The Select comes with an OS 40 installed. Use a 10x6.

On what else to buy:

AMA Membership
Local club membership
Futaba Buddy cord (goes with the radio that came with your airplane)

Later you can get:

Field box
Electric starter
Electric starter battery
Glow Driver
Hobby wrench which has sizes for prop nut and glow plug
Extra Glow plugs (OS A3 or #8's work well)
Fuel pump
Peak charger for RX, TX batteries.


...I could create a very long list -- but these are the essentials. In the meantime, you could borrow your instructors starter gear.
