I did convert mine over to R/C. It is a very easy boat to convert. I made a different prop for it and replaced a couple of the appendages that I thought might be easily damaged. The boat handles very nicely, although it is a bit sluggish in turns.
I am using a very simple gas cylinder in it now. I started off with a pump version, but the pump had leaks in the housing so I am searching for a new make of pump to replace it with. Currently, the XXIII is sitting on the shelf,unpainted, while I get a few version of our new cylinder prepared to go out to a few friends as test platforms and getting my Permit, Sturgeon, and Kairyu ready for the SubRegatta in Keystone, Colorado in July.
