I seem to recollect a posting showing suggestions for a dolly which would hold a mono upright whilst de-rigging and then allow movement of the a/c.

I am  considering moving the ship into the garage for the bad weather months this winter. This will only be possible off the trailer and minus the prop and the rudder.

Simple suggestions will be most welcome.

Mike...Steve Hagar designed a beaut...I suspect he would send you some CAD dwgs for dimensions etc. as he did for me.

Mike, I have a great dolly which was manufactured by Roger 

Targett, which holds my plane perfectly for rigging and 

being height adjustable, it also allows the U/C to be 

raised & lowered for work on Tyres, Brakes & wheel arch. 

It depends on a strong fibreglass splash moulding of the 

lower fuselage from the firewall back a couple of feet 

with a cut out for the U/C, which is lined with soft 

material for the fus to sit in, and it is through bolted 

to the fuselage to nuts bonded into the hull. The whole 

thing fixes into the covered trailer for transport. I will 

send you pictures in the next 2/7. Roger did this as a one 

off but it would be within the competence of many, 

possibly most builders to make something similar.

Regards, David Joyce, G-XSDJ

Thanks Fred. Is that your interpretation of Steve’s design, ie without welding?

Thank you Steve. That has given me something to think about - just a bit worried about the welding but maybe I can bolt it up.

Mike...my interpretation for sure...I separated the dolly wheels a bit more for added stability...those slotted framing extrusions are kinda spendy so I substituted 3 x 3 sq tubing where possible, but fully welded per Steve's design...I fitted and cleco'ed everything then gave it to my welder who charged me $30. for 15 minutes work max.

For Michel and anyone else interested,  I attach a brief 

description of my dolly which has proved very satisfactory 

for plane handling, working on the undercarriage and for 

transport in a covered trailer. It was made originally for 

another mono, but when he converted to a trike I bought 

the trailer and fitted captive nuts to my plane by simply 

drilling through the existing bolt holes in the dolly and 

then bonding in nuts and largish washers on the inside of 

the fuselage together with a bit of appropriate local 

strengthening. As far as I can see none of the 

measurements are particularly critical although of course 

the fibreglass bearing surfaces need to be nicely matched 

to the fuselage. Having said that you do need to design it 

so that you can get it underneath the plane in its normal 

wings on position. Can send further views + measurements 

if anyone is keen to pursue it.

That's very interesting and kind of you to share.  Was it you who also mentioned they have an LAA approved 100 Ltr ferry tank and, if so, are you able to share the details of that Mod?



Kind regards

Richard CC

Richard, Yes. photo of the build sage attached. 

Essentially I made an outline pattern by cutting a 

longitudinal midline (of the seat well) partition and two 

transverse partitions, analogous to the partitions you can 

see in the tank. I sellotaped them together to insure that 

I could get the resultant solid shape in and out. The 

 base is a 5 layer bid splash moulding of the seat pan 

with the edges turned up vertically for a couple of 

inches. The sides are of high quality foam with 3 layers 

bid outside and 2 inside all the joints are made with flox 

going about 1cm into each panel edge then covered with 

tapes of same nos of bid in and out. There is a small sump 

at the back of the system, and also a recess for the 

starboard spar pin. All partitions are vented at their 

tops and bottoms. It works with a syphoning system that I 

bought from Europa - designed for their long range tank. 

It is retained by the seat belts with  extra multiple loop 

straps around the top and front, calculated to resist 10g 

in any direction.

Flow rates demonstrated to exceed max 914 consumption. I 

had previously by the way left a bit of bid/foam/bid panel 

in avgas & mogas for some weeks without being able to 

detect any sort of degradation.

           Regards, David

Issue 40 page 2 of Europa Flyer shows a photo of the mono support used at Flightcrafters.  We have a similar support except the support arms point to the rear of the aircraft not the front.  It is quite simple and easy to use.

Hi David 

 	"Can send further views + measurements if anyone is keen to pursue it." 

 	I am interested, any information you can provide would be greatly appreciated. 

 	What size screws are you using that screw into the fuse? You by chance have a pic of your reinforced and mounted nut? 

 	Do you see any advantage to using castors that you can lock rigid, or unlock and let them castor? 

 	Do you see any advantage using wheels that have brakes? 

 	Thx. 

 	Sincerely 

 	Ron Parigoris

How do you fix your support to the u/c leg Jim?

Do you bolt it through or clamp it somehow?

For those you expressed an interest I attach some key 

dimensions. The fixing wing bolts are currently many miles 

away in the trailer but I think they are either 6mm or 

8mm. Incidentally the track of the dolly wheels is 

sufficiently wide that you can take one wing off without 

needing to  support the other one.

Mike,



We just clamp it to the swing arm.  We do have a couple of angles welded to the cross bar to locate the dolly on the swing arm.  Sorry we don't have any photos of it installed.

I have been following this thread quite closely as i am building a mono and one day it will need to stand on its own. I have seen many different solution's to the problem but yours David or Roger's is the best iv seen as not only does it hold the fuselage upright it can be raised to replace pads ect AND it can be used to hold the fuselage in transit AND hold it while rigging!! I was that taken with it that last evening i started to make my own my taking splash mouldings of the fuselage, so as was said before thanks for sharing David. Thanks Frank
