Friday I flew to Llano (70 miles) to pick up some barbecue for the wife an= d myself.  Take off was at 900' field elevation and I climbed at full= throttle to 7,500'.  I used 7500' as the test altitude because Bill= Eslick's RV-6 flight test data sent to the list on 3/10/10 had graphs for= 7500'.

Climbed @  110 kts. indicated air speed  - Full throttle climb= to 7500"
OAT 70 deg. at takeoff
Initial climb rate was 1800 - 1900 fpm
( I get ~ 2400 fpm with only 21 gallons in the tanks)

@ 4500" the climb rate was ~ 1400 fpm
Water 188 F, Oil 200 F

@ 6000' the climb rate was ~ 1250 fpm
Water 188 F, Oil 203 F , OAT 60 F

@ 7500' climb rate was ~ 1000 fpm
