What would be a stronger set up, the systems that are air/spring Or i saw a air up air down on robart website. It was for a 8-18 lb, and the kit box has a flying weight for 10-12 so i should be good there. But are there advantages to having an air/spring system?
sure if your air system has a leak thats a contingency, having the spring down feature, but the idea is to install your gear, so it doesn't leak and do periodic pressure tests the hassle of warbirds .
at the start of each flying session you pump your gear up and cycle them until they don't work,I pump my gear up and let whatever plane thats going that day sit for a few min. fully pressurized then cycle the gear if they don't work,or cycle slowly, then they need to be fixed,checked for leaks.
leak checking is easy a little soapy water on the connections bubbles mean leaks simple as that.
it's part of the hobby and with planes with extra equipment like retracts they should work correctly or it doesn't need to be in the air simple as that.
one of the main reasons I am sold on electric retracts none of the air worries, leaks,bad lines,connectors all that goes into them.
