Steve, If you can get in there with an of/set drill head my suggestion of the 11/32 drill bit would make the hole only 1/32 too small and provide just enough meat to ream to a perfect tight fit. A 23/64 would work I suppose but not leave much meat to remove and you could over ream. This process requires a twist or two, then check with a 3/8 bolt until you just about have to force it in.

There are various close quarters drills and attachments available. I purchased a used item from Brown Tool, http://www.browntool.com/productselect.asp?ProductID=680 that attaches to my 3/8 electric drill chuck. The used item is a bit beat-up, but functions just fine. Brown sells new ones in various price ranges also. Like most of the really close quarters drills, it doesn't have a chuck. Rather, it requires bits that are threaded 1/4"x28, which, of course, Brown also sells, including very short (9/16"-long) bits for really close quarters. Brown also sells collets which will grip regular drill bits over a narrow range of diameters. (I put collets on my Christmas list for #20 & #30. I haven't used them yet.) Though I am barely into wings, there were a couple of spots on the tail where I used the close quarter drill. It worked like a champ, but I think I'd want to practice a bit before I drilled something thick and really critical like wing spar attachment. Good luck and happy building!

I'd like to get verification of the distance from "pilot hole center to pilot hole center" on 6B6-3 (the Firewall Side Stiffener). Since a picture is worth a thousand words, I've attached a couple of drawings that show exactly what I'm looking for. I have calculated this distance needs to be 476 mm, and my pilot holes seem to bear this out. But still, I'd sure feel better if I knew for sure what the center-to-center distance is on an actual Corvair motor mount actually is.

The prop manufacturer for my 3-blade Warpdrive suggested a 12-degree pitch. Set at 12-degrees, the maximum RPM the 701 can develop is 5375-RPM. The plane seems to fly well with this setting. At cruise RPM (4900-5000) is goes 85-90-MPH and at full RPM, lightly loaded, it will reach the do-not-exceed speed in level flight and climbs over 1400'/minute. I'm satisfied with the performance but am concerned that I can't get to the maximum 5600-5800 RPM that Rotax suggests. Do you think I'm OK with the 5375 maximum RPM, or should I decrease the prop pitch?

I no longer have the Corvair engine and mount so I can't measure how far it was out but I think it was about 2 or 3mm.

I am reporting to you now that I have 60 plus hours on the 601xl with a Jabiru and some thoughts you should take as you complete your steeds: These apply to the first time builders mostly, not the seasoned warriors on this page: 1- Build the plane according to the blue prints, if you want to play around with the design, be my guest just realize that a small change in plans, has a big change in performance, not like a car! 2- The saying "a little is good and alot is better" does not apply to airplane design. The designer did not double the thickness on the skin of the wings for a reason. You are NOT building an RV or an EXTRA 300. 3- Fly the plane according to the specs, example- VNE 160, Manauvering speed 103, cruise(NOT manauvering) speed 130, etc. ITs OK to yank and bank, just do it at the right weight and speed. That applies to any aircraft P-51 to a zenith. The design has a wide envelope of capabilities, and yanking and banking at 93 mph with 20 gallons on board, is NOT doable at cruise speed (130-140mph). 4- If the plane is telling you something, listen to it. a flutter is not oil canning, etc. 5- The plane is not a TOY or a CAR, if you have doubts about your skills, treat the plane appropriately. I am now comfortable enough aftyer the fly off period to take my 4 year old on weekend trips all over the south east. I waited until I was comfortable, and I have 25 years of flying in me. Build the plane like you would want your kids to fly in it. 6- the check list is your Best friend! I have taken off too many times over the years in haste and forgotten things which may have caused serious problems and if I had followed the check list for preflight, I would not have had the problems. Example- cover still on Pitot tube, hence no airspeed at take off, Engine burping and stalling at take off, which was clearly caused by this pilot forgeting to drain the water out of the tank. SAved by practicing to turn on pump and switch the tanks, this would have been averted if I followed the check list! The 601xl is a very fun plane to fly and this family enjoys it and will for years to come. I now undterstand why this design has been around for over 25 years and not much has changed on it. Reminds me of the Colt 45, used in the modern day, but designed in 1905. What I mean to imply is, a good design is a great design, when used in within the envelope it was designed for.

You should consider that your performance optimized to an rpm that mixes fuel economy, low engine wear and less noise. I'd increase the prop pitch to the lowest rpm that still reaches the do-not-exceed speed and still gives satisfactory climb with a passenger. Sounds like you're close, but try 13 and then 14 degrees to see how performance changes.

I am still trying to figure out why I lost everything in my incoming mail but I did so for whoever that was, here is the information you ask for. Richard, Of course I can, that's what this forum is all about. From picture #1, look closely and you will see I had to make a space in the side covering for the oak block. Also the block must be cut in such a was as to fit the inside surface of the fuselage yet come up to the level of the flange where the canopy comes down. The upper block is just a block and requires no fitting however it must be thick enough where both surfaces match (drawing below) In picture #3 the ring in the bottom of the lower latch is clear. Be sure to buy the latches with the ring. In picture #4 the safety pin is clearly seen, this is to insert in the ring after the latch is latched to prevent opening. The safety pin is just a large nail sawed off, one end flatted out and a hole for the string drilled in it. After the two blocks are installed, the next step is to power sand the two surfaces with the canopy closed so that the two surfaces match.

But one thing is important in any airplane: Doesnt matter how overbuilt or extra safety is any canopy or door lock of any airplane, will fail if the pilot will not follow the checklists in every one of the points.

That's why it's an experimental. It's a responsibility that's all to easy to ignore for us kit builders, but it's the reality and something we shouldn't forget. Sounds like there needs to be a checklist item for these latches - another builder responsibility. Perhaps we should all test the strut strength before installation. This is the type of discussion that makes this list so valuable. It must have been really lonely being a builder before the days of the internet.

Pat, I've been late in reading the list lately, so I'm slow in responding to your post. I'm a tall feller and find my knees in the dash panel in nearly every plane I climb into. The factory 601 wasn't the worst, but still too tight for optimal comfort. I very carefully measured, calculated, and consulted Zenith about repositioning the entire rudder channell forward to fit me better. To fully evaluate this, you must look at the intended neutral rudder pedal position, which is more aft than you might think. I ultimately moved the entire assembly forward 60mm (2 3/8"). I can now sit in the cockpit, and all is well. I had to shave the rudder pedals slightly to clear the firewall in the most extreme position, and you would never encounter this position in flight, only while braking during taxi. At 2" forward, even this minor mod. wouldn't be necessary. My floor pan was predrilled, so I had to fill the unused holes with rivets. My firewall slots were cut as per plans, and still fit the steering rods exactly. Zenith had no problem at all with this change.
