[edit] Known issues
The tail belt can cause a static electricity discharge, which can reset the flight electronics and cause temporary loss of control. A number of methods, including grounding the boom and tail belt to the battery 0V, or spraying the belt regularly with silicone grease, are believed to mitigate this issue. The Torque Tube version does not have this problem.
[edit] Hints and tips
There are reports that replacing the standard flybar with the one for the Align T-Rex 600 increases the helicopter's stability significantly, due to its extra length.
A few people have converted their 500 to run off nitro, typically using an 15-35 sized engine. Conversion kits are becoming available, see below.
