Welcome to the Spektrum AR636 Receiver AS3X and SAFE PC Programming Series! If there are any questions, please leave a comment below! Thanks for watching!

Hello Dave, just to say I have now had a chance to fly the first plane with an AR636 Rx programmed by me following your series. I installed it on a foam plane called a Crack Yak. This as you probably know has very big flying surfaces. I set up three fight modes, 1. No AS3X, 2. AS3X only (at 20 % gain and 100% priority), and 3 with Safe as well. I also have three dual rates, 30%, 60%, and 100%, with appropriate expo. I have flown it in all three modes. In flight mode 1, I can really only fly it in dual rate 2 as it’s too responsive for me, at my level of experience, with full rates. In flight mode two, dual rate 2, it flies well and noticeably resists buffeting from the wind. But wow! in mode three the plane flies like it’s on rails! I am really delighted! I only installed it on the Crack Yak as a test plane. My real intention is to install it on a Wot4, a plane I started 35 years ago and am now nearing completion. Once again many thanks for your series.

Hello again Dave. As I said a few days ago I think your AR636 programming series is great, and I have now been able to set up two planes with safe. One with a single aileron servo, and one with two. Both seem to be working fine in all respects, although I have yet to fly them as the weather is terrible here in Wales in the UK at the moment. However I have come across an anomaly when setting up the adjustments using my iPhone app in the case of the plane with the two aileron servos. When I come to look at surface set up, (reverse, sub trim and travel), only the rh aileron is shown available for adjustment. So the only way I can trim the ailerons both to centre is to trim them both together with the trim slider on then tx, until the left one is cantered, leaving the right one off, and then sub trim the right one back with the app. Does this sound ok or am I missing something? Best wishes, James.

James Tennant-Eyles first, thank you for the compliment, I really appreciate it and so glad you’ve been able to get some AR636 receivers working well for your planes! I honestly haven’t tried doing what you’re doing with two aileron servos but what you’ve described seems like a viable work around. Let me know how it works out!

[@jamestennant-eyles9870]

Hello again Dave, thanks so much for your speedy response. Well the workaround seems to be successful as everything is working properly, I just need some good weather to test at the field. I noticed another odd thing (to me) when setting up the AR636 with safe on the twin servo plane. When I first built the plane I installed a standard 6 channel Spektrum rx, I carefully centred the surfaces mechanically with the rx installed, and very little sub trim was required. However when I later installed the 636 on the same plane all the surfaces were substantially off centre at centre stick, requiring a good deal of sub trim to centre them. (This wasn’t the case when I set up another 636 on the other plane with one aileron servo). I could reset the servo arms on the servos rather than use sub trim, but this begs the question why do the same servos have different centre positions for different rxs. Is it your experience that different rxs installed in the same plane, with same mechanical set up, will set the servos at different positions on centre stick? Once again thanks for your series. As informative as the Flightengnr pdf is, I would have found it much more difficult to do the setups, without your logical and clear sequential videos. Best wishes, James.

Good Morning, To use this Program is it necessary to UNPLUG the Servos Connections? Thank You.

Hi Dave I put the 636B in a FlightLine FW190 with the P51 safe select set up everything works fine but the elevator is in reverse only in safe any suggestions? Thank you

[@TheRCAirMarshall]

Christopher Quiles when you’re working with a model file that wasn’t intended for the exact airplane, it’s important to remember some of the critical points of AR636 programming. First, your three critical control axis can not be reversed in the transmitter. So aileron, elevator, and rudder can not be reversed in the transmitter. Second, your receiver orientation must be correct. The AR636 has the orientation set up in the programming, whether that is with the pins facing forward, facing backwards, receiver upside down or right side up, it must be configured correctly in the receiver. If going into SAFE mode causes your elevator to go in reverse, it sounds like a receiver orientation problem. So take a look at the two things I mentioned above, all servos are normal in the receiver, and that the receiver orientation is correct. Should work fine once you get those two points worked out.

Can I increase travel in the Receiver only to get the desired control throws? I keep Transmitter travel to 100%. Will this affect SAFE/AS3X? Thank you for the great serries.

[@TheRCAirMarshall]

SRC yes, in fact this is exactly how you want to do it. AS3X and SAFE go by what’s programmed in the receiver, not the transmitter.

[@src2920]

@@TheRCAirMarshall Thank you for the quick reply. If I may ask..I actually maidened my first edf freewing 70mm hawk with absolute rate gain/ Priority settings of eflite viper. On SAFE ON mode it flies solid. I did not try AS3X only. Is it logical to hope that SAFE On will still work after I have increased the travel in the receiver keeping everything else same as before?

[@TheRCAirMarshall]

It should work fine, yes. If after the travel adjustments you get a bit of oscillation just dial the gains down a bit. The receiver will have a bit more throw to play with so AS3X and SAFE may have better response now.

@@TheRCAirMarshall Thank you Sir😊 Feeling already confident before my second flight. Once again this serries was very helpful to understand the SAFE functioning. Thank you👍🏽

[@TheRCAirMarshall]

Glad it helped! My pleasure 👍
