Default How to make retracts extend from low pressure

I'm new to pneumatic retracts (pun intended). I really like the idea of Robart's #176 Robart Retract Pressure Guard as a safety guard to make sure retracts are down when you turn a radio on, but more importantly to lower and lock gear if you get below a certain pressure.


They're sold out and being re-engineered. I haven't found reviews for them. I've looked for possible other brands but haven't found any. Maybe my keywords aren't right. Can anyone help with guidance on reviews and/or if there are other options out there?

I'm also new to Spektrum. Maybe there's a telemetry gauge we can have trigger a warning when pressure gets too low? If not, maybe there's a way to contact Spektrum with the idea? If a warning could be created, it seems an action could be taken to lower the gear.

Powerbox has a telemetry pressure sensor for their radios that can then kick a channel based on a preset value.

Tam Jets used to have a lower pressure device but they are out of business, Robart is probably something similar, those are the only ones I know of.

In the meantime, pressurize your system in the up and down positions and see if it holds pressure, if you have a leak you can find it by using a few drops of dish soap in some water and applying it at joints and such, it will bubble if its leaking.
