Battery

I used to play RC in the 80s and collect vintage RC now.
In the old days, Sanyo 1700SCE is the king.
I want to run my old boomerang.
1. Is Sanyo or panasonic still the king? Any reliable battery brand recommend?
2. How many "mAH" for the battery nowadays?
3. How long can it run on a stock 540 motor?

Many thanks.

1. NO, IB & GP.......ETC.
2. 4600
3. 大約 30min.

the size of modern batteries lengthened a lot, they may not fit into the old battery slot very well

thx C-hings.

Use Li Po battery. Both the charger and battery are cheap now

not all old car chassis can hold li-po
at least, my TA-01 cannot straight fit
need use a sender modify lot!
