So I killed my first spur gear last night. Landed upside down pretty hard without the body on, turned it over and it went no where. I only quickly looked at it today and saw this, when I pulled the engine off I also lost one of the little bearings on the clutch bell and the C clip and washer that go after it. Only 1/4 of the spur gear teeth are broken, and barely that bad. Engine bolts were fairly tight, and the engine mount (which I haven't touched ever) were still all tight. Did I land so hard I moved the engine mount too?
