I think you're going to get spoiled (and addicted) by that big-engine mutant -4! Then you won't be able to go back to lower horsepower. :-) Chuck _____ [mailto:owner-rv4-list-server@matronics.com] On Behalf Of rob ray Sent: Sunday, July 16, 2006 10:01 PM Awesome Chuck, back in the day (1996) I gave a ride in my then 150 HP Sterba wood propped RV4 with no paint at a whopping 935 lbs soaking wet to a 250 pounder who helped me. I put my tool box on the pedestal bewteen my legs, full fuel and a long runway at Newport News VA but all was for naught. The Bandit flew fine with just a little pitch sensitivity and forward trim...Now that I am flying the Harmon Rocket, all bets are off...bring on the big dudes!!! (and girls...ha!)

First of all, I was pleased that my empty weight turned out almost in the middle of the range I was hoping for (950-975). It ended up at 967 lbs with the empty CG at 68.9" AOD on an O-320-powered -4. Other weight savings items I utilized were the Odyssey PC625 (13.2 lbs.) battery (it cranks the Sky Tec just fine) laying on its side in the left floor compartment ahead of the wing spar, Sky Tec starter, B&C 40A alternator with Nuckoll's Z-1 electrical system and the Ellison EFS-4 throttle body injector. I even have a full vacuum gyro panel but not set up for IFR with just a GPS/COMM and transponder only in the center stack under the main panel. What was interesting was the full-tank fuel burn scenario of me at 225 and a 120-lb. rear passenger (no baggage) with the CG moving aft only 4/10's of an inch over the burn down to 5 gallons total left in the tanks. Even the worst overloaded case of myself and a 245-lb. rear-seater had the CG a hair forward of the aft limit (77.4") with 5 gallons left. So it looks like the WW 151 will be a good match with this airframe. Now for first flight! :-) Chuck Borne RV-4, N353CB Vans S/N-4069 Waiting-for-FAA _____ See the all-new, redesigned Yahoo.com.
