Hi Jim,
Question- why aren't you stabilizing the canards via Cortex? I recently purchased a Cortex with the intent of stabilizing the canards as well as the elevons and rudder. On my SM/Extreme Gripen, I am currently using a JR rate gyro for nose wheel steering and intend to keep it as such unless recommended otherwise.
Many thanks for posting your Gripen build on RCU with some GREAT info being presented. I'm closely following every post.
Rgds,
