    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! -------- Marcel Zwakenberg XS TG || 912ULS || PH-SBR Read this topic online here: http://forums.matronics.com/viewtopic.php?p=459860#459860

    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? Read this topic online here: http://forums.matronics.com/viewtopic.php?p=459861#459861

    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. Carl G-URMS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=459862#459862

    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. -------- Europa mono Nr 192 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=459869#459869

    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.

    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.. Greg Fuchs 914 TRI -----Original Message----- COOLING FAN FOR GROUND COOLING. Has any one experimented with a fan? Dave Park

    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.
