Hyperlite top plate angled washer

The [Pyro-Drone Hyperlite Evo](http://pirofliprc.com/HyperLite-EVO-5-3mm-Arms_p_3767.html) top plate is attached normally with a locknut and wishful thinking.
I printed a washer with a 30degree cutout to more firmly hold the plate in place.

I printed with no supports, in the specified orientation and used an exacto to clean it up. You can use a drill bit to ream the hole out.

I would suggest you use a needle file to angle the cutout on the carbon fiber to allow a deeper seat into the washer/bolt

(full disclosure: This is a WIP because I haven't been able to fly this frame yet as I wait for all my parts)
