I think that the main reason that there are several versions, is because of the amount of steering as you tilt. I think that outside other things, the main thing is to find the balance in tilting and steering.Now you and Emeil have spent a year extolling the flaws of tilt steer , so I shall keep well away...
Also DannyC of this parish has a aversion to twisting chain so another black mark against it.
Impressive turning circle , although he is just sat on 2 elastomer's as I am ?
Had plans for this for a while 26 x 26 tilting delta always slightly tempted by it's simplicity ?
Good selection of pictures here :- Triflex
Even a video !
Perhaps tempt DannyC might work well with 24" wheels and SA brakes on the back ?
The main problem is the videos imply there are 6 versions ! so obviously ironing out some flaws me thinks !
