Post subject:  442E plans not complete?

Downloaded and am about half way through building my chassis when i realized that anytime i download the file, I only get 50 pages. Its missing all the suspension plans and everything that is past page 50. Is this something wrong with my download? or am i missing something?

I get 52 pages total. But read the note on his website:

Chassis Plans
The chassis plans on this site are based on the original Locost design presented in Ron Champion's book. The plans are not complete, but they should provide you with a very good (and very accurate) starting point. You still need a transmission tunnel and certain triangulating members that are not shown. Be sure to refer to the book for these structurally critical pieces. I've excluded them from the drawings because each builder tends to customize the transmission tunnel to meet their needs (cut-to-fit). The missing triangulating members were simply too difficult to model with the computer.

McSorley 442 - Plans

An increased width, length and height using the nosecone and suspension mounting points suggested by the book. The increased width exists through the rear and the cockpit, while the front end is based on the book chassis and it uses a standard nosecone. The suspension brackets can be mounted according to the layout provided by the book, but the length of the front wishbones should be customized to be sure the track width agrees with the donor axle following assembly.

The increased length provides an additional two inches for the pedal box and another two inches in the engine bay. The increased height goes through the horizontal portion of the chassis (forward of the dashboard) to balance the over all design and accommodate taller engines. A standard nosecone that is 26 inches wide at a distance of 12 inches from the front should fit with little-to-no modification, although a tall "cowcatcher" is called for to bridge the bottom of the taller chassis with the bottom of the relatively stout nosecone.

There are some vendors manufacturing nosecones that are taller than the book design to provide even more height for the engine. For example, Champion Motor Cars used to produce an oversized nosecone that sits 13" below the top rails and an additional 1" above the top rails... placing a full 23.5" under the bonnet while leaving a relatively small 2" gap along the bottom of the 442 chassis. This oversized nosecone is still available from certain vendors. A standard book nosecone leaves a 5" gap along the bottom of this super-sized chassis, but the width is spot-on.

Sounds like the more info you are missing is provided in "the book" or must be created by the builder.
