Just have not thought of it. As to the location of the flap switch. I have dual controls and dual throttles and I mounted the flap switch on the console. So in landing I would have to take my left hand from the throttle to the stick, right hand from the stick to the switch and reverse the steps to get my left hand back to the throttle. Made one landing like that and then added a second flap switch up on the panel so that I don't have to remove my palm from the throttle ball to finger tickle the flap toggle. best regards, Bill ________________________________ Message 7 _____________________________________ Time: 08:55:28 AM PST US From: Brad Larson Subject: Zenith-List: Any 701s with A65 engine --> Zenith-List message posted by: Brad Larson Subject it all....

Look" > > Is there any difference between green primer and yellow primer other than > the color? > I just ordered some spray bombs of zinc oxide in the yellow. Steve, there is no such thing as a dopey question in aviation. :) I'm assuming you're talking about the zinc rust inhibitors. These are not very good primers for paint despite what the ads tell you. The green stuff is zinc chromate, the yellow stuff is zinc oxide. Zinc is what does the work of delaying corrosion of Al. The chromate is considered much more harmful to your lungs, although I don't know how that conclusion was arrived at. So you should be using the oxide. Some of us like to brush it on instead of using the aerosol to avoid breathing in the overspray. Mechanically there doesn't seem to be any difference, both can be scratched off with a fingernail. For actual priming before painting you should remove all traces of zinc from the painted surfaces and follow the preparation procedure for your paint of choice. I like the DuPont self-etching primer for its user-friendliness. You can get it at any auto paint store.

Ear plugs do a fair job for hearing protection but don't do a lot for the low freq noise. A head set covers and protects the area behind your ear where a lot of the low freq noise is transmitted. Take it from a guy who has trouble with my hearing each year at my Air Force Physical. Protect yourself.

Steve: I've put several homebrew inspection/access panels on my 701 wings and they've turned out pretty good. I can send photos and more dimensions off line if you want. I went with 60mm dia. holes under each fuel tank outlet with top-mounted covers, 70mm dia holes on top of each VDO fuel sending unit with flush-mounted covers, and 90 mm holes with top-mount covers near each front upper strut fitting. Paranoid about those three attach bolts I guess, probably for no good reason. Also 110mm flush-mounted access holes on each wingtip. Just large enough to get the strobe power supply out. All have .025 or .032 doublers and use nutplates with countersunk rivet holes so the covers sit down nice and flat. If you decide to put them in, make them in batches vice one at a time. Saves a lot of layout and drilling time, and your covers will all be interchangeable when you get done. Some people bust on Zenith for not having CNC holes and stuff like access/inspection plates in their kits, but I'm fine with it.

I=92m now trying to figure out where I=92m going to put everything once I start inventorying it, (I need to get my work table built first before I inventory, because I will be storing longer items on a shelf under the table). A few questions regarding inventorying and storing: * I assume you need to unwrap things to check part numbers against your inventory list. Is it best to re-wrap before storing to provide added protection (especially the sheet aluminum)? * There are two rolls of flat aluminum sheet, approx. 3=92 to 3=92 3=94 wide. They are not marked on the outside wrapping, like many of the other items. Any idea what these are, and can they be stored this way or do I need to unroll them? * Does anyone have a good technique for safely hanging smaller completed components, such as the rudder, on a pegboard wall? I have some space where I could hang my rudder, and eventually the rest of the tail feathers, but I don=92t know a safe way to do this Thanks in advance.

The VG's did lower the stall speed a few kts (sorry I don't have an exact improvement), they did not significantly alter the top speed, they did allow very steep climbs. The VG's reduced my cruise efficiency. That is it took noticeably more power to go the same speed. They also reduced the climb rate and reduced the max ceiling of N601RT. This was disturbing when flying at 10,000 to cross the Rockies. Bruce N269BB (Subaru powered CH601HD) and I flew from Colorado to OSH together in 2003 and in 2005. In 2003 (no VG's on N601RT), my rate of climb matched or bettered Bruce's. In 2005 (with VG's on N601RT), Bruce easily out climbed N601RT. This is not purely scientific. Bruce's wife was with him in 2003, both planes have more hours, etc. It is worth noting, in 2003 Bruce's wife rode in N601RT and my O2 bottle rode with Bruce, N601RT still matched or bettered the climb performance of N269BB. At OSH 05 Chris said that the 601 wings are too fat to benefit from VG's. I did discuss VG's with a Rans S-10 owner who was very happy with the VG's on his plane. He said that it took quite a bit of experimentation to find the best placement for them. Maybe my measurement of 10% chord was incorrect or not the right placement. Regarding cleaning the plane with VG's. I agree with Bill that cleaning the wing is more difficult with the VG's in place. The bugs may not be where the VG's are, but my plane still needs to be cleaned of dust, and other crud that accumulates over time. YMMV. Land Shorter says they have a money back guarantee. I have not tried to return my VG's. Regards, Roy N601RT: CH601HDS, nose gear, Rotax 912ULS, All electric, IFR equipped, 467hrs, 569 landings I had land shorter vortex generators on N601RT for ~45 hours this year and was not thrilled with them. The VG's did lower the stall speed a few kts (sorry I don't have an exact improvement), they did not significantly alter the top speed, they did allow very steep climbs. The VG's reduced my cruise efficiency. That is it took noticeably more power to go the same speed. They also reduced the climb rate and reduced the max ceiling of N601RT. This was disturbing when flying at 10,000 to cross the Rockies. Bruce N269BB (Subaru powered CH601HD) and I flew from Colorado to OSH together in 2003 and in 2005. In 2003 (no VG's on N601RT), my rate of climb matched or bettered Bruce's. In 2005 (with VG's on N601RT), Bruce easily out climbed N601RT. This is not purely scientific. Bruce's wife was with him in 2003, both planes have more hours, etc. It is worth noting, in 2003Bruce's wife rode in N601RT and my O2 bottle rode with Bruce, N601RT still matched or bettered the climb performance of N269BB. At OSH 05 Chris said that the 601 wings are too fat to benefit from VG's. I did discuss VG's with a Rans S-10 owner who was very happy with the VG's on his plane.
