal?

I can just picture shutting off transmitter while engine is running and the plane just taking off!!

thanks.

Re-bind the transmitter with the throttle stick in the idle position and that should set it as the fail-safe position.

wow.. that was quick.. thanks much for your help.. I will try it tomorrow and report!!

Do as Chuck said.

Also, NEVER turn off the transmitter before you turn off the receiver. Doing this can cause inadvertant signals to go the receiver and cause issues such as you are experiencing. Always shut down the engine on the plane, turn off the reciever, and then turn of your transmitter.

Transmitter: First thing to turn on and last thing to turn off.

yes, this is great advice for seveal reasons.

Some years ago, a guy at our field brought out a new plane in the spring.

He fired up the motor and checked the controls, upon seeing the ailerons were reversed . He went to change the directions of the ailerons ( with servo reversing ) and got the throttle by mistake.

The plane went to full speed and was headed right for another flyer ( This is a .60 size plane ) , luckly it hit a bump went stright up an stalled the motor.

That was a good ending to a bad situation. I never do anything with a plane , with the motor running , or pluged in for elect. planes

good luck with the plane I have trained a couple people with the tower trainers ( 40 and 60 ) and they are good planes.

I agree, it's still best (safest) to be sure the transmitter is always on while the receiver is on.

The new 2.4GHz radios (like Spektrum/JR) have failsafes built in to keep bad things from happening if the transmitter is switched off or if the receiver loses the signal, but as demonstrated here, you must be sure to set the failsafe settings properly during binding for this safety feature to work.

I know some guys rely on this failsafe feature, and will switch on the receiver before the transmitter, but IMO your better off making sure the TX is on first and off last.

Yea I wasn't too happy to see the Spektrum manuals saying it didn't matter.

What if it is a 2.4ghz

Even if it's 2.4 ghz you still need to stay in the habit of turning the receiver off first. As others have said, a failsafe not set right or other interference could cause problems if the transmitter is turned off first. It's just a good safety habit to have.

Same rule applies. Better to have an EXTRA safety margin and not depend on the failsafes.

I agree with RCKen you always turn the TX on first and it is the last thing you turn off. You will nearly see all of the fliers that has been in the hobby for a long time do this. I do it because back in the early 70's all we had were AM radios. My instructor taught me that and I haven't never forgotten. You talk about a accident waiting to happen, it seemed like when we flew AM.
