That little fan has a powerful magnet, and if located in the vicinity of your compass will induce significant error. I spent a lot of time fabricating a ducting system and air-redirection-switch-box, but now realize the anticipated location of my fan would have been a problem, so am having to rethink the plan!

I was waiting until after the initial flight testing to install them. But after my front wheel bearing and nose fork failures I've decided to leave them off. I'd rather have a clear view of the wheels during preflight than gain a few mph in cruise.

Normally when this question is raised the kit builders have a field day espousing the virtues of building something thats almost half finished when it comes out of the box (slight exageration). This time we got a pretty well reasoned response, My background includes a kit built (Glasairl) and a plans built (RV3) I'm building a 701 from plans and keeping up, almost anyway, with some of the kit builders. In 10 weeks I had the "kit" built, with the exception of bending the gear and welding the mount. One of the things I haven't seen addressed is wait time from Zenith on parts screwed up by the builder (happens sometimes) or wrong out of the box. If you are a plans builder you can rebend a new part for almost nothing in the same time the kit builder can make out a check and drive to the post office. I think the amount saved in $$ has been understated as my airframe will come in under $4K ready for panel stuff, wheels, brakes and engine. Figure it up, the basic airframe weighs 400#s plus or minus a little , aluminum goes for less than $3 a pound plus 20% for waste. The suggestion to scratch build a component , rudder or something, and then evaluate is a good one. Either way thou it's a neat flying airplane and worth building.

The so-called presence of mind doesn't work as fast as "I'm supposed > to turn off the ignition". Perhaps then the happy compromise is to have the throttle 'spring-loaded' to full open, but not so much so that it will instantly pop to that position, giving the pilot time to catch up. In flight the engine vibes will help assure that the engine will smoothly accelerate to full 'on' mode... just a thought. -- Grant Corriveau C-GHTF / HDS / CAM100 ________________________________ Message 14 ____________________________________ Time: 05:03:44 PM PST US Subject: Zenith-List: Re: Zenith-List Digest: 21 Msgs - 01/15/05 From: Grant Corriveau --> Zenith-List message posted by: Grant Corriveau > While Dirk is correct the VW with redrive on B.J.

In fact the Center of > Gravity of B.J.s plane is almost EXACTLY the same as the 912 Rotax. I believe that answer contained some other aerodynamic errors too, btw. A heavier aircraft does not have a shorter glide ratio than a lighter one. It will cover the same glide distance, just at a faster TAS. (assuming the wing is being flown at the correct angle of attack for best glide)... While, in the case of descent at a constant airspeed, a heavier airplane actually glides further than a lighter one. The lighter aircraft must descend more steeply to maintain that 'constant airspeed'... this difference is usually minor in the weight ranges we're flying here, but with larger aircraft with a much larger possible weight range, it is one of the factors you'd need to consider in planing 'the perfect descent'.... and a glider pilot in competition may carry ballast in order to increase his 'penetration speed' i.e. the amount of time it takes to get from one updraft to the next (but I'm not a glider pilot, so please correct me if I'm wrong). fwiw -- Grant Corriveau C-GHTF / HDS / CAM100 ________________________________ Message 15 ____________________________________ Time: 05:18:55 PM PST US From: scotty scotty Subject: Re: Zenith-List: speaking of engines was vw engines for ch 701 --> Zenith-List message posted by: scotty scotty Bob (and others intrested): I'm about 3/4ths of the way to having a Hirth F30-100hp installed in my 701. After checking, i wasn't able to find any info from previous installations of the engine(Zenith, Hirth, or newsgroups). I recieved it in mid October from Recreation Power in Ohio. They have been very helpful. So far: welded up an engine mount, homebuilt alum cowling, currently building cooling air ducts, but still have to mold a composite nose cone for front piece of cowling, and weld exhaust brackets. The most challenging was deciding on exhaust layout, Hirth has 3 options, but after Rec Power sent one of each, so no problem after that. Hope this helps and i'll let everyone know about it after a few flights.

Ask yourself: 1. Do you spend a lot of time in the workshop/shed anyway? Do you continually think of things to make/build for stuff around the house? Do you have other hobbies which involve mechanical/fabrication skills? 2. When you build (anything) do you get a real sense of satisfaction from it? Do you go back and look at it repeatedly? Do you show other people? Do enjoy thinking of ways to make it even better? 3. Do you already have a reasonable collection of tools/machinery? Are you intrigued by new tools/machines for sale? Do you have lots of technical information in magazines,journals etc. 4. OR do you build/make things reluctantly, because it's cheaper. When you're finished is it more a sense of relief than accomplishment? Do you look forward more to USING the thing you're building than getting it "right"- just the way you want it? If you mostly answer "yes" to 1-3, then you most likely have the mechanical aptitude and INTEREST required to build. After that, the issue is how much you like building and how much flying. If spending time in the workshop is just as much fun to you as flying, then maybe scratch building is for you. Otherwise I'd say just get a kit. If 4 is more like you then I would recommend purchasing a built plane. You're interested in flying much more than the PROCESS of building. As for me, I would never have gotten through this long rebuild/mod process without the help of someone who has all of these builder qualities. I'm afraid I get about as much satisfaction from closing the wings up again as finishing mowing the world's longest lawn! I would much rather be flying and every rivet, hole and bend has been an obstacle to that. Yet oddly enough, I will fix computers and anything IT from "model T" computers up, and think nothing of days spent configuring a network. That's fun for me. Different strokes "Know thyself" is always worthwhile and before committing a really big slab of your life and that of the people IN your life to something as big as building a plane, I suggest you take a long hard look at the navel. It might save you a lot of money, your marriage and maybe even your life!
