[TG] [TG11] Smartpilot S3

[unixdood]

Hi,
On the smartpilot S3 (non gyro) there is a decal stating it must be mounted vertical? is there a functional reason for this? Can it be mounted horizontal without any issues? Remember, this is the S3 non gyro version.
Thanks

Hello unixdood,

1. Heat dissipation. If you mount the unit flat, it can't effectively dissipate heat from those big drive FETS into the back plate and then away through convection. Instead it will collect hot air in the top of the plastic case.
2. Shock and vibration tolerance. The design and testing were with the unit in the intended orientation.
3. Water ingress. These pilots as drip-protected when mounted vertically, when mounted horizontally condensation and drips from above would be likely to collect around the connector panel.

Thanks for the reply Tom. Looks like i will have to fabricate a vertical mount. <sigh>
