RF transmitter resistor wattage help needed

Hello,

I am planning on building this portable FM transmitter. However, nowhere on the site does it say how many watt resistors are used. At first I figured since the high power RF output is 1W I would need 1W resistors, but now I don't think so. Can somebody take a look at this and tell me what resistor wattages need to be used?

Thanks

Generally if the wattage isn't listed it's 1/4W, and if you look at the picture all resistors are small ones.

Ok thanks for your help.
