Got this build to come in under 18 grams dry. Used an E010 frame and removed the battery bay, then used the little pins on the side of the frame to attach a small rubber band to hold the battery on. I also replaced the stock vTX antenna with a small piece of wire similar to the way the vTX antenna is on the Crux3 FC. I'm sure range has been affected, but I built this strictly for flying around my basement Whoop course, and my living room, dining room, and kitchen so it's never far enough away from me to be an issue.
