Charging Airtronics TX

I believe it is the same size as the universal plugs other than it has the tab on the side that has to be removed. The battery with the futaba connector will fit the on-off switch (when the tab is removed) that came with the tx. I have it bound and the only thing that is really different is that channel 1 is elevator and not aileron. Have to remember that.

As stated in my post above, the Radio Shack part no. 274-1567 fits the Airtronics transmitter. Also as stated above, it is 5mm OD and 2.1mm ID. I do not know where the included quote picked up the dimensions quoted here but it was not what was stated above. Incidently, if you have a Hitec transmitter charger, it will fit and function perfectly with the RDS8000 transmitter. If you replace the connector on the Futaba charger with the 274-1567 connector it will also work .

CORRECTION!!!!! You can NOT charge an Airtronics transmitter with the same charger or harness as you do all others. JR with its opposite polarity is of course completely out of the loop.. The difference is not electronic, but mechanical..........
The charge connector most used has an internal pin of 2.5mm - NOT 3.5 as stated. Airtronics uses a smaller one with a 2.1 pin. The larger one will go in, but will not make a dependable solid contact.

Ken in your review of the RDS8000 you say that you put the RX in foam. Is it different than the DX-7 where they say not to do that because of the heat buildup. I know one of our club members has JR and he said not to put the rx in foam.

I've always wrapped my receivers in foam. The Airtronics radios don't have heat issues like Futaba does, and maybe JR/Spektrum. IMHO you're better off wrapping it in foam if you have "wet" power in the plane. The vibrations can do a lot to a circuit board. You could probably just put foam underneath the receiver and then secure it in place. I just prefer to wrap it in foam.

I would too. If you are not having any problems then I am going to wrap in foam. For my less than perfect landings (should I ever have one 

) Who am I kidding, my next perfect landing will be my first. I like to excite the crowd with my bouncey, bouncey, OH s***.

What I do is use some heavy-duty velcro on the bottom. In my little pea-brain, I think of it as isolation from the airframe. I also wrap a length of velcro tape (availabe at your favorite Lowes).
I usually make a mount of 1/8 ply that is "shock mounted" to the fuselage then put the receiver on that with the velcro mount. Works pretty good and, to my pea brain, isolates it (as I said.. jeech. I must be tired). The AR7000 receiver (DX7) is light enough that it does not require a lot of foam padding, and I feel that the method I use seems to work well. I've never had a problem.

Trying to program my RDS8000 to get throttle-cut. It seems no matter what I do I cannot get to the screen that says T-CUT. Following the program instructions on pg. 36 of the manual says "To get to the th channel, then press down several times on the function key until you get to T-CUT". 1st press gives me REV-2nd gives me CNT and 3rd gives me EPA. Nothing after that. Am I doing something wrong?

Goirish,
It's hard to tell you what value to use because it's going to be specific for your application. Basically, put enough in it so that the barrel of the carb closes completely when you press the throttle cut button. Keep adjusting the amount until you have enough to close the carb.

I kept looking for the ETC on the big screen. My poor bionic eyes could not hardly see the etc after channel 8. But thanks you you all, we got it.

Gene, what I did with my RD8000 (same basic radio function) was set up the throttle as you would any other. On the low end, set the trim so you are about mid point with room on both the up and down trim. Just remember that this is the center point. This way, you can do what you wish and, once you get the engine running and the idle set ( mid trim), then you can set the throttle cut button and the amount of throw you want to assign to cut the throttle.
The mid trim allows you some slack for adjusting the trim and also allows you to use the throttle cut button to cut the throttle. It comes down to setting up the thing according to your flying style, setting up your idle point and RPM, then flying.

I have been reading, tinkering, trying,programing, cussing and just plain fooling with the tx. Trying to learn about it before I take it to the field. Nothing worse than getting to the field and saying "Anybody know how to work this blankey, blankey thing" Of course you will have a very nice looking plane and you want to impress the crowd and then don't know how to turn the thing on. It is different than my Futaba's. Slot 1 elev-slot 2 aileronjust the opposite of Futaba. I think I have the D/R fixed, T-Cut. Stop-watch set, now where do I turn it on again.

I have my RDS 8000 set for the countdown timer. I fly 11 minute flights for the most part. The timer will beep and let me know it's time to land. Doing it this way you don't have look down at the radio to see how much time you have left like you would if you using the stopwatch timer.
