The biggest advantage is that you cannot snag a brake line & rip it off during a take off or landing (hence loose your brakes). This is far more likely to happen in "Bush" type runway environments. It also looks much cleaner/neater.

For those non-tail dragger pilots, let me tell you that wheel landings in a tail dragger are a piece-o-cake.

Did you have to disassemble or take special care with the latch casing before welding it to the steel plate? And before welding the lever extension to the lever? The guy who does my welding is concerned about changing the tempering of the springs (or even melting them).

McFarland" Subject: Re: Zenith-List: Canopy arms (6C2) --> Zenith-List message posted by: "Larry C. McFarland" Welding latches in place August 28 An order was placed with Wicks for 1/16-inch cable and housing, 1/16" nicopress sleeves, engine mount bolts, cable stops etc. A review of the drawing 6E4, finds reference for placing the rear bow parallel to 6F12-1, which cleared up the angle intended for the socket tubes. The latches were clamped to the plate 5mm clear of the square tube and flush with the top. Latch action was not functional until the latch was lowered on the plate to within inch of the bottom edge. This, with the striker engaged, puts a 1/8 inch gap between the longeron and the canopy tube. This is noted in recent pictures of the XL in the Experimenter and it would allow adding a weather strip on the bottom of the canopy tube to seal it. The latches were tack welded in place and rechecked for function. Welding was done with a ready water hose on the floor near the garage door. The first TIG weld was on the bottom edge of the latch to the plate and inch long. The welded latch was walked to the hose and a narrow stream of water was directed at the springs inside the latch and then the rest of the latch was soaked not quenched. The latch was air-dried by compressor and welding continued on a second part of the lower flange to the plate and a repeat of the cooling treatment followed. The gap between plate and top flange was welded along its length and again more water on the springs first and then air. After all was secure, the spring action was still strong and intact. The canopy tubes were reassembled to the plane and latch action was found to be reliable. August 29 The striker plates were marked for position and drilled to a 5/32 for A5 clecos. The holes were placed closer to the steel edge than center because of the requirement for eventually placing the A3 holes in the longerons at a 10mm edge to center distance. Michel, Above perhaps excerpts from section 4 of my journal will help. Yes, the springs need protection but you can do it with a little care. Position is also very critical. Larry C.

If XL, then build the fuselage with the tricycle main gear structure as well as the tail dragger structure, then you have a rear attach point. The front attach point can be the engine mount (weld pick-up tangs on the bottom like the 701 mount) or use the front main gear (weight penalty). If you want amphibs, then you can order our floats with built-in nosewheels. But you have more weight, less rough-field capacity, and more forward CG shift. Incidentally, we fly the first 601XL tail dragger in 2 weeks. Cheers, CHIP Chip W. Erwin CZECH AIRCRAFT WORKS, S.R.O.
