Last week I was faced with a new AR636 challenge. I removed a locked-down AR636 receiver with SAFE® from V900, an E-flite speed plane. I wanted to make it fly my new EDF jet, the Freewing Mirage 2000 Tiger Meet. It would be a breeze to reprogram the AR636 today, presumably, with the advent of AS3X® firmware 2.27 made available in April 2018.

I honestly thought it would take me an hour to reprogram the receiver to fly a delta wing, given the new receiver firmware and upgraded programming apps, since I last looked into the AR636. I thought I would fire up the programming app, and change the aircraft type from normal to elevon. I thought I could then set AS3X rate gains, while keeping SAFE panic and self-leveling. Surely Spektrum documentation had caught up in the last three year, right?

No.

You cannot easily take an AR636 that is pre-programmed with SAFE for aircraft wing type X (say dual aileron), and reconfigure it for another wing type Y (say a delta wing with elevons), without losing SAFE in the process.

No one has done this before. Or at least no one had clearly documented how to do this online before. It took me some time to figure out how to do this. Thus this sequel to the 2016 article. Continue reading →
