Hi Shane,
Provided you are happy with the weight these should be perfect.
They offer a lot of advantages over others inc,, lipo's.
In that application up to 2000 cycles.
They are ok with being completely discharged (eg; if you forgot to turn off rx). If you do this once with lipo its a bin job.
NO FIRE HAZARD AT ALL.
Can withstand substantial physical abuse ,they've punctured them with nails in testing ;no fires!!.
Can be zip charged 5 to 10c.
30C continuous discharge, would survive just about anything imaginable servo failure wise.

Regards

Brian
