It will be interesting to see if Sonex comes up with a firewall forward kit to use the Aero Conversions 2180 in the Sonerai maybe a cowling redesign to use their hub and and a new design on the front of the fuselage that clears the starter and possibly a spinner similar to the Sonex. Time will tell but I have high hopes that that this will be a good thing. I am sure John has some things up his sleeve that he has been thinking about trying over the years . TJ
