How fast is the prop spinning? Are there any power/torque graphs
available for the engine. What's the installed weight?

A P-51!!?? Now that's cool. That R-R Merlin was the sweetest sounding
engine to ever take wing. To be compared to that is just about the
ultimate. All I could imagine before was what a bike sounds like from the
ground.

Isn't this due to not using a restrictor fitting where the oil pressure
line comes from the engine to the switch/pressure gauge?

I bought an oil pressure switch forgetting that there would be a problem
with the pipe thread not being metric. Later there was an accident
reported where the builder tried to use a mixture of threads and in his
case the fitting broke off in flight. He was injured in the resulting
forced landing. I still use my bus bar for my time. Cleone

Actually it is probably a mute point. With a restrictor in the broken line
you get a atomized spray of hot oil, like you get in a jet engine, and with
the rotax that occurs at the front of the engine so you get to spray the hot
exhaust and muffler system. Without it you get a stream about .200" in
diameter which atomizes in the airstream and sprays the exhaust and muffler
system. Either way you risk the flame thrower scenario. At best, a great
deal of smoke and severe pucker factor to the posterior regions. The NTSB
report said the fitting broke. I believe is was a non AN fitting and had a
long moment arm also as contributing factors. Easy to do when stacking two
sensors.

Hi Guys,
I want to express my appretiation for all advices some of you guys gave me
with regard to buying 6061 aluminum. Today it arrived from one of the
wonderful suppliers recommended by our list member from the west coast of
Canada. O boy, I was so relieved when I saw the mill certificates, all
stamps etc. for the stuff. And the biggest advantage - the prices (16 sheets
of 0.020x48x122 for 442 US, 3 sheets of 0.025x48x144 for 103 US, main
landing gear 0.075x3.5x84 for 52.90 US etc.). Comparing the 27.63 US for the
0.020 sheet to 371.00 CAD I was asked to pay for the same thing at local
aviation supplier or 78.50 US at Aircraft Spruce catalogue, can give you
monetary value of my appreciation for these extremaly valuable advices you
gave me.
Probably I will be asking for more advices when I start building sometime
after New Year.
Anyway, thank you very, very much.
Regards to all, Jarek

Jarek: I think if I was scratch building I would still buy the hardware kit from
Zac. Every time I open the little sorted box of parts I am amazed at how complete
it is. Just makes building a little easier.

++ Oil pressure switches are easily available in a number of thread
configurations, including metric. Rely on the dealer you purchased your
engine for advise on the thread type and you'll be just fine.

Here are some pics of the right side vent. I mounted an eyeball vent to get
more controll of directional air & also another way to shut it off by
turning it's ring. The push/pull knob is for the cabin heat.
I got the plans for this on the Zenith site.

Come on Jarek, there are a lot of us still wondering who to buy from. How
about letting us in on the secret. Who did you buy your aluminum from?

Hi Frank.
Noticed your post about Tiny Tach being erratic. Friend of mine had the same
problem on a 912 and asked me to check it out on my 701/912. I had the same
problem.
I experimented and found that enclosing the pickup wire wrapped around the
plug wire with aluminium foil made the tach behave and was within 5 RPM of
my EIS.
I wrapped the pickup around the plug wire about half way between the plug
and the coil then added two layers of aluminium foil over the bundle held by
two tie wraps.
Worked like a charm for me.
Carl

Jarek
I take it this supplier did not carry the .016, 6061-t6 so you went with the .020?
What are the drawbacks of using this size instead of what is in the plans?
Can we do this? I am still in the planning stages of building and I have already
made it a rule that I am not going to try to improve/change any of Chris Heintz's
design whithout approval from Zenith. Did you get approval for this? BTW
I did not see any of the messages from other builders that you speak of. Did
they perhaps email you directly?
