70cc twin V2
got my chuckle down, thanks Joe
A chuckle is basically a normal tumble starting from inverted and then switching the aileron direction. A normal tumble would start from inverted, the right gimbal would go to the top right corner, and the left gimbal would go to the bottom left at the same time. A second after you do those inputs, switch to full left aileron and it should flatten the plane out and cause it to end upright, facing in the opposite direction.
