| Subject: | Re: Gross Weight increase |
Well, it seems there is no great desire to increase the load on the Pulsar's out
there. My local inspector suggested that if the right calculations could be
done, reducing the G limits could allow for more weight. I guess no one has done
it. The higher G limits of the Pulsar suggest that there is some margin there
but I'm not about to be the test pilot. Have to wonder about what the heavier
examples are doing though? Mine weighs an unconfirmed 620 lbs which I think
is heavy, but have a look at the one on Barnstormers for sale which weighs in
at 800-something with a 1200 gross. After full fuel he has less than 250lbs left.
So, maybe the right question should be, what sort of things will reduce the empty
weight? With a vacuum pump and a six pack, plus a radio and transponder there
is definitely room to shed a few pounds, but I'd like to keep all these! A
Dynon is a possibility and it would eliminate the pump. Some lighter radios are
possible. But all this comes at great expense. I'd like to get the weight to
600lb but is that realistic? How many owners have Pulsars that weigh in at 600lbs
or less? And if they do, what sort of equipment do they have?

Chris,
For weight comparisons, you need to know the exact model and possibly the
serial number of the other planes. I don't have the info but I'm sure
someone here can tell you when and how the various models changed and how
that relates to expected empty weight. Mine is a Series 2 with Rotax 912S
and weighed in at 685 lbs empty when first built. Like most planes, it has
gained weight over time with the addition of another auto pilot, CS prop,
fire repairs, etc. To compensate, I have lost a little weight.

Hey Jim,
Mine is an XP 912. Serial # 462. I have composite spars and skins, and a heavier
duty nose gear (one with an aerodynamic shape instead of a tube).
My manuals are a dec 1994 revision.
Another local guy suggested that body filler has added significant weight to some
examples. I never did check his weight but his was a beauty with dynon, avmap,
and some nice innovations for flap handle, ventilation, etc.
My biggest challenge is that I need a stainless firewall and the current one is
aluminum. Engines gotta come out. I need a gascolator too and carb heat. It's
just the regs here in Canada - no exceptions.

Chris,
Mine is #456, xp with 912 engine. It has a few "improvements" including an ss firewall,
electric flaps, etc and weighs in at about 648 lbs. Can carry two lightweights
like me, full fuel and a little baggage. Never felt the need for a greater
weight limit.

*When I built my XP serial #394 I stated the gross weight as 1100lb.
Composite Spars and skins on the wings.
On a certified plane you would need and STC and form 337 to change the
gross weight.
Since experimentals do not have STC's or 337's a log book entry should
make the change.
The FAA could consider it a major change and require 5 or 10 hours of
test flying without passengers.
On the question of is the plane strong enough to handle the gross weight
increase consider Bernie unplanned high speed test flight way over red line.

There are people who are flying their Pulsars a little heavy. Haven't
heard of one breaking yet.
Of more concern to me was the CG calculation. With my XP if I load to max
gross and then run the wing fuel cells way down, I bust the aft CG limit.

My Pulsar XP weighed in at 568lb when first constructed. 1060lb was
the design limit for my model. Like all aircraft it has gained weight
since with a constant speed prop and several other fitments. I have
done the conversions into pounds to see what I sometimes carry and there
have been times when it has been loaded to 1150lb. The main thing I
have found you need to watch at these weights is the stall becomes more
of a snap than a docile departure and as Bernie says if get low on fuel
your CoG goes a little too far rearward. I am nearly always carrying
60lb in the luggage compartment as I take my Border Collie with me
everywhere plus tools, tie downs and first aid kit etc. The dog weighs
44lb of this lot. So they will carry the load but I don't take it into
any turbulence or throw it around when I am over gross.
