When the extension connector is pulled through and out of the hole pull the rest of the lead assembly out of the hole while fitting the aileron hatch in place into the opening at the outer end of the panel Repeat this process to route the servo extension lead and to seat the aileron servo mount hatch in the opposite wing panel Temporarily tape the loose aileron extension leads to their respective wing panels The two aileron servo hatch mounts can now be secured to each wing panel with the screws removed earlier Q 11 As shown the aileron control horns are positioned 3 out from the inboard end of the aileron to the vertical arm on the control horn Mark the two mounting hole locations for the control horn screws onto the surface of the aileron Use a 1 16 dia bit to drill two holes at the marks just made approximately 1 2 deep Mount the control horn to the aileron using two T2 x 12 mm PWA screws Repeat this process on the opposite aileron O 12 From the kit contents locate the two 2 6 mm dia x 55 mm aileron pushrods with R C links and lock nuts on each end Note that as shown we use short lengths of fuel tubing over each R C link to hold them firmly in place and suggest you do the same thing Clamp the trailing edge of both ailerons in the neutral position to the wing panels as shown Again connect the two servo leads to the Y harness and plug the harness into the aileron receptacle in your receiver Turn yo2. JORITA SIR p READY To FLY SIG MANUFACTURING 5 COMPANY I INC gt AAA A A A DB XN KADET ENIORITA EP ALtmosr Reavy To FLY un D ul S KADET SENIORITA EP ARF ASSEMBLY MANUAL INTRODUCTION Congratulations on your purchase of the new SIG KADET SENIORITA EP ARF kit The Kadet Seniorita was originally designed by Claude McCullough following the same guidelines as it s larger brother the Kadet Senior but in a more manageable size Claude put a great deal of thought into the Senior design and came up with an R C training aircraft that was just about perfect Since it s introduction in 1987 the Kadet Seniorita became one of the favorite trainers for thousands with its low wing loading and slow flight characteristics As proof it s safe to say that in the following years the Kadet Senior and Seniorita have been used to train thousands of modelers to fly In addition these designs have been used for many other applications as well as being kit bashed into any number of different configurations The Kadet Seniorita kit is still in production and remains a true model aviation classic Over the years we have received many requests to equip the Kadet Senior with ailerons something we did with the ARF version Now we have also added ailerons to the Kadet Seniorita EP ARF kit making it all that much more usable in the training role it was designed for In addition we have designed th
3. allowing the model to be viewed accurately from either the front or rear Support the bottom rear of the fuselage with blocks magazines etc With the fuselage now in this position place the stabilizer onto the top rear of the fuselage and center it Place a small weight onto the center of the stabilizer to hold it in place Now view the model from the front or rear at a distance of 10 feet or so The stabilizer should be squarely in place without tilting to one side or the other In the unlikely event that the stabilizer is tilted remove it from the fuselage and use a sanding block to sand the fuselage stabilizer saddle on the high side to remedy the tilt dA 7 Remove the stabilizer and mix a small amount of epoxy glue Apply glue to the fuselage stabilizer saddle and also apply a thin coat of glue to the bottom center of the stabilizer Carefully place the stabilizer back on the fuselage as squarely aligned as possible and hold it in place with a small weight Using a yardstick make sure the stabilizer is sguare with the fuselage by measuring from the trailing edge of the wing back to the leading edge tip of the stabilizer on each side Shift the stabilizer as needed to achieve the same measurement on each side Any excess epoxy glue can be easily removed with a paper towel and a little rubbing alcohol before the glue cures Allow this assembly to fully cure O 8 The vertical fin and rudder assembly is now glued in place to
4. sure the throttle stick is in the full low throttle position Now plug the flight battery into the ESC and secure the battery hatch Test the controls to confirm that left is left right is right and up is up Taxi the model out to the center of the runway lining it up with the center of the runway with the nose facing directly into the wind Advance the throttle smoothly do not slam it wide open all at once to get the model rolling forward Make small rudder nose wheel corrections as needed to keep the airplane pointed straight down the middle of the runway As speed builds and the airplane becomes light it is at flying speed Smoothly apply a little up elevator for lift off Keep the wings level with small aileron corrections and continue a shallow climb to altitude Once the airplane is about 100 or more in the air throttle back to a reasonable cruising speed and begin making any required trim corrections with the transmitter The goal is to trim the airplane for hands off level flight at cruising speed Note that like most trainer type aircraft using a flat bottom airfoil section the Seniorita EP ARF will tend to climb under full power This is perfectly normal and is what makes the airplane want to return to stable flight if upset Many full scale pilots use this characteristic to control altitude using just the throttle Because of its large high lift wing the Seniorita EP ARF is capable of maintaining level flight at very low air

18. blem for beginners is disorientation For example when the airplane is flying away from you right aileron input produces a right turn and left aileron produces a left turn However when the airplane is flying directly towards you the same right aileron makes the airplane appear to turn left This perceived reversal is very confusing to all first time R C pilots Without an experienced flight instructor on hand it will most likely cause the loss of the model With a flight instructor these early learning problems can be easily dealt with The more you fly the quicker you will learn You will soon solo and begin to really enjoy your model Remember the first time you tried to ride a bicycle It seemed completely awkward the first time but once you learned how it became easy Don t be discouraged if you have a minor crack up Just repair the damage and get back in the air as soon as possible PRE FLIGHT Before heading to the flying field be sure your transmitter and airplane batteries are fully charged We suggest that you create a simple checklist of those items that you will need to take to the flying field such as the transmitter all appropriate tools fast charger for the airplane battery pack cleaning solution rags or paper towels flying cap sun glasses etc Ask your instructor to completely inspect your airplane to make sure it is flight worthy This little bit of insurance can go a long way in making your airplane la
19. craft instructor There are hundreds of R C clubs in the U S and these clubs typically have designated instructors who are eager to help newcomers The easiest way to find an R C flying club is to ask your local hobby shop or check the AMA Academy of Model Aeronautics web site www modelaircraft org Also be aware that the Kadet Seniorita EP ARF is a large airplane requiring an appropriate amount of runway This airplane should NEVER be flown in backyards parks or within five miles of an AMA sanctioned radio control model flying site This simple precaution can prevent the loss of your model from radio interference Do yourself a favor and join your local R C club You will almost always get assistance and good advice and you might even make a new friend or two An R C flight instructor serves two important functions First he will test fly your new airplane to make sure it is performing correctly before you try to fly it These first flights are called trim flights During these flights the flight instructor will trim the model from the transmitter to ensure that it flies straight and level without any problems When a brand new R C model takes off for the first time there is no way of knowing which way it might want to go Some models will try to climb while others might want to go down Some will try to turn left some right Some models will be doing both at the same time It doesn t mean that there is anything wrong with the
