I just noticed that Mike Shubar (of Mike's Subworks fame) has posted several sets of instructions on his website. Mike and his effervescent wife Alyssa have been vendors of RC submarine supplies, hull kits, etc., for quite some time. They recently took over as US distributor of the SubTech line of products as well.
On his website, Mike shows with easy to follow photographic instructions, how to utilize his motor mount assy, how to assmble a bllast tank vent valve solenoid, and how to make a gas (Propel) ballast system.
Very cool Mike!
