Okay guys, for years both these companies have been industry leaders in their products. BVM makes top notch accessories and Ultra Precision makes the best mechanical valves in the market. The UP2, UP3, UP4, UP6, are as common in jets as it gets.

Now there is a bulletin out by Ultra Precision that says that BVM THIN O-Ring lube (is clear, comes in a vial with a syringe, use it to lube O-rings in door and retract cylinders and fix small leaks, etc...) causes irregular and unreliable door sequencing in their valves.

WHAAAAAT?

How long have we all been using the two together without issues???
I have a giant scale F15 about 85% done and I had bought and planned on using UP2 + UP4 combo on gear (mode 3 landing, some doors stay open, some closed with gear down).

Now I am pausing and hesitating....do I listen to this news bulletin, buy an expensive all-in-one valve, or switch to electronic sequencer with multiple annoying servos and valves? Or do I go forward as planned and not think twice about it?

It's like hearing after all these years that JR servos don't work with Futaba radios even though thousands of people do it every day. Thoughts anybody as to which way to go? I really really really really like UP valves. I have already bought them and they are ready to install. They hold air, work right, are simple. Period.

But now there's a "warning" out there, so if I dont listen and something goes wrong......I will always look back and go "hmmmm....."

Advice needed from people with knowledge and experience. Thanks!
