The difference between the two will only make a minor difference in your reading. If you have access to an optical tachometer, you can verify your meter reading, as meters do tend to vary a bit. > Mike Duane N377EA > Europa XS Conventional Gear > Chandler, AZ, USA > > Sent from my iPhone > > > > On Jan 19, 2021, at 2:20 AM, Rowland Carson wrote: > > > > > > > > Im wiring my Europa XS with a 912ULS engine.

Does anyone know if using the 220 resistor Ive got would make the UMA tacho unhappy? And conversely, would using a 270 make the MGL instrument unhappy? > > > > in friendship > > > > Rowland > > > > | Rowland Carson ... that's Rowland with a 'w' ... > > | http://www.rowlandcarson.org.uk > > | Skype, Twitter: rowland_carson Facebook: Rowland Carson > > > > > > > > > > > > > > > Read this topic online here: http://forums.matronics.com/viewtopic.php?p=500351#500351 ________________________________ Message 3 _____________________________________ Time: 06:50:02 AM PST US Subject: Europa-List: Re: Instrument Panels From: "n7188u" great idea Alan. Make me wonder if using a more robust 3D printing process such as the HP multifusion an actual useable 3D printed panel could be made. I think I would like to give that a try. So yes, if you can share the files I would appreciate that. Can you export them to DWG or DXF ? (so that they work with the CAD packages I have).

Unfortunately for me my taildragger (a Kolb Firestar) is not a three point landing aircraft since in the ground it's attitude is well beyond the stall point (and the high drag to low weight ratio of the plane killing the speed in a second). Trying to three point my Kolb always results in very hard landings. When I got my endorsement I was trained by a CFI that absolutedly hated two point landings (he flew Pitts and discouraged landing that airplane two point). When I used to fly gliders it was very common and a joy to plant the tail first in the ground before the main touched. But this was so because there was such a good margin between the attitude that allowed the tailwheel to be lower than the main before the airplane stalled. I was hoping for that to be the case for the Europa but per your posting I guess that may not be the case although I have to say I have seen pictures of Europas landing with a significant tail low attitude on short final. I guess that is as you refer to some people coming in slow on approach but I can see why that would not be the ideal case on a first flight. Well, I'm getting ahead of myself since not quite ready to fly yet. Good posting though. I will for sure talk to you when the time comes. I include a picture of my plane when I took it out for some engine running and taxi test this weekend. I'm so happy its getting there!
