You are looking at a re release Kyosho optima that has been upgraded for optimal performance. I added a wing to the back and changed the body to a detonator style. I did that to fit an esc and receiver easier. The tires are way better than stock and made the buggy perform way better and way more responsive. I had a 3300 kv brushless setup on it so removed the rear plate. You may want to leave it off or put it back on depending on your motor setup. Everything works great and the gearbox is fine. I’m including a belt drive setup and pinion gear as well. The steering servo is futaba and is practically new. There’s also a full javelin body set with wheels that are basically new I’m throwing in. I’m no longer in rc so time to sell.
