Here's a boomerang XL powered by #001 K-170, had a ton of fun over at Camp Pendleton this last Saturday, comes in slow at idle, pull up 90 degrees then apply full throttle and watch it go vertical, unlimited

So the boomer is just about stalled,with the nose pointing vertical, before applying full throttle ? with the best will in the world, spool up time is 4 seconds, thats one impressive tail slide.
