I third going with more powerful motors. My first A-10 had P120s and that's as small as I would go if you want to immulate the full scale plane. Mick is spot on about needing the extra power for aerobatic maneuvers. Mine never felt "over powered". My current A-10 is getting a pair of 160s. I spoke to Mark Hinton about his A-10 and he said the 100s were underpowered for his taste.
