I was quite disappointed with the Brio 10's performance with the 480 motor... let alone how fragile the Brio itself is...
I had one of these on hand

So for yuks I installed it on the brio.
WOW what a difference using nothing more than a cheap $17.00 motor.
I used the same E-Flite ESC and transferred the prop mount after cutting down the threaded screw.
Now for 8 mins or so I get truely unlimited verticals, and the plane will hover at about 30% throttle.
