Hi guys..
Need some help..
I just bought an Airtronics m12 transmitter..
Previously using the m11..
Initially I tought I can bring over the 3s lipo which I was using for m11.
But when I plugged in to the m12, it sounded an alarm and showing over voltage on the screen. I immidiately switched it off and plugged off the battery.
I just realised that it only needs 2s lipos. .
I then take the normal alkali AA batteries to switch in on and it works ok. But ive not bind the receiver yet.

My question is will it damage the transmitter?

Thanks for viewing in advance.
Do advise.

Check the manual, you might be able to reprogram the settings for use with a 3s battery. Otherwise dont use it.

well, if it still works after you put in the normal batteries, I would assumed it working fine otherwise you cant even power on. I might be wrong too

The regulator circuitry in the TX will protect your TX during that brief moment of of high voltage connection.

Not to worry, chances are that everything is ok. Just watch out for the tell tale signs of damages such as lateancy issues, glitches and software crashes.

If you read in the manual that 2s Is the max then its possable that you have damaged it. I don't have an M12 but I have a brand new MT4 and it states In the manual do not use any thing larger than 2S lipos!!!! I would suppose but not sure that the M12 operates on the same Voltage levels as the MT4 which is 4.0 to 9.6 volts. If you got the transmitter to come on with the 4 AA alkaline batteries then try to bind your receiver to it and hook up two servos to the receiver and see if the servos move with inputs from your transmitter. If that works then I would say That your radio is all right but if not then you will have to send it to Airtronics to get it fixed and they may not cover that because you hooked up the wrong battery. So Give it try!!! Michael Johnston

M11 an older were 11.1V
M11X AND NEWER ARE 7.4v

My advice is to run through all of the settings, epa adjustments, and see if everything works first. Then bind it, if it binds, then run through the settings again and make sure that they are adjusting the servos and such.

Being that it turned on, I believe you are fine, and I believe the warning light is to inform you that the voltage is to high. I would presume that had you completely disreguarded that light and just used it, over time you would mess it up.

BOL.

The m12 takes a 2s lipo max. You can adjust voltage warnings buzzing, vibrating, etc... but the manual says no to anything above 2s. To answer your question, if it still works, it appears that plugging in a 3s lipo doesn't break it? Sounds like it has a mechanism to avoid frying the circuits.

Consider yourself lucky and count your blessings.
