Another version of a Senior Kadet,,

Inspired by the SAE DesignWest 2000 competetion held locally in June of 2000. Had to make one, only 40 years too late to qualify... (sob!)
The first cut used the first 'normal' Kadet Senior wing I built back in '95.. with ailerons.
A rectangular horizontal of the same area as the Senior.. built with geodetic ribs..and a normal Kadet vertical.
Nicely faired in engine, with the aft body made with two fiber-glass pushrods, suitably stiffened with diagonal bracing.. pull-pull rudder and elevator.
A seperate servo for the nosewheel to keep the cargo compartment clear of stuff that didn't need to be there..
Empty weight 8-1/2 pounds..
Level flight speed with 15 pounds of ballast measured at 80 mph.

Modified Kadet Senior

Latest form smaller empennage

The latest smaller vertical and horizontal..

et Senior inflight

The middle image in the photo shows the plane after building and flying several lifters made to the SAE spec. All-flying horizontal, 53% of the previous area as the major change.
The vertical area has been cut from 105 sq. in. to 72 sq. in.
This one was flown on March 14,2001 to see just how much weight a Kadet could be expected to carry. As the twins and the camcorder carrier spec'd out at about 12 pounds GW, more than this was expected. The plane lifted 15 pounds dead weight with an all-up TOGW of 23-1/2 pounds.
The takeoff run was just at 200 feet, with the initial climb rather slow. I feel this is about the limit the wing can carry with a .61 motor (K&B Twist head, 13x6 APC prop)

The interior layout:

The motor is mounted at 45 degrees to the right. This puts the exhaust mess underneath the wing, and the needle valve falls readily to hand. A 4 ounce tank has more than enough capacity for the short racetrack flight pattern.
A micro servo for the throttle, with an E-Z connector for fine adjusting of the end points.

All extension harnesses are secured next to the fuselage sides to keep the area for ballast clear of danglies..and each is identified at the receiver end.. throttle, steering, battery...all are harnessed together at the receiver end to keep them out of the way.

Elevator and rudder servos are close to the top in the wing opening for ease of access.

..Pull-pull rudder and elevator installation..

The nose wheel has its own seperate servo Y-d to the rudder servo, to keep the ballast area clear of pushrods, and for ease of alignment and maintenance.
The receiver battery is next to the tank and easily worked with, should it need any.
The receiver sits in a box underneath the servos.
The wing mounts with 5/16" dowels at the front, 1/4x20 nylon screws at the rear.
The aft fuselage structure is 5/16" dia. fiberglass rod, with spruce diagonal stiffening truss. It is VERY flexible, but doesn't wiggle around much in flight.
The receiver antenna runs thru the upper tube.. not a good thing to do if the tube is carbon-fiber..
