Well you guys were right - I was out flying one last time yesterday, and my trusty OS didn't want to hand start in the sub 40 degree weather. I was able to get a few starts by running up an electric starter with a 14v battery, then bumping the spinner.
So my question is what to do to get an appropriate starter. I know there are options of using different kinds of batteries and increasing the voltage. However, Tower sells a starter specifically for larger engines, and with that they recommend the 1.2 amp, 12v 'power core mkII' battery that I have on my 'little' starter.
Should I get the bigger starter, find better batteries, or both? I currently have a 1.20 two stroke and am getting another one, and hopefully selling my .46 two stroke so I need something appropriate. Again, I've got the '90' size starter, the 1.2amp bolt-on power core, and charger.
That's exactly what I am using the Hobbico "Heavy Duty" starter with two 7.4v Racing Packs in series to increase the voltage.
This works GREAT and I can often go for weeks w/o recharging the battery.
I have NO problems turning over 1.80 4C engines and even most 50CC Gassers with this combination.
I equipped a second starter similiarly with a smaller cone for my smaller planes.
