$459.... and you can use the charger on other things.....
$459 - 70$ for the engine part = $389 = @ 22 gallons of glow fuel...
which you no longer have to buy.....
I can burn 20 gallons EASILY in one summer...
Not disagreeing with your math, but 20 gallons on a .25 engine would be a huge amount of flying!
