TEXAS eMAX Electronic Timer
You have seen the rest, now FLY the BEST
Read what Don DeLoach, Editor of the NFFS Free Flight Digest,
has to say about this timer:
"The Texas Timers eMAX is a game-changing timer for Electric FF. It is ultra-light and slim, run and DT times are easily adjusted in the field, and it accepts the popular Bauer remote DT as an option. eMAX is certainly the best, most feature-laden timer currently on the market for AMA E-36, A and B Electric, and the new Electric NOS."

The eMAX timer was developed and designed in conjunction with Dick Ivers, a well known and successful electric flier. Dick has always designed his own timers, and we are fortunate that he agreed to team up with Texas Timers to produce this outstanding product. This is the new benchmark in timers for electric Free Flight.
This timer uses two high quality rotary switches to select the desired motor run time and DT time. The switches have a nice "bump" so you actually feel the setting. The ten different motor run times and 8 different DT timers can be intermixed in any combination to provide 80 unique flight profiles. And, if this is not enough for you, an optional Data Port can be used to set either to any desired value from 0 to 600 seconds in tenths of a second increments. The only restriction is DT time may not be less than the motor time (for obvious reasons) and the timer actually prevents you from doing this. Use of the Data Port requires a PC (using free downloaded software) and a special cable from us. I bought a few ASUS refurbished 7 inch netbooks that work great and am offering them to my customers. Comes with a protective case, and charger. You can keep up with your email and read Kindle books in bed when not using it to program your eMAX. To see what a typical screen looks like when using the Data Port, click HERE. No Apple products are compatible.
Why 600 seconds? We felt that some sport fliers might enjoy extended times with some planes where flying conditions permit it. And we could without sacrificing any required or otherwise useful DT times.
All needed motor and DT times to fly E-36, AMA Electric A/B, and all settings needed for the new Electric Nostalgia event in both Cat II and III are included. We also provide short times for trimming and testing as well as short field flying. Nothing has been left out to make all your flying enjoyable. You can see a table of all pre-programmed times by going to the PDF instructions included below. A high quality decal is available to place on the wing, pylon, or fuselage, so you have immediate access to all the information needed. No more guessing if you got the correct number of button pushes or light blinks. We had YOU the user in mind all the time during development.
Should you desire to use RDT, we can provide an optional 6 inch pigtail with a connector that can be plugged directly into the Airtek or Sidus RDT models made for use with a timer. If requested, we can instead install a thee pin connector on the eMAX timer. See both Here
The eMAX incorporates a brilliant yellow LED used to show timer status, and in no way is it used to set any times. A slow flash of the LED indicates that power is on. This is an "idle status" indicator. It is very useful for helping avoid leaving the battery connected and possibly ruining the LiPo battery. A rapid flash is used to alert that the timer is "armed" or ready for flight. For ground testing the motor time without running down the battery the motor can be unplugged and the LED is on when the motor is running. It also is on at the times the servo is being moved. Both of these features allow you to test and demo to the official that your times are what they should be. We automatically deduct 0.3 seconds from the true run time from that shown on the setting to allow for the "human delay" in working a watch.
The push button on the front serves to arm the timer and start the motor and timer and it has nothing to do with selecting or setting the times. From the slow flash "idle" a single tap of the button "arms" the timer and the LED begins an easily seen rapid flash. After this, the button must be held in for at least 2 seconds (a safety feature) and then the motor starts running at full speed. You release the button at launch and the timer beings running. Should you change your mind about launching, a single tap of the button with the motor running returns the timer to the "idle" state. No time settings are lost or changed. If you want to change either time setting, this can be done at any time until the motor has started.
The timer has a standard Auto Rudder or Auto Stab function that happens at the time the motor is stopped. The servo rotates 45 degrees CW to release any such function, and then returns to the "home" or 0 position. The AR function is now a no cost option. Some customers prefer to not have it. Remember, AR is only allowed in AMA Electric B and F1Q. At the time of DT, the servo rotates 45 degrees CCW to release the DT line and then returns to home. After you have retrieved the plane, it is ready to go again, all prior settings are retained. Or you can instantly make any changes you wish. To see what the servo positions look like, click HERE. While talking about the servo, we also offer two different really nice wire hinges to use on your DT release or for AR and other auto surfaces. See both of them HERE
Removal of the battery does not cause loss or alteration of any time settings, including those made through the Data Port.

See a nice neat installation HEREThe instructions for a PC HERE, and the Quick Start Guide HERE. You can download the PC cable driver used with the Data Port for free HERE
The installation kit now includes a nice laser cut cut cover for the timer. So the full kit has the mounting plate, front cover, great decal, and a super hinge for the DT wire. You can see all these items HERE.
USING THE DATA PORT?
I prefer using a PC based computer. Since laptops are a bit big to carry to the field, I find the older netbooks to be perfect. In fact, I use a netbook for all the programming of my timers, as well making changes to the functional settings. Netbooks are no longer made, having been replaced with tablets, the only way to obtain one is used from eBay. I was able to find a few netbooks as refurbished with Win XP or 7 in them. These are perfect for use in the field and you can do email from your hotel. The battery may not be like new, but that is fine as you only use the devise for a few minutes to change your time or servo settings. All of them are relatively clean with nothing more than minor blemishes. You can bid on one with eBay, or buy one of my refurbs. nt
WHAT WIRE GOES WHERE?
I get a lot of calls on how to connect wires to the timer. I hope this bit of explanation will help. There are only two main connections to an eMAX timer, regardless of the pin type configuration. If you look carefully on the circuit board in the area where the ESC and SERVO connector pins are soldered to the board you will see a small (-) and small (+) symbol. The (-) is for the negative or black wires. So, when plugging in the ESC and SERVO connectors, match the black wire with the (-) mark on the board. For pin terminations that are at right angles to the board, the SERVO connector goes on the bottom and the ESC on the top. In addition, the ESC and SERVO connectors have the metal pins inside the plastic housing showing on one side and invisible on the other. The connectors plug in with the side NOT showing the metal pins up or not showing. The black wire will be on the correct side. The red wire is always in the center or (+) pin.
For the ESC the other wires are not so confusing. You have three wires of the same color with the same connector on the ends. The motor also has thee wires of the same color, but likely different) and the same connectors. What wire goes where? There is no way to know. You must connect the three wires any way and see if the motor is spinning in the desired direction. If it is not, you only reverse any two wires, and the rotation direction is now changed. There should be no confusion on connecting the battery wires to the battery. Only remember that you must disconnect the battery to ESC wires when not using it as there is a small but steady power drain that will ruin your LiPo battery if left connected for an extended time.

* The MF model has four servo timed functions and comes with an Energy Limiter Port which is now required for the F1Q Event. A Data Cable is required to use the timed servo functions but is not required for using the EL. The H pin configuration is the only way the MF is supplied, now. This is the top timer for use in F1Q. Physical size and mounting is the same as all other eMAX series timers. Call for any questions. 423 282 6423
