If any of you are lucky enough to make it by Jim Hoak's Sheet Metal Workshop at
Sun 'n Fun, or even just meet Jim and shake his hand, you'll connect with a guy
who is the spirit of EAA embodied. Jim has built a Zodiac himself, and as
a Tech Counselor has been closely involved in the building of several others.
In February he spent 5 days in Charlottesville helping me backwards engineer
and repair a very problematic section of my 601HD aft fuselage that had me
in a state of frustration and befuddlement. When he left, not only had I learned
the equivalent of a college level course in sheet metal, we had completely
figured out and strategized the repairs that needed to be done in this area of
my project that had stumped several guys a lot smarter than me.
Most of the guys I consulted about the problem had said "I think it'll be ok".
I know what they meant was "I'm not sure what to do about it, I'd probably just
fly it that way", and I might've too, but it didn't seem ethical taking passengers
on an even marginally questionable platform. Since Jim was here, I'm
finally moving forward on completion, and for the first time feeling excited
about the fact that I finally know all I need to know to complete this project,
have fun doing it an experimental way, and stay well within or exceed published
minimum standards. (I didn't attend the rudder workshop because I'd purchased
my project partially completed from a father-son pair of builders who were
aircraft mechanics. Little did I know I'd spend the next year repairing their
mistakes.)
So if you see Jim, tell him hello for me, will you?
And if you want to learn more about building with sheetmetal, I expect you'd get
a lot from his workshop. Jim has a passion for sharing his experience and knowledge.

Dear Listers,
My sincere apologies! At about 4:30am this morning there was an odd system
problem on the Matornics email server, causing many mail files to become
marked as "read-only". This wedged many of the List filters causing all
sorts of weird behavior. Perhaps the oddest was that an innocent message
from Walter Critchlow, kept getting posted instead of the actual incoming
List message.
If you receive this message, and sent a list message to any of the lists
shown below between the hours of 4:30am and 5:15pm PDT on Sunday Apr 10th,
your message was one of the ones that got subverted. Please repost your
message to the respective list.

This advise will sound a little tricky but has worked great in all the 912 engines
in the club and also was OK'ed by Kodiak Sevice Dpt., though our Certified
Rotax Mechanic.
We have the engine idle set for 1,300 to 1,400 (dificult to set exactly, as closr
to this figures as possible). BUT this idle speed is ONLY USED when flying
the aproach to land and for start with the choke (when required). Once
the engine started and the choke is release we inmediatly pull the Throttle to
2,000
When warming up, or at the ramp, or waiting for take off at the strip, we set the
engine at 2,000 rpms with the trottle and brakes.
The reasons are this:
1.- Set to 1,400 because:
The choke will not work properly if the engine is not at idle, never had a problem
to start the engine at this setting. This rpms (1,400) because at the
less idle speed is better to slow down the airplane approach speed, we have tested
to set it lower than 1,400, but in two ocasions the engine died, so is a
risk we dont want to take.
2.- Keep the engine at 2,000 because at this speed runs smooth, betwen 1,400
and 2,000 there is sometimes a "rattle" form the clutch or maybe the transmision.
any strange noise whatever is the surce we try to avoid it.
Is very easy as a pilot to get used to set the fricton throttle instantly at 2,000
Just needs a little practice. Use your finger against the panel to feel
the little movement.
Hope this helps.

What idle speed do you manage to get down to on the Rotax 912?
Obviously this needs to be as low as possible so you don't extend the
landing roll more than necessary. Some recent measurements here in the UK
have indicated that having the idle too high by just 30% above normal can
increase the landing distance by an amazing 60%.
We find that ours on a 601HDS just will not tickover below 1000 RPM or so
without the engine jumping around so much that you can't keep the
screwdriver in the adjusting slot. It does not get smooth until 1200-1300
RPM and we use 1700 during warm up. No amount of carb balancing will let us
get below this figure.
Having gone through the broken mounting brackets saga last year we are
paranoid about engine stability so tend to keep the revs high.
What speeds do others manage?

No advise in floats... Yet, only wheels.
Your altitude, temperatures and surrounded peaks are similar to our area, we
have cruised to 12,500 ASL at gross with no problem at all. We have flown at
gross (two adults, full tanks and maximum baggage weight as per manual), with
no climb or performace problem noticed...
Our 701 climbs and cruises perfectly at 5,000 rpm (engine "likes" this setting),
we even had a 1,000 ft/min thermal climb at cruise for one minute... we were
"transfered" from 10,500 to 11,450 very easy without any problem, no imput but
keep the plane level, the downdrafts are also similar here . Cruises at 83
indicated (87 GPS average both ways almost calm winds) we have flown for almost
4 hrs, at a little over 4 gph @ 5,000 rpm.
Very confortable seats.
The plane performs great at altitude with the 912S.

Hi I am a prospective 701 builder. I am looking for some basic performance
figures of a 701 with the rotax 100 hp engine and floats. I am most
interested in speed, range, service ceiling and useful load. I also know
there are two different types of floats available (the ones with 4 wheels or
3) I have a house at Lake Tahoe where this plane would be based. It is at
6000'. It is also surrounded by 10000 foot peaks. Ideally I would like to
use the plane to commute the 300 miles to my other house. Density altitude
can be a major problem because the temperature in the summer can get hotter
than 80 degrees. Please let me know if you guys think the 701 fits the
bill.
Thanks,
David
