However so far the performance is quite hitting the right marks....Initialy thinngs looked great, with the first flight getting 180-200mph off half throttle....However opening her up has only yielded 220-230mph, which from what i gather is somewhat off the mark for full bore straight and level ??? RPM is a tocuh over 2500 The engine is an IO-540-D4A5, which was a new build by Norvick, there wasn't a stock C4B5 available and an extra 10hp can't hurt. The prop is a Hartzel HC-M2YR-1BF/F8475D-4. The governer is by Mccauley, i don't have the model no. to hand, but i don't know if this is the weak link. Anyone use this engine/prop combination, if so whats you governer/set-up ? Any ideas ??? Thanks, Lee ________________________________ Message 2 _____________________________________ Time: 08:19:44 AM PST US From: Norman Younie Subject: Re: Rocket-List: Initial Poor Rocket Performance It sounds like your governor needs setting up. It should go to 2700 rpm for max hp. 2500 is 200rpm too slow.

John Harmon's brochure claims 230 mph cruise. I flew with him many years ago and that is exactly what we cruised at. We are talking Indicated airspeed which as you know will decrease with altitude.

I am an A&P-IA, 48 years in the business, own and operate Midsouthjet Corporation, a maintenance facility for turboprops and jets at GWO. Have built an RV 4 and Miget Mustang and restored numerous certified airplanes over the years. So much for the "bio" for now, just wanted you to know where I am coming from. My question for now is, Do you know of any builder that may still have a fuselage jig they might sell or otherwise dispose of? Sure would be nice not to have to go through that again. Thanks.
