Sure, many reasons:

BACKGROUND: All your planning flying any pylon-powered
toy must be around worst case: engine stuck out and not
running. Depending on the model, this can mean very
high sink rates, and badly degraded handling from
wake of pylon and radiator on tail.

The "motor out and not running" MOANR configuration
must be used to plan safety of take-off strip,
departure pattern, distance from airport, air-start
altitude and placement margins, etc.

Antares low-shutdown advantages:
- low sink rate and normal handling with MOANR
- only one control in cockpit to extend/retract
(unlike some which have VERY high workloads)
- normal handling under power makes it easy to
find and center first thermal
- no required cool-down cycle prior retraction
- ~10 second re-extension to power if I don't
climb after shutdown

All the above mean I can concentrate on finding
and centering the first thermal rather than
"engine management", with low stress. My average
shutdown is ~1000 feet, in locations where there
is lift near the launch and not too much traffic
(ie, Sterling, Hobbs, Uvalde). This leaves a very
substantial reserve for self-retrieve, though
this is certainly not a power XC cruiser.

Hope that helps !

PS: Someone needs to come up with a really good
and appropriately foul acronym for "motor out and
not running".
Boggs, you're on...
