What IS the cost? $834, plus shipping a battery and charger. I think we’re talking under $950 overall and they have offered COPA members a 10% discount.

Does it do well pushing uphill? Mine works fine for a very minor uphill - grading for drainage. It seems to have plenty of power to spare. If the hill is pretty steep, the one weakness of the latching mechanism is that it uses rollers in front and behind the wheel to grab the tire. While this has never happened to me, I could imagine the nose wheel trying to jump over the rollers. The less weight on the nose wheel, the more likely. I would call them and ask. I have a friend who uses his to move a Cherokee 6 up a small ramp, 4" elevation over a 4’ to 6’ length, with no problems.
Does it go over lips at the front of hangers OK? I have no experience, but I think it will do as well as any unit in that regard. Traction is by one wheel, which you place your weight on to increase traction.
How much does it weigh? ??? I wouldn’t want to carry it if that’s an answer. I would guess about 30 lbs plus the battery. With the unit assembled, including the battery, it took two of us to load it into a truck at my house for the trip to the airport. This was as much due to bulk as it was dead weight.
It also has rollers at the front (away from the handle) which make it faster to move around without the airplane attached, than by using the electric motor. A nice feature that I don’t believe the others have.
I’ve seen the Power Tow and Aero Tow used on an SR22, and I like the Nose Dragger better only because the latching mechanism, which in my opinion is easier and almost a one hand operation. The tug which has a neutral and a fully adjustable speed control is the best for maneuvering the unit. The Nose Dragger has three speeds: forward, reverse and stop.
