Everything is now wired but I am told by my technical advisor I have to take the plane to an authorized FAA station to have the encoder " tuned " in the application and certified. Then every so often it has to be re-certified for accuracy . Even though we have experimental A/C's and can do the maintenance on them the encoder is one thing that has to be calibrated and certified by a licensed technician.

Just one word: Don't! The average car transport trailers are to narrow, it is a major undertaking to get the plane on the trailer, we needed fout people to CARRY it up, as the ramps were to narrow. One wheel was inside the trailer, the other one outside on the mudguard, one wing under the plane and the second on the roof rack of the Landcruiser. It hurt just to watch it, and I spent four hours just packing and strapping it down. Even though it is sold I wouldn't want anything to happen to the plane, and I gave myself the promise that no matter what I will not trailer number two, exept for the first unavoidable trip to the airfield. BTW, I have placed some pictures of my second Zodiac onto photoshare today, any coments are welcome. Cheers, Chris ________________________________ Message 3 _____________________________________ Time: 07:17:55 AM PST US From: "Don Walker" Subject: Re: Zenith-List: Trailering 601 --> Zenith-List message posted by: "Don Walker" Like anything else, this depends on the equipment. When I had a valve guide fail 100 miles from home, I trailered it fine; but it took the right trailer and preparation. The plane rolled easily up the ramp with proper adjustable ramps. Using chocks and ratchet straps to the gear, it rode well all the way. Of course I covered the wings very well to save my paint job and prevent abrasion. This was, of course, a large trailer. 8 1/2 by 32 feet.

Does anybody have comments regarding the use of a 601hds as an IFR platform? I didn't build the capability into mine originally, and was wondering if adding the instruments might be worth it, as opposed to getting something like a 150 that's IFR certified. Thanks!

I don't know which FAR details it. What I did before I knew that, was fly at 6,000 ft MSL per my digital altimeter and ask SoCal Approach for a transponder check. They told me they had 6,010' MSL once they gave me a squawk and I replied.

Has anyone considered tack welding some 1/4" round stock to the holddown leading edge? This might be faster & more consistent than trying to file.

If you relate that to the length of the slot in the firewall for the steering rods, you see the relationship of what Zenair thinks is the absolute maximum travel for the nose gear and see how that relates too.

The air intake is for air input to the engine air box. The scoop supplied with my Jabiru FWF kit is almost flat on it's mounting surface and most scoops I have seen installed are put on almost flat surfaces. The most convenient space I find on my lower cowling is directly under the centerline of the motor and sloping up toward the prop. If I mount it here, I will be placing it on a relatively curved surface and I am afraid it will allow some air to directly impact the duct and pressurize the air thru the duct. Should I mount the NACA scoop on the side of the cowl and use a flatter mounting surface but longer scat hose to the air box, or a more direct route from the bottom of the cowl with a curving installation of the scoop.

We mounted ours on the side of the cowl and that resulted in an almost straight shot to the air box of about 8". I should note that our air box was mounted so that the inlet side was at the bottom of the air box.

I would pay the extra money for modern equipment that is lighter. The 601 is a very light airplane. I wouldn't want to fly it through any severe storms, but you won't be doing any of that during training anyway.

McFarland" Subject: Zenith-List: Transponder calibration --> Zenith-List message posted by: "Larry C. McFarland" Gentlemen, I'm connecting wires between plugs that connect an ACK-30 encoder with a Becker transponder and must ask if there are practical means for checking out the accuracy of the altitude reported. What have you with transponders done in this regard or does one assume that the thing is suppose to work directly "out of the box"? Larry C.

The plane will not fit between the wheel wells of the trailer with the main gear installed so I bolted a piece of 4" steel angle on the inside of the main gear spring on each side with a 4" rubber tool box wheel bolted to the bottom of each angle. I also had to remove the fiberglass tip fairings from the horizontal stabilizer because the door wasn't quite wide enough. Now I just roll it up the rear ramp and roll the nose wheel onto a 4" block to allow the top of the rudder to clear the top of the door and chock it in place and tie it down with ratchet straps. I don't have the wings in the trailer right now but there's room on each side of the trailer for racks fort the wings if needed. I would not recommend trailering the plane on a routine basis, but it can be done. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru. Airframe construction complete.

Might also be better to mount it on the side where the propellor is travelling downwards - i.e. the right side if your prop spins clockwise as viewed from the cockpit. This should boost airpressure entering the duct during conditions of high engine power/ low airspeed/ high angle of attack - fwiw...? -- Grant Corriveau Montreal Zodiac 601hds/CAM100 C-GHTF ________________________________ Message 16 ____________________________________ Time: 04:33:08 PM PST US Subject: Re: Zenith-List: Trailering 601 From: Grant Corriveau --> Zenith-List message posted by: Grant Corriveau I've moved my 601hds from home to the local airport and back twice now using an auto-towing company with a flatbed truck. The driver is getting to be well-trained as other pilots have used him too. The main thing I check is that he doesn't use the hydraulic winch to put too much pull on the nose gear. It makes me shudder to think how eaily this winch could rip the aircraft apart! ;-( The flatbed moves back and down at just enough angle to bring the aircraft on/off with only a slight lifting on the tail at the critical moment to prevent it dragging on the ground as it moves up/down the ramp. My wings fit one-at-a-time in my mini-van, but if I used the roof rack, I suppose I could do them both in one trip. I have looked at the dimensions of a dual snow-mobile trailer (double wide) and it would have a large enough platform. These trailers articulate to provide a loading ramp - but maybe a bit steep for the Zodiac tail...? Again the wings would be best carried separately. The wing mounting / dismounting operation takes about an hour - or two - without rushing. I've done it mainly alone but with another pair of hands to help for a few minutes during the initial fitting or loading/unloading. A good padded sawhorse comes in handy. I conisder this to be an annual event - not a daily or weekly occurance. Seeing as flying weather is pretty poor most winters around here, I've used this time to continue the ongoing upgrading / building / repair process at home in my garage. fwiw. -- Grant Corriveau Montreal Zodiac 601hds/CAM100 C-GHTF ________________________________ Message 17 ____________________________________ Time: 04:33:42 PM PST US From: daddybob Subject: Zenith-List: Tenryu blades --> Zenith-List message posted by: daddybob > --> Zenith-List message posted by: "Charles Hagerty" > > > DB > Where can you purchase these Tenryu blades? > Chuck Hagerty Here's a link: http://www.tenryu.com/series.cfm?ID=15 You just have to check around at tool stores, hardwares, home centers, etc. until you find a Tenryu dealer, or click the dealer link on the link above.
