All the Hovercrafts I know of use Gasoline power as their primary source of
renewable energy. Check to see if your Edge has solid or air filled
tires. That could make the difference. Center powered wheels offer some
great
options to its uses. However climbing a steep portable ramp is not one of
those great options. As the front castors reach a given angle, they have
been known to lift the center drive wheels off the ground making them less
effective. Also,
The Pride Edge wheelchair is part of the Quantum Division and narrows those
who can work on repairs and mods on your chair. Not every Pride
Dealer/Provider is Quantum Certified/Qualified. The Edge is relatively new in
the
market, so I'm sure their is more good stuff, then negative. Programming
is so difficult that reprogramming often costs more, should you have
software issues. Lastly, watch out for water and heavy moisture.
