Tech Tip / Installation Notice for Talon 90 and Talon HV120

If you are the owner of a Castle Talon 90 or Talon HV120 ESC  then this Tech Tip / Installation Notice is for you.

We have received reports of a small number ESCs failing in the field. After reviewing the failed units and their setups, we believe that we have found the cause. On certain applications, we have discovered that plugging the motor’s timing wires directly into the ESC can lead to a failure.

This can be caused by two factors:

One, the motor’s timing wires are inflexible and usually less than 3 inches in length. This makes it difficult to plug the motor’s male bullets into the ESCs female connectors. This can lead to damaging/bending the male connector, which in turn results in a loose and poor connection. As a result, this loose connection can potentially disconnect during use which can cause an immediate and catastrophic failure of the ESC.

NOT RECOMMENDED

The second potential issue is due to vibrations. Because the motor’s timing wires are stiff they have no slack or relief. Due to the extreme nature of some setups, the vibrations and the motor’s movement from torque can stress the female bullet connectors installed on the board and lead to a failure.

Castle highly recommends using 2 – 3 inches of appropriately sized silicone wire. The silicone wire (like the battery wires on the ESC) is quite flexible and provides some strain relief to the bullet connectors.

Below are two images from Helifreak user, “rotary guy” and a Talon 90 installed in a Goblin 500 helicopter. Note the extra lengths of wire between the connections and how this provides some post-installation flexibility, reducing the amount of “wire pulling” during flight while still maintaining a neat and tidy installation.

Talon HV120 and Castle Link Update

Talon 120HVIf you happen to be one of the owners of the new Talon HV120, you may see a strange pop-up window when trying to connect to the Castle Link. This is what it will look like.

The ESC is still fully programmable and works with 100% functionality on the Castle Link. This pop-up is simply informing you that firmware updates are disabled for the Talon HV120. This is because it is a new product line and there is currently only one firmware version available, hence, no updates.

Since you cannot select a different firmware version, the firmware update option has been temporarily disabled. However, when a new version of firmware is released for the Talon HV120, this notification will disappear.

We are currently working on adapting firmware version 4.20 to the Talon HV120. Version 4.20 is the same version current available for the Phoenix Edge and Phoenix Edge HV series ESCs. Once it is available, this update will allow the Talon HV120 to work on high pole count, high inductance out runner motors like the newer Hacker 28-pole out runners.
