| used to be 1.5v, now its generally 1.2v from a Nicd cell.
Of course, that NiCd cell could be anywhere from 1.4 volts to 1.0
volts or so. (And that 1.5 volt battery starts at 1.5 volts and goes
downhill from there.)
| We used to use 2.2v lead acid in my day. They ALWAYS started...till
| the plugs burned out anyway.
I'm not so sure that having glow plug burning extra hot would make the
engine that much easier to start. The hard part is getting the right
amount of fuel and air into the carb -- once that's done, as long as
the glow plug is working properly, the engine will start.
(Of course, getting that part done isn't that easy.)
In any event, I agree with the others -- an electric starter is well
worth it. A properly tuned and primed engine will start just fine
with a chicken stick, but getting it to that point is hard, and a
starter will make things a lot easier.
If money is an issue, scan your local craiglist, local *.forsale
group, even the local club bulliten board -- people sell used starters
quite often, sometimes even giving them away. Often you can find a
whole box of almost new plane accessories and a smashed up trainer for
next to nothing :)
If you can't get a starter, at least get a stick or something -- don't
use your hand unless you use a thick glove, and even that's a bit
risky. Even a little 0.061 can cut you up nicely.
I'd suggest not using a screwdriver -- if the engine backfires or you
accidently put it back into the prop, it can become a projectile and
could take out an eye. A dowel or a broom handle cut off will work
fine and isn't quite so sharp.
As for the glow ignitor, get something that holds on good to the glow
plug -- anything less will just aggrivate you. The ones with the
meters are well worth it too -- they'll tell you if the battery is
dead or the glow plug has been burned out. (Note that there's two
parts to a glow plug -- the coils, and the catalyst coating. If the
coating fouls, then the engine will start as long as the glow plug has
power, but will die when it's removed. Just because a glow plug
lights up, that doesn't mean it's good!)
