In other words, you need to build your plane correctly and understand the forces that act on it in flight. If you've bought an RTF or ARF plane all the construction work has been done for you, but you should still check it over to check for good and correct alignment of wings and tail surfaces.
Poorly aligned, bent or twisted surfaces will only result in a poorly performing plane. If you're building from a kit or from scratch, you need to take care when building and be sure that there are no warps, bends or twists where there shouldn't be. Any of these will have a very negative effect on your airplane's flight characteristics. Assuming that your plane is correctly built and has everything aligned correctly, it should fly perfectly first time out, right??
RC planes rarely fly perfectly, the best we can ever hope for is that a couple of clicks of transmitter trim will sort things out on its maiden flight. But what if your rc plane flies really badly, yet it's been built well?
This all might sound very technical and complicated, but it's really not and once you've done it once, and seen the results, you'll want to do it to all your planes. You can read about balancing rc airplanes through that link, but just to recap, the CG is the point at which your plane balances fore-aft longitudinally. This means that when your plane is supported on its CG position and is balanced correctly, it will balance level or perhaps with its nose pointing down slightly. RC planes rarely have one exact point of balance; the acceptable CG usually lies within a narrow range, and the precise location of the Centre of Gravity can be moved within this range, without having any adverse effects on the plane's flight characteristics.
It's only when you move the CG outside of its range do the problems begin. This moving of the CG fore or aft, within its range, is a major part of correctly trimming your rc airplane. Any movement of the CG will slightly effect your plane's pitch attitude, elevator sensitivity and how it wants to fly as a result.
If you move the CG forward then this increases the plane's stability up to a point and generally makes it less sensitive to elevator inputs. Conversely, moving the CG rearwards increases the sensitivity to elevator inputs and makes the plane less stable - but better for aerobatics. Moving the CG too far rearwards will make the plane completely uncontrollable.
It also allows the trim and mixing functions to work properly. TIP: Remember, especially on a 3d setup, full rates are only used when flying very slow and near stall speed or when doing violent tumbling. When flying straight lines or general aerobatic flight, stick movements stay close to the center.
As long as the high rates feel good near the center, take off, landing and general flying can be done on high rates. People often fear the high rates because of extra sensitivity. That's why it is important to get a ESC with an amperage rating higher than your motor or your motor will pull too many amps through the ESC and cause the ESC to overheat and possible catch fire.
Then you risk a fire and burning up your RC plane! That would be horrible! Then your plane would go down in flames onto your neighbors hay barn, catch that on fire, then a the fire starts spreading. I'm just kidding, well about it burning everything up part :D. Batteries have several different characteristics. The first thing to talk about is the battery's voltage. While the batteries exact voltage may not be printed on the battery itself but it will tell how many cells the battery has.
LiPo batteries are made up of cells. Each cell is 3. This means that is has 2 cells, which would give it a total voltage of 7. These cells fully discharged should NOT go below 3. So for a 3S battery fresh off the charger it will be about You can drain that battery all the way down to The less you drain the battery the better.
The next thing is the Amp capacity. The battery shown above is a Mah battery. This means the battery can supply milliamps over a 1-hour period. Finally there is the discharge rate. This particular battery has a 25c discharge rate. This is how much current the battery is able to supply. The higher the discharge rate, the more power you will get from your battery.
In order to see how much current your battery can deliver, multiply the C rating by the capacity of the battery in amps. For instance the battery shown above is a 2. This means during it's lifetime This is plenty enough to power any foamboard planes.
You motor is the power plant of your plane. The motor will turn your propeller at a high speed to propel it through the air! The standard motor that you put in your RC plane is brushless, which means it runs off of AC current.
This is why you need a speed controller to convert the battery's DC power into AC. When choosing a motor there are two basic things you need to look for. The motor above runs at KV. KV means that for every volt applied motor will spin times. If we use a 2s battery 7. Power rating. The motor below is 52 watts. In order to find the wattage of the motor multiply the max current of the motor by the voltage applied to it. This motor pulls 7 amps and uses a 2s battery 7.
Servos are what move your control surfaces. The servos plug into the receiver. The ailerons plug into channel 1 on the receiver and the elevator plugs into channel 2 on your receiver.
When you get your speed controller it will not have all the connectors necessary to hook everything up so you will need to pull out your soldering iron and heat shrink and get to work! The speed controller hooks up to three things, the motor, the battery, and the receiver. With that in mind. First find out what type of battery connector is on your battery. The type of plug that was on the battery shown above was an XT60 type. You can 'half plug' the two connectors together and make sure that the red and black wires match.
Make sure to cover any exposed wires with heat shrink. Now you need to add the connectors that go to the motor. On the specifications for your motor it should tell you what type of connetors are on. For instance, the motor shown above comes with 3. In order to connect this to the ESC, you will need 3x 3. Do NOT get a plane with a symmetric airfoil curved on the top and bottom of main wing when viewed from the side —this plane will be aerobatic and not able to fly as slowly.
Note: the Bixler v1. Hawk Sky Videos:. Bixler Videos:. However, if you want to go the economical route, just use the included basic charger that comes with the Bixler v1. If you buy the Bixler v1. If I am not mistaken, hobbypartz. Look out for that. Bixler v1. If the one above on ebay is sold out, search around to find an alternate that has those specifications above. It is extremely useful for securing your batteries to your plane, or even electronics, speed controllers, receivers, etc.
I gave him some of mine and he was impressed. If the glue ever gets jammed has happened a few times after being on high heat for very long periods of time , pull the glue stick out, pull off the melted portion that may be getting stuck in the gun, re-insert glue stick, and continue use.
