Well brushless motors don't die that fast...
Have you subtrimmed the 130x pitch for zero pitch?? If not you have way too much pitch one way and no matter what motor you put in it, you throw too much pitch on it, it's gonna bog.. There's only so much to these motors lol
Next thing : collective management.. If you are using a lot of left stick in multiple flips , then that's bad collective management .. You can bog a 700 motor with that too.. Which then will cause a lot if blade flapping on those soft blades and loss of tail hold and tail wag..
Cyclic is your friend.. Use that more than the collective stick .. Try to do a flip by moving the throttle stick as less as you can
Another thing..
What blades? Stock blades are soft and flap too much under load and this causing vibrations and Abd causing tail wag.
Now if you definitely want to get a bigger motor (better) try spin 8000 or hp08 ..
I use hp08 as you know and I love it
Just so you know I can bog these motors too if I don't manage my collective
Mcpx and 130 and all are very good birds to learn collective management my brushed mcpx trained me well.. Hear for a bog and try to minimize it by goin down on collective pitch and compensating ny cyclic
Please don't think that I am trying to say you don't know this and you don't do it
Just making sure I put this info out. : just in case
Fly safe!!
have fun!
