Jan,
Thank you for providing this weight analysis. I am very interested in the Beringer
stuff for the mono but I have some doubts about the weight savings they claimed.
What type and size of tyre was installed on the Europa wheel you weighted
at 10.8 kg?

Remi,
I weighed the bits on the picture together, making 10.8 +/- 0.1 kg.
The tyre is the original Europa one. It says:
TITAN, tube type, 4 ply, 8.00 - 6, turf glide, not for highway use.
I wonder how many flyers have used this tyre in operation and for how long.

Thanks Jan,
As far as I remember this Carlisle tyre weighs about 0.7 kg less than the AirTrac
8.00-6, when new. Based on your figures, that means that for those already
using the AirTrac the weight saving provided by the Beringer kit would be in the
2.2 - 2.7 kg range. A significant portion of this saving (0.9kg) comes from
the removal of the tube, as this is a tubeless system.

Remi,
Thank you for the tyre weight information. I didn't know the Titan tyre
was so relatively light weight.
B.t.w., guessing at the weight of the omitted parts in both kits I
believe the ultimate weight savings, using similar tyres, will be closer
to 2.2 kg than to 2.7 kg.

I am going to convert my Mono G-LDVO to Trike, Nev has been primed! For the job?
As a result I will have a mono trailer for sale, this trailer was renovated
and re-galvanised by Nev when I purchased it, looking for 700. Will not be available
until November December?
I will therefore need a trike trailer if anyone has one available to sell?

I would like to hear pilots views on what technique they use for repeatable
good landings.
I have been using 60/65 kts on finals then flaring at about 20
foot, attempting to keep the aircraft close and parallel with the ground
with a gradual nose up attitude.
I have now been introduced to adding a squirt of power during the final
landing phase to improved elevator authority which should give greater
vertical control.
I would welcome views on this topic. John

John,
Monowheel technique.
65kts on final. 55kt over the fence/threshold, a two stage flare due to the f
ast wing, first to arrest the descent, pause, then second, flare slowly, bri
nging the stick back to contact main wheel, then bring the stick back fully a
nd brake, keep straight with rudder anticipating turns from side to side.
SHORT landing, aim for a point, speed 45kts over the threshold, place aircra
ft on the ground at the first flare and hold stick fully back, brake.
20ft too high, closer to the ground to arrest descent, power not usually nec
essary in flare unless a big bounce occurs then yes it is good.
Works well.
Cheers,

Hi Graham.
That all sounds logical to me, but I am just wondering why some Europa,s have two
blades and others three, as it seems three would be the best. However i notice
in the hanger at Headcorne many performance and aerobatic aircraft are fitted
with a two bladed prop which caused me to think why.?? The only reason i
would think that its more stronger but was wondering if there were any other benefits
?

Hi Alan=2C
I think the vast majority of GA aircraft have 2 blade props.Mine has 2 blad
es=2C or at least I did until recently. I chose it partly because of the mo
torglider wings for better visibility when feathered. Other advantages are:
cheaper=2C less weight=2C it is much easier to remove the bottom cowling
=2C it sounds better=2C easier to ship if you need an overhaul.The only sna
g with the Europa is: because it has to be longer it is unsuitable for the
mono=2C and the trigear needs to have the nose raised a bit.It is just as s
mooth as the 3-blade=2C so long as your carbs are properly synchronized.

Hello All.
This may be of interest to you if your like me with only a fiver and 50 minutes
to spare.
Its a control lock, effective and very simple to make in 50 minutes.
Ingredients.
Just a length of 5/8 Dowel , Two copper T pieces, the ones with the solder in are
slightly longer, you could use one of each as i have.
Couple of pop rivets , bit of Velcro and Yellow tape, touch of Araldite, and a
lick of paint,
( pop in the oven for 50 minutes)
I like mine to push against the seat absolutely no movement, for storage it is
clipped up on the cockpit ceiling , but you could shorten it with a cap just
beyond the Velcro straps,
I could not remember if the controls are locked in Neutral or Fully down, so i
stuck two Velcro straps on, take you choice what's best to uses.
Weight 200 grams.

| Subject: | Fixed Aileron Trim Tab |
Hello All.
Europa 914 Tri gear, Speed 125 kts in level flight, to keep the ball in the centre
i have to hold on left rudder.
The Rudder has a fixed Trim Tab which servo,s the rudder to the left ( same as
holding left rudder on)
But to maintain the ball in the centre i have to hold on more left rudder on and
hold the stick to the right,
If i look out at my left Aileron i can see its about the thickness of the tip trailing
edge down.
So i need more lift on the left wing to maintain lateral level. ( How can i achieve
this ?)
1. If i put a fixed trim tab on the right aileron it will servo raise the aileron
and keep the wings level, but i will have constant adverse drag
maybe only a very small amount, Also will a fixed aileron tab effect the mass balance
of the ailerons, ( its only 4 x 1 1/2 of very thin alloy plate)
2. If i fix a Tab to the left flap outer edge, could i generate sufficient extra
lift to compensate, so the ailerons remain in line (neutral).

Alan,
What I did to correct the same problem was to put a stop in to keep the
port flap down sightly when fully retracted. Mine is a mono so a bit
different to the Tri gear to achieve. It certainly worked for me and had
not effect on performance.
For aileron trim to balance between one up and fully loaded I have a
small bungee cord from the lower part of the stick to the tunnel. I only
need this when one up as fully loaded my plane is balanced.

Craig, Karl and all,
Karl gave a good number of the pros and cons of 2-blade vs 3-blade.
As has been stated, drag is also to be taken into account, as well as
propulsion efficiency.
The main advantage of 3-blade props with small engines is reduced
diameter, for ground clearance or reduced tip speed (= noise and drag).
That's why 3 or more blades are used on airplane when noise reduction is
at a premium.
Apart from the above, there are few engineering reasons for adding more
blades on low power aircraft. (100 hp is not much for an aero engine).
Best regards,
