I'm a noobe and after watching several LCI 6 point videos my question is why would you leave the back 4 levelers down while raising the front landing gear, wouldn't that put undue pressure on the back...
There is a mercury bubble level incorporated into the system. When you raise the front, the level changes and causes the back legs to retract as needed. So in answer to your question, raising the front does not increase the stress on the back legs.
