HPI products are different from Castle products. They are HPI products made to their specs, we just happen to manufacture it. HPI requires approval from them for all firmware changes and updates; they do their own testing and have to tell us to update their products. The rules that apply for a Castle ESC do not apply to an HPI ESC. We do not control whether or not you can roll back to older firmware versions after updating to the new version.

It is an HPI product, covered by the HPI warranty and support. If you have a problem with an HPI product, you need to contact them with any issues, complaints or concerns. If you cannot roll back the firmware on the ESC and the new firmware does not work correctly then unfortunately there is no way to fix the problem without sending the ESC into HPI for repair/replacement. If you are unwilling or unable to send it in, there is not way to get it working again until a new firmware version is released to fix the issue.

If HPI identifies that the new firmware has a problem they will come to us and we will work on a solution. Until a new firmware is released -which there is no way to give any type of time frame on a release- there is no solution to the issue.
