ahhh loops are easy with the avistar... if you can touch and go loops are easy... just get some altitude and pull full elevator when you get to the top of the loop reduce throttle and keep the elecator at full will loop easily... try to loop into the wind as this will make it easier, you dont have to but its easier i think.... i have the avistar and if you can make inverted circles you are ready for loops avistar will do inside and outside loops try going inverted with good altitude and give it FULL down elevator it will do a nice outside loop or you could even end the loop at the top and use it as a turn around manuver.... what size engine do you have on your and what prop... i have the 40LA and 10x6 master airscrew
