We have provided below most of the common problems when preparing your plane for its first flight. 



Possible Solution

My motor spins the wrong way
Your motor should be spinning in the counter clockwise direction and producing noticeable thrust. If your prop is spinning clockwise, it’s very easy to fix. Simply swap any two of the motor wires over that are plugged in to the ESC.
One of my control surfaces is going in the wrong direction In most cases, the best way to resolve this problem is reversing the channel on your transmitter. Almost all transmitters provide this option in their menu. Simply locate the setting by consulting the user manual for your transmitter. 
I get a loud vibration when I throttle up The cause of this could be one of two common things:
Your propeller needs balancing
Please refer to this article on how to balance a propeller.
Your engine may be mounted a little loose
 Simply tighten the engine or look to re-glue it in place

I cannot connect my transmitter to my plane Assuming you have powered your plane and you have heard the typical beeps, you will need to ensure that you have binded your transmitter to your receiver correctly. Please consult your transmitter manual on binding your transmitter and plane.

My servo is making a strange sound

Some cheaper servos buzz when powered and still which is normal. However, if your servo is making a grinding sound when moving, it may be that the gears are damaged in some way. It’s best to replace a servo in these instances to avoid failure in the air. 

My motor seems slow and might not get me off the ground

In some cases you will need to calibtate the throttle on your receiver with the ESC. In most cases this is done by 

1. Remove your prop from your engine (this is important as the engine may spin up when performing the next steps and cause injury)

2. Turn your transmitter on and place it on full throttle

3. Plug the battery in to your plane and listen for a single beep (in most cases you will hear 1 beep). 

After hearing the beep, reduce the throttle to zero promptly and listen for a series of beeps

This should work for most transmitters and ESCs. If it doesn't work for you, you will need to consult the manual for your ESC. 


My plane makes a constant beeping sound when I connect my receiver and the motor will not spin

Please refer to the section above about calibrating your throttle and ESC. 

I have broken a part fo the plane's fusilage or wing, how can I repair it? 

Foam on a model aircraft is quite different to your typical foam. In most cases it's dense and can withstand a great deal of punishment. However, it may be that you have dropped the plane or crashed and need to re-attach the broken part.

Certain types of foam can react to glue by melting or warping. 
Make sure you test glue on a small area of your aircraft where damage may not be noticable. 

In most instances you can use two types of glue:

Epoxy Glue
This is a two part glue that cures in a set timeframe. Some set in as little as 5, 10. 15 0r 30 minutes.

Super Glue
This is also a popular solution for repairing aircraft.

I love all things that fly! I especially love learning and passing on any knowledge I have gained! Flying multicopters is my favorite thing to do. For me, it's just as much about the build as it is flying! I love to spend time in the garage tinkering with things and working out complex problems - my 3D printers being one of them...
