I have been flying a Phaeton II for a couple of seasons know. I have an OS .61 sf for power and I had Aero glass make me a fiber glass cowl for it. The only change I made is I added solder lugs and hard wood points in the wings to bolt the interplane struts to the wings. This because every Phaeton I have seen has holes in the covering where the interplane struts have so much movement they poke many holes in the covering.
