Since purchasing the Max from Inibuilds last year, I encountered repeated problems retracting the gear after takeoff. Inibuilds support wasn’t able to help me solve the problem, but then by accident I figured out a solution. I had been taking off at full throttle using my Logitech joy stick. Apparently, leaving the throttle at full after take off impedes retraction of the gear. By throttling back after V1 just a bit, the gear handles normally, whether operated using the mouse or key board. Hopefully this will help anyone else who might encounter this problem.
Moved to User Support Hub that is a more appropriate category.
To my knowledge, Inibuids has not developed a 737 max. Which developer are you referring to ?
