Review on 💨 Pneumatic Solenoid 4V210 08: Efficient Pilot Operated Connection for Enhanced Performance by Jesse Azuse

I have already ordered several, none have failed, all of them match my props perfectly. It's noisy when venting, but that was remedied by wrapping the exhaust with a sock. For example, if you want to control a pop-up screw that recedes to move more slowly, insert a tube with a valve in the exhaust port. I have a small brass valve on the HFT and it works well with my screw coming out quickly. but the back is slow. They really fail, I have another on the cage prop with a blinker that actually powers it to open and close at blinker speed and has never failed in 2 years of the Halloween season.
