Here's an inexpensive little tripod (on sale right now for under $6) that you can use to set your single hand grip gimbal stabilizer down without powering it off. Keep in mind this particular tripod is pretty small, so it's best for those GoPro to Smartphone sized Gimbals. We're talking about Gimbal Stabilizers such as the Zhiyun Smooth-Q, FeiyuTech G5, or the FY-WGS Wearable Gimbal. And obviously it will also work as a small pistol grip placed directly under your camera body when you're just casually shooting hand-held.
DJI today has made available their latest Gimbal Product - OSMO. The Osmo is a handheld system that allows you to use the DJI Zenmuse X3, X5 (Pro), or X5R (RAW) Camera + Gimbals.
Keep in mind that the OSMO is dedicated for use with one of DJI's cameras. While I think anyone with a DJI Inspire1 + X3 camera might be tempted to grab an OSMO, many still believe the quality of the GoPro HERO4 is still better (HERO4 certainly better in low light). You can already get a very stable GoPro HERO4 gimbal for less money, so I don't think I would personally use this for my X3.
But if you're looking at using an X5 or X5R DJI Camera system with your Inspire1, then I can see how this will add great value by allowing you to use it both on and off the Quadcopter. The DJI OSMO is already available to order on the DJI website (here).
