The undercarriage is now braced.
Although you can't see it very well in the shot, there is a turnbuckle bracing line routed across the front of the axle fairing.
The end fittings are 0.4 mm nickel-silver tube with 0.5 mm aluminium nuts.
All that's left is to create the 'bungee' suspension and the undercarriage is done.
Then it's on to rigging the aircraft.
