Just a little clarification in relation to the rolling harriers. If, while rolling, the aircraft is descending, you simply add some throttle to bring the aircraft up. Really simple to do. It is also a timing and coordination trick which is rather easy.
In a rolling circle (no matter how many rolls, as long as they are COUNTED and DETERMINED before the roller even starts) if you want to gain some altitude you may need to input elevator, up or down and/or rudder left or right. You have four distinc possibilities and combination of each also. Soooo gaining altitude is no simple thing, it is a combination of all disponible inputs in a controlled manner, not timed manner.
More to the point - if you start gaining or losing altitude - you start LOSING points !! The difficulty lies in NOT gaining or losing altitude.
NOT gaining or losing altitude in a roller is only ONE criteria for KEEPing your score at a perfect 10.
There are many other ways of losing points while performing a roller ( or any of the other figures in the Arestic catalogue).
Trying to KEEP that perfect 10 for EACH maneuver in your sequence is the difficulty, the challenge.
Understanding the basics, the guidlines, on HOW to KEEP that "perfect 10" is a challenge in itself.
Perhaps a better understanding of how the flying is JUDGED in IMAC might give you a better understanding of the answer you are looking for.
Go to the IMAC website at
http://www.mini-iac.com
Go to the Rules section and download the Flying and Judging Guide.
Read that and begin to learn the criteria of how a flight is judged and scored in IMAC.
It might help you get a better feel for what IMAC, and precision aerobatics is all about,
