Now I'm doing the final works on my EUROPA Classic Kit No. 242 in order to get it to the sky next year hopefully. While I'm installing the 'stall warner' -Mod 61B- I'm faced with several questions which EUROPA Aircraft Ltd. GB (Karen Ward) could not answer fully yet. Perhaps some of you who installed this Mod 61B already could help me on my following questions: 1.) I know the instruction on Mod 61B-Classic says that the hole of the stall warner should be 52'' (1321 mm) out from the aircraft centreline, so far so good! I actually would like to know whether this point 52'' is obligatory or could it be 70''?? And if it must be 52'' what is the reason for this exact point?? Does 70'' from the aircraft centerline not work accurately? And why not? (Because I installed already an empty tube to the 70" point at the beginning when manufacturing the wing!!) 2.) I understand that a vacuum appears on a special point below the leading edge if in stall configuration. But to my past knowledge in air-pneumatics on the leading wing edges there should still appear a pressure instead of a vacuum when the wing comes to the stall. I looked into many good aeronautical text books containing the theory of stall characteristics but I always found a pressure there!? I would like to understand the airflow = pressure or vacuum = on the leading wing edge in stall configuration on our type of wing. Could someone give me some hints, where I could see/read the theoretical background on this subject? Perhaps on the internet? 3.) In the retrofit installation instruction (Mod 61b Classic) it calls at page 5 for a 'W39 probe' to be installed at a special angle as per the 'hole template'! What kind of 'probe' is that? Is it just a small brass or aluminium tube of 3 mm inside diameter, or is it a special manufactured 'probe' with a sophisticated inside configuration? Is it a must buying it, or could I manufacture it myself? Helpful hints would be appreciated.

Jan de Jong ________________________________ Message 6 _____________________________________ Time: 09:49:27 AM PST US From: "David Joyce" Subject: Re: Europa-List: Stall warner-retrofit installation-classic (- Mod 61 B - Classic) Jan, I suspect that almost anywhere not in the prop wash and not close to the tip would do. You end up by adjusting the pressure sensor head to sound off at a chosen speed above the stall anyway and I guess that adjustment would be valid anywhere in the central wing section. I suspect that the 52" bit is the shortest length (to make retrofit as easy as possible) that is reliably clear of prop effect.

Its just a short length of around 3.2 inside dia tube with a smaller tube fixed in so the pvc tube goes on. The kit did seem rather expensive seeing its just an RS sensor/switch but then the air connectors are fairly pricey and Europa have to survive somehow. I didnt see the point of providing the wire loom as each installl will be different. -------- Graeme Bird G-UMPY Mono Classic/XS FWFD 912ULS/Warp drive FP Build nearing completion Read this topic online here: http://forums.matronics.com/viewtopic.php?p=356570#356570 ________________________________ Message 8 _____________________________________ Time: 11:11:09 AM PST US Subject: Europa-List: Advice on Control Locks and Pitot / Static Covers From: Carl Meek Hi Everyone, Can anyone advise where to acquire rudder control lock, pitot cover (2 pitots) and static cover (2 statics) for a europa?
