Now let’s get to the build. Step 1. - Glue the tail surfaces to the fuselage. Please ensure the tail surfaces fit flush and aligned to the fuselage, please make sure the fit is even and at the same level. Please dry fit these parts and make sure you are satisfied with the fit and alignment prior to gluing these surfaces. For this glue joint you can use a CA glue contact adhesive. Once this joint has been glued set it aside for the glue to cure.
Step 2. – Main wing Please use a servo tester or your Transmitter and bound receiver to check the servo alignment for your aileron servos. If by chance they are not adjusted correctly please adjust to suite. Using the supplied metal wing spar, please make sure you dry fit the spar with the left and right main wing sections to make sure they fit flush and you have the correct dihedral on the wing. Once you are happy with the fit please glue the main wing together with either CA glue or contact adhesive.
Step 3. – Main wing connection After the glued areas have cured now its time to attached the main wing to the fuselage. Connect the “Y-lead” servo extension to the left and right aileron servo leads. Please make sure you have connected this lead with the correct polarity. Attach the main wing to the fuselage by aligning the two plastic dowels keying them into position, then make sure your servo wire is pulled through the corresponding hole in the fuselage.
Step 5. – Model set up Your Durafly Bonanza is built and now you are ready to set up the model for it’s maiden flight. Using the correct battery we recommend a 1300 mah 3S Lipo battery (although you can use a battery from sizes ranging from 1100mah~2200mah.) Please for safety please remove the propeller and Bind your transmitter to your receiver, plug in the servo connections to the connection points on your receiver (please be mindful of polarity) Now connect your flight battery.
CoG The CoG is 80mm (+/- 5mm) from the front wing joint back to just in front of the main wing spar. please see image below. 80mm 80mm (+/- 5mm) Of course this is our recommendation you can adjust this CoG position to suite your flying style. Control throws – We suggest you set up the Durafly Bonanza with 10mm of distance from centre to maximum travel on all control surfaces. We also suggest you add 30% expo to the elevator control and 25% Expo to the Aileron and rudder controls.
FLYING TIPS Before you fly please check your controls and make sure you double check! Left is left, Right is right, up is up and down is down. With a v-tail please check the direction of the rudder and make sure left is left and right is right. Now you’re ready to “Throw it…” The Durafly Bonanza is a hand launched RC airplane, If you are unsure of hand launching your plane please find someone who can assist with launching your plane.
