Using a TP 3S 730 indoors on a Yak 54 Shocky and getting tons of flying time out of it. Looking at going to a little lighter battery to check out the difference. The 2S 730 and the 3S 480 weigh the same and both cut over 1/2 oz off the weight. I'm new to this stuff and don't really understand what the difference in these would be and which I would like better. Most flying now is under 1/2 throttle and hardly ever use over 3/4. Suggestions??

AXI 2204/54

Weighing in at around 7 1/2 oz

I have a general suggestion and that is check out any motor/prop/battery combination on a whattmeter. Overdraw kills a battery. Fast. If you are going to try and cut it close, you need to know exactly what amps you are pulling. To be safe, never pull more than 80% of the rated capacity of a battery at WOT. Don't be fooled by thinking you're OK since you usually fly at half throttle. Speed controllers are like little on-off switches, calling for full power whenever on. Even though the 'average" amps are in spec for a battery, if all the litlle peaks are over drawing you'll kill the battery prematurely. Sort of like...If you tried warming your hands with a blow torch, one second on, ten seconds off would be fine. But 5 seconds on 5 seconds off and you'd have a bad burn. But a heating pad you could leave on all night with no problems. The heating pad is in spec with what your skin can take. Similar principal. Pay attention to the maximum amp draw and keep in in range of what the battery can comfortably deliver. If you don't have a WhattMeter, I suggest getting one. For about the cost of one battery, you'll save all your batteries. -Fred
