Even with some resistance due to the primer, there is such a huge surface area that I don't think it is an issue with the currents we are talking about. I am no expert, so you may want to search the aeroelectric list to see what they have said about it.

Even though there is a lot of good conductor between the joints something close to complete circuit isolation could take place at the joints. If this happens there will be no ground connection at all for the remote circuits. The biggest problem (besides complete circuit failure) I would expect would be interference with radio clarity generated by the strobes. Fortunately, it is relatively easy to measure the impact of joint isolation. Just measure the resistance from one end of the plane to the other with a multimeter. I would be concerned with anything over 100 milliohms. If the resistance is large the solution would be to run separate ground wires from the remote devices to the battery or common ground point.

If you look at the attached picture, you can see where my problem is. I can't get the two holes in the 7F12-4 Gusset riveted. The problem is caused by the 15 degree angle in the 7F5-2SP Side Channel. I should have set these two rivets in the Gusset and tubes before I set it in place, but I didn't There's not enough room for my manual or air powered rivet guns to set the rivet flush. I tried grinding off the side of the nose on the rivet gun, but still can't get the head to set flush. Any ideas would be appreciated. I bought a cheap HF rivet gun with a swivel head thinking I might be able to wiggle around and get it to work.... Alas, all my wiggling has been for naught.

We were last done because we took lots of time. I still have the wodden shipping box, so freight would not be bad from the Tucson area to your home via Truck or if allowed UPS. If we agree on cost, it will include me boxing up the rudder and taking it to the shipping place for you. Freight cost and method will be included in selling cost. However, if you decide on ours, be sure to get insurance for "completed airplane parts" valued at $500.00 or so. Or have me purchase the insurance under you= r name so that you are the one who would get reimbursed. If I get the chance = I will check on freight today or Wednesday of next week. I work on Tuesday.

Its handling is a little twitchy but it is great fun to fly. If you are a low time pilot with nosewheel only experience I would keep away from the taildragger...Nothing wrong with the TD its just easier to get training in nosewheel irplanes these days and TD's can bite you as they require you to always be on the ball during landing.

The HDS and the Corvair are an excellent combination aircraft. Despite the passionate opinions on choice of tail dragger or trigear, I've flown the tri-gear for only 85 hours and find the ability to drive the aircraft over some rather rough material and getting the 601 in and out of the hangar easily are the best advantages over the tail dragger. I also feel the airframe is less disturbed by landings on less than great turf or gravel or concrete. Steering is definitely positive and directed as easily as the little red wagon. The HDS has a thicker wing than the XL, but the three piece construction lends itself to a really strong design. I believe the older gear design is a pain to install, but a better, lighter design than the solid Cessna configuration. If you need help with anything or advice, this Zenith group is the best. I built a 601HDS and really enjoyed the process of building from plans. You will too.

I've been lurking around here since January and have really learned a lot just by reading the forums every day. I'm a 52 (almost 53) year old electrical inspector who has had the flying bug since about 1970, but real life got in the way of doing anything about it. I started on this serious quest to get an aircraft and a ppl about 2 years ago (when it finally hit me that my kids were grown, gone and I didn't have to "pay" for them anymore). My brother in law is a commercial pilot working for LabCorp and has taken me up a few times, mostly to make sure my dream has not died. I have considered the XL and still am. I just like the looks of the slightly cantilevered wings on the HDS. I want to build a plane that is comfortable, has plenty of speed for cross country and economical to operate (hence, considering the Corvair conversion). The wing baggage lockers was one of the main reasons for considering the HDS over the XL, however, speed and handleing is of more importance. I have yet to begin flight training but have been around aircraft a good part of my life (Navy, VietNam vet working on flight deck of an aircraft carrier in catapults and arresting gear). I have many construction skills from being an electrician for over 28 years, so trying to build an aircraft and reading blueprints doesn't scare me. By the way, I won't need a sheet metal break to build my plane. I already have 3 heating and air shops offering me the use of their 8' commercial breaks just to see an aircraft built. Lol, lucky me. I've learned a lot here and hope to learn even more as my building progresses. Thanks to all.

I am impressed with your decision to scrap build a Zodiac. I opted to use the kit approach. That gets the folks at Zenith to do the legwork acquiring materials and parts and to use their large scale equipment and know-how to make the big parts that would be difficult for me to do. Their volume purchasing allows them to get better prices than I ever could buying smaller quantities, but of course they get paid for their efforts and make a profit too. I could have just bought the difficult parts from them, but I chose to let them do the whole kit. I also chose a Zodiac, but the XL seemed a better choice to me than the HDS. It is a newer design with more performance and it is larger. I understand it is a lot more stable in flight than the HDS too, but I am not sure of that. It is the performance that was the deciding factor for me. I don't see any reason to use conventional landing gear unless your heart is set on that. Tricycle gear is much easier to handle on the ground. Tail draggers were never really meant to handle cross winds or paved runways, but they can do both when an excellent pilot is at the controls. Insurance for tail draggers costs more and the companies tend to require long checkouts before they will cover you at all. This is all because ground loop accidents are very common with tail draggers. They are not particularly dangerous to the occupants, but tend to bend the airplanes pretty badly. There is a small penalty in cruise speed paid for the nose gear in tricycle configuration. I don't think this one or two miles per hour is worth the risks and difficulties of handling conventional gear. I have never seen any performance information on the Corvair engines, but I suspect they don't do all that well. Their real benefit seems to be low cost rather than high performance or reliability. If you are looking for a minimum cost to reach your first flight then the Corvair may be your best choice. If it is performance you are after and price is not such a big deal then I suggest you look into the Jabiru 3300. Good luck in your project. I am sure you will find it rewarding.
