❑ RADIO SYSTEM The KADET SENIOR ARF requires a standard 4-channel radio system and five standard servos. In addition, you'll need two 12" long Servo Extension Chords (actual length needed will depend on how long the wires are coming off your servos - be sure to double check your servos and plan accordingly), and one standard YHarness Chord for connection of the two aileron servos to the receiver.
power for load carrying chores and more aerobatic performance. Also, the motor you choose should be rated at 500-800 KV, in order to turn an appropriate size propeller. Another good measure of brushless electric motors is the common 7-digit system of actual motor dimensions, followed by a hyphen, followed by the KV rating. ❑ PROPELLER FOR ELECTRIC With electric powered models there are many factors that have a bearing on what propeller to use.

Once your iron is set to the correct temperature, go over the entire framework of the airplane, making sure that the covering is securely bonded to the structure everywhere the covering comes in contact with the wood underneath. This takes some time, but is worth the effort.
c) Adjust the aileron so that the tip of the aileron is flush with the wing tip. The ailerons should be tight against the pins in the hinges to minimize the gap between the wing and the aileron. The aileron is now in the proper position for permanently gluing them in place with thin CA glue. d) Flex the aileron down and hold it in this position. Remove the pins from one hinge and then carefully apply 3-4 drops of Thin CA glue directly onto the hinge in the gap.
Pin. Then test fit the wing assembly on the fuselage. The tab that is formed by the two panels at the center, leading edge, fits into the cutout in the front fuselage former. At the rear, two M6.5 x 30mm nylon wing bolts secure the wing to the fuselage. If you encounter any difficulties mounting the wing to the fuselage, find the problem and fix it now. Then remove the wing from the fuselage and set it aside. Metal R/C Clevis.
axle and test to make sure it spins freely. If it does not turn freely, drill out the plastic hub of the wheel with an 11/64" or #17 drill bit. TAIL SURFACE & TAILWHEEL INSTALLATION For the following steps you will need: (1) Fuselage (1) Wing (1) Stabilizer & Elevator set (1) Vertical Fin & Rudder Set (2) M6.5 Nylon Wing Bolts (1) Tailwheel Assembly (2) M3 x 12 mm Screws (2) Nylon Control Horns with Retaining Plates (6) M2 x 14 mm Screws ❑ 9) Slide a second wheel collar onto the axle and up to the wheel.
glue is applied in the next step. You can now remove the pins and take the stabilizer off the fuselage for gluing. c) Keep sliding the wire in until the short top leg exits the slot in the stabilizer. ❑ 14) The horizontal stabilizer can now be glued permanently onto the rear of the fuselage. We suggest using slow drying epoxy glue for this job to allow time to position the stab accurately and make any final adjustments that might be needed. Apply the glue to both sides and reset the stab in place.
e) Finish the rudder installation by gluing the CA Hinges in place with Thin CA, using the same techniques you did for the aileron hinges back in Step 2. f) After all the glue is dry, adjust the wheel collar to sit snug against the bottom of the nylon tailwheel bearing. The purpose of the wheel collar is to keep any loads from the tailwheel from putting stress on the rudder.
clevis can’t open up and come loose from the control horn by sliding the small piece of fuel tubing over the arms of the clevis. Also tighten the M2 Hex Nut up against the back of the clevis Elevator servo shown - proceedure is the same for the Rudder servo. ❑ 25) Locate the pushrod exit hole for the elevator inside the rear of the fuselage and repeat step 24) in its entirety to install the elevator pushrod.
❑ 27) NOTE: The mounting of the electric motor in the KADET SENIOR assumes that your motor has a typical "X" or "cross" mounting plate on the back of the motor. and drill out the mounting holes with a 7/32" dia. drill. Install four M4 Blind Nuts in the holes, on the back side of the firewall. Put a couple drops of glue on the flanges of the blind nuts to secure them to the plywood. Be careful not to get any of the glue in the threads.
b) Decide on a good location for the ESC in the nose of the airplane. The most likely location is against the fuselage side, out of the way of the battery pack. Mount it to the airplane structure using a method of your choice - like double-sided tape or Velcro® (neither of these are provided). c) Now route the ESC’s servo wire back to the receiver and plug it in. d) Connect the ESC's motor wires to the motor. Operate the motor and check the direction of rotation.
for either 2-stroke or 4-stroke power plants is basically the same. The main difference is often times the throttle arm location on the carburetor. The materials provided in this kit should be useful for almost any 2-stroke engine installation. Installation of a 4-stroke engine may require some alterations and/or specialized fittings (not supplied).
c) Once you are satisfied with the fit of both the fuel clunk line and the vent line you can tighten the screw to expand the rubber stopper and seal the stopper in the tank. Do not over tighten the screw as it can cause the tank to split. Attach three 6-inch lengths of silicone fuel tubing (not furnished) to the tank and label them appropriately as FILL, CARB, and VENT so you can identify them after the tank is installed in the airplane.
to come out the vent line! Re-connect the fuel lines and you are ready to start the engine. sliding it back until approximately 1/2" of the nylon tube remains in front of the firewall. f) Now slip the plain end of the pushrod wire inside the pushrod keeper. Clip the metal RC clevis onto the servo arm and set the servo in the middle of its travel. Set the carb in the middle of its travel, and then tighten the set screw in the end of the pushrod keeper.
velope a pattern and mark it on the cowling for guidance when you are cutting. a) Begin by marking a centerline on the top of the cowl. screw. Recheck the overall fit of the cowl and make any adjustments needed with tape to hold it in place. Then on the opposite side of the fuselage, drill another 1/16" guide hole and install a screw into that hole. Repeat this process for the remaining two cowl mounting holes. Remove the tape.
CONGRATULATIONS! CONTROL SURFACE TRAVEL Your KADET SENIOR is completely assembled. However, it is NOT ready for flight! There are a few very critical pre-flight tasks we must perform before flying. These are extremely important and should be approached with patience and care. Double check the alignment and movement of all the controls one more time! Adjust all of your pushrod linkages so that the control surfaces are in their neutral position when the transmitter sticks and trim levers are centered.
trols for the first time. Let the instructor get the model airborne and flying straight and level at a safe attitude (“several mistakes high” as the old saying goes) before he turns the transmitter over to you. You will quickly find out that it is very easy to over control an R/C model and to get disoriented - EVERYONE DOES IT AT FIRST! If you get out of control on your first flight, quickly hand the transmitter back to your instructor so he can rescue the airplane.
