Hmmm, lots of people buy motors with very flexible cages.
In my opinion why?
If you never intend to do a power forward launch (not for learners for sure) then maybe alright.
Why in this day, can props still hit the cage with relatively small amounts of force?
If you fall over on tick over, some machines will allow the prop to touch the cage…bang, there goes a prop. There are plenty of machines out there, that do not have this problem.
Worries me.
I have a friend who is very tall, and he managed to do a power forward launch, the cage flexed and he hit the prop with the back of his knuckles.
Ouch. He was very lucky it was only a flesh wound and it healed OK. Sure made him think about that. He then fitted a cross bar, which stopped the flex completely.
