After getting the Maslow into 4.1 spec., I blindly grabbed the V1.0 firmware and installed it using the old methods. After reading the instructions I decided to regress to V0.88 and wait for the install video.
Calibration ran through a Fitness Too Low warning several times before completing with a fitness of 0.84445. Frame Flex was TLBR 4.115 and TRBL 3.422.
Are these numbers any good or should I look at reducing frame flex?
The firmware seemed to figure out the frame size pretty well. Using the hourglass frame, I set the extension length to an initial 2000.
