Sure am looking forward to seeing your valve installation pictures. This winter I can't get my temps up above 170 and most of the time 160. I also have the 2006X. Looks like I am going to have to install the valve also. -------- Gary Blankenbiller RV10 - # 40674 (N2GB Flying) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=333943#333943 ________________________________ Message 2 _____________________________________ Time: 09:41:08 AM PST US From: Tim Olson Subject: RV10-List: Light(er)-weight Prop Lock In anticipation of an upcoming trip, I wanted a propeller lock. I spent a lot of time thinking about it, and finally found a solution that wasn't ultra expensive or ultra heavy.

What's strange is that there are 8 threaded screw holes, 2 pair at each prop shaft. But only 2 of the 8 are in place and safety wired. In the Owner's manual, they are called 'balance weights'. In one drawing it looks like a plate of some sort might be mounted under the screws. One other diagram 'suggests' safety wire. Otherwise, I can find no reference to them. Anyone know anything about this? I know this isn't enough information to easily picture this but I'm thinking someone is familiar enough to know what I'm talking about. It's weird to see 8 holes and only 2 screws.

Thanks, that's what I wanted to hear. Bill do not archive On 3/15/2011 7:57 PM, Linn Walters wrote: > > The screws hold balance weights, which are plates that mount under > pairs of screws.

I did a write up today but didn't get a great picture if the valve-only when it was mounted. It's pretty simple though. http://www.myrv10.com/N104CD/upgrades/20110314/index.html Hope that helps. A few weeks and I'll get a good long flight test.
