I have been involved in this sport for many years.
In my country I am a judge and I see very followed competitions. Permanently I fight so that what it cares is the precision of the maneuvers and not the airplane with which is carried out them.
It is acrobatics of precision..... it should not care the rest.
This fair serious way that the best pilots are those that win the competitions and not those that have but available money to have the models but light and with better power.

Sincerely

Mario Vagliente
