Added 9/14 Since I couldn't install it without removing the original brace, I made improvements to avoid interference♪ A friend who uses RDX watched a Kashigari video on YouTube and said, "I wanna Kashigari!" He got into a mysterious mood and asked me to make it (^_^;) (I wish he'd stop that weird mood because it's hard to know how to respond, lol) It seems he's enjoying it quite a bit with the increased roll amount♪ ★Product Description By installing this, you can position the battery higher, which can increase the roll amount^_^ The battery tray is designed to fit the cost-effective Hitec LiPo 3800^_^ Compatible with both horizontal and vertical layouts! Only for vertical layouts, there are multiple holes to adjust the tray position in 10mm increments♪ The material is black carbon-filled resin.
