Using the tanks as active trim would prove challenging. For a start they have no proportional feedback, second the speed of reaction is quite slow....

The piston tanks on these modules were controlled wither with servo actuated microswitches, or Action P44 modules (available from Component shop)....

If you know people that work with Ron, then they would be the best people to contact about setting this unit up.

[Subculture]

Something more to it than that, Ron must be crowding eighty, so perhaps he's looking to hand on the baton to someone who can offer him a deal for the...

A strange choice not to supply your home market, especially when you have little to no other competition. I’m a little out of the loop since handing...

Since when has Ron packed it in?. His website has been offline for a while, but AFAIK he’s still producing products.

[Subculture]

Earlier R&R piston tank WTC. Ron no longer makes them, but he should still be able to give you some tips on how to set it up.

Don't drill holes in your R&R wtc ballast tank, that won't end well. Better to make some saddles that locate each end of the cylinder and overlap...

You don’t need a fly back diode. The solenoid is just an inductive load like the motor.

Usually modellers will place the servo in a watertight compartment and run a shaft through with seals or bellows. In the case of an old Darnell model...

You can purchase waterproof servos, although you pay a premium for them. Hitec do range that’s well regarded, other companies offer them although...

These have a potted stator, intended to be used submerged in fresh water. You don’t state the prop size and voltage, but these will swing a fairly...

You asked this question Mayhem, and got a good answer from Mike Stothers (HMS Invisible). I'd take his advise he's very well qualified to give an informed...

[Subculture]

I don't think so, looks like a lot of the issues are down to lack of skilled staff plus some defects in the original construction which is probably related...

You're going to need some very good batteries to supply 20A with consistency. Does the shroud have some vanes to counter torque roll from the prop, otherwise...

[Subculture]

Some of that TPU is really hard, which is great for structure but I think you want that soft shore 60A stuff for seals....

Loaded and unloaded is referring to the rpm of the motor running uncoupled in the air, loaded is in the water coupled up to the propeller of your choice....

[Subculture]

Alongside measuring current and thrust it’s also worthwhile measuring rpm if you have the capacity to do so. To get the best efficiency from your...

Well I guess from his post he wants this for a boat equipped with gas based ballast system, fitting anything other than low pressure diaphragm style compressor...

Difluoroethane (R-152a) is a gas that tends to be listed as used for airbrush and aerosol propellant. It’s is mildly flammable, but butane and propane...
