Aerobeez 65″ 20cc Extra 330sc Manual
Hello to all you pilots and builders, welcome to our official Step by Step build guide and manual for our Aerobeez 65″ 20cc Extra 330sc! This manual will walk you through the steps to building our Extra 330 Profile ARF Kit. This Extra Profile will be built around the DLE-20 engine. Please take note that the build steps are that of our pilot Orel “Jazzy Hands” Elbaz. When building a profile ARF, there are several variations that can be taken. The variable choices include: your engine choice and the side to mount your ignition / fuel tank. There is no real set method, just personal preference. Use your best judgment to see how the fuel tank and ignition placement will fit best for your engine configuration. Also with profile builds, the covering on the fuselage will need to be cut away in several areas to route wires, etc. Do NOT start cutting all the covering away at the same time. Cut the covering for the area you are working on then move on to the next step. We suggest doing this so that you do not cut away an area that was not needed to be cut.
It is recommended that you read the instruction manual BEFORE beginning the build in order to get an idea of what is needed and the steps that we recommend be taken.
Needed for this build:
#11 Hobby Knife, 20 min. epoxy, Thin CA, Medium CA, Acetone, and the Aerobeez 65″ 20cc Extra 330sc
This plane is equiped with a DLE-20cc on a Xoar 16×8 propeller and we are running Hitec Hs-7954sh all around and a Hs-5665mh on throttle with a single 2550 2s Pulse Rx and Ignition pack. For this build we used our Miracle 1.5″ servo arms.
Now let’s start the build!
First we will begin by installing landing gear. Locate you carbon fiber landing gear, wheels, hardware bag, and wheel pants. (Note:In this picture I do not have wheel pants.)
Next install your axle onto your landing gear. The order should be nut, washer, carbon fiber landing gear, wheel pant, white plastic washer, wheel, collar. (Note: REMEMBER TO USE LOCTITE!)
Next cut out the landing gear holes in fuse and install landing gear. Remember to use loctite!
Tail wheel assembly is already installed so just screw into center of the tail. (Note: I recommend to remove all screws and apply loctite.)
Next we will begin hinging the wings. Locate your ailerons, carbon fiber control horn, and hinges.
I recommend that you take some sand paper and scuff up both sides of the horn.
Now you will cut out the slot for the horn on the aileron
Now put some epoxy on the horn and in the slot. (Note: CA can be used as well but I prefer epoxy.)
Now you can install you horn and wipe off the excess epoxy with paper towel. (Note: I like to wet the paper towel with Acetone, I have tried many things in the past but I found that nothing removes epoxy like Acetone.)
Next we will install our hinges. I like to prepare by rubbing the knuckles of the hinges with some Vaseline to keep the epoxy from sticking.
(Note: If this is your fist time I recommend using 20 min. Epoxy to give you time to make adjustments)
Now you can open up the holes on the wing and ailerons with a #11 blade.
Then you can put some epoxy on your hinge and inside the holes and install your hinges to both surfaces and push together.
(Note: Use Acetone to clean the excess epoxy from the hinge line.)
Now locate your wing brackets and install you your wing
(Note: Use loctite!)
Use the same techniques to hinge the elevator.
(Note: Do NOT hinge the rudder yet!)
Next take a small handsaw or a razor blade and remove this part of the tail.
(Note: Do NOT throw this piece away, you will need it!)
Now place your elevator in this slot and measure both sides to make sure it is centered and mark it with a pen.
Using a sharp #11 blade remove the layer of Oracover reveling the wood on both sides.
Now place the elevator back in the slot and glue with Thin CA on all sides then go over again with Medium CA.
Now go ahead and install the piece of wood we cut out using some CA
Now to add some extra security I decided to drill one inch under were the existing last hinge hole was and place the hinge in that new area.
(Note: This step is not mandatory, but it is recommended.)
Now using the same steps as before hinge the rudder.
(Note: Do not install rudder horn yet.)
Now finish installing tail wheel.
Next we can cut out these hole in the fuselage.
Cut out your desired tail servo location.
(NOTE: The rudder servo placement is under the elevator and the elevator servo location is in front of the elevator)
Take a long push-rod and fish out your servo wires to the fuse holes we cut out.
Now go ahead and cut out your aileron servo holes on the wing and install the servos.
Once the aileron servos are mounted, cut out your access holes on both wings and install doors with the four wood screws supplied in kit.
Now you may install servo arms and push-rods.
(Note: Don’t forget to loctite the push-rod screws.)
Now we can install your rudder servo horn. There is no rudder servo horn mount, it is mounted on the bottom of a stringer in your rudder.
(Note: Press rudder against stringer as it is drying to insure a tight strong bond. I recommend using Epoxy for this.)
Now you may install your throttle servo.
Next install your motor.
(VERY IMPORTANT NOTE: Use RED loctite when installing motor.)
Now you may connect your throttle servo to you motor.
Next locate and install your fuel tank.
Now you can cut out the four little holes in the front of the plane. Once the holes are cut, use velcro and the zip-ties supplied in the kit to mount your fuel tank.
Now you can place your receiver in side the access panel on your wing and plug in all servos into your receiver.
On the opposite side, use strong velcro to mount and install your battery.
Cut out hole for your switch at the desired location.
Finally, install the propeller and ignition.
Set your control surface throws to your flying preference. Range test your radio system and test CG. For CG on this ARF measure the CG from the leading edge of wing root rib. Adjust the battery pack location. For CG proper position should be at 27% MAC. This recommendation balance point is for your first flights. The CG can be moved around later to fit your personal taste. If you are not comfortable with the calculus involved you can use this online CG Calculator. Just plug in the simple measurements and the app does the calculus.
Note: Use Diagram below as a reference for manual calculation.
NOTE: CG can vary depending on flying style, set-up, and electronics, so do not be afraid to play within a small range of the suggested starting point until you find what works best for you.
Now you are ready to fly!
