Something to watch out for. At least I've found it on mine. The landing gear wires tend to rust. Just enough that the wheels bind. Only took me 3 or 4 tries at taking off before I realized it wasn't the grass slowing her down. I think the skid mark from the nose wheel in the grass, is what caught my attention. Or maybe how it nosed down on roll out and wanted to nose over. DUH! Yeah trying to take off with the brakes locked on does tend to make flying speed a little harded to attain. Tried spit, even some oil off the van's dipstick, no joy. Had to drive home and remove the collars and wheels and sand the rust off.
Liberal amount of grease should hold up I hope.
