Accepted proof of MPH

[FurryOnTheInside]

I had the darn piston pin "C" clip snap off at 10,000rpm, about 44mph with the stock gearing.
I was using this type:

And one of the legs snapped off.
I highly recommend getting better "C" clips for high rpm stuff;

Like what? Those look good to me (a little knowledge is a dangerous thing). I had the top type in my picture in my eBay engine kit but I like things to be not annoying so I changed to the bottom type for ease of getting them in and out.

The one thing I don't get is why do these kinds of apps need permission to access pictures and media files? Could be my tech ignorance.
