It's Finally Here!

Conceived in 2015 around a camp fire at an aerotowing event this has been a project 4 years in the making... This was a design consortium project among three of my friends spread out in the North East. They were looking for a robust, quality airplane with special details and features for the rigorous duties of towing up giant scale sailplanes. Thanks to Kevin Kremer, Jim Dolly & Len Buffinton

Though not 100% scale, it's built with a sport scale structure in mind. It has plug in wings with aluminum wing tube. Removable horizontal and vertical tail surfaces on carbon fiber tubes. Elevator servos in the stab. Rudder servo is in the tail cone which is also removable for easy access to the quick release linkage to the rudder. This model can be for scale Sunday flying, limited aerobatics or as a glider tow plane. This rugged Cessna is built tough and will deliver in all areas! That's why it's so popular as an Alaskan Bush Plane. Muddy runway... No problem!

It's all in the Details...

Attention to the finer details makes it a better model. You will find this in the cowls' front end; rolled inlet edge opening with molded in landing light pockets and carb. air inlet screen. Sturdy aluminum main gear and aluminum formed wing struts. Functional main doors with a locking latch (no screws to remove for opening) with magnets in the corners to prevent ratteling. Also a functional luggage door, great place for accessing your reciever switches etc. A semi scale aluminum tail wheel assembly that will take the abuse of full STOL landings. The floors' interior has pleny of room for all your recievers, batteries or even telemetry. It's a perforated floor system with plenty of slots for strapping your equipment down. Finally the lasr cut windshield with all the screw mounting holes laser drilled out too. And to compliment the windshield are the laser cut windshield frames. It looks Just That Much Better! Also the last detail provided is a pair of CG balancing jigs.

The Plans and Manual

We start out with a very detailed step by step full color laser printed manual wire bound. Pictures and text won't keep you guessing on this build. There is just over 1,000 pictures... more pictures than text. There are 7 sheets of rolled plans to build on; fin and rudder, stab and elevator, left and right wings. The fuselage is built flat over one sheet on your work surface while the side view sheet is 1/2 scale for your reference. Also provided is a Parts Sheet to help you find and locate the parts you need.

Whats in the kit

The kit is packaged and shipped in 3 boxes. 

Box #1 is the laser cut wood pieces; lite ply, thin birch ply & balsa. Also laser cut clear plastic PETG windows and front windshield with all the screw mounting holes laser drilled for you too. Also there is thin G-10 windshield frames and cardboard templates along with the construction manual. Plus 3 bags of metal, wood and hardware.

Box #2 is the CNC router cut parts from 3/16" to 3/8" thick birch aircraft ply along with G-10 control horns and main door hinges. Also in this box is all the stock lumber sheets and sticks. Topping off this box is your aluminum wing tube and carbon fiber tail tubes with sockets. Servo wire conduit tubes, aluminum wing struts cut to length with both ends coped at the correct angles. 7/32" dia. music wire bent tail gear along with a TIG welded aluminum tail gear assembly. Tail wheel included too. Finally a beefy 5/16" thk. water jet cut T6 aluminum main gear. Plus the rolled set of plans.

Box #3 is the one piece fiberglass cowl with landing light pockets and air intake molded into it.

Fuselage structure...

The fuselage builds up from your work bench over the plans. The four sides are from multiple pieces of lite ply with doublers up front, while the corners are 3/8" thick contest balsa sheets rounded over. The landing gear mounting structure is from thick CNC cut birch aircraft ply which is very beefy and not just attached to the fuselage sides but ties into the bottom of the main former at multiple points. Very Strong! The fire wall, engine box structure and the formers that surround it is also from CNC cut birch aircraft ply.

Tail structure...

The tail structures are built as one assembly at first to keep the control surfaces in perfect alignment and thickness with the parent surface. Build tabs and interlocking parts speeds up the build process. The tail is fully sheeted in 3/32" thick balsa skins. They are all easy removable with birch ply mounting tabs instead of the commonly used lite ply tabs that break off easily.

Wing structure...

The entire wing (inboard & outboard panels) is built as one unit. No more joining and gluing the inner & outer panels separately. Inboard panel builds directly flat on your work surface while the ribs on the outer panel have progressively longer build tabs on them as you move out to the tip including the set 1 1/4° washout. A laser cut "jack stand" supports the bottom spar into position. This "Thinking Out Of The Box" and new technique really simplifies, speeds up the construction and keeps things lighter and more accurate. "Brilliant!" Open structure with 1/8" balsa skins and cap strips.
