About Xinhai Dude 辛亥生

The name Xinhai Dude 辛亥生 is a pun in Chinese, as it means both “he who was born in Xinhai” as well as “he who studies Xinhai”. I had an ambitious plan to write something about the great Xinhai Revolution of 1911, thus my blog https://xinhaidude.com. But after an initial flurry of activities the initiative petered out. One day I will still carry it through. But for now, this website has turned into a conglomerate of my work on various topics of interest to me, including travel pictures, RC model airplane flying, inline skating, ice skating, classical music composition, science fiction short stories, evolution and atheism.

Salvage and Reprogram the AR636A Receiver from Eflite Planes with SAFE®

It turns out that most of these planes actually come with an extremely capable $80 Spektrum AR636A Sport receiver, and it can be reprogrammed using just a smartphone and a special programming cable. You can change gyro rate gains, as well as heading gains. You can completely turn off AS3X stabilization in any of the three receiver-side flight modes, if you want to fly your plane without gyro stabilization.

Learn to Skate the Two-foot Grapevine Analytically

Here is my account of how I (almost) learned to skate a two-foot move such as the Grapevine. I am going to describe the learning process in a new language of moment of balance, falling and recovery, unlike how most tutorials explain the move. Perhaps I can provide fresh ideas on learning this move, on two-foot skating and on skating in general, from the perspective of a newbie. I have watched and re-watched countless number of tutorial videos, and have bought and read great books on ice skating written at the turn of the last century. And in analyzing skating and the Grapevine move for this article, I found that I now understand what I was doing wrong, and perhaps can finally learn to Grapevine gracefully.

Ice Skating as a Sequence of Falling and Recovery Steps

This article captures the insight I acquired in this process. Perhaps I can provide fresh ideas on learning to skate, from the perspective of a former outsider. The main thesis of this article is that unlike traditional narratives that describes skating moves in terms of strokes, I think skating can be equally and maybe even better explained as a sequence of falling steps and recovery steps.

(Summary) Flying at Virtual HHAMS Aerodrome in RealFlight and Phoenix RC

Those of you who train using RC flight simulators may have asked yourselves whether it was possible to create, modeled on the HHAMS Aerodrome, an airfield for RealFlight or a flying site for Phoenix RC. I’d been thinking about this … Continue reading

(Summary) Corner of the Lost Planes

There is a “Corner of the Lost Planes” at the HHAMS Aerodrome. This section of the flying field is just a bunch of tall trees, seemingly indistinguishable from other thousand tall trees that surround the aerodrome. But almost every member … Continue reading

Corner of the Lost Planes at the HHAMS Aerodrome

There is a “Corner of the Lost Planes” at the HHAMS Aerodrome. This section of the flying field is just a bunch of tall trees, seemingly indistinguishable from other thousand tall trees that surround the aerodrome. It is probably safe to say that almost every member had lost a plane or two to this particular Corner of the Lost Planes, before they learned, from the sages of the HHAMS, secret incantations that free them from the curse of this corner.

Custom Phoenix RC Flying Sites based on the HHAMS Aerodrome

This is a follow-up to the custom airfields I made for RealFlight. This time I modeled the HHAMS Aerodrome on Long Island for Phoenix RC. One of the flying sites has been accepted by Phoenix RC as an official flying site.

Custom RealFlight Airfields based on the HHAMS Aerodrome

I had been thinking about modeling real RC flight fields in RealFlight for a year or two. It seemed like an impossible task. But it turned out that with modern cameras capable of taking panoramic pictures, plus a simple photo stitching app, this can be done in a few hours. I am using this page going forward, to post updates as I model the HHAMS Aerodrome on Long Island in different seasons under different weather conditions and times of the day.

Watercolor paintings of Chinese zodiac animals in Auryn Ink

In 2013 I discovered an watercolor painting app called Auryn Ink. It’s a great app for the iPad. It allows near-realistic watercolor paintings on a tablet. It has good simulations of interactions between pigment and water. I’ve painted a few simple zodiac animals with it in 2013 and 2014. Here are some of them, plus a few other paintings.
