The mono to tail dragged market being the main objective. When Miles decided to pursue his own business, away from Flyer, the project stalled. I had an attempt to buy the Flyer Europa but Mike was a far more effective purchaser - quickly finishing the aeroplane and having the final stage of the Mod application approved. As l funded the original design work l own any associated IP, hence the reason for adding it as a product on our website. Our main business is design and stress analysis, as you are aware. I did a comparable analysis of the Swiss gear, making assumptions when details were not known. The Swiss gear is significantly stiffer in the longitudinal direction (braking and rebound loads). Our version, utilising the solid ma8n gear of the Europa tri, gives similar stiffness in all directions. The mass items are the main legs, sandwich panel webs and additional reinforcing plies that cover them. The reinforcements form a Y shape (from the pilot seat you see this shape >< under the knees of the occupants. The centre part braces the tunnel walls and gives a cont8nuous load path. I can supply photos is needed.

I have a monowheel owner very seriously wanting to convert to taildragger; in fact he won't put the a/c back in to service until he's done that. The Swiss conversion is dead-in-the-water as Luc Job (the original designer/manufacturer) says that he's lost the leg moulds, less still has any enthusiasm to produce any more legs. Will it be possible to licence one further Flyer conversion and supply the drawings? I appreciate that the gear legs are currently unobtainium from Europa and would need to be made up (in the States or similar). I imagine that LAA has the relevant details associated with the mod., but as IP owner, you would need to authorise any use of them.

Regarding Luc, l fully appreciate his dilemma, l had my CFM Shadow landing gear mould taken from the moulding company by a person masquerading as myself. Fortunately the people/company behind the robbery could not reproduce the (complex) layup. For the Europa Mod l was careful to make a plybook of all the plies needed, these are in digital form (IGS or DXF format) and can be used to create a kit of parts either by a nesting/cutter machine or via printed paper templates.. The installation instructions then give details of the sequence, orientation and initial 'touch' point of each ply. The LAA (in their typical way) wanted some additional plies, belt and braces - although this adds only a few ounces to the build. The main gear supply issue is a concern, perhaps you can update me via an email on the status of Europa supply chain, original supplier, etc?

Graeme - I have just re-fitted the engine mount to the LG frame on my XS (not sure if there is a difference in the relevant hardware between Classic & XS). I found that with everything assembled, the ends of the bolts were barely visible, more or less flush with the cup washers. I could just get the upper nuts started on the bolt threads, but could not on the lower bolts until I squeezed the cup washers slightly with pipe pliers. Once the nuts were started by hand there was no problem in getting them wound in by spanner until the drilled hole in the bolts started to become visible as the nut castellations passed them (had to adjust the bolt orientation so the holes were where they could be seen). My hardware (as called out on the inventory supplied from the factory) was: MT01/914 engine mounting frame AN5-41 Bolt drilled 5/16-24x4-1/8 MT02 cup washer - engine mount MT03/3 spacer - engine mount MT04 vibration absorber - engine mount AN310-5 Nut - castellated 5/16-24 My engine is a 912S - I guess that the mount is the same for 912S & 914, but I dont know about the plain vanilla 912. Sorry, I dont feel inclined to dismantle my mount again to measure my parts for comparison with yours :-) Hope this may be of some help but I guess folk with the Classic/9112 combination would be better placed to give a definitive answer. in friendship Rowland | Rowland Carson ... that's Rowland with a 'w' ... | http://www.rowlandcarson.org.uk | Skype, Twitter: rowland_carson Facebook: Rowland Carson ________________________________ Message 5 _____________________________________ Time: 04:22:10 AM PST US Subject: Europa-List: Re: Engine mount bolts From: "graeme bird" ah ha, that's it then, the drawing shows AN5-40 which is too short, needs to be AN5-41 that's 1/8th longer. thanks -------- Graeme Bird Kit 2 in build, Mono Classic 912; Kit 1 G-UMPY - Mono Classic/XS FFW 912S, Woodcomp SR3000/3W CS, trutrak Gemini 2 axis AP, PAW, PFLARM, ads-b out, 8.33khz, mode S, FP-5, Aera500, SD on Nexus, Smart A3 380 hours, 980t g(@)gdbmk.co.uk Read this topic online here: http://forums.matronics.com/viewtopic.php?p=491246#491246 ________________________________ Message 6 _____________________________________ Time: 05:42:59 AM PST US From: Rowland Carson Subject: Re: Europa-List: Re: Engine mount bolts On 2019-09-09, at 12:21, graeme bird wrote: > ah ha, that's it then, the drawing shows AN5-40 which is too short, needs to be AN5-41 that's 1/8th longer. thanks Graeme - yes, there seem to be some discrepancies in the manual. The text of chapter 1 of the engine installation manual (page 1-1, issue 2) mentions AN5-41 bolts, but the drawing (page 1-3, issue 3) on the latest PDF I have, still shows AN5-40. But before I go on, I realise that I completely forgot in my earlier message to mention the 5 washers: AN960-516L Washer flat thin 5/16 which are fitted to each bolt, and placed in combinations either between the aft cup washer and the LG frame hole or under the nut, to achieve the correct engine thrust angle. So, that washer stack also affects the length of bolt needed. Ive had a word with Inspector Pete Jeffers and he recalls an issue with the early arrangements for fitting the rubber (Lord) mounts. His memory (and mine too, now that it has been jogged) is that at some stage the rubber was found to be insufficiently compressed, allowing the engine to flop about excessively. The solution, we think, was to make the tubular spacers (part MT03) a bit shorter, which probably explains why mine had the /03 on the part number - it sounds as though there may have been a couple of tries to get it right! You need to be sure that you have the right combination of MT03 spacer length and AN5 bolt, so that the Lord mounts are correctly compressed when the nuts are fully tightened, and that the bolts are long enough in the first place to start the nuts on them. The bolts cant be TOO long, or the drilled holes will be beyond the castellations! We believe that the same combination of hardware is applicable to both XS and Classic - but a word with the factory might be worthwhile to confirm that. Id be inclined to check with the factory what length of MT03 they are currently supplying, to see if yours are different. Hope this is helpful. in friendship Rowland | Rowland Carson ... that's Rowland with a 'w' ... | http://www.rowlandcarson.org.uk | Skype, Twitter: rowland_carson Facebook: Rowland Carson ________________________________ Message 7 _____________________________________ Time: 10:23:07 AM PST US From: Roger Sheridan Subject: Europa-List: Flydat red lead Good Evening, My flydat two wire oil temp sender has failed (open circuit) & Id be keen to buy a used replacement off anyone who no longer uses their flydat. Regards, Roger ________________________________ Message 8 _____________________________________ Time: 05:26:48 PM PST US Subject: Europa-List: Re: Oil Usage From: "h&jeuropa" Roger, Several years ago Rotax issued a revised dipstick. It has square corners on the handle, not round like the original. The new dipstick requires a higher level of oil in the tank to be in the normal range (the flat on the dipstick). Supposedly this was done because of foaming characteristics of some oils. When we used the new dipstick we found that we had oil on the belly and used oil like you are seeing. We went back to the original stick and use only AeroShell Sport 4 oil and the problem was solved. Hope this helps.
