I believe that the early Pulsar had added plies in critical areas to accept higher loads of a 912 than the initial design with a 582 engine. I don’t know the exact details of the beef up. But as Mike indicated, messing with the design can make
for regrets in added weight and insufficient strength improvement..

Subject: "Beefing Up"
From: "Yellowhammer" <coyler(at)sthpk-12.net>


Greetings Folks,

Read an ad for a Pulsar Kit number 1 for sale and it said it had a beefed up fuselage.
Was just curious as to how folks are beefing up their fuselages or if
anyone has beefed up other parts of their planes.


If so, what did you do to make it stronger?


Thanks,

Yellowhammer

Subject: Re: "Beefing Up"

I=99ve built in a couple of hard points to accommodate an over-the-sh
oulder
angle for the safety harness and a couple to allow removal of the seat
back. The technique is similar to the one used to install the engine
mounts. The main difference is that the engine mounts transfer load
directly to the embedded unidirectional glass. What that means to me, an
amateur builder, is that my mods need to be conservative - in terms of
structural integrity. Because these mods were important to me, I paid the
penalty of a slight weight hit in order to beef that structure up. My
advice would be to build the plane exactly as it was designed. If there
=99s
a standard feature you just can=99t live with, seek the advice of an
experienced builder before even contemplating a change.

The fuselage and tail surfaces were made with heavier glass to take the additional loading. I have the spec somewhere. The spars were also made for the load. Sonya studied the design and and came up with a way to beef up the original structure but it had to be done before assembly started. You could not take a finished aircraft and retro fit her mods.

If I remember correctly, the 912 fuselage was made of heaver composite fiberglass compared to the 582  model.
