      Hi Steven,
      
      Reading your reply just now, that explains why I did not contact you last night
      [Wink] 
      
      Even though I was aiming for an uncut panel, I am not dismissing your offer immediately
      because yours could be made into what I have in mind. In order to assess
      that, could you please post some pictures here so I can have a look?
      
      Thanks!

      I've made a few panels for my Europa (I keep adding stuff) and I just used an original
      as a template and cut one out of 1.5 mm aluminium. Perhaps you could take
      this approach using the club panel?

      This is all sounding very complicated.
      
      I was having cooling issues on the ground and on extended cruise climbs. I have
      the 13 row oil cooler too, but the builder had it mounted with a 30 mm gap between
      its base and the inside cowl face. So, a lot of air was just exiting the
      cowl without being forced through it or the water radiator. 
      
      I've just moved it down 30 mm so there is no gap between it and the inside of the
      cowl. I also made two plates that extend the sides of the aluminium cowl duct
      (that it's mounted to) down to the base of the oil cooler face and infront
      of the mounting points on either side to block off those gaps. Now, all the air
      that comes in through the stock rectangular cowl opening has to pass either
      through the water radiator or the oil radiator. There's no where else for it to
      go.
      
      Testing suggests all cooling issues have been solved. On the ground I was still
      within temperature limits after 15+ minutes at approx 2300 rpm. In an extended
      cruise climb to 5400 three days ago (23+ degrees at ground level) the oil temp
      remained at 96 degrees C and coolent (Evans) at 75 degrees C (see attached
      image). During the long low-power decent back to the airfield the oil temp remained
      between 90 and 96, but the coolent temp went down as low as 56.
      
      I've also fitted a thermostatic radiator valve fitted that only routes oil through
      the radiator when it reaches approx 83 degrees C. I'll take some pictures
      of the finished job and add them to this post.
      
      It will be interesting to see how it copes this winter and if I have to partially
      cover either radiator. I don't think this will be necessary, but we'll see.
      
      
      All the best.

      I have the alu-panels watercut, that was exactly my reason for asking for pictures
      to see it that would work  [Laughing]  Thanks for providing the hint though.

      Carl - there is a process for adding pictures but it requires human processing
      at the Matronics end so takes some time (and may not be available now anyway).
      
      However, if you have a DropBox, OneDrive, BT Cloud or iCloud drive you can put
      stuff there and then share a link on the Matronics list.

| Subject:  | Re: Cooling issues XS 914 on the ground | 
      
      
      Hi All,
      This subject is really interesting and I imagine some of the refinements/improvements
      that have been found to increase cooling for 914's could be used on 912
      powered aircraft without cooling problems to improve cooling efficiency and thereby
      reduce drag. I would very much like to see some diagrams, photos with explanatory
      notes when the experts reach some conclusions!
      John
      
      
      There are some historical reasons why the standard XS cowl       arrangement performs
      badly on the ground. When the XS was       developed from the Classic,
      the factory moved the engine up to       give them better prop clearance. This
      had the unintended       consequence of forcing them to use a smaller diameter
      spinner,       which exposed the propeller cuffs and roots. These cuffs thrash
           around during ground running producing no thrust and a large       amount
      of turbulent air. 
                
      The designers threw every known orifice at the new cowl; two       Lo-Presti's
      (popular at the time), two NACA vents (because all real       aeroplanes have
      to have NACA vents), two louvres to complete the       set and a shoe-box underneath
      to keep the radiator out of the cold       (I think someone added that
      for a bet). 
                
      The problem when ground running is that all this swirling airmass       is largely
      passing across the mouths of these vents - not into       them. The Lo-Presti's
      are positioned adjacent to the blade roots       and the radiator, positioned
      way back in its duct, is sitting in       stagnant air. It's not until the
      aircraft reaches flying speed       that the apparent wind comes more from
      the front that air begins       to enter the vents/ducts and the cooling improves.
      This is one       reason why Frans Veldman's front mounted radiator arrangement
      is       so much more effective. High twist blades such as the Woodcomp
           have been shown to give better ground-running temperatures because    
       they produce a much better airflow at the blade roots than many of       the
      flatter blade options.     
      I started with the prop/spinner and worked back. I lowered the       engine to
      the original Classic position - but maintained the XS       forward position.
      This allowed me to design a much larger spinner       to completely shroud the
      blade cuffs and most of the blade root.

      Carl,
      Likewise I have a 1cm gap between bottom of water radiator and bottom cowl.
      I experienced heating problems on the ground in Spain on recent trip to Gibraltar.
      I will be experimenting on my next trip to warmer places by closing this gap.
      Have been thinking of Nev Eyres new cowl? But am put off by work involved at the
      moment.

      What are you trying to cool on the ground?
      
      I have three fans in my panel, for example. They are barely enough.

| Subject:  | Re: Cooling issues XS 914 on the ground | 
      
      
      I am implementing a cooling fan for ground running. No temp specs, since the
      plane is in build....however, a cooling fan in similar arrangement works
      great on my motorcycle, so I figured it might work well here. Its an
      electric radiator fan for a quad Kart of of some sort, and covers approx.
      half of the oil cooler. The oil cooler, though offset from the water cooler
      (914 engine), is sealed to it in the area where they over-lap in front of
      the fan to promote airflow through both radiators (sucking air through the
      oil radiator will also do the same with the water radiaor...lots of work
      here to create tight-fitting air dams). Having the two radiators tight with
      each other will hopefully cut down on warm-up time during the winter as
      well. The fan is lightweight, cheap, and only requires a wire run and
      switch. Once verified to work, it will be made to be automatic on/off. For
      extreme cooling situations in flight with the airflow pushing and the fans
      pulling, the extra leverage 'seems' a no-brainer. I figure it won't windmill
      much if at all in the airflow while off, due to the resistance to the air by
      the radiators mounted in front of it. This arrangement would be much easier
      to implement with the radiators in-line with each other, but the offset is
      known to work well, and the decision had already been made.  More data will
      follow at some point..

      One of the first issues is the operating temperature range of the fan.
      
      Most of the Computer Fans, 12 volt and small enough to fit under the cowling, are
      rated to +40 or +50 C where we are talking about temperatures above that.
      
      There are vehicle fans but these are much larger.
      
      A manually switched fan was, is, fitted to the SkyArrow and the Operating Manual
      advised its use when the coolant temperature on the ground goes above 80 C but
      not sure of its source. The SkyArrow had a pusher prop so the airflow through
      the radiator on the ground wasnt great.

      Dave,
      
       Dimension of fan is approx. 100mm square, and is made for radiator cooling,
      so it should handle the temps.
      
      Put this into your favorite web search tool:'Electric Radiator Cooling Fan
      For Chinese 200cc 250cc Quad ATV Go Kart Buggy' 
      You'll find it...cost is about 15 US Dollars. Cheap enough to try.

      Hi all,
      
      Here are a few pics I took tonight of my installation. I'll need to take some with
      the cowl off. 
      
      Let me know if you have any questions.
