A full-size paper template of the nutring is shipped with all orders for boots. It's easiest to install these boots before the wings are attached to the fuselage. However, it is possible to install the boots after wings are in place.

We now make an aileron boot that can be installed without going over the end of the pushrod tube. If you are already flying, this will make that much easier to install. there is a slight price increase for these boots reflected below in the pricing.
