If we could all get a test stand to fly we'd be in business I guess!

Listen, the felt clunk didn't work for me in the small tank just as it didn't work for a select few others..Maybe it was the aggressive flying as I was testing the 10GX and the Meridan plane to see what both could do and how well they perform.
If the felt clunk is working for others fantastic ! It does work for me in a larger tank on the 15GX. and 33GX.
The sintered clunk works fine for me in the smaller tank. It stays at the bottom ,moves side-side ,it filters the fuel and it passes no more air bubbles to the carb than the supplied felt clunk. As I said earlier. a sintered clunk will clog before a felt one and I anticipate that to happen around 2025 or 2030.
