I could have done that, but I actually was trying to do manoeuvres without power, and keep it up as long as possible while doing various things. If the wing was stiffer, I probably could have dived to get speed and then pull up and settle out on the top of the loop, but as soon as the plane gets speed in a dive, the wings really flex when trying to pull out.
