Well, from what's been said, it sounds as though the .55 AX is way more than enough power. Maybe the Thunder Tiger pro .46 is adaquate. I had one of these a couple of years ago (sold it), and loved it. It is less expensive, as well. On the other hand, when practicing on the sim, it seems that the more power the better when trying to get out of a tight spot close to the ground, i.e. when in knife edge 10 feet or less from the ground, top rudder and full power can save you! I'm not sure if the Thnder Tiger could do that. I am not buying anything for a month or so, I will mull that over. One more thing, I'm an 'expo' junkie on the transmitter, and often use up to 70% when flying the fast ones. What do you guys use when flying 3-D......expo, dual rates, or none? Thanks.
