-Doesn't have an
integrated AA battery compartment
-No cheaper (hobby
shops have them for about $10)
-Not designed
specifically with fuels in mind (though, they may very well
manage it)
-Setting it up to
pull oil directly from the bottle it was sold in saves the
mess of an additional transfer.
Having to string a
cord out for power would be the only real drag, IMO.
As far as pumps go for adding 2-stroke oil
to the fuel inlet ....... couldn’t you just
use a windshield washer pump?
Shoot, you could probably get away with
using the reservoir as well.
