LEGO bricks

I've got the LEGO bricks from The_Duplo_Store via bricklink.com.

• [Used] Dark Bluish GrayDuplo, Train Base 4 x 8 with Light Bluish Gray Train Wheels and Moveable Hook
• [Used] OrangeDuplo, Train Locomotive Cabin Roof 2 x 4 Studs, 4 Medium Windows
• [Used] OrangeDuplo, Train Locomotive Front with Silver Headlight, 10508 and V Stripes Pattern
• [Used] RedDuplo, Train Passenger Locomotive Base with Black Battery Compartment, Light Bluish Gray Wheels
• [Used] YellowDuplo, Train Cab / Tender Base with Bottom Tubes with Box and Arrows Pattern on Both Sides

The bricks required thorough cleanup, but hey, batteries included..

Radio control

I've bought a 433MHz transmitter + receiver modules (http://www.ebay.com/itm/380717845396). This is the first time I'm dealing with RF so troubles are to be expected, but I'm not rolling my own transmitter or receiver so I should be fine, right?
