| Subject: | Re: SV: SV: Re: Some Trigear dimensions |
I have been watching these discussions with interest and you may wish to
consider an alternative approach to winching and safe towing of your
trigear.
I have had my trailer for 6 years or so and been towing the aircraft
over some fairly long distances (including 'rescuing' a trigear from
Shoreham to Nottingham).
I have a winch in the nose of the trailer and use a modified nosewheel
through bolt/axle which is threaded both ends (the modification was
carried out by Bud in Florida) - I can then attach the winch to the axle
on both sides using ring nuts purchased from any Yachting Chandler.
These then serve two purposes - first to winch the aircraft into the
closed trailer and secondly using bottle bolts to tie the nose wheel to
the trailer floor for towing (ensuring no significant movement in the
nosewheel on the move).
For the main wheels, I considered using a dummy spar tied at each end to
the trailer floor but in the end decided against that as the weight of
the aircraft jumping whilst towing could rip the floor out. Accordingly
I have a tie down bolt in the tail to which I attach two bungy cords to
the floor at the rear of the trailer. Whilst this allows some flexing
the movement of the tail is damped.
As far as chocking the main wheels I have a wooden chock front of the
tyres (bolted to the floor) and a chock that drops behind the main
wheels to lock them in place.
Realising that a picture tells a thousand words I will take some photos
later today to try to explain in more detail.
I hope this helps and if anyone wants further info please contact me. I
know that there are variations on this theme - Ian Rickard (G-IANI) has
a really nice trailer and whilst his mainwheels have a similar chocking
arrangement he has a bar under his tail to prevent the tail moving in
transit.

Le 07/02/2011 01:45, Karl Heindl a =E9crit :
Roland,
I installed stainless steel eye bolts in the fuselage right behind
the top of the legs. Installation is very simple, i.e. an 8mm hole which
also goes through the steel plate which is embedded in the layups. Then
in the baggage compartment I placed a large washer and locknut over the
bolt to make it very secure. Before winching the aircraft onto the
trailer I tie a rope or whatever between the two eyes (they are circular
not an open hook), and attach the winch cable to it. I have used it many
times without any sign of wear.
I also use them as additional tiedown points, as well as the wheels
without the spats.
I vaguely remember Neville suggesting something like that a long
time ago.
Cheers,
Karl

| Subject: | Ignition switch wiring |
Hi all,
Still investigating the kick back problem on my 912S, I have a question for electronic
engineers:
The Rotax schematic shows two separate AWG18 shielded wires from the ignition modules
to the ignition switches. On my aircraft, I have a twisted pair of wires,
probably smaller than AWG18, inside a single braided shielding. Is it possible
that this configuration cause interference between the two circuits so that
when ignition A is active and ignition B is grounded, ignition B may produce
some spark while I am cranking the engine?
Regards

| Subject: | trailer tie downs |
Further to my earlier email I have now photographed my tie downs and
these are attached.
2564 and 2562 show the nose wheel with the bolts on and off the nose
axle bolt.
2561 shows the winch, straps and tie down bottle screws ready in place.
2559 is the mainwheel chocking arrangement. Nothing ties down the main
wheels but the chocks hold the aircraft in place.
Hope this helps. If you need bigger resolutions on the photos let me
know.

| Subject: | trailer tie downs |
Interesting topic!
There is no one "right" solution here, and I have no desire to defend my
main wheel clamps solution. I will, however, add a few more thoughts:
Many tie-down solutions are OK for normal towing on a good or decent road.
But what happens if the trailer have a hard bounce, or even worse - what
happens if the trailer runs off the side of the road, or comes to an abrupt
stop because you have a collision, or somebody hits the trailer from behind
and jerks it forward? Will hard bumps/sudden stops introduce shock loads
onto the tie-down or the fixing points on the aircraft, and will the
arrangement hold the aircraft in place at odd angles?
I shall not be judge of which arrangement is best, only point to the
following regarding the main wheel clamps:
- The tie-downs are spread to the widest possible separation from
the centerline, i.e. best possible "capsizing" stability.
- The inflated main wheels transfer the tie-down loads, i.e.
reduces shock loads.
Regardless of arrangement, the tie-downs must be very well anchored to the
trailer - not only to the trailer deck of plywood or aluminum sheet, but to
the carrying structure of the trailer.
Regards,
Svein

I got my tail out and started going through the tailplane retention mod -
the one where you have to dig a hole in the underneath of the tailplane.
Do you need longer pip pins and if so what is the reference and where do I
get them from?

Remi,
That is very highly unlikely. The whole purpose of the twisted pair is to reduce
noise and interference.

I have done Mod 73 about 10 times so far. Of these only a couple of
builders decided to buy longer pins.
In general you do not need a longer pin if you carefully recess round the
hole.
Europa have longer pins if you want them.

Ian,
I have just been doing Mod 73. What struck me was that for this recess you have
to lap the bid onto the tailplane surface. If you then cover it with two more
plies, there is going to be a pretty substantial bump which will inevitably
influence the aerodynamics. It is also incredibly difficult to do without making
bubbles.
The top recess on the other hand only needs flox corners and can be trimmed flush.
Do you know why this is?

I was wondering....
I even bought some longer pins in anticipation of doing the mod from
McMaster...but yesterday I fitted them and pulled (by the body not the ring)
to test retention and out they came...not encouraging!
So I think I'll use the originals which don't come out when you pull them.
AT least mine don't.
Yours
Will

Jeroen
The simple answer is that the LAA wanted the best possible bond between the
bearing and the skin.
It is a difficult layup to do which is why I have done so many other peoples
aircraft. Make sure you make a reasonable radius from the "pit" onto the
skin.
The two layers of BID on the surface should only be about 0.6mm thick and
when flared in with some filler are not noticeable. I have not detected any
noticeable change in handling so I assume the aerodynamics are OK

Interesting and useful discussion in fact.
Karl, I'm also interested in a photo of the eye bolts you've mounted behind the
U/C-legs (as possible from the in- and outside).
My fellow Europa friends, there is another thing to solve for me: as I probably
mentioned already, I have to pick up my plane 1000 kilometres away from my homebase
in Perranporth. Within the next few weeks my trailer will become adapted
(has to be enhanced a little later I guess because I only have some dimensions
and drawings for the trailer company), which includes a wider track for the
main wheels. Since I can only modify the plane itself when I have it here, the
question is, where I can tie it down on the trailer provisional in addition
to the main-U/C (front wheel leg or fuselage between cabin and fin or both - again:
it has no tie down hook) to bring it here in one piece. Is it okay to allow
movement of the plane or do I have to tie it down very tight?
Any ideas most welcome.

As for the BUMP, if you use some sponge rubber (dish washing, seat bases
etc)
Cut some pieces about 10-15mm bigger than the hole all round, and another
piece
For the skin surface, wrap the foam in lunch wrap plastic and put it in the
hole
After you do your layup, and then the large skin piece over the hole, with
plastic again
And some heavy (4 or 5 kg) object, like a sand bag on top, will compress the
layups
Much the same as vacuum bagging would, it will generally push any excess
resin out past
The edge of the cloth, giving you a "glass like" very smooth compact layup.
I use this
Method for most of my glass work now where conformation into or onto a
complex shape would see a constant fight with the glass lifting creating
"bubbles" underneath. Four
Layers of bid done like this looks like about 1 layer thick
Hope this helps
