Shakes, i entered from a blender and yes on the high rates, i have mine set at 1/2 in low and 3/4 high and after flying a ucd with 3.5in throw on elevator i was a little skeptical about it being able to do it at 3/4 in but it was awesome with a little right aileron to balance and iwith my saito 100 i believe it was around 1/3 throttle and it spun kinda quick but was what i think was a perfect flatspin, couldnt get it to rise like my ucd46 but was way past my expectations
almost forgot, Max Rudder also!

next is the knife edge spin[8D]

have fun
