I see alot of ppl reccomend a 50 size over a 30 for a beginners....
Since I am soon to be a beginner to R/C Helicopters I ask....
Why a .50?? From the videos I've seen online the .30's are quite capable....

Also I'm looking at the raptor .30v2 is can you upgrade it to a .50 size? I mean is the .50 just bigger blades/longer tail boom? or is it built totally different?
Thanks!
