Can I use the PA2 in conjunction with fail-safe on my PCM transmitter to help protect my airplane in the event of interference?
Absolutely! This is an excellent safety idea. The fail-safe feature, if set to continue the last command, will often keep your model in the loop or straight flight it was last doing, but unfortunately, sometimes it will keep your model in a precarious situation you didn’t want it locked into. By using the PA2 in combination with preset positions on the fail-safe settings, you can help ensure your model will go to level flight at slow but safe airspeeds and hopefully safely ride out the interference. To set up the fail-safe for this combination, we recommend the following: First, please remember that you must be using a PCM RX and be in PCM programming.

Second, fly the aircraft and turn the gain up on the PA2 until you find the maximum setting it can be at before the plane starts to ‘hunt’ or ‘waggle’ because the gain is set to high. Have your spotter notice where the dial is set at that time. Now, land the aircraft and set up the progra
