Motor mount screws?

[Bobkeenan]

My kit for an iflight xbird 250 only has 6 screws for mounting the motors. I contacted vendor and they said I am missing 2 for 2 per motor. But there are 4 holes per motor?

They should have gave you 4 screws (bolts) per motor for mounting. And if yours included a prop adapter 2 more.

Hi mate they do this as not all bolt holes on all motors will line up on all arms so they give you 2 bolts ( its cheaper for them ) but if you look at spec of arms it may say 16mm and 19mm bolt holes so you can fit a motor thats all 16mm holes or 19mm if you look at them they are off set so you have 2 holes 16mm 2 holes 19mm apart if you can get all 4 to line up then use 4 bolts , its a cheap company that only gives you 2 bolts per motor

I only use 2 bolts per motor because I use a cheap Chinese frame which only line up to 2 holes. Be sure to use locktite.
