Use a sawhorse or anything like that under the wing. The complexity will be to compress the bungees so you can remove the top plate and disassemble the lower gear box.

Slide two of the bolts through the holes in the lower gearbox, with the top end of the turnbuckles attached to each end. Then slide the other two bolts, with a plastic sleeve over ithem to protect the aluminum, through the gear forks, with the lower end of the turnbuckles attached. Then just tighten the turnbuckles to raise the gear. It takes two miinutes to put in place, and doesn't require disasssembling the wheel from the fork.

Like many of you, I have settled on one of the excellent Zenair designs as my first homebuilt project, but the question is WHICH ONE? I have boiled it down to either a 601HD or 601XL. As far as I can tell, the XL would be somewhat more complicated and expensive to build (tapered wing, electric flaps), the main advantages being a higher cruise speed and a slightly larger cockpit. Engine choices are more diverse with the HD since the XL is designed for 100-lb higher gross weight and 100-hp engines. Fuselage complexity appears equal. I like the XL wing tanks, but I can get that option on the HD. So, since I really don't care that much about and extra 10-15 mph cruise speed, and I want to build as much as I can from plans, I am leaning toward an HD with wing tanks-only. The main reason is that beautifully simple, fat, forgiving constant chord wing with hingeless ailerons. Fewer parts, fewer forming blocks, easier assembly. Am I crazy if I don't build the latest version? Thanks!

Something to consider: the main landing gear in the XL is much easier to build. Making forming blocks is fairly easy. Making a bunch of them is boring, but personally I think it is worth the trouble. The actual drawback that I see is the wing panels: on the XL they are 12 feet long, while the HD has 2 outboard panels and one centre section, each around 8'. This may be a factor, if you are tight for space.

This is my point: A landing gear has to colapse if the crash/landing is hard enough (over certain values (?)). The design idea of all landing gears is getting some G forces out of the plane to prevent the pilot to get severly hurt... No landing gear is designed to be undestructible, in the 701 case, just overbuilt enough to handle "rough" landing spots (up to certain point of course). The landing and aproach has to be planned always to prevent the plane to hit the strip hard, if the landing gear will not colapse, imagine how the plane could "bounce" back to the air, now in more uncontroled manner and then really crash the second time, maybe sideways, if power and corrective attitude is not applied... In the May 2003 Plane an Pilot (page 28) is an article from Mr Budd Davidson: "101 Secrets to Super Landings"... A must read for all of us, new and not so new pilots. Also you can read it in: http://www.airbum.com/articles.html#How A MUST web page for all of us! Great articles.

As I understand it, the company president was flying a hang glider in the late 1970's when he experienced a structural failure while in a thermal. As he was falling the 5 or 600 ft. to his impending death, all wrapped up in the remains of the glider he said he thought, " I'm a top ranked pilot,,I did nothing wrong,I'm about to die and all the knowledge and skills I have won't change it. If only I had one last chance to do something, anything" By some miracle he survived when the cables and dacron of the glider slowed his descent as he crashed through some tall trees. Badly injured but alive. He still loved hang gliding and wanted to continue flying so he developed a hand deployed chute for hang gliders which have become standard equipment today. As hang gliders morphed into ultralights in the 1980's the ballistic rocket propelled chute was dev eloped for ultralights. You will see a BRS on probably 80-90% of the ultralights today. They have also been fitted on some Cessna 150's and the newest ones being tested are for even bigger aircraft, 165mph and 3600 lb. load. I was involved in hang gliding in the early years ,(1974-80) when we didn't have chutes. We were basically flying "lawn darts" off of mountains and I witnessed the death's of 3 good friends and 2 other friends that were seriously injured(paralyzed). I myself crashed/stalled into the trees twice with luckily no injuries. I ended up quitting hang gliding and starting a family before chutes became standard gear and later had 2 other friends who were saved by the chutes. According to the BRS advertisements they have 165 saves in ultralights. BRS doesn't make them for hang gliders anymore, somebody else does, I think. Just in case yoiu are wondering I have no connection with BRS and don't know anybody involved with them. I'm just building a 701SP and last Nov. 2003 made some inquiries to this list about installing a BRS in my 701. The Zenith builders website pages for the 701 has 3 pages of drawings for the installation of a BRS. However, it is for the old style"short" bag gage compartment and also really doesn't show what to do for covers for the bridles that run along the outside top of the fuselage. When I made an inquiry on this list last year I had several replies and one was from Chip Erwin who runs Czech Aircraft building all the Zenith aircraft.. I bought my BRS from him. He sent me 3 photos of the BRS installation they do in their 701SP with the long baggage compartment and also sent a nice cad drawing of the complete installation. He includes the complete installation kit along with the chute which has all the preformed covers,mounts,bolts,washers,rivits,etc.The chute is the softpak which is different from the Zenith drawings which show the cannister model. The model number/weight rating is 1050 with I believe up to 145mph opening. The chute is mounted on the back wall of the baggage compartment . As I am just now joining the cabin to the rear fuselage on my 701 kit I have no idea how this will affect the CG but thats the way they mount it at Czech so it must work out someway. If anybody is interested in the installation photos,plans, etc. on my 701 I can send them to you or maybe see if Jon Croke wants to post them on his 701 site. I debated with myself on whether or not to install a BRS on my 701. The debate was about money and NOT about the risk of flying or whether or not I should have one. I just barely scraped together enough money to buy the 701 kit but I did get the BRS and I have no idea when or IF I might be able to come up with enough money to buy the FWF kit and engine. That's how i got into hang gliding.... a yearning to fly but no money to pay the $25 hr. cost to take flying lessons back then. Just $650 worth of tubes, cables,bolts and dacron and a rock cliff on the top of Lookout Mtn. in Tenn. and I was flying!!! The 2 fellows who died in the 801 crash in California last year might have been saved had they had a BRS. I think I recall hearing that the plane broke apart over a 2 mile long area caused by the failure of the horiz. stab mount??The odds are I will never need to deploy the BRS in my 701 and the odds are I will never be struck by lightening or win the lottery but somebody does almost every week and if it is ever me I want that one "last chance to do SOMETHING". Regards and Merry Christmas and Happy Holidays to Everyone and please excuse the rambling post.

One thing that hasn't been mentioned if you're plans building and I think something to consider, you can buy any part from Zenith. What's wrong with buying the wing spar and ribs already fabricated. You will still save a ton of money. This is what makes Zenith a good choice, you can make it as easy as you want. On the other hand, if you're happy with HD performance, have you considered the 701? I spoke with Danny at Skyshops and their getting 100mph with the 912S at 4950 rpm. This might be easier to plans build since it has the shape of a brick ;-) and if I had more time .... I had the XL on order and had second thoughts. The 701 was always my first choice, but I wanted to use the Corvair and in my opinion it's a bit too heavy. You will notice that I was fishing for advice recently on the list and I caught plenty of good stuff :-) I called the factory today and changed my order to the 701 because it will suit my style of flying, low and slow with great visibility. Happy Trails!

I will do the usual Zinc Chromate on the out-of-sight mating parts, i.e. inside of doubler, etc. I would like to keep the aluminum look for a while, as I may not paint most of the plane right away (if ever), and wheel pants will only be added much later. I'm thinking of using the clear Alodine treatment for protection, but I'm not sure that's effective. Does anyone know if the Alodine protects by itself, or is it only effective as a pre treatment for painting?

I will do the usual Zinc Chromate on the out-of-sight mating parts, i.e. inside of doubler, etc. I would like to keep the aluminum look for a while, as I may not paint most of the plane right away (if ever), and wheel pants will only be added much later. I'm thinking of using the clear Alodine treatment for protection, but I'm not sure that's effective. Does anyone know if the Alodine protects by itself, or is it only effective as a pre treatment for painting? Thanks, Kent Most of the big airframe chunks done. ________________________________ Message 19 ____________________________________ Time: 02:40:19 PM PST US DomainKey-Signature: a=rsa-sha1; q=dns; c=nofws; s=s1024; d=yahoo.com; b=orYyDGeW2pbCboRUxSlxtsLRGiigJPuUShs1iNl/es8YAXLLBTeIrHuRSk6n6hhpQWZ7oWkAjd0aE1pGvzOMrK+cfJ93/nYKYbADfyuwPlvke/FSxpabuBwXJruAJ2XZA7lzaqkgPhEE1fvXIOUrz5VbFO1VJUH+d3S05YGtTsk= ; From: Michel Therrien Subject: RE: Zenith-List: Subaru ICM failure? and ignition performance --> Zenith-List message posted by: Michel Therrien I tried to find this Summit meter for $30... could'nt... can you provide the part number?

See Ya, Larry N1345L Couple of years ago I spoke with a 701 builder at Mexico, who had suffered a hard NW landing. A 5/16 bolt for the NW axle broke. His idea of a fix for that was to replace the axle with a bolt all the way thru the NW bracket. Bolt same dia as the axle. Wonder if anyone has experience or ideas for strengthening the nose landing gear? One thing I have seen is the use of a steel plate, tow bar plate, under the alum bracket assembly, and bolted to the strut bottom plate. Also, the use of six 1/4 in bolts to bolt the NW aluminum bracket assy to the strut. That is, two additional bolts, added to the four shown in plans. Middle, front & rear. This looks like a useful area for discussion. Ideas please.

I'm well aware of the other points you made. I may need a heavier landing gear because my engine weight is more than the stock gear was designed for. And, I know that that plane had a heavier engine also. The type of landing he made, may answer my question. So rather than replace everything I was wondering if I could press a smaller tube inside the standard gear and serve the same purpose.

I just received my electric trim tab kit for my HD today from ZAC and proceeded to install it. Everything went fine and now I'm in the process of setting the travel and deflection. I installed the trim tab on my right wing since I think it will be move effective to counter the "heavy" left wing while being flown solo (better leverage). So my question is, right now the trim motor at the back travel limit has the trim tab in a neutral position in line with the bottom of the aileron (meaning no affect on aileron dynamics). At full travel I get a fair bit of trim deflection in the down position which is correct to move the aileron up and push the right wing down. How important is it that I get some "up" deflection of the trim tab to push the aileron down and the right wing up? Anyone have occasion for the left wing being down a slight bit? I had to trim the Ray Allen plastic horn to get the inside the horn to fit but if I determine by responses that I need to have an equal amount of travel in the up position I will have to fabricate a new curved horn to give me the travel required in the limited space of an HD trim system.

The weight and balance report you send the FAA must include the most forward CG case and the most rearward CG case. The most forward CG case for the XL is full fuel and pilot and no other payload. The most rearward CG will be pilot, passenger, baggage and the minimum amount of fuel you would ever expect to have at the end of a flight. In my airplane, neither case occurred at full gross weight. Most airplanes are designed to fly with either a full load of fuel or all seats full but not both. So max gross weight may include full seats, baggage and something less than full fuel tanks or it may include full fuel and a lighter load of passengers and baggage. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru.

When I have a passenger my size or smaller and balanced fuel tanks my aileron trim is close to neutral. When I fly alone I usually do pick up the left wing with trim. Sometimes the trim tab is down on the left aileron - big passenger and more fuel on the right side. My trim tab moves the same distance each direction. I think that it is best to center it - symmetry you know..... I had a heavy left wing. I fixed it by squeezing the right wing trailing edge. Because this minor change had such an impact I think that it would be hard to have an airplane that was in perfect trim the first time it flew. I effectively countered the heavy left wing, on that first flight, by using right aileron. I didn't think about using rudder, if I did I would have.
