What on earth is SAFE® or: How I hacked AR636 from V900 to fly the Freewing Mirage 2000, with SAFE and AS3X

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

2018 XiSheng RC Extravaganza 西盛遙控飛行嘉年華

New Taipei RC Flying Extravaganza (西盛遙控飛行嘉年華會慶) organized by NTAMA (新北市航空模型協會) took place on Sunday, Nov 4th, 2018. It was joined by flying enthusiasts from all over Taiwan. I went with friends from the RC club from Kaohsiung 高雄市遙控運動協會, courtesy of 陳振國.

This article hosts pictures I took and edited of this event. Perhaps I’ll come back and finish it with additional descriptions. Perhaps I won’t. It exists for now as a place for enthusiasts to browse and download pictures I took of them, or their planes. I compiled two YouTube videos: a shorter one comprising video clips I took that day, as well as a longer slideshow highlighting some of the many exciting moments I captured in still pictures. As usual, some of the best pictures will eventually end up on Wikimedia. Continue reading
