The axle is flush with the bottom of the landing gear. This gives at least 10mm between the center of the bolt holes and the edge of the gear and maximum ground clearance. I filed off the corner of the landing gear to center the axle (with the caliper on it) - again this provides at least 10mm of metal. There are two (not close up) pictures on the ZAC web site. (follow the finishing link - I think.) To drill the holes I clamped the axle in place and slid the 1/4" OD 3/8"ID bushing that is used for the control stick into an axle hole. I then used an 8" 3/8" drill bit to drill a 3/8" hole straight through the gear. The bushing keeps the axle safe from the bit and helps align it properly. The 8" drill bit helped me to keep the hole parallel to the axle hole and gave me the clearance that I needed to drill. I then removed the axle and drilled the hole out to 1/4" (with a fresh bit) letting the drill bit slowly follow the pilot hole. Put a 1/4" bolt in the drilled hole - add extra washers to tighten it down to save the nut. Repeated for the other three holes. All of my 8 holes are aligned and the bolts slide easily in and out. The calipers can be removed with the axle bolted on. I am satisfied with the job. Joe Edwards N633Z standing on its own.

The resulting engine make about 100hp (or up to 300 if you really turbo boost/mod it), and weighs about 150lbs. I've been following the list on the ACRE site for awhile now, and one of the members has one working. The ACRE website is: http://home.earthlink.net/~rotaryeng/ and is run by Paul Lamar. Lot of good heads on the list, including a number of design engineers. Been thinking pretty hard about using a 13BT for the BD-4 I'm going to do next. Good luck..

After fighting oil temp issues for about a year, I finally bit the bullet and installed an oil cooler, which knocked the temps down by 40F. On a 96F day, I'm now getting a max oil temp of 218F, where before at 87F I was getting 240F oil temp. The o-200 only has one access point for an oil cooler, and the same point is also used for oil filter adapters. I had the filter already, which made it a tough decision, as I didn't want to remove it. However, I found an alternative. An auto sandwich adapter intended for Fords, has the same o-ring diameter and thread size as the Champion CH48108 filter used by the spin-on adapter. The sandwich adapter fits between the filter and the filter mount, extending the center threaded stud. The cooler oil lines tap into it through 3/8"FPT ports, and it includes a pressure bypass mechanism to bypass the cooler if it's plugged. Cost about $50 at summitracing.com. The cooler I used was a Positech experimental, smallest I could get, and the lines are custom made hydraulic hoses (local auto parts shop), 3/8" inside diam., at about $14 ea. Total invested, about $240. Anyway, just thought I would pass this on.

I started over three hundred hours ago by taxi testing slow, then to the speed of lifting the tail with full down elevator, and then increased from there. The wisdom of high speed taxi has been debated here, but I taxied mine up to 70 before getting airborne. Then I knew I could handle a landing. The plane is VERY solid in handling. If you have 100 or more H.P. you might want to apply power gently to avoid pulling to the side on take off roll. I apply mine gently up to about thirty and then let her have it. You should find the rudder very effective in cross wind landings. I wheel land 99% of the time, finding that simple, smooth and easier in the HDS. Take your time. I bet you will be pleased.

I thought I would post some results now that I have flown it a couple of times. I have a 2180 VW with a 1.6:1 PRSU and a 67" Powerfin ground adjustable prop. On the first and second flights, I was only able to get 75 mph at full throttle. Climb at takeoff seemed good for the first 100 feet, then dropped off to almost nothing. The engine was misfiring a bit on the first flight. I added the swirl plate in the manifold and flew it again the next day. The second flight resulted in very similar performance, without the misfiring. I think I have found the reason for the poor performance. Part of it was me and part of it was the prop. For a couple of days, I made few phone calls to Zenith, and Great Plains. It wasn't until I found a website that explained propeller physics that it finally hit me in the head as to what was happening. Basically, I had reached the max forward speed for that prop/pitch combination. When I did my first 2 flights, it climbed good for the first 100 ft or so, then it would barely climb at all. I finally realized that the reason for this was that I was trying to stay above 70mph. I didn't know what the stall speed was and didn't want to go any slower. Yesterday I added 1/2 degree of pitch to the prop and tried it again. This time, I allowed it to climb at 60 mph. I climbed all the way to 4200 ft @ 500-600 ft/min. Max level speed turned out to be 85 mph at about 3400 rpm (recommend cruise rpm). At that speed, I was able to trim and let go of the controls and still fly straight and level. I can't help but wonder what kind of climb I would have got at 55 or even 50 mph. I also wonder if a different prop will yield a better cruise speed. Maybe a 2 blade with more pitch. This kind of performance may be appealing to a 701 builder. Unfortunately, the front oil seal started leaking, so I'll have to deal with that before I do any more testing.

Don't know about you, but I fully expect my planes (a '49 Bonanza and a 701 yet to be started) to out last me and I'm 10 years younger than you. I plan to will the planes to my children and have them enjoy flying the planes as much as I have (will). I've fought a lot of corrosion issues on my Bonanza. Issues that wouldn't have exist if Beechcraft had given thought that their planes just might still be flying in 50 years.

That corrosion is from the inside out. The metal will look like pie crust. It seems that they tried a different alloy for the spar in 46 and it is comming back to haunt us now. Spending $10,000 to fix a bonanza may be justified. $10,000 for a $15000 coupe may not. I still like the primer idea.

The two alloys are not directly comparable so far as corrosion resistance goes. That said, I did find corroded areas on the interior of my first Ercoupe, especially in areas where the moisture was trapped by grease and dirt. As I understand the spar corrosion issue, it relates to the forged end fittings. Proper corrosion protection there might have prevented the problem, but who then expected that the airplanes would still be flying 57 years later. My 601 project has been under construction for longer that I like to admit. Recently I've noticed evidence of surface corrosion on the skins of my tailplanes which have been stored in a dry attic for a few years. I'm glad that I decided to prime all the interior surfaces. I was able to polish the corrosion off the surface, by the way.

As far as building parts yourself it would be diffcult since we are dealing with a certified plane. As far as a "real deal" -buying a coupe as always been a real deal. Keeping one is another story unless you happen to be an A&P. One of our ercoupe members has the orginal plans for the coupe and he says he is going to build one from scratch.

I am lurking for about a year in the GEO list, and I will probably build a 1,300 cc turbo conversion. I posted this because I want to encourage all (including myself) to continue in our projects, same happend to me in my first project and friends help me out with advise & ecouragement. This one is my 5th plane I built, I love to buid planes. Dont give up.

Suit > yourself though. snip. I have seen quite a few wood ultralights that are 20 years old, I bet the builder did not think he was building a plane that would still be flying 20 years later. You may not keep your plane for 57 years but neither did the person who bought the new Ercoupe. If you are going to donate your plane to a childrens museum or send it to the scrap yard when you are tired if it then fine. If not someone will have to deal with corosion someday it just may not be you.

You can run some ducted air to them to help them cool better. They are a poor mans oil cooler. My iA told me about them, they are not legal for the champ but it comes off in about 30 seconds.

Francis owns 4 airworthy and flying Coupes and 3 more that will be flying in the next few years. The other 3 Ercoupes Francis owns are only good for small parts and making really neat tetrahedons ( wind direction indicators) The spar cap that corodes is a complex extrusion and the big rivits that hold the steel forging that helps corosion of the aluminum can be fixed but is time and skill intensive. A nice Ercoupe is not worth the time and money it takes to turn a junk coupe into a nice one.

Moving the pulleys might have changed the geometry such that the cables do not remain taught. I'd recommend making a drawing showing the dimensions of the modified control system and send it to ZAC for evaluation unless you know either an aeronautical or mechanical engineer who can evaluate the geometry to determine if moving the pulleys might be the issue...
