Converting gas system to.....

[subkraft]

.....rcabs or snort and blower arrangement. Read on another board that shall remain nameless that this has been done. I've got a couple of propel systems tubes lying around, can't get gas for them, considered trying butane...can anyone advise on the conversion?

Thanks

Isn't propel largely made up of butane?

You could get some blower pumps and plumb them in to your tanks to blow your tank like the snort system. Inexpensive and dead simple.

Mine started out it's life as a propel system, now it's RCABS. the only thing I kept from the original setup was the motor housing.

RCABS great but it's not a "one size fits all" approach. Due to the limited amount of air within the WTC it hard to achieve a high freeboard. Great for nukes not WWII boats.

Easy to fix for large(er) boats....add one or more air flasks.

Re: Converting gas system to.....

The majority of ballast systems I encounter recirculate the air. Piston tank systems, water pump systems with sealed tanks, including the OTW system which compresses the air into the fore and aft compartments. They all work on boats with low and high waterlines.

However they require fairly large cylinders, as the systems run at modest pressures, and the displaced air has to go somewhere.

For boats with very high freeboard, a dual stage system has a lot going for it. Either a snort type, or vented water pump, main tank, with a smaller trim tank based either on a small piston tank or a sealed tank water pump system. With those you get the advantages of each system, and it follows fullsize practice more closely.
