is not necessarily a bad thing however its an indication of turbulence induced

moving air rejoin, getting these two velocity streams to combine back together
more smoothly is a desirable outcome... one of my test pilots has just suggested
trying vortex generators; will be interesting to see if that has any
desirable affect... will be interesting to see just how much total drag can be
reduced and how that might be achieved!!

| Subject: | Europa get togethers in the US SE |
Hi,
Well, don't know if I will get in trouble with this but what the heck, I'll give
it a try.
Can you believe that after spending 4 years building my Europa and one year flying
it I have NEVER seen one flying from the outside!! I must correct that!!
For the last few months I have been talking to a couple of people in Florida that
fly Europas to see if we could get together once in a while. I fly every Saturday
morning for breakfast to locations around Central Florida and it would
be nice if I could personally meet other Europa drivers.
So I have create a Google Group called "US/SE Europa Aircraft Flyers" to see if
we can exchange messages about places to go and meet. Maybe not much will come
of it (I tend to be lazy when it comes to maintaining things like this) but
lets give it a try.
For now, you have to ask to join (to provide some level of privacy) or send me
your email and I'll send you an invite.
Of course you don't have to be a flyer or live in the SE or in the US (Heck, everyone
will be accepted as long as you have an interest in the Europa).
I think that anywhere in Florida and Southern Georgia are fair game for Saturday
morning flights.
I don't know much about this Google Groups thing but it was the easiest for me
to set up. I think you can go to the group web page (I think you need a google
account to go there directly) at:
https://groups.google.com/g/usse-europa-aircraft-flyers
or send an email to:
usse-europa-aircraft-flyers@googlegroups.com
and request to join.
Well, lets see what happens.
Chris

Must be colder where you fly; got the opposite challenge here; place is totally
flooded out now with raging orange waters... so i drank more ballantines and
coffee this morning and spent the day playing with the new science toy... between
a clean featureless airframe and my built example is roughly 180N more drag
and 240N more lift... this afternoon played around with the lower engine cowl
flap and closed in the undercarriage which improved the air stream under the
belly... 30N of drag was reclaimed and 60N of lift was given up with mods to
the cowl vent; the inverted foil added produces 35N of negative lift... enjoying
seeing the numbers come back!!

| Subject: | Re: Arplast Propeller problems |
The electric motor of my Arplast PV50 motor failed (again !) recently. In my experience, it would seem to have a life of about 250 hrs between failures. From the research I did last time this happened, it would seem a 12V model is available, but perceived wisdom is that this does not have the torque available from the 6V model, and therefore does not have the necessary power to rotate the blades. Maybe this explains the relatively short life of the standard 2224U006SR model. I tried to source a new motor from the UK distributor www.ems-limited.co.uk Although they were very helpful, the best delivery they could offer was 9 weeks.
Fortunately, courtesy of Italianjon of this parish, I was pointed in the direction of a German Company who had them in stock, with a immediate delivery. Even from Europa, the new motor arrived in the UK in less than 14 days. For anyone looking for a replacement motor, I would recommend this company. www.fechtner-modellbau.de

Pete,
Looks like you repainted C-GNPZ. Looks really nice!

Starting thread for this week. Snow is off the runway and warmer temps forecast
for this week. Hopefully, N241BW will make first flight for 2022!
