One of the YouTube posters pointed out that in the first clip there was no onein the back seat but yet there was footage taken from there. Movie cameras backthen were a rare commodity so shots from two different airplanes requiredlanding and transfer so the performance was, most likely, a publicity stunt. Regardless of the setup, it was still a spectacular feat of bravery (or stupidity).A neat clip, all things considered.DaveRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Fri, 24 Aug 2012 07:18:24 -0700 (PDT)

Rick;You can get an idea of intake area by looking at William Wynne's setup on his Pietas a starting point. Some pictures here:http://www.flysquirrel.net/piets/WWPiet.htmlThis one is a good starting point for two reasons: (1) his scoops were rectangular,so you should be able to estimate the intake area pretty easily, and (2)his airplane was based in Florida, so if the cooling worked there, it should workanywhere.--------Oscar ZunigaMedford/Ashland, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Subject: Pietenpol-List: Re: A65-75 Tach discussionI can add a bit of experience with the traditional mechanical tach and the 90 degree drive. I have 135 hours on my Piet in 15 months, and am on my third angle drive. I think I have the problem licked now, but there appears tobe a delicate balance between undergreasing and overgreasing the tach drive. And, the lubrication of the cable is also an issue. I found an excellentspeedometer cable lube at the local NAPA auto parts store that is doing the job on the cable. It's a light machine oil with graphite in it. Nasty if it leaks out but very effective lube and seems to penetrate well. I have an 84" cable with a lot of bends. Taking the cable loose at both ends periodically and dripping in some cable lube is a part of my regular maintenanceprogram now. I think I made the mistake of putting addtional white litium grease in the angle drive, which eventually caused more drag in the drive than lubrication, especially when it's cold. The third drive was installed about 45hours ago, and I have't had the needle bobbing like I did with the previous drives. When I installed the latest one, I added no additiona grease beyond whatcame in the unit. Long story short, if I knew when I was installing the instruments what I know now, I would have gone with the Westach tachometer, particularly the one that uses the generator off the tach drive on the engine. If this angle drive gives me trouble in the future, that's the direction I'm going in.

Hi Rick - I think I did what Oscar said & based it on WW's intakes. 4.5 inchessounds about right. The highest CHT I ever saw was 360.--------Kevin "Axel" PurteeNX899KPAustin/San Marcos, TXRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________
