check out the shops that sell radio control stuff, Chris
There's one in Ravenna on the west end of town.
On Riddle st (I'm pretty sure it's Riddle st)
Just a block or three west of Sycamore st on the south side of Riddle.
If it's not Riddle st, it's the next street south (Mill st ?)
You see an electric sub station on Riddle, the radio control shop is behind it.
That's where I buy the batteries for our Muli-sprayer.
$20 bukz
