Have been thinking about doing the same thing Corky. Visited the Ray Allen
booth at Oshkosh and looked at their trim servos. Just $125 bucks, 4 oz.,
and they measure 1" x 2.3" x 2.75". I know its a bit too high tech for a
Piet but if DJ can have a digital engine management system why not? (Need a
battery of course).

Hi Chuck,
Very impressive fuel consumption - I seem to be burning nearer 4.5 US Galls
per hour! Running a 600 hour C65 but with mixture permanently wire locked
rich. I imagine you were leaning out on every trip regardless of altitude -
is this correct? Following some of the engine related presentations at
Oshkosh I think I had better take out some plugs and have a look at them. My
understanding now is that a weaker mixture is actually good for engine
longevity so I'm now thinking of fitting a mixture control.
Regards,
Mike Hayes

At Brodhead, late Saturday afternoon, Ken Perkins' 'A' engine suffered a
problem that was described to me as "The magneto coupling failed.". Since
my Piet also has an 'A', I can't help but be interested in the details about
what happened, so that I might avert a similar failure. Does anyone know
exactly what failed and how?
Visiting Brodhead and meeting some of you in the flesh was GREAT! I'm
already working on my wife about going again next year.

I would have thought that a mag failure on Ken Perkins' engine would have
been less likely than on most others. I've been interested in the dual mag
setup for the A-Model engine which he markets. I would guess that he had
this product installed on his engine. Does anybody out there know for
sure???...Carl Vought

Hi all,
I'm looking at Planers for building the Piet. I saw positive comments
in the archives on the Delta. The Deltas I've considered have been 12",
two blade, and one speed variety around $250. I'm also looking at the
DeWalt 734 which is three blade, one speed at $370. And also the DeWalt
735, three blade, two speed at $500. The best pricing for all seem to
be at Tool King. Would appreciate any comments on these thoughts.
Thanks,
Jack T

All the machines you mentioned are good,but what you want to look for is "how easy
is it to change blades" I run a Ryobi in my cabinet shop and the blade change
is a snap,takes me about 10 min. no brainer type of setup.Also how many sharpenings
are you going to get on a set of blades(I know Delta were very skimmpy
when I looked a few years back)? On the Ryobi the machine will likely burn
out before I run out of blade to get sharpened,allthough somtimes I wonder,as
I have been using it since 1995 and untold thousands of board feet have passed
through it,but my guess is they all will stand up.Just a couple things to consider.Mike

Jack T,
Since you brought it up I will comment on the subject. I have mostly Delta
tools in my shop as that was what was offered at the PX where I shop. I wish I
had gone elsewhere.
Drill Press. Chuck hangs up when trying to go to large shank drills
10 in Table saw. So cheaply built one can't saw a true straight cut
Mitre Saw. Have never been able to square the blade vertically
Electric sander. satisfactory
Mikita drill, Cut off saw and Bosch grinder are all great.
What I'm trying to say is go the extra money and get something better than
Delta
Don't have a planer or joiner as I have access to the woodshop At Barksdale
where they have heavy professional grade equipment.

Mike,
I have been leaving it full rich, until I get to an altitude of 4000 or 5000
msl. My next time up, I'm going to follow Chris's suggestion about leaning it
out before that. If your engine is running rich, it will deposit more
carbon in the engine oil. Another possible cause of running rich, is a float
setting that is too high. Does your carb ever drip fuel ? And a possible cause
of
higher fuel consumption might be using a high power setting, in attempting to
sustain a higher speed. I'm pretty sure I can get a consumption of just over
3 gal / hr, if I fly at just over minimum controllable airspeed. For my
plane and instruments this is at 1750 to 1800 rpm, which nets about 55 to 60 mph
indicated. Can't get there quite as fast, but it's a great way to just take in
the beautiful scenery !!

ps It looks like this weekend I'll be doing some high altitude tests.

Chuck,
The speed you are looking for is Lift over Drag Max--the point where induced
drag and parasitic drag co-incide. The slower you go the more induced drag due
to lift and the faster you go the more parasitic drag increases. Wished I could've
made it to Broadhead, but Uncle Ray wouldn't let me off.

I have a delta, and it works just fine. It is set up with blades that are mean't
to be thrown away, they are sharp on 2 edges so you can reverse them. It costs
just as much to sharpen than to buy a new set. but I have a machine to sharpen
them, so I do sharpen mine.
