The big secret is to stay at 80 MPH after takeoff until you've got the gear up. Push the release button, pull the collar down, swing the bar to the UP (floor) position rapidly, and push it briskly into the latch. The faster you're going, the harder it gets, and above 100 MPH it's just about impossible to get it into the UP latch. Ditto extending the gear. It's easy at about 100 MPH (the limit is 120).
JHjr is spot on
I used to fly one with this setup then moved to an M20J
These earlier systems were a handful and 80 MPH the trick as above that it got stiffer and stiffer to retract until impossible. Hold the nose up to maintain 80MPH retract then lower the nose to accelerate! You get used to it
