Q. My SAFE airplane does not seem to bind.
A. All AR636 SAFE equipped receivers, be it a SAFE, SAFE Plus or SAFE Select must be oriented on their landing gear (as if about to takeoff) and completely motionless for the system to calibrate and bind. The indicator lights in the receiver will stay off until the plane is put into the correct orientation.
IF it is a AR637TA/AR630/AR631 equipped model, it simply needs to be motionless for 5-10 seconds to initialize, no need to be in the correct orientation or on the landing gear.
Q. My airplane does not have much control throw and has nearly no down elevator.
A. This is due to an error in radio setup. Essentially the model is in Panic mode, which is controlled by channel 6 (Aux 1). Make sure you have this setup properly according to the manual. Most of the time it is because reversing Aux 1 was neglected.
Q. When I do a control correction test, I am not seeing any movement on the surfaces.
A. This could be one of two things. First, if this is an AS3X only plane or SAFE is not turned on, then the corrective movement on the controls can be subtle and is only proportionate to the disturbance that the model endures. Move the model quickly and watch the surface as the model is moving. Secondly, correction does not start until the throttle has passed 25% at least once. After that point, throttle can be brought back to the off position and the control correction test can be conducted. Try Beginner mode, which has self-leveling, where correction direction is most obvious.
Q. I am having trouble with the AS3X App; it keeps crashing on start up.
A. Make sure you have granted the App the permissions that it requires from your device. This can be found in the App settings menu of your device. It is important that the volume of your headphones be at the full position. It is also important to delete all previous versions of the software, the AS3X named folders and AS3X App cache in your smart device.
Q. Do I have to choose an unused transmitter switch in order to activate SAFE Select?
A. Any switch can be assigned the SAFE Select on/off feature, even if it’s already used for another channel or feature such as flaps, retracts, expo or dual rate. However, transmitters above 6-channels may require activation of the switch in the system menu.
Q. Where do I start the gain levels?
A. The rule of thumb is to start with relatively low gain values. You can use the flight mode option to experiment with different levels on the fly. Another option is to find a BNF® airplane with AS3X technology that’s relatively similar. All registered receivers can accept AS3X presets available from the Spektrum.com website. Upload the preset and then use the flight mode option to fine-tune to your liking.
Q. Why would I want to use the flight mode option?
A. The flight mode option allows you to assign gain values and set gain levels for different flight conditions (pattern vs. 3D flight) or turn AS3X off completely from a switch on your transmitter.
