Gents,
I’ve often had concerns about the stability of the mono wheel fuselage when it rides along the road on its “bespoke” trailer...(couldn’t resist the opportunity to use this very British utterance).
When my mind imagines the moment arms and the mass, stabilized solely by the capturing of the sides of the LG02 retraction arm within the sides of the tilt-up ramp, I fear that the fuselage tipping over, contacting the wings or worse, is just a heartbeat away.
I have similar concerns about the stability of the fuselage while on the trailer during the attaching and removal of the wings…an operation I’ve yet to attempt…but the amount of the forces in play that I’ve experienced when attaching the wings when the fuselage sits on a cradle in the shop gives me pause.
Can I hear from those w/ actual experience as to whether or not my fears are unfounded?…or is the fuselage stabilized by some additional means by which I am unaware?

When mine was a Mono i used to put first wing on and support it while attaching second wing.

Fred,
I've made two hooks out of flat steel, with some padding glued to the inside of them, that fit into the openings for the spars. They are then attached to the trailer frame below with the usual ratchet set-up. For placing the aircraft on the trailer both wings should remain attached for better balance. You will need somebody to hold the wings level while you winch the aircraft onto the trailer and adjust and attach the folding up ramp. This will hold the aircraft , while you support the left wing , raise the wing cradles etc.. , but , as you have already determined, is not sufficient for road travel. After removing and loading the wings it becomes a little more awkward to hook up the the fuselage to the trailer frame, but it must be done. Since the fuselage is facing tail forward, it helps to fabricate a padded pair of scissors to keep the rudder from being exposed to some vicious side-loads . Do not put the elevators on the trailer! I always carry them in the car.
Hope this helps.
Cheers , Peter

Hi Fred,
I have placed a rubber block, shaped to form where it contacts the fuselage and glued to the inside of the wing holder arm that retracts for de rigging/rigging.
Once the fuselage is on the trailer, retract the wing holder arms either side and the rubber blocks hold the fuselage upright.
At the tail of the aircraft I use bungee cords around the tailwheel arm and trailer track to stop it jumping out of its track race which has happened once.
Otherwise it does travel well on the trailer. There are various other minor alterations you have to do due to Mods on the the Spars but all doable.
Cheers.

Tim, Peter, and David…thank you for confirming my sense that additional means to stabilise the fuselage on the Europa mono trailer is necessary, as well as the clear descriptions of how you’ve dealt with the issue.
Best,
Fred

Hi Fred,
I also use Peter Timm's idea of using hooks into the wing recesses and strapped down to the trailer. Other ideas are :-
- If I am moving the plane any distance, I remove the rudder. I find that even with a padded restraint, the rudder will want to zig and zag from side to side.
- I use a ratchet strap to hold the mainwheel down into the scoop. (This idea from Bud Yerly.)
Cheers, John
