Subject: | Propeller Sizing |
Hello Group
Firstly apologies if this is a repeat as I was not clear if the original had sent.
I am currently changing the engine on my classic mono (const no 33) from a Rotax
80HP to a 100HP unit.
The original engine was fitted with an Airmaster 3 blade VP fitted with Warp Drive
blades (T12981) giving a swept Dia of 62". I am very keen to retain the Airmaster
hub and have been advised by Airmaster that this set up should work for
the 100HP engine.
However I have also been advised that these blades will not be suitable and should
change to Warp Drive blades giving a swept Dia of 64".
My question is are any of you classic mono flyers out there using a 64" prop on
an Airmaster VP hub and has it worked well?
Thanks
Mike

Hi Mike,
Your choice of propellers is governed by the LAA. They have a document 'LAA Propeller
Type List - PTL/1 listing approved props for the Europa/engine combinations,
getting approval will be easier if you stick to something from the list.

Good afternoon everyone,
Could someone please clarify what size are the screws that hold the
engine cowlings on, hold the wheel spats on or hold the inspection
panels on the wing underside?
Looking at the manual, I think they are 3/16" but am not sure what type
of thread they are.
I need to replace some of mine as the heads are getting slightly worn.
Thank you
Arwel

Thanks for the reply Dave, I am aware of this list but it is not exhaustive
as I understand that there are more options that have been individually
approved.
I am also in contact with the LAA who thought that a request like this might
be useful.
I am hoping that someone has indeed fitted either a Warp Drive or other
blade type of 64" on an Airmaster hub to their classic mono.
Cheers
Mike

Hello Arwel,
The cowl screws are usually countersunk with a Tinnerman washer, the inspection
hatch screws are dome-headed and the spats are also cross-head screws - but i
don't recall the type or length. They are all 3/16 UNF from memory.
But the absolute best way to identify any part on your Europa, is to go to the
appropriate section in the Europa build manual and there you will find the description
and part numbers listed for e.g. the fasteners. You will need to register
(once) to view all the manuals and modification listings. See:-
https://www.europa-aircraft.co.uk/support.html#register
And for buying bits from Europa, the email and contact number listed below, should
be used now:
enquiries@europa-aircraft.co.uk or call +44 (0)1603 542545
Hope it helps . . .

Great posting theme idea Jim.
I'm changing all my rubber components at the moment and just completed taking out
and refitting the engine to change the engine frame rubbers, and the fuel hoses
etc (Gates Barricade SAEJ30R14 - which is a bit hard to find and expensive,
here in the UK).
Took the opportunity whilst i'm working in the tunnel to overhaul my Mono UC as
well - disassembly, clean and inspect and checking e.g. linkage bushes before
lubing them up and reassembling then resetting the 79mm gap.
Fresh oil hoses and re-purging the oil system, then the coolant system refresh,
next.

Europa uses AN screws and bolts for the most part except in areas where the particular
engine fitting or mount is either Metric or SAE. It's important to get
knowledgeable on hardware and have spares.
Counter sunk screws differ. Most hardware store are 90 degree so they protrude
and fit poorly causing cracks eventually. AN hardware countersunk is 118 degrees
for a flatter finish and it fits the Tinnerman washer precisely.
Note: Buy a 118 degree Permagrit countersink for use on the aircraft. If you are
a second hand owner, and are clueless of how the builder built the aircraft
due to poor documentation, you only have the build manual to go by, so reading
and study is essential.
For your Europa supplied screws they are (#10 which is 3/16 inch and is known as
10-32). I use AN507 which is also known as MS24693 MACHINE SCREWS (AN507 in
stainless steel). I use 1/2 for around the sides (MS24693-C272), 5/8 for the
top cowl circumference, and down the side side of the lower cowl and 3/4 to 1
inch for the very bottom of the lower cowl depending on your particular nutplate
installation. Available at Aircraft Spruce and other aircraft supply houses.
Make a list. Everything that goes on or off will eventually need to be replaced
or wear out. My method is attached for logging my expendables. As for my screw/bolt/nut
list, I have trays full of every screw I have used during the build
of the aircraft. I make sure I have a few spares of all the cowl screws,
wheel pant, and access panels I use on my aircraft in a tool bag. My website
has my tool bag contents in the techniques section and many are on the Europa
Club Website.

Bud Yerly

Mike,
My website has how to select a prop for your Rotax.
The 62 inch Warp Drive Taper blade is fine for most 80HP Rotax powerplants.
The Rotax 912ULS 100HP has significantly more torque and the 62 inch tapered blade
is not very efficient. My US folks were very disapointed with trying to use
this short tapered blade on the 912ULS in both the Airmaster and the fixed
pitch versions.
The blade angle will be quite high and takeoff will be shortened, climb will be
less and the cruise will be about 5 knots slower. The 80HP Rotax won't spin
a wide chord 64 inch without lugging the engine down. There is just not enough
torque. The tip at takeoff is not able to bite for good performance.
The LAA recommendations is for the Warp Drive Standard (wide chord) blade of 64
inch for the Europa (which limits the length for the airframe to 64 inches) and
was the standard Airmaster for a number of years. The 100HP Rotax has the
higher torque and can spin the wider and longer props with authority.
Also available for the cost of a blade change is the Sensenich high speed blades.
Whirlwind has a blade but due to Covid lockdowns in California lead time is
many months. Sensenich and Warp Drive are made in free States so production
and labor issues are not a major problem for delivery at this time. Airmaster
will build you up a set of blades and ferrules ready to mount. It will cost
you but it is worth it.

Subject: | Re: Trim setting question |
Hi Kingsley,
I am not an aerodynamicist, so this is my uninformed explanation why the
trim tab deflection is desirable:
1. Nose down trim is commanding the tailplane to provide lift, this
slightly reduces required wing lift along with wing induced drag, so
it=99s a good thing.
2. If you move the CG forward and tailplane lift required is
reduced, the wing induced drag (to maintain level flight) will
consequently increase - not desirable.
3. To produce the desired tailplane lift without tab deflection
would require an internal trim spring or reduced counterweight and now
you=99re the test pilot!
Interestingly some Jodel models have all flying tails that are only
partially mass balanced, so reducing that lump of steel might work, but
I won=99t be trying it.
Cheers,
Roger

Subject: | Re: What did you do with your Europa this week, 12/20 - 12/26 |
Busy putting some weekly flight time on my Classic these days (an hour at a
time lol). Have been troubleshooting my new CYA100 AOA which has a habit
of going intermittent, and it's hopefully a connector issue not requiring a
full rewire and removal of panel etc. (I had reused the builder's original
now removed and replaced inop AOA's fuse/wing-wiring). I love flying in
the winter - smooth and great performance. That said, I've spoiled myself
with a heated hangar - which I need to justify (propane is crazy expensive
these days!) so the more flight hours the better. So far about 70hrs since
getting it back into the air in September after a main frame repair for a
bent pivot tube which I have now re-enforced with a truss... along with a
laundry list of "make it mine" mods/improvements/fixes.
Just added an unedited (read boring) vid to my Youtube channel with the
latest AOA recal. Normally my airport does a great job with clearing
the pavement, but this flight was on glare ice surfaces.... makes
tailwheeling really smooth and easy peasy ;-) but runups not so much lol
Generally I find that if I fly the AOA to the runway I can reliably nail
the short full stall landings - luv it. Gives me more confidence than the
ASI how much I've got left - leaving me generally too fast. Now if I could
ensure it is reliable :-)
