This giant PT boat plan came about as a result of several people asking questions about how to enlarge the smaller semi scale Elco PT boat plans that have been available on this site for a while. If you like them large, this may be the foundation of your next project.
PDF files, as I've learned, are a bit quirky when it comes to enlarging, so being stuck between a lack of control and a sense of responsibility I created this plan set.
Before going any further, realize this is the 1:32 scale plan at double the size, so the propeller shaft, rudder, motor etc shown on the plan are not necessary realistic for this size build, so be prepared to engineer a lot of that on your own.
I would also recommend that some thought is put into the motor installation well before the planking goes on. It will take a good amount of power to get this boat moving, so having a solid structure to hang the power plant onto is key both for building and operating.
I have broken down the plan into three sheets, each 36 x 72 inches. In doing so, I was able to lay out the "chine shelf" template in full (as opposed to just one half on the smaller plans). I believe this is a great help as the most probable material for this build is plywood, and you now have the option to cut it out in one large piece directly from the template.
Below is a preview of the three sheets. The quality of this tiny image doesn't make it justice, but it should give you a good idea of what is included.
***Giant*** PT 109 Plans
1:16 scale in a single zip file.
Before you embark on this project, realize I have not built this boat and can only offer my experience from the much smaller 1:32 Pt boat. Having said that, I see no reason this much bigger PT boat couldn't be built in the same fashion, only with plywood instead of balsa.
So to give you a heads start, feel free to browse the build log of the smaller PT boat here:
Part One: PT 109 RC model - Background & build kick-off.
Part Two: Assemble the Hull structure.
Part Three: Planking the hull.
Part Four: Adding hatch coaming and deck.
Part Six: Building the Deck Houses.
Part Seven: Building the MG turrets.
