FINAL ASSEMBLY / CONTROL THROWS & BALANCINGControl ThrowsThese control throws are merely a starting point foryour radio setup and can be tailored to fit your flyingstyle.1/2"Aileron-Low Rate1/2"2.Check the direction of travel of your controlsurfaces and the operation of the motor controllerper the manufacturers instructions.3.Range check your radio system per themanufacturers instructions.4. Double check that you have installed the screws inthe servo control arms and that the clevis aresnapped tightly on the control horns.BalanceAileron-High RateElevator-Low RateElevator-High Rate3/4"3/4"1/2"1/2"3/4"3/4"We strongly recommend that you get help from anexperienced R/C pilot to learn to fly if you are justbeginning. You should be able to find help at yourlocal dealer or club field.<strong>Fly</strong>ing Your E-HawkFirst of all, if you are flying with other flyers, check tomake sure they are not operating on the samefrequency as you. If they are, do not turn on yourradio until they have safely landed and have turnedtheir radios off.Secondly, even though the E-Hawk is very easy to fly,if you are a novice modeler/pilot, we highlyrecommend that you seek the help of an experiencedmodeler for your first few flights. He can save you alot time and possible disappointment by helping youget your model in the air safely and getting it trimmedout for you.50.Balancing your model is very important and mustnot be overlooked. The center of gravity (CG) is2 3/4" behind the leading edge of the wing nearthe wing root, parallel with the fuselage. You canadjust the battery pack forward or backward toreach the right CG.70mmFIRST FLIGHTS2 3/4" (Checks You Should MakeBefore you attempt to fly your model you shouldperform some final checks:1. Fully charge your radio and flight batteries followingImportant: The radio control system is set up tooperate the control surfaces just like a real airplanesas if the pilot (you) are sitting in cockpit controlling theairplane. When you want the plane to dive, you pushthe elevator stick forward (up), to climb you pull thestick back (down), to turn right, you move the aileronstick to right with elevator up and visa versa. Whenyou want to turn the motor on you push the throttlestick forward and when you want to turn the motor offyou pull the stick back. It is the turning that causesthe most problems with novice pilots because whenthe plane is flying towards you a right turn commandon the transmitter cause the plane to turn to your left(which is the planes right). Get the picture?Fortunately the up and down commands do notchange. The easiest way to conquer this problem isto try and always face your body near the direction theplanes is flying. This means that you will have to lookover your shoulder at times, but many modelers findthis an easy way to learn.
THE FIRST FLIGHTSYou should always use the first few flights to getaccustomed to your new airplane and its flyingcharacteristics. Keep the model upwind and climb toa good comfortable altitude to cut off the motor andtrim your E-Hawk for a glide. At altitude cut the motorand start your glide. Have an experienced modeleradjust the trims of the transmitter for you until theplane will glide straight and level without any othercontrol input. Once the trims are set practice makingsmooth turns in both directions while losing as littlealtitude as possible. When the E-Hawk starts to gettoo low for comfort turn the motor back on and climbback up to altitude. Practice this climbing and glidinguntil you are comfortable with the airplane.Depending on the battery you use the E-Hawk willmake 2 to 3 good climbs up to a nice thermalsearching altitude from single battery charge. Oncethe Auto Cut-off Device or ESC shuts off the power tothe motor you will need to set up for your landing.Continue to make smooth gently turns while lining upthe E-Hawk with your landing strip. Once you are setup to land keep the wings level and let the modelsettle in for an nice gentle landing while adding upelevator to keep the nose up slightly as the planeslows down. Make several flights like this to reallyfamiliarize yourself with the characteristics of yourmodel and to learn the glide and distance coveringabilities of the E-Hawk. Once you have mastered agood “comfort level” you are ready to start searchingfor thermals which will really increase your flight times.THERMALSThermal soaring is one of the most interesting andchallenging types of flying there is. Believe it or not,your E-Hawk is capable of flights thousands of feethigh, lasting for several hours, and covering dozens ofmiles. The following paragraphs will help explain howto take advantage of natures energy sources calledthermals.“Thermal” is the term applied to columns of rising air.This air is rising because it is warmer than thesurrounding air. A dust devil is simply a thermal whichahs picked up some dust. Even a tornado is verysimilar to a thermal, but of course much stronger.Thermals occur when the sun, or other heat source,heat the air in one location faster and/or warmer thanthe surrounding air. Darker surfaces (plowed fields,asphalt parking lots, etc.) absorb the sun’s energyfaster than lighter colored and are generally goodthermal generators. This warmer air is lighter (lessdense) than the cooler air and thus rises. The risingair naturally starts to rotate, much like water goingdown a drain, and forms an inverted funnel shapedcolumn that usually gets larger with altitude. Thiswarmer air often contains water vapor whichcondenses as it reaches the cooler air high above theearth forming big puffy Cumulus clouds thatexperienced sailplane flyers will watch to determinewhere the thermals are forming. Thermals vary instrength, but often contain air that is rising at speedsover 1200 feet per minute. Some thermals are sostrong they can even rip a sailplane apart, especiallyif the plane is flying fast when it passes through thethermal.THERMAL SOARINGIt takes lots of practice and concentration to thermalsoar like the Hawks and Eagles. Since the pilot is notsitting inside an model sailplane, he cannot feel thethermal, he can only see his sailplanes reaction to thethermal. Therefore, the majority of the time, unlessthe pilot is paying careful attention to the plane, hemay not even realize that plane is near a thermal.Since most thermals are relatively small, less than ahundred feet in diameter near the ground, thesailplane will rarely fly directly into the thermal andstart rising. More likely, it will fly near a thermal andthe wing closest to the thermal will rise turning theplane away from the thermal. So as you can see, aninexperienced pilot may bounce around between thethermals with ever knowing that he is encounteringrising air.In order to take advantage of thermals, you need to flysmoothly with as few control inputs as possible.Watch the sailplane carefully and it will tell you whatthe air around it is doing.When a sailplane does fly directly into a thermal it willeither start rising or stop sinking at its normal rate.Either case is reason enough to explore further.Continue flying straight ahead until you haveobviously passed through the area of strongest lift.Now start circling in fairly tight, but smooth circles.Because of the thermals inverted funnel shape, thelower the planes altitude, the tighter the circles needto be. As the plane gains altitude, the diameter of thecircles can be increased. If you see the plane falling
