Can I substitute different parts in this kit?

Sorry, all kits are prepackaged and generally can't be changed. If you have a custom list you'll have to buy the parts seperately. The only change we will make to this kit is if you want a different gauge or color roll of Deluxe Servo Wire, limited to our Deluxe Futaba or JR 22, 26, and 28AWG 10ft rolls.
