hello, mark suggested that i ask you as you could give a better recommendation. i'm looking at buying a hyper tt after seeing them at MP. i spoke to Kev at hobby habit he was saying the 5.5 is probably the best motor but thinks the 4 pole will do fine with out problem... but he said the motor must be hobby wing brand. if i do go the 4 pole style sct there are 3 different kv's 3400kv 4000kv and 4700kv. are they all legal and which one is best???
cheers
