Dion,
I have not seen any at the races I have attended. There is a great 1/4 Scale Gas Tunnel group on Facebook that has these hulls posted, so I joined their group. Check it out and add to the conversations.
I sold my gas tunnel after it won the Fall Nats a few weeks ago, and I am waiting on Carl to upsize his THOR for my new gas tunnel project. My old gas tunnel was consistently 58-61mph, and with my pad extensions and transom changes could easily make full speed turns. I am going in totally different directions on some aspects and I am hoping to push speeds to the mid 60's consistently.
What "Stalker" speeds are those hulls getting and can they make full speed turns?
