Dear Vansairforce members greetings from Tuscany Italy
After 3 years of intensive work finally my RV7 with one Lycoming O360A1a ,180 HP driving a constant speed prop and analog avionics had airborne on the 25th of March.
After the first flight of about 20 minuts little cruise and some touch and go were made. All went well.
The performance noted solo and half fuel are :
Take off distance about 100 meters,330 ft.
Climb rateo 2000 FT @ 100 kts
Economic cruise was 160 kts @ 2300 rpm,23 MAP.
The prop I have adopted is the Hartzell HC2YK upgrade with wood composite GTV24HY blades.
Company suggested 73” diameter.
Compared the original stock Hartzell the GT blades reduced weight of about 10 kg,20 pounds with very low inertia moment. Much appreciated on take off !!
Very smooth, expected dynamic balance by factory shortly.
See company link,
I’ll be more precise in performance after next flights.
Thanks Umberto and Vans for this fantastic aircraft.
