Bryan,

If you didn't want to mess with the PSRU flange ( especially if it has threaded inserts) you could use sleeves in the prop hub and use the 3/8" bolts.

I’m a novice when it comes to props. So, could I get some advice about the following prop that a guy has for sale.

I have a Renesis with the RD-1C (RV 7). Plan on using the rotary cowl.

The prop is question is a 3-blade MT.  Model MTV 7-C-187-139.  that’s 73” diameter, electrically adjustable.

Firstly, the bolts are 7/16 and the PSRU is 3/8^th.  Would there be a problem opening the holes?

Secondly, the website (MT) indicates that 160 is max HP for the prop, but it also says that 175 is max diameter.  This one is 187cm (73”).

I have sent an email to MT regarding this, but want to let it get kicked around here on the forum.

Lastly, in the construction manual, Van’s doesn’t recommend aerobatics with an electrically adjustable prop.

Thanks in advance for your replies.

Bryan
