Care to share any of that info!! The grass clippings in the intakes has been my ONLY problem! Not really a problem, YET ! I put my screen in the duct at the point the removeable duct attaches to the stationary duct. The removeable piece actually traps it on the other piece! Works great except for this grass thing. This time of year in Georgia the grass turns brown and small clippings come off whether it has just been cut or not. I have a small vacuum and have started vacuuming it out after flying! I don't see any way to stop it! If the screen was at the front of the duct you could just brush them off but I don't see any way to mount it there without affecting the air flow! I you figure out a way please let me know!! I installed the Jet1A gear and it works great on any terrain!!
