Ok found what I was after - you know when you have that gut feeling somewhere on the net is the idea you are looking for ?
From here :-
Solar tilting trike
So in my view it is :-
A wrapped version of iLean where both wheels are parallel and not staggered.
A more compact version of the white suspended tilter show above [ but without suspension ]
Could have suspension added if short tie rods changed for springs ?
So for me it is to narrow and has big wheels [ although they maybe in my future ?]
It is easy to see how such a compact mechanism could fit on the Python under the seat ?
The area between the cable tie on the main frame and the vertical pannier rack support previously housed the bottle cages and tent so both easily re-positioned , as can be seen the bulk of the luggage is housed just behind the axles and despite all the doom sayers have not cause any traction issues.
So ideally the unit wants to be narrower than the 30" the existing rear wheels are , but wide enough to get 2 panniers in side by side then one across the end and we are only 1 pannier and a tent short , if it tilts they can go on top as the c.g change should not be noticed....
Out with the Lego me thinks .......
