In an angry world with little online civility, VansAirForce.net exists as a small, non-algorithm driven, honor system webazine and forum trying its best to be a laid back virtual watering hole for builders and pilots of Van's RV kitplanes.  We roll polite, don't talk politics, don't employ attention engineers or record keystrokes or clicks.  Hopefully you leave VAF a little happier and motivated than you arrived.  Brought to you by Doug Reeves.

11/30/2023.  Issue #5,961. (previous day's news).    RV-4 Status ...Sanch627 Moving right along.  Just a few pics of where I'm at. Chris Santschi RV4 #4633   Wings Installed ...msstahl Had the family over for Thanksgiving. With the crew successfully drawn in they were put to work assisting with the initial wing instillation.   Exhaust staining? I'd like to continue learning about engines and diagnosing problems. I am used to seeing white staining near an exhaust gasket, but what about this reddish/pinkish staining. Is this a leak from a crack?   2 RV7A POH Questions 1. Why fuel boost pump on for takeoff (besides the obvious possibility of failure of the primary pump). Would the boost pump alone keep the engine producing takeoff (or less) power? 2. Why fuel selector "Off" after engine shutdown?   PIREP on -4 Rudder Pedal ...Bill E. OP Pic: Bill E. PIREP A couple things It looks like your clevis straps for the rudder cable are entirely on the inboard side rather than being on each side of the pedal horn. That should be made correct, and it will buy you a little clearance, I made my straps from .032" titanium, so they are very thin. Also, the bottom attachment of the master cylinders that came in my kit are machined on the inboard side to allow the nut and bolt end to be recessed and not strike the tunnel. The bolt head is on inside of the pedal horn. These 2 items will eliminate some of your hang up issues. You have to zoom in on my picture to see the differences. I also wear a size 12W shoe, and fly with VANs checkerboard slip-ons, Hey Dudes or boat type shoes. The racing shoes are nice, probably best, but I don't like walking around in them.   Low EGT at power I need to ask the forum if I have an issue here. I have 3 photos attached showing CHT/EGT with #4 cylinder having unusual readings. The engine is a o320 150hp. At full power, the EGT is unusually low 1159 and 349 CHT. At cruise power, EGT is closer to other 3 cylinders as well as the CHT. At low power settings, all temps are close to each other. Full power settings in climb is where the temperature gaps are at the highest. All the variables are on the photos and looking for guidance or is this behavior normal?   Laser Cut Parts List updated; Service Letter SL-00091 published Van's Aircraft has published an updated Laser Cut Parts List (R6), which reflects further analysis on parts manufacturing dates and reclassifies certain parts.   SL-00091 REV1 Laser Cut Parts and Certification of Aircraft Refers reader to the updated Laser-Cut Parts List as well as the Laser-Cut Parts Engineering Evaluation document; and addresses the use and inspection of these parts.   Updated Factory Hours ...will leave this up here for a few weeks.   Business Update 10/27: 1900Z ...factory.
