I was wondering if any of you building or flying the CH601 are using the EJ-22 engine from Subaru? I ask this because I have one from a Legacy year 1990. I would like to know if any one has experience with it and what modifycations there has to be done before instaling it in the plane.

I don't know about your 701 question but I can shed a little light on the new territory question. A lot of the remote portions of the NorthWest Territories was just too remote to be adequately represented so they created Nunavut. I think it is the largest partion of land of any territory or province in Canada but it is all north of 60 and VERY sparsly populated.

I took delivery of my kit in Sept 01 and although it was supposed to be the SP addition, many of the parts were not updated. Also the plans were third addition, ZAC provided 4th addition plans and parts upon request at no charge - they've always been great. Although I did initially recieve the heavy nosegear the firewall braces had to be updated. The bungee was obviously too thin for the upgraded firewall and when ZAC sent the new bungee it appeared to be 4 times thicker. once mounted and fully extended (no engine) it is loose and close to coming off. Is that what you're seeing? Chip Muldoon 701/912s doon47@aol.com ________________________________ Message 6 _____________________________________ Time: 08:37:11 AM PST US From: "Randy L.

Answer: A piece of thick "sheet" aluminum. It was cut from a rolled sheet, it was never extruded as a 3/16" x 4" "bar". There is a thickness where "sheet" turns into "plate" Although rectangles can be extruded to standard sizes (i.e. 1" x 2"), these same sizes are often "sawn" from plate of the appropriate thickness. This was the problem with building you own landing gear spring for the original 701 design, it required a 3/4 x 3 1/4 piece of 2024. While this is not a common extruded rectangle size, it is no problem to have it sawn from plate. If you were buying 2000 lbs. of them, they would be very inexpensive. When I asked for a quote through metal suppliers for 1 ea. with associated plate sawing charges, it was cheaper to buy the finished blank from ZA. And, don't get me started on the widely tossed around term: "billet".

This would lead one to beleive that the 30 isnt being used or is undesirable. Can any of you comment on whether the 30 is practical or not --I need to know whether to include this position on the flap actuator. If it is a safety problem (accidently going to 30) then Id prefer not too include it.

I am not satisfied with the way mine look. I used the hammer as suggested in the manual. The manual doesn't mention anything about a squeezer which I didn't know existed until the recent list discussion over the past week. One of the reference books I have talks about drilling out solid rivets, but they also mention that the heads have a dimple to help start the drill. I think this is for the larger solid steel rivets and not the small copper ones which don't have said dimple.

The dimple in a solid alum. rivet is a marking that means it's a structural rivet. A rivet without a dimple is a non-structural rivet (soft 1100 alum). The copper color is a cadmium coating, for corrosion protection. To remove a solid alum rivet: Center punch the rivet and use the same size drill bit as the rivet and drill just to the skin. Do not drill right through. It's almost certain you'll elongate the hole, then to the next larger size rivet . Set the same size diameter punch in the hole you drilled in the head of the rivet and break the head off. Then, use the punch to push the remaining rivet out. This will prevent the hole from getting any larger.

Thanks again. >Chuck Hagerty Hi Chuck, I used one 4 and one 8 foot sheet of 4 ft wide plywood, cut down on the sides to allow for a clamping lip, screwed into the beams. Then I used a 4 and 8 foot full width piece of MDF, placed so the butt joint were not on top of the plywood joint, and screwed that in place. Despite pounding on it and standing on it many times, it has stayed straight and level for over 2 years now. Over time, some drill-through holes have eaten away at some sections, so next time the table is clear, I may flip the MDF pieces over for a new surface. I don't think there was $8 difference between the plywood beams and 2x10s.

Using the same rivets, put together a couple of scraps. Then try this technique to get the feel for rivet removal before you go at your real project. Avoids damaging the real thing while learning this technique. Good Luck Ed Kramer wrote:--> Zenith-List message posted by: "Ed Kramer" Hap!

The tenth digit does not change until you get all the way to the next whole number. For example, If I have 14 pounds in the baggage compartment at arm +55.1 I have a moment arm of 10274 with a weight of 932# my CG is 10.97 but the GPS 196 gives me a CG of 10.0. If I add one pound to the baggage I have a real CG of 11.02 and the GPS 196 reports it as 11.0. If I increase the baggage weight to 36 pounds I have a real CG of 11.994 but the GPS 196 is still showing it as 11.0. I have sent two emails to Garmin but have not received a reply to either of them. Since we have a forward CG the tenth digit is important information. Any ideas on whether I have a properly functioning Weight and Balance function or how to get in contact with someone at Garmin that might answer their emails?

I can get in and out with or with out flaps, but in a no wind condition full flaps steepen the approach and shorten the ground roll. And since my strip is in the valley I have calm conditions most of the time I land with full flaps 95% of the time. It does take a alot of getting used to. With no power full flaps I hold 55 mph, this gives you a steep nose down pitch which is un-nerving and the flair is critical, because as soon as you flair your air speed drops fast. When you first start using flaps keep 500 extra rpms in till your mains hit and this makes the flair a little better. I flew about 70 hours befour I started using flaps,then it was practice practice. At about 120 hours I moved my batterie to the tail cone. This moved my empty CG to the center of the loading range, and my loaded CG to the aft 1/3 at gross I'm just inside the aft limet. For me this is where the plan flairs best, the noes does not want to fall on to the run way.

Thwing" Subject: Re: Zenith-List: alum bar? --> Zenith-List message posted by: "Randy L. Thwing" I stand corrected. AFTER I sent my message I looked further into the AL situation. Aluminum is rolled into sheets and plates, it is extruded into shapes, and it is rolled into common sections. Aluminum rolled "BARS" are available in 1\8" and 3\16" thickness. I checked two suppliers stock lists, and bars of this thickness were not available in any width beyond 2". I will take Mike's word that widths up to 12" are available, but I have not seen them offered anywhere as a stock item. I consulted "Machinery's Handbook" trying to determine at what thickness "sheet" becomes "plate". They have a chart labeled "Aluminum sheet and plate thickness tolerances" with thickness starting at .006" and ending at 6.00" with no distinction between sheet and plate. Another chart was labeled "Tolerances of aluminum sawn from plate" thickness on this chart begins at .250 and go up from there. I am paraphrasing the titles of the charts as I am at home and the reference is at work. Since the reference to plates begins at .250 thickness, I'm assuming any thickness of .250 and up is "plate", anything less than .250 is sheet. Also interesting is that when buying aluminum such as rounds or rectangles, you must specify whether you want "extruded" (higher cost) or "wrought" (rolled) as shapes are available made by both processes. The extruded shapes have more precise tolerances. Properly chagrined in Las Vegas, Randy L.
