I run both nitro(1/8 Buggy) and electric(1/10 TC Carpet)
I don't know for a fact but I believe electric is cheeper by a bit.
But it still takes $800.00 to 1200.00 to put together a car.
Lipos last for a long while as long as you take care of them.
Don't cheap out and get a $50.00 charger for your $100.00 lipo packs
I would get a good Charger with a good Balancer and your lipos will love you for it.
an unbalanced lipo has the potental to drop a single cell below the other cells.
and you will not notice the damage untill you charge you pack again.
A balanced pack will drop in voltage equally.
I have the Hyperion 1210i with the 6s balancer I like it alot.
If the price of the power supply is a problem you can always covert a used computer ATX power supply. do a search on for atx power supply you should find it.
Or hyperion make a good ac/dc charger for like 120.00 but it only charges and discharges at 5A the dc 1210i is 10A
your choice the fun part about the electric stuff is instant power!! there is no Torque lag in an electric motor.
keep on rollin
