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

How to master short-field landings with EDF jets such as the Avanti S
![]()
There is a real lack of information online about making successful short-field landings with EDF jets such as the Avanti S. I don’t know whether I should attribute this to search engines being saturated with merchant pages, or blame Facebook for hiding useful content from search engines. Looking for videos on YouTube for the same yields basically nothing. Last time I failed to find useful info, I wrote Learn to Skate the Two-foot Grapevine Analytically, despite being relatively new at ice skating. This time I’ll do the same without reservations on EDF jets and short-field landings, based on my personal experiences.

Droning at and around Ogunquit Beach

This article is a part of the Ogunquit in September Guide I am writing, for the model aeronautically-inclined. It is the main and the last installment in the series. Together with the modern beach equipment installment, it details everything you will ever need, before you head out to fly a drone or two in this beautiful beach town. Continue reading

Modern beach equipment for the model aeronautically-inclined

This article is a part of the Ogunquit in September Guide I am writing, for the model aeronautically-inclined. Obviously, those who enjoy flying radio-controlled planes at a beach will find this article useful. But I am also certain that any modern man or woman planning a trip to the beach will not want to miss this one.
I know it, because I’ve spent countless nights before the trip googling for the best beach equipment to bring, to no avail. If you are looking for novel contraptions that solve known problems with ancient beach equipment technology, you will not be happy with what you find online today. Even Google isn’t smart enough to weed out hastily-assembled, so called “top ten beach equipment” websites that simply scout Amazon for highest-ranking sales. YouTube is full of computer-generated videos with screenshots stole from above-mentioned “top ten beach equipment” websites. And most search engines nowadays only want to show you online shops, because… that’s how they make money. This leaves old fashioned research work as the only option. I read and combed through tons of user reviews, and wrote notes. The trip proved that I did find the right beach equipment to buy.

Ogunquit in September – for the model aeronautically-inclined

This is a guide to upcoming articles I will be publishing, on Ogunquit, a small town at the southern tip of Maine. The guide serves as a preview to these articles, before they are written and published, showing this beautiful river, the town and the beach named after it, in September. This was when kids had to leave the beach, to go back to school, and just before the autumn arrived in full force. Some articles will explore the Marginal Way, Perkins Cove, Cape Neddick, York, Wells, Kennebunkport and plenty of public beaches in the area. Some will focus on hotels we’ve stayed at – the Tidal Suites at the Norsemen and the Cliff House at Bald Head Cliff.
I’ve also brought the current obsession of my life together with travel and videography. Most of these articles will be of interest to those who are model aeronautically-inclined. While I did not have room to bring big model airplanes, I did pack two micro airplanes and a variety of kites. While flying a sailplane on the peaceful and expansive Ogunquit Beach proved to be a relaxing pastime, fighting the precarious Bald Head Cliff in inclement weather against a stormy sea turned out to be quite challenging.
Did I mention that I adopted a pet seagull during this trip?
Pictures I’ve taken on a meager iPhone will be culled in time, and the remaining usable and useful ones uploaded to Wikipedia for illustrations on various relevant articles, continuing my series of Wiki Vacations (from here and there). Continue reading

A Resurrected Ornithopter – the Flytech Dragonfly

The Flytech Dragonfly was one of the most innovative flying toys when it came out in 2007. It was the first radio-controlled ornithopter mass-produced for the general public. Sadly it is no longer available for purchase. To add insult to injury, there has been nothing in the market for ten years that delivers remotely the same level of giddy fun for the money. Some event reminded me of the Dragonfly recently, so I went through boxes in my basement to find the two units I bought in 2007.
Unfortunately their tiny lipo batteries have since gone bust. With help from ancient posts on rcgroups.com, I managed to resurrect one of my dragonflies with a new setup. It allows me to reuse abandoned lipos from my Blade Nano QX which I have aplenty. Suddenly I no longer need to wait for 20 minutes between flying sessions, for the built-in battery to be charged. I can now fly it effectively non-stop. Continue reading

Ode to FlightLineRC 1300mm Focke-Wulf Ta 152 H-1

This is not a real “ode”. And I don’t know how to write one. Nevertheless I find myself compelled to publicize the greatness of this model warbird, after flying it time after time in the last month. I am talking about the FlightLineRC 1300mm Focke-Wulf Ta 152 H-1.
Unlike a few occasions in the past where I felt the need to praise some planes (e.g. Extreme Flight Laser) but sat on the idea, this time I actually decide to comment on rcgroups.com. It was then only natural that I turned that into a quick article here.
If I must use one sentence to describe this 3S-capable plane, I would say that, when run on a 4-cell 2,600mAh lipo, it transforms into a graceful speed demon in the sky. Continue reading

Hot Air Balloons in Search of a Landing Site
Flipping through pictures on my iPhone, I found a few interesting ones taken in August 2015. They were from an unexpected encounter with hot air balloons while I was visiting Lancaster, Pennsylvania. It turned out that they were from a balloon ride tour agency with a misleadingly official name, The United States Hot Air Balloon Team. Nonetheless, I found the ground crew to be professional, and the pilot to be knowledgeable and helpful. I uploaded some of these pictures to Wikimedia, as I often do with useful pictures taken in my free time. Continue reading
