470更好,原因可以看一下 There is a few differences worth going 470 (besides the obvious in size). Belt driven tail EFL head Better stance (5* tilted skids) The stance is easy to get on a 450L just buy getting a pair of 470L skids, they are compatible with no modifications required. Belt driven tail is way better on at least smaller helis! The umbrella gears in TT strips very easy, its the main reason why you should do the 470 skids on a 450 to get the ass out of the grass... DFC is a bit harder on the servos in a crash, it are supposedly not as good in lower head speed (I dont know, I have none of that issue) with oscillations. For me its working with the small (beeeep) threading the links can make your fingers bleed... Anyway... in my world 470 would be a no-brainer, I dont think they will discontinue 450L any time soon... |
