that crap Evo 100 NX engine. It was a suggestion to try to fix the problems I was having with this setup. So, I went ahead and replaced the clunk. It did not fix the problem but I left it in.
CGr.
I think I remember that thread too... that's the reason I started using them as well. Never got the Evolution 1.00NX to work right, but I'm about to try again... this engine really bugs me...
I didn't quite believe in those clunks until I had a foaming issue in another plane which the Dubro clunk eliminated. They also prevent problems if your lines are just long enough to contact the back of the tank on acceleration.
I had a plane that I had setup with what I though was enough of a gap, and it turned out that as it accelerated the tubing would stretch just enough to let the clunk contact the back of the tank, causing an overly lean condition and deadstick.
The Dubro clunks prevent this from even being a possibility.
