Hi Scott,

I emptied the fuel tank as you indicated and obviously there was a improvement. Still the plane tilts down by the nose but not as bad as it was before. For sure the fuel was adding a lot of weight.

Now I have another problem. Every time I try to start the engine the bolt that holds the propeler becomes loose. The first time it happened I thought maybe I didn´t tightened it hard enough, so I did it again making sure this time it was pretty tight. Once again, as soon as I applied the starter to the cone on the propeler it got loose again, so much so that the propeller just comes off. I thought about putting a preshure washer but there is barelly any thread left for the bolt, so the washer won't fit.

Has anyone experienced something like this with your Alphas? I have added a few pics so you can see how I am fitting the propeller, that to me looks exactly as the manual indicates.

Thanks for your suggestions.
