Realistic...yea sort of. Even with the adjustable pot it seem's too much to me. I've operated tanks using the turnigy chip and the tamiya KV/IS DMD have it programmed in of which I have a couple. For a casual spin around the backyard it's ok, then the novelty wore off and I wanted the original responsiveness back. Really don't like it for IR battling especially around buildings or trees as in the heat of battle your pretty much guaranteed to hit something with your barrel/tank. Their not expensive or hard to hook up so no real loss and you may enjoy it, just not my thing.
