Forward CG was done with full fuel and pilot (pilot full too, I just had lunch). Aft CG was done with full fuel, passenger and pilot. The 601 has generous range of CG as demonstrated in my query. I suppose I could put the battery midway of the two locations but I am not sure that would be optimum. Will check with Zac before I make a final decision. Thanks, John Do not archive ________________________________ Message 2 _____________________________________ Time: 02:18:36 AM PST US From: Paul Mulwitz Subject: Re: Zenith-List: Battery location --> Zenith-List message posted by: Paul Mulwitz Hi John, I don't know the best answer, but I might know the best question. What will make the plane fly best? The further forward you put the battery, the further forward the final CG will be. This would tend to increase pitch stability as well as reducing weight due to lack of battery cable required. If this is within the design CG envelope then it might be the best choice. On the other hand, a forward CG means elevator trim in the up direction to counteract the tendency to drop the nose. This extra nose-up trim may increase cruise flight drag and reduce cruise speed a bit. Is it better to have good pitch stability or higher cruise speed? That is where I get stuck.

Because the fuel tanks are ahead of the CG, the CG will move farther aft as you burn off fuel. To do a proper aft CG calculation you start with max gross weight with whatever fuel load you would plan on taking off with then delete most of the fuel to find the most aft CG condition you might have on landing. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru. on 12/20/05 11:36 PM, John anderson at ande437@bellsouth.net wrote: > --> Zenith-List message posted by: "John anderson" > > Hi Paul, > Yes.

Seems like I read a story about some Lady builder that used one of his engines in a plane she built/ rebuilt ? so modified and was greatly pleased. -----Original Message----- From: brucelee@mn.rr.com Subject: Re: RE: Zenith-List: Corvair crank --> Zenith-List message posted by: brucelee@mn.rr.com I've promised to keep my posts noninflammatory whenever possible but, am I missing somthing? Why don't more builders use the o-200 Continental? Yes, it costs somewhat more than a Corvair, but it's usually cheaper than a Lycoming. It's a "real airplane engine", it has redundant ignition, you can have a lightweight alternator without worrying about a belt, and by changing the cam and adding tuned exhaust, you can easily surpass 110hp. To me, it just seems like a natural fit for the 601XL.

None of the above is "politically correct" in some quarters, but since I don't subscribe to the Bleeding Heart Journal hopefully most on the List will accept the greeting from one who is not amongst the "enlightened". U.S. builders should turn to face Okla-Ho-Ho-Homa City, kneel and say, "Thank You" for the opportunity to enjoy our hobby. Might want to include Oshkosh, too. Its been a fun year......thanks to all for various tidbits that added to the experience. Many of you have excellent web sites with good photos. These have been a real help in some of those areas where I couldn't see the forest for all the trees. As for "lively discussion"........I've been in some establishments that sell liquid refreshments, where, if you didn't have a gun, they'd issue you one in case your mouth overloaded your rear. This List hasn't ever gone that far but it has occasionally been spirited. Keep up the good work. Merry Christmas everybody!

The drawing shows them all on the inside of the flanges (pointing inboard) and it shows the wing locker cross-piece attaching to (or near?) the third stiffener. 6-WLO-1 shows the cross piece attaching to the middle stiffener and you can't really tell which side the stiffeners are on. So the simple question is how do each of the three stiffeners go on RR#4? Second: 6-W-00 shows RR#5 as a left (for a right wing). This means the flanges are also pointing inboard - into the wing locker. That seems odd to me, though probably inconsequential. I spoke with Chris at the factory and he implied it really didn't matter - at some point it has been both ways as the drawings progressed. So, how did you do it? Do you have one side of the baggage locker with the flanges pointing away from the locker and one pointing into the locker? Are there any reasons that I may see later down the line that would influence me one way or the other?

If you are planning on building wing lockers (either now or in the future) I suggest you build your wing according to 6-W-0 rather than 6-W-00. If you build the wing with RR-4 facing inward and RR-5 facing outward (as shown on 6-W-0) then the rear panel for the wing locker will need to be 498 mm in length as supplied when you order the option from ZAC. If you are foolish like me and build it according to 6-W-00 then the rear panel needs to be 518 mm in length. When I built the stiffeners and panel support for RR-4 I put the three stiffeners in the inboard side (same direction as the flanges) and an additional "L" bracket on the outboard side for the baggage locker rear panel. I found it easiest if I used the same rivets and therefore the same location for the inboard and outboard "L" brackets.
