| Being thorough is never a waste of timeNow you know what isn't the actually the problem and you were able to isolate it to one specific area. Sounds like progress to me Honestly, a good look over of your power train at your current number of flights is highly recommended, but rarely heeded. You may have just extended the number of flights your heli will put out by checking this items now, instead of in the middle of a critical point in a maneuver.
Hmm, your YS filter indeed seems to be the issue from what you've explained. I think Bullseye1 thinks your are running a YS motor in your ship. But, think he may have something with the check valve. A quick check is to blow into both ends of the the filter. If you can only feel air coming out when you blow from one side and not the other, then it may be a check valve. If you are sure that it's not a check valve then simply take the filter assembly apart and check the screen. Ensure that there is no fuzz or lint built up or caked on the screen. You can use a can of compressed air to clean it off. I always install the filter with the screen closest to the carburetor side. Orientation of the filter is a small issue for "filters" as long as it definitely NOT a check valve. An easy way to tell if your filter is directional is to check for a reference mark some where on the filter itself or in the instructions that came with it. The mark is usually an arrow pointing in the direction of fuel flow to the carb. If you have just a screen inside the filter housing or there are no markings, then directional flow most likely does not apply as fuel will flow at the same rate on either side of the screen. A solid filtering element or something that looks similar a sponge could have a directional flow that applies.
Tell you what, if this is still unclear, install the filter that came with your heli. If the YS filter truely is the problem you will notice a performance difference right away. Note, the Align filter does have a directional flow indication annotated with an arrow. If you don't have that one. Make a trip to your local hobby shop and buy a filter. They are inexpensive and simple to maintain. Even the screen filters do their job quite well! "T" filters work well since they keep you from exposing open fuel lines to dust and debris during the fueling process. I had a leaning problem on my Evo50 for 3 months last year and changed everyhing twice and burned up 2 hyper50 pistons in the process. I over thought the problem and when I finally did check the filter element was caked with .5mm of dust and lint on both sides of the screen. Cleaned it and never had the problem again. Now I check the filter every 3 flights or so. Give it a shot. I think you'll be setting yourself up for a wonderfully trouble free weekend of flying. Hope to hear that this problem is resolved over the next few days.
