RIN,

first we need a little more info like the weight of the plane ? also the 4.8 volt battery you have is just to power the reciever it wont work as flight battery for the motor.

as far as cost goes it wont be anywhere near $300.00 unless your buying ALL top of the line most expensive stuff you can find

im flying my super sprotster EP with the stock brushed motor and gear box jut using different batteries and it flies nice at 3 1/4 lbs and the motor gearbox combo set-up thats fairly inexpensive and if the all up weight is 28 oz or less you could use the new 400 outrunner brushless motor that world models has for $25.00 ESC is $39.00. and the batery packs can be nimh or nicad.

here is a link to the motor and esc = http://www.airborne-models.com/html/...asp?AGroupID=6

NOW WITH THAT SAID IF IT IS YOUR FIRST PLANE , PLEASE GET A TRAINER TYPE PLANE FIRST.


hope ive helped you some.
