it all depends on:
Money available?
How serious you wan to get (refer to money)
How many people involved? 1 or more (refer to money)
Indestructibilty
ease of flying
combat fun with the ECM

Purists may sneer at the fighterbirds but as a father of 2 boys, a fighterbird each was the best money i spent for the fun that these flyers have generated.

Sure, it is not a scale model with all the bells and whistles, but spare a thought for us who just want to have some fun but cannot invest large sums of time or money into the sport.
