I say "possible" since I don't know for sure how plywood or MDF would hold up for making all the nose ribs (probably plywood would be OK but if you use MDF I would strongly suggest adding the aluminum plate as shown in the plans. MarkTownsend and I made the nose rib forming block from some wonderful solid maple cupboard doors we found at a used building materials recycling store. If you use a good piece of solid hardwood for this set of blocks I know it will hold up. We did not use the piece of aluminum plate on the blocks as shown in the plans and after three sets of nose ribs (48 ribs) the blocks look as good as when we made them. Just one more option - but when wondering about looking to see what might work for what, it is good to know there are options. Happy Building. David Larry McFarland wrote: Answer: Metal form blocks are only nice to have but not a necessity. Use 5-layer plywood from Lowe's and you route the edges. You can file them as well and the aluminum won't know the difference when it's bent. You could probably build 5 or more planes with one set of well made plywood forms.

Really though, a complete list is all that's required. It just takes a bit of extra time deleting stuff that's not applicable to my plane. The extra time wasted is annoying, but sometimes there are things from 701 builders that are also applicable to 601 builders.

Sometimes the tail cone gets a little twisted in the stabilator area, then the stab will not be parallel to the wings, now the only reference you have is the cabin section, no wings instaled yet to check. Hope this helps Saludos Gary Gower --- Ron Lee wrote: > --> Zenith-List message posted by: "Ron Lee" > > I am building 701 with a 912s, and am at the point of installing the > horiz. tail section.

Subject: Zenith-List: Oil heat sensor --> Zenith-List message posted by: "Johann G." Hi list members. I am installing the radiator and oil cooler on the Rotax 912 ul engine. I bought the engine used and it has a oil heat sensor. The sensor sticks forward and will interfere with the radiator. Has anyone used this sensor? Is this information necessary? Just besides this sensor is the oil pressure sensor sticking out to the right. On the picture manual from Zenith, this oil heat sensor hole is closed with a plug. Sorry for not having any pictures, but hope this in not too confusing. Hope you can help. Thanks in advance. Johann G.

Perry" Subject: Zenith-List: Rotax proposed AD --> Zenith-List message posted by: "Richard T. Perry" Folks - I'm hoping that those that are flying behind a 912/914 Rotax engine (or are planning to) have heard about this already, but just in case (and since I don't remember this coming up on this list before), you might want to look at the revised AD they're planning to issue. This is particularly important if you bought your engine (and have it sitting in a crate) prior to 2002-21-16 being complied with. Anyway, take a look at: http://www.regulations.gov/fredpdfs/04-18440.pdf Comments are due by the 12th of October, if you're interested. Yeah, yeah, I know - you're not required to comply with AD's on experimental aircraft. True (although there are exceptions.) Still - something like this is safety driven - it's worth a look at. Mostly, you need to look at replacing the dipstick - that's not too expensive. Regards, Richard T.

Not for overheating but to prevent running it to cold. Here it takes some time (about 10 to 15 min) at 2,500 rpm to get the oil over the minimum required of 50C Is important (is in the manual) not to get over 3,500 rpm before reaching that temperature. and here is not cold year round... Once I read in Sport Aviation (or maybe Kitplanes) that there was an aftermarket valve/bypass for the oil cooler line in the 912 to prevent the oil to get to the cooler until the temp was in the green... Anyone has looked/tested/used one?

I've made some, but since I've been spending most of my free time with flight lessons, the plane building has almost stopped. I was looking hard at brakes and even bought a 30 inch to get me going till I either made or bought a large brake. Guess what I spied recently at my FBO's maintenance hanger. An 8 foot and 4 foot brake. Guess who is going to see if I can use them for a bit when the time comes. As been said previously, Zenith will sell each individual part if needed, so don't sweat it. Just start work.
