F405 Processing Power

ArduPlane VTOL Plane

There are some discussions over at RCG regarding the infamous Xiake VTOL. One very knowledgeable member Krazyman/Terry (probably a member here too) has brought up an interesting correlation between all his VTOL crashes and the use of F-405 based FC.

How much processing power is being used by Arduplane to run a VTOL plane? There is a CPU utilization indicator on Betaflight/iNav, and F405 seems to be able to run them with very low CPU utilization. With the complexity of Ardupilot could it really be exceeding the power of F405?

This is not correct. The 405 does just fine. I have several VTOL aircraft using the 405 and it is more than capable. I even run a 405 on a 10-pound QuadePlane with a Speedybee 405 wing with no issues.
