I've run into an issue installing the GSA 28 roll servo stop bracket and was wondering if anyone had come up with a solution. The stop bracket doesn't rest flush against the servo base due to interference with the servo mounting bracket. Reading through some older forum postings it seems that many builders have chosen not to install the stop bracket and rely on the primary aileron travel stops. It's not clear to me at this point in my build where the primary travel limiting system is located.
