    Not to resurect the old thread, but has anyone considered, or known of an available yaw damper system that would work on an RV-10? Perhaps it isn't needed, but it seems to me that folks with airsickness tendency are most sensitive to yaw.

Yes my horns were uneven too in seemingly all directions. So much so, I found it difficult to maintain the prop edge clearance on one or the other. I obsessed so much about it that with the help of my Tech Counseler, we re-engineered it a bit so it looked like his Pitts.

I guess it really should not matter too much as long as they're drilled accurately. I'm really anal about things like this..ugh! Unless someone thinks otherwise, I'll move on and live with it.

I have some 2-part epoxy, but I am worried about discoloration and odor especially during initial flight testing. Alodine seems to be a good solution (no pun intended) as it should be odorless when hot.

    Robin, Take it from an old electronics guy (short on airplane experience, but lots of automotive) the statement that the battery charger output is not "conditioned" is correct. -- But, the battery itself acts as a very good filter for the spikes and sags from the charger. the likelihood of damaging your avionics is very small. I would not hesitate to operate it that way.

I was told that hooking up a battery charger to my battery while running the avionics is a BAD idea as the electrical current out of the charger is not "conditioned" and the power spikes could damage my avionics. Whoops... Seems to me that for the price of a mid-sized luxury car made in Stuttgart there would be an inline electrical conditioner as part of the avionics suite. Back to my question. I have placed several 12V cigarette adapters including one in the baggage area plumbed direct to my primary battery - hot all the time. What is the best way to continually provide "safe" power to my battery to support my avionics for extended use on the ground?

    I painted the baffles on my Pitts 25 years ago with Imron and they still look good except for some minor discoloration next to the cylinder heads. Always had to be careful about scratching them though. A local shop anodized all the baffles for my -10 for $75. Really looks nice, and I suspect they will be much more durable than paint.

    I had my baffles powder coated by a local outfit. If I remember correctly there were 9 pieces. Was able to match the "goldish" color of the engine that came from Mattituck. Not yet flying (but getting close) so I don't know how it will stand up to the heat but the powder coaters assured me that their paint was "good" to 500 degrees. We will see.

    I used Imron on my RV-8A. 400 hrs and it still looks like it was just painted. I'll probably use PPG Concept (single stage) on the RV-10 as I have found it to be an easier product to use.

    Subject: Re: Rudder Peddle Position
    From: "tomhanaway" <tomhanaway@comcast.net>
    One other question along this line. Is the forward position (closer to firewall) position of the rudder bracket for taller people or shorter? I'm learning not to assume the obvious. For example, having the rudder bracket aft would put the pilot's body and head further back in the cockpit and thus more headroom for the taller person. Or is it the obvious, shorter people set rudder bracket in rearmost positon. I'm 5'10" and will probably be ok with either and prefer to keep my C.G. forward. However, my wife is 5' 4" and plans to fly the plane also. Thanks, Tom H. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=184798#184798

    I couldn't remember the gotcha but now I do. My horns where different lengths as well. When looking at the horns from behind, make sure to measure and drill from the shorter side into the longer side. I got lucky with this but I know at least one other builder had a problem here. If you measure and drill from the longer side, you may not have sufficient material under the hole on the short side.

    Subject: Elevators
    Thanks Dave. I drilled them today. Here=92s what happened. The aft horn by chance (per plans, drill the aft one first) was the long one. Ugh!!! Fortunately, the horns were only about 3/16=94 different in length so I still have 1/8=94 in edge distance on the short one. I wish I had seen your post earlier today. I would have drilled the short one into the long one. Disappointing but not the end of the world. It=92ll work. I checked my trusty Aircraft Handbook and the edge distance needs to be =BD or more of the fastener diameter. I=92ll have to keep an eye on it. As far as one being aft of the other, it was only by about 1/16th. So I could have drilled the forward one and I would have a much better edge distance for the hole. Oh well. When I build my second or third RV it=92ll be more like a Swiss watch=85.Those Saint RV=92s must be pretty nice! Thanks for the tip. This should really be archived. I didn=92t search, maybe it is.

    From: "Robin Marks" <robin1@mrmoisture.com>
    Jack, That was my thinking exactly however a $130.00 power supply was cheap insurance against the potential claims that I voided any manufacturer warranty. The panel was too expensive & I am too close to first flight to get stuck in a pissing match with a manufacturer where I am the one with the most to lose if something electronic were nonfunctional regardless of the cause. It's really about all the $ tied up in the panel at this point. Thanks for your note, Robin
