Fuselage jigs


We logged more than 125 hours on the Classic. The flight characteristics have been better than expected. The engine pulls the 1200 lb. flying weight alone very well. Stalls are docile with no bad tendencies. The ailerons are light and responsive, where as the Elevator is heavier and sensitive. We have changed the elevator horn to make this better.

The Front cockpit is comfortable with plenty of leg room, wind is light and visibility is good. The Back cockpit is a little different. First, viability is similar to a J-3 cub (flying from the back). Second, there is quite a bit more wind (similar to a Stearman). Third, at 6'2" I (Eric) am a little cramped, it's OK for shorter flights (45 min), but gets uncomfortable after an hour. We have lengthened the Fuselage 3" in the rear cockpit area to help this out. Also the Fuselage has been widened out by 3".

Weight and Balance: The CG limits are the same as the single seat, meaning the same position in relation to the wing. The front seat is just about over the center of gravity and has no effect to the CG. Fuel of course adds fwd CG and Baggage aft CG. The pilot sitting in the aft seat also effects the CG. If you build your airplane such that the empty weight CG is fwd (Having an electrical system, including battery located between the front seat rudder peddles, heavier engine like the Rotec R-2800, Continental O-200 or Lycoming O-235 or similar) you should have the ability to have a heavier aft seat Pilot (225+lbs) and Baggage (35 lbs.). By the same token, you can have a lighter engine like a Continental C-85, and will just have to install it further forward. With our airplane, to make absolutely sure we would be within range, we finish the airplane except for the firewall forward. Then I weighed the airplane and got my CG calculations. I then weighed the engine, cowling and all parts necessary for the engine compartment. With those figures I then started calculating were I needed to place the engine to be within range. All of this does take a little time but is not very hard to do. When you get to the point were you need to figure out were to put your engine, I will help.

 

Dual Controls: You can build your tandem with duel controls or not. Dual brakes are the most difficult to do so we did not fabricate them (it also keeps your passenger front getting on the brakes especially during landing). Front seat rudder peddles are installed with a cable attaching the front to rear. The stick is a little more challenging. The important thing to remember is that you need to keep the Geometry the same as the single seat. We built ours similar in design to Vans RV-4 design.

 

              


 

As can be seen it will accommodate two full size adults. Wings and Tail are silver and are ready for paint. Fitting wings for CG check

Fitting and installing the Rotec R-2800 and RUNNING. Very Smooth, Sounds just like a radial should. Look at video clip above

Some specs: Steel streamline landing gear, Rotec R 2800, Horizontal has a 1 foot longer span, 5/32" stainless flying wires, 3/16" stainless flying wires for the bottom of the wing, and 16 gals. of fuel.
