Big thanks to Mark H. for taking time out to make this video. Here Mark is showing us his DIY arm brace for his Flycam Nano stabilizer. The Flycam Nano is proving to be a very popular small stabilizer, but one thing to note is that even the handle comes in small. If you're not practicing some type of Shaolin Tiger Claw Death Grip (like myself), you might want to look into swapping the handle out with something a bit larger, or better yet work with an arm brace. If you don't know, the handle to the Flycam Nano is hollow and resembles the Glidecam stabilizers. With it's hollow designed handle, it can accept the same arm brace that is used with the Glidecam stabilizers. Of course that original brace (if you're lucky to find one) retails for about $150 dollars.
Mark takes a simple medical use wrist brace found in any local pharmacy and adds a custom DIY bracket to transfer most of the weight away from the wrist, allowing you to fly a bit longer, and possibly a bit steadier. For those with Steadicam Merlin's or Steadicam Jr's this idea will also work for transferring that weight over from your wrist. Mark also makes a good point to talk about how handy an arm brace is to have when you can't travel with a vest. As an owner of a vest myself, I can attest that it's a huge pain to travel with. It's also not very quick to get in an out of and is sometimes a bit dangerous when you're surrounded by fast moving kids. This would be the ideal situation in which you could take advantage of a solid arm brace.
For something like this, you'll probably want to go with the wrist braces that have a 'splint' like Mark's to attach a bracket.
