I recently built a Sig Wonder and have flown it several times and believe it will be a keeper. However, I was always needing three hands to hold, start, fiddle with transmitter, lift it from the table, etc. I usually asked someone else to help me start the plane for safety reasons. But wishing to start it on my own safely, I built the below pictured holder. I can clamp it to one of the tables that are at each of our setup positions under the covered shed at my flying field.
