I ordered a new starter shaft for my Velocity 50... I was glad that the 2 screw squeeze one was out of stock and the original one was back.
Who ever designed this.. and thought it was a good idea... and all the others responsible for thinking it was a good idea and letting it through... well...

You're whats wrong.

Now for the good news. I ordered this:

It is not the same as the original part pictured. The shaft has a single flat spot for one of the grub screws and a little bit away it a hole in the cup for another. This is an improvement.
Now as long as the material isn't cheluminum, I will be quite joyful. Oh hell, ill still enjoy it while it flies...
