Greetings Gary. I have one for my F33A, and it works quite well. Moves the airplane up a slight slope and over a 3/4" concrete lip when placing the aircraft back in the hanger easily. I did buy an extra battery so I always have a fully charged unit ready to go. Key is to make sure you hold adequate downward tension on the nose wheel tire when using. Too little tension and the metal drum will spin on the tire and can eventually lead to increased tread wear. I have had for a year and my nose wheel tire is none the worse for wear. I can also fold it up and place in the baggage area if I think I will need on a trip. Not a bad unit at all for the price point.
Hope this helps/G
