My Posts This: Topic Forum | What would happen if an engine exeeds its practical rpm (as stated in specification)?
One of my helis made a brief, strange high pitch sound almost every second during idle-up accompanied by slightly wagging tail, but not during normal mode. I doubt if the engine was overspeeding. It was an old OS 32F-H in that heli with practical rpm 2,000 -17,000 (compared with 22,000 of newer 32SX-H). |
