I don't know the size you need to ream.

Fox puts out a reamer that is staged from 8mm to 10mm to 12mm. I use it to ream out my props for my Moki 180. It is the biggest one I know of. The handle is removable, which allows me to use a drill press.

BTW, if you are playing with engines the size of the MVVS 1.6 you really should invest in a drill press. You can get an inexpensive one from Harbor Freight for around $50.00. Here is a link to one:

It is a 1/3rd HP 1/2" chuck desk top model for $49.99
