I'm definately in love with my 450XS...decided to go with the Spektrum DX7 with Futaba 3107's and a 401 for the gyro. Also used the recommended brushless and LiPo's. Spent some time checking link lengths and blade balance. The links I measured with a digital caliper and got them almost perfect...the blades were pretty close...not enought vibe to notice. The blades track true and used a tach to set the head speed. My ESC is a Castle Creations 35 and set the gov. with the phoenix link. I'm very pleased with the kit. The only thing I'm not thrilled with is the tail pitch slider. The bushing seems to bind alittle at first....cycling it a bunch of times and it seemed to do the trick. If it gives me problems...I can always swap to the T-Rex tail. Looks sharp...I suck at air brushing...so I guess it'll be white for awhile until I find someone with some skills I to have the Axe CP...def need a head hold...constantly correcting/trimming the tail gets old. Hell...I'm still runnin' NIMH's...flight time is short but it does the trick in the living room. Well, just my two cents....thanks, Chris
