I've searched for hours trying to find the good article on using the Programer. Can someone point me in the right direction?

PS I am having trouble centering the sevos to my transmitter , Futaba.

This should help.

How are you centering the servos? Or what is the procedure you've attempted thus far?

Your goal is to match the servos to the drive pulse your TX transmits with trims and mixes zeroed out. Most TX's do NOT transmit the industry defacto standard of 1500us pulse width (us=micro-seconds). So setting the servos to 1500us is pretty much worthless in this scenario...

If you have specific questions or needs share them here and I will help you work through them.

Thats right the 1500 is worthless. When all the mixs and subtrims are at zero in the transmitter , how do I read the pulse from my reciever which will be the actual servo center of my transmitter?

Thanks Kent

You can use the Hitec Programmer to measure the pulse-width at any position. While this information is interesting it not directly usable to correlate the required servo programming parameters.

Best case is to use the TX and the programmer hand in hand in what I refer to as ITERATION methodology.

Zero the TX trims and sub-trims. Connect the servo to the TX and RX channel in play for the specific servo. Note where it centers NOW and what direction is needed to move the arm to center the servo or make it perpendicular to the servo case. Connect the servo to the programmer, select program “epaneu” , roll the knob to 1500us make sure the servo arm is as close to perpendicular as possible now! Move the servo 3us in either direction (write down whatever you end up at (1503) hit the center save button and now arbitrarily set the end-points anywhere in both directions. Reconnect to the RX and note how close you are now as compared to previously. From here you can ascertain if you moved the servo in the right direction or not and if you need to move the arm more or less to center the servo using the recorded pulse drive numbers add or subtract as required. From here reconnect to the programmer and start over, it’s a hit and miss numbers game from here, takes a few minutes to get used to the process but once you’ve worked through it a few times it goes real fast. End-points are set up the same way. Make sure the EPA/ATV or travel volume percentages are equal in either direction first.

Hit or miss is what I have been doing but cant get a hit. OK thanks I'll keep at it untill I get it right.

I have a method that seems to work for me. With the servo, RX, TX and programmer all on a bench in front of me I find the center first. I use a small 3" machinest square to get a good 90 degree angle.

I use a Futaba RX and TX and typically on each servo end up in the -8 to -10 range to geta center reading. I set the end points to my control surfaces travel limits.

DO NOT SET SURFACE TRAVEL LIMITS WHILE ATTACHED!. you can overdrive your surfaces and break them.....this is bad.

I will admit whan I was first trying to figure this programmer out I used the video on DOD and it was a HUGE help!

I would like hitech to make getting the center position a bit easier. THere ought to be a way to read what the TX is saying center is and setting it direct to the servo without all the hunt and peck method.
