The control of the acrobee consists of the Flight Controller (FC), the Receiver that is built into the FC and the Transmitter (TX). In order for this system to work correctly all parts of the system must be working.
Example of Normal operation
Here is a video showing normal working condition. Please note each flying environment will yield different results but this shows a baseline.
Description of Problem
In this section we will take a look at having low control range.
This can be caused by a missing or damaged FC antenna, or physical damage to a part.
Some solutions to this are verifying the antenna is on the FC and about 31mm in length. Having either the internal antenna or external selection bridged. Also, make sure your transmitter has charged batteries.
If none of the above fixed your issue or if you press the bind button and the red LED does not blink quickly please open a ticket with your order number and a video showing the behavior.
