Need Rotax 912S Help To Get The 7-Oh-Fun Back Home

I need some Rotax advise as my plane is stranded at another airport.

The coolant overflow bottle failed in flight. The first sign was some red fluid in the cockpit a few minutes after take off. At first I thought it was brake fluid.

I noted the EGTs were high, but the CHTs were in range, and the oil temps were slightly high, but not in "the red zone"

A minute later I started smelling something in the cockpit and turned back to the field at reduced…

Phase one complete!!

My Zodiac 601 XL-B has moved past phase one flight testing and handles beautifully! The visibility and flight characteristics are better than I imagined and  I have just flown from the test area back to my own (rented) hangar in PGD! I expect to still have a few items that will need attention as I continue to do a pre-flight inspection like it is my first flight each time. Do not take anything for granted. I will be writing an article about the build as well as the expectations that were…

Flight Test Complete.

Phase I flight test completed 9/26/2012.  Phase II now active, but weather has prevented much flight.  The weather around here (Pacific NW rain forest) should clear up around May 2013.  I plan to do some real cross country flying at that time.

All problems fixed in Phase I except lack of yaw stability.  That seems to be inherent in the design.  There is no vertical stabilizer because of the full flying rudder and no portion of the fuselage side is…

Upgraded plans

I purchased the upgraded  Z-750 plans & the instrument panel blank so I could start the project by transferring my avionics and instruments to the panel. This way I can get the project going while I get the shop set up and decide how much scratch building I could or should do?

I am also thinking about going to the rudder workshop and while there purchase some of the tools I will need for the build?

Cross country trip in Australia.

Just flown my 701 1034 nm from Yackandandah in Victoria Australia to Townsville. Two days 13 1/2 hours. Great trip apart from a small whirlwind tried to flip the plane whilst I was on the ground refuelling.

For all those of you that are still building I can say that it is all worth it. The only thing I would change now is to reduce the cabin noise. Don't know how i am going to do that yet.

Looking forward to exploring a new area.

Elevator Nose Rib Redux

After several attempts of measuring and forming rib molds, and then nose ribs themselves, I finally formed one that I can use to replace the factory rib I damaged some time back. With it on, I have replaced the nose skins and have drilled them out to final size. Should be able to finish pretty soon (which is a relative term since I've been working on the tail since April!). More pictures to follow.
