I'm now working with a Belgian gentleman (the one who built that superb all singing, all dancing Orca) to get my shark Mk 2 built. Don't ask me to write his name, I wouldn't have a clue where to start!
This one will be a full hulled version, using two MMB SubSonic bottom hulls, made for me by Mark's daughter Hannah (thanks Hannah!)
I'm using some of this chap's ideas on mine, independently operating front vanes(fins) to allow me to do underwater aquabatics, fixed tail fins to keep the creature level, and a full radio box built into the hull using 4mm thick styrene (courtesy of Andy and Debbie at Models By Design) for the bulkheads and the top flange, and the usual clear lid.
All the required parts on the way, so it's now down to playing the waiting game for them to arrive...still, it gives me time to tidy up my work area.
