With the Bing carburetors it's hard to see the throttle plate. I thought I was going insane at first because another builder said that he didn't understand what the heck I was talking about, but I finally figured out that his bing carbs had the carb throttle linkage closer to the front of the plane where mine is closer to the firewall on the plane. From what I've been told, Stratus had to move the throttle linkage because they could no longer get the smaller starters and the new ones interfered with the throttle linkage. I've also test fired the engine without any throttle cables and it sits at idle. Another local builder that has his plane setup with the smaller starter and forward throttle linkages goes to full throttle unless you pull back against the throttle linkage spring. Thanks!

Without diminishing the merits of other engines, in the end I was impressed by the ability of the 912 to complete a number of recording breaking flights including around the world (by trike) and 2 trikes from Sth America to Sth Africa. Colin Boddill (sp?) also flew a 912 powered trike from the UK to Sydney. The engines performed magically on varying quality fuel and in extreme conditions. Many other engines are fine for our needs, but when an engine has this kind of record, I think it excels. I've also seen some convincing evidence showing that despite the cost of 912 parts, the 1200-1500 hr TBO, reliability and fuel burn make it a cost effective option in the long run. However, having said that, the upfront price is hard to swallow.

So the following obviously isn't worth much. But, having looked at the video of the crashed 801, I cannot help but believe that this airplane exceeded VNE and/or structural load limits. The impact forces on the fuselage appear to have been EXTREME, far worse than I would guesstimate for a fuselage falling to the ground after some kid of structural failure at cruise speed. My further wild guesstimate is that we are looking at a misjudged recovery from a dive, with parts lost trying to pull out before impact. Langewiesche describes precisely this kind of accident in "Stick and Rudder," and mentions the likelihood that the aircraft will experience structural failure prior to the impact itself. An awful thing. The human tragedy is enormous, and obviously the technical issues are a matter of great concern to the 801 building community as well. I'm confident that ZAC feels the same way and that we will see responsible action and assistance on their part.

I'd like to install a fitting on the bottom wing so that a heavy duty hose (or maybe even the plastic tubing) can be used to connect to the wheels. That way, if the outside portion gets damaged I don't have to worry about accessing the internal wing plumbing. I'm assuming I need some sort of bulkhead type fitting but I'm at loss for which one and how it would install. This seems like it should be easy, but I just don't see how to do it with the existing fittings and none of the ones I see in the catalogs seem to make sense either. Thanks in advance....

In my opinion, that is the only way to go. If you have a throttle linkage break, best to have the throttles go full open. You can always then cut the ignition when you see that a suitable landing site is in reach.

They make a good selection of fittings, in aluminum, and they make bulkhead unions that allow you to have rigid aluminum tubing inside the airplane and flexible thick-wall Nylon outside the wing.

You can also adjust the depth of the seat bottom during construction. I saw a shorter builder that made his seat deep, and then put styrofoam in the bottom, because he wanted to be able to accomodate taller passengers and pilots. --> Zenith-List message posted by: "Gene Z.

"Boiling over"; looking for suggestions? --> Zenith-List message posted by: "royt.or" Hi, I've started testing my Rotax 912S and run into a problem. I've mounted the slightly larger 912S Rotax oil cooler in the original Zenith position, below the PRSU. I've mounted a rotax radiator in the cowl on the right side of the engine. I built a plenum (? box) which directs air from a 3.5 inch SCAT hose through the radiator. The 3.5 inch SCAT hose has a funnel shaped intake at the front of the cowling. The top of the radiator is below the expansion tank on top of the 912S. I have a 3 (tapered) blade Warp propeller, set to 15 degrees I think. Max RPM with plane secured is 5000. EIS for engine instruments. When I run the engine at 3500RPM or more, as it heats up, the radiator cap on the expansion tank opens, over filling the coolant bottle and making LOTS of steam. I've adapted a hose on my vent which I run to the left wing, allowing earlier detection and reducing the mess as well as reducing the dramadramatic. The radiator cap opens as the CHT readings reach 80C. I've installed a coolant temperature sensor at the outlet of the radiator and it indicates 50-55C when this happens. When the engine cools, it pulls a pint or more of coolant back into the circuit from the coolant recovery bottle. This happened initially with the cowl on. Most of my test since then have been with the cowl off. I believe I've purged the system of air. I'm near Portland, Oregon where the temp's have been around 40F. I plan to try a new radiator cap. Any other suggestions/ideas? Regards, Roy Thoma prefered email roy.thoma@intel.com N601RT - CH601HDS, 99.44% ready to fly. Rotax 912S, external alternator, nose gear, all electric IFR.
