Do yourself a favor now, and at least ditch the stock retract in the nose. Mine got sloppy immediately. Here's what happens. The side frames are probably made out of some soft aluminum like 6061. That, in combination with the skinny web above the pin results in a really weak spot (Green line). The Robart's design and material choice is FAR better.
I switched out the nose retract for the 555, and it was perfect. Eventually, like ~30 flights later, my mains got really sloppy too. The sloppy main gear aggravated a 'kangaroo hop' down the runway on landing, and it did a bunch of damage all over.
