"Just got my plans in the mail… they are very detailed.  If anyone is looking for plans that don't require guessing or trying to get inside the designers head these are for you. About all Rorty hasn't done with these plans is come over to your house and start fab work for you".

"Received the plans yesterday and spent all last night going through them. Wow! …these plans are nicely done, what a work of art".
R. O’M. - Lakeside, California, U.S.A.

"I received my plans and as always they are incredible".
T.C. - Evanston, Wyoming, U.S.A.

"Thanks for the great set of plans. Very fun to build from".

Don't confuse this buggy construction manual with the backyard type buggy plans advertised in the motoring press and elsewhere on the net.

The R16 Shotgun II comes from a long line of successful buggy designs used both in competition and recreational driving.  

The word "shotgun" has been used since the coaching days of the Old West to describe the seat beside the driver where the shotgun-wielding guard sat. This two-seater buggy is aimed fairly and squarely at the American market, so how befitting to name this model the Shotgun II!

The main structure of the Shotgun II's chassis is constructed from 1.5" DOM tube (as opposed to 1.25" tube of earlier buggies). This provides an immensely strong chassis and interestingly, the 1.5" material is actually cheaper than 1.25" tube! The larger diameter tube will also make the Shotgun eligible to enter a variety of race series in the US and other countries too. 

The Shotgun II boasts a mechanical gear shift paddle situated directly in front of the steering wheel which makes changing gear swift and positive. Drawings are also supplied for those wanting a more traditional shift lever. 

Custom manufactured parts have been kept to a minimum which will make it easier for those without metalworking machinery to assemble their buggy. For the diehard machinists and fabricators who would rather make everything than pay for someone else to do it, full working drawings of all the "off-the-shelf" parts are included in the manual too. 

Check here for any additions to the Suppliers List, or updates to the Parts List, drawings and specifications.

All up, there are 108 technical and working drawings which will print onto US standard 11" x 17" Tabloid paper. Have a look at the two sample drawings on the right. The drawings show dual dimensions to suit everyone: The metric measurement is given priority and is followed with the decimal inch measurement in brackets.

The construction manual contains further colour illustrations throughout the text and as usual, there are full fastener, material and parts lists all of which will print onto standard US 8.5" x 11" Letter size paper. 

Many of the parts required for the build are available from all the usual off-road shops and auto stores. Virtually every custom part is now available for purchase from just one or two suppliers within the US, so building one of these buggies couldn't be easier.   

I have worked with Dan from RPM to come up with the best reverse box set-up available for the Shotgun. A new RPM FNR box is available for the Shotgun with an inboard brake disc and is without a doubt, the best, most reliable reverse box that money can buy.  

Not everyone wants, or needs a reverse box, so I have included drawings of the non-jackshaft cassette that I used way back in the R4. There are no big expensive bearings like the later twin-shaft cassette, just a couple of common bearings, a sprocket and a brake disc & calliper. The cassette also accepts the familiar 930 CVs, and a simple double ended adjuster takes up any slack in the drive chain.

Be warned! The Rorty R16 Shotgun II is not for the feint of heart. An R16 Shotgun II fitted with a large 4 cylinder bike motor can punch out over 400 BHP per tonne, and can accelerate to 100 kph (62 MPH) in under 4 seconds, with speeds approaching 200 kph (124 MPH)!
