Hi,
what do you mean about the hub locking up?
I just bought a DA85 and put it on the test stand for initial break-in. First tank of 800ml went fine using a 26x10 Menz Wood Prop.
It started right up and ran very well for the first run.
2nd run was a different story. Starting was no problem but after about one minute, the prop flew off with all 6 bolts sheared at the hub.
I still cannot figure out what caused it. Needless to say, it has been returned to the shop for inspection and replacement of the hub.
Anyone have any ideas as to what caused this? My retailer says maybe it was caused by the bolts coming loose. I own a DA 50 and 100 and have never had this happen.
Thanks for any clues that might help prevent this from happening again. Even at idle you can't imagine how far a prop flies from an engine.
