    Subject: Leadweights too light?
    Hi! Thanks for the inputs regarding PVC-tube in the wings! We're done with the empennage now and both elevators are AFT heavy. On the right one, we adjusted it per plans, but we had to bolt the removed leadpiece back onto the counterweight to get the elevator closer to neutral. On the left one, we didn't do anything to the counterweight. I guess we can solve the problem by adding lead in the forward part of the fiberglass tips before installing them. Have anyone else encountered this? The only reason I can think of is that we maybe put too much tanksealer in the aft part of the stiffners?? (But I don't think we overdid it....) Best regards Alf Olav Frog / Norway

    Subject: Elevator trim too sesitive?
    Hi! I've heard some rumours that the electric elevator trim is very sensitive? A way to solve it is to slow down the trim motor maybe? We've installed the combined trimtab-horn on my left elevator, the one that followed with the emp kit. (The one that can be used both for manual and elec trim. One just trim off the part one's not using) My plan is to fly a few rides with the trim rod attached to both the attachment points in turn and THEN trim off the one I like the least. What does all of you aviators with flying RV's think? Is the trim too sensitive? Best regards Alf Olav Frog

    Subject: Re: Elevator trim too sesitive?
    --> RV7-List message posted by: "RAS" <deruiteraircraftservices@btinternet.com> Using the tab for the manual trim isn't going to resolve a potentially fast running trim motor. The matronic governor will. Theses governors can also be used if you wish to operate two seperate bottons for the electric trim, as in one on each stick for example. The governor is ground adjustable by means of a screw. It is not recommended to do this in flight. ----- Original Message ----- From: "Alf Olav Frog" <alfolavf@online.no> Sent: Monday, February 13, 2006 6:55 PM Subject: RV7-List: Elevator trim too sesitive? > Hi! > > I've heard some rumours that the electric elevator trim is very sensitive? > > A way to solve it is to slow down the trim motor maybe? > > We've installed the combined trimtab-horn on my left elevator, the one > that followed with the emp kit.

    --> RV7-List message posted by: "Bill Schlatterer" <billschlatterer@sbcglobal.net> I think the issue is too sensitive at what airspeed? Some have said it's too slow with the flaps out (low airspeed) and too fast/sensitive at cruise. Rocket Boy products and Matronics both make two speed relays to allow you to cover both ends of the spectrum. High speed when flaps are deployed and lower speed at cruise. They also cover, Pilot Co-Pilot override and runaway trim issues. http://www.f1-rocketboy.com/tcm.html Bill S 7a Wiring -----Original Message----- From: owner-rv7-list-server@matronics.com [mailto:owner-rv7-list-server@matronics.com] On Behalf Of Alf Olav Frog Sent: Monday, February 13, 2006 12:56 PM Subject: RV7-List: Elevator trim too sesitive?

Do you know of people who are flying this system, could you forward me their names so that I could get their opinions. The alternative is Chelton, but I think that is just tooooo expensive for an RV7. Thanks

I'm sure he can comment on it, although I don't think he has much flight time on it yet. I know there are lots of others flying with it, so you may want to post to Doug's VAF Forums (http://www.vansairforce.net and click Forums). What I've seen of the GRT engine monitor, I don't like. And the EFIS, while it has a lot of functionality, has a pretty cheeseball screen. Paying thousands and thousands of dollars for something like that didn't appeal to me, personally. Everybody has an opinion! I obviously do! ;-) As far as Chelton goes, I don't understand why people put the megabucks into those systems. Hangar queens with fancy EFIS systems and they never or rarely travel. And they surely aren't pounding the IFR hours onto the plane. Ok, I'm generalizing, but still. For a predominantly VFR airplane, why the heck do you need all that crap? Another $10,000 to spare sure buys an awful lot of avgas, tiedown fees, hotels, restaurants, rental cars, etc. IMHO: Build your plane to be simple, functional, reliable, and SAFE.
