First one had CJM Gear, still have them for sale on RCU, the second used robart gear. The gear on mustangs is a very weak point. once you are done building the wing reinforce the ribs and mounts with fiberglass cloth. The gear on the Pica are long so they transmit a ton of force to the mounts if you are a little sideways. I would also recommend making your tailwheel trail, rather than the scale setup.
