Soon to testfly Vmar Cap 231ex
I can hover it but it takes alot of throttle even with the .61 (12x5apc) because of it's weight. I weighed it again on a digital scale and it says 7 lbs.. It's a tank for a 40size cap. I have done blenders with it, torque rolled, lomchevak, etc.. Mine tumbled great.
It has alot of coupling in knife edge flight..
It snaprolls like a blur.
The 40size aerobats are not the best choice for 3D.. Start with 1/4 scale planes and up for easier 3D flying.
