My only caution is to assure the fuel has no alcohol in it. Ellison will not state it is OK to use auto fuel but with the before mentioned cautions there will be no problems. Hope this helps.

I hung my elevators on the HS during construction and noticed that they dropped to the bottom due to the weight of my servo motor. To counter this, I had to form and attach an additional lead counterweight. I hear that Vans has since changed either the amount of lead or the instructions for cutting the lead, I'm not sure which. I intentionally left slightly more weight than needed, so that the elevator now trailed slightly high. After final paint, it falls roughly level. If I needed to remove more lead, I could simply drill into the weights, but close enough is close enough. She flies like a dream! ________________________________ Message 4 _____________________________________ Time: 11:42:50 AM PST US From: "Mike Duiven" Subject: Re: RV9-List: Elevator Adjustments and Related Accuracy Requirements --> RV9-List message posted by: "Mike Duiven" Speaking of precision, what have people found out about: Accuracy to which the Horizontal Stabilizer Tips should be of fixed distance from point on firewall - I have it down to 1/16". Is this good enough? Accuracy to which the Horizontal Stabilizer should be aligned to level - I have it down to 0.2 degrees. Is this ok or should I add shims to get it closer to 0 degrees? Accuracy to which Right and Left Elevators should be aligned to each other - I have them down to 0.6 degrees and am worried about potential roll torque at high speeds? If anyone has any sage advice here please let me know. Mike Duiven N711ED (Reserved) Relative to issues of balabce - I had to add some mass to weights to account for electric trim motor. I have left them a bit heavy and will drill them out if and when it is needed. Better to be a little heavy and take material away than to have to add material later. emduiven@chaffee.net or emduiven@eaa1161.org ----- Original Message ----- From: "steve dwyer" Subject: RV9-List: Elevator Adjustments > --> RV9-List message posted by: "steve dwyer" > > I'm not clear on what balanced means when it comes to setting up the elevators.

Van makes clear his concern for flutter in the performance testing of the manual. Has anyone experienced problems here and to what degree of detail should we strive for? I recall reading somewhere we are not trying to balance the system only prevent flutter.??? Also if anyone has drilled the counter weights to lighten it did you drill a series of holes along the centerline or just one? > > Steve Dwyer 90219 Painting completed > > ________________________________ Message 5 _____________________________________ Time: 05:42:11 PM PST US From: "fcs@jlc.net" Subject: Re: RV9-List: Elevator Adjustments and Related Accuracy Requirements PRIORITY_NO_NAME --> RV9-List message posted by: "fcs@jlc.net" My advice would be to keep building and stop worrying about precision. It sounds like you're well inside the envelope where the wings stay with the craft. ________________________________ Message 6 _____________________________________ Time: 06:15:21 PM PST US From: robert watson Subject: Re: RV9-List: Elevator Adjustments --> RV9-List message posted by: robert watson Balence each half sep.this way you can get better balence in case you have a trime servo or more paint on one side then the other.multi.holes along leading edge of counter weights worked best for me.less on servo side. bolt together after balenceing very smooth.you are balenceing the surface not the linkage just like rudder and ailerons. -----Original Message----- From: steve dwyer Subject: RV9-List: Elevator Adjustments --> RV9-List message posted by: "steve dwyer" I'm not clear on what balanced means when it comes to setting up the elevators.
