Ed finalised the design and started the build. He also added an ‘Alignment Link’ so that the undercarriage tandem wheel strut can self-align when not under load. This is both scale (per the photo) below and very handy to align the tandem wheel strut prior to retraction.
Ed sending me teaser shots of the mains assembled prior to attachment of the wheels. Note the alignment link has double spring design for easy centering adjustment.
Photo from the internet showing the layout of the Mains. Note the alignment link on the front which has been replicated in the RCcrafter's design.
