Ok , I looked at the t-rex and Ark . It looks like more hobby shops carry the t-rex and have parts . Looking at the t-rex , which one is a good beginner ? There are like 4 different kits , are they all good for getting started . If so I`d like to get 450XL . What is the difference between CDE and HDE ? If these both are good starters which is better ? I`d like to get one that I can do tricks and stuff when I get the hang of this . Another question , Which gyro ? I see that JR and a lot others make them . I plan on buying the spektrum radio for what ever I get . I use the Spektrum radio systems in all my cars and swear by them . I hope this doesn`t seem like stupid questions and sure it has been asked before. This is all new and is another language to me.
