I shortened the front control stick so it would clear the instrument panel. Then I fitted the Infinity stick grip. I came ever so close to drilling the mounting hole 90° from the correct angle, but discovered the error just in time. You have to split the grip open to fit it over the stick, and it was a bit of a trick getting it back together again without having one of the switches fall out, but a few blue words scared everything into place. The various switches on the stick will operate the pitch and roll trim, trim and wing leveler disconnect, radio transmit, boost pump and starter. The last switch will be reserved for the smoke system, which may be installed during the mid-life update.
