No on the brushless, but plan on upgrading very soon. My current motor gets really really hot, and just eats my batteries alive. its definitely not going to last much longer.

I am still stock on the tail rotor, but I have a question for everyone else with g90 (or similar) gyros. Without rudder input, this heli will not hold its tail in 1 position if going through the throttle quick, right? especially on cutting back the power, it seems the helo always swings right as if the tail rotor can't slow down quick enough. This is for stock tail motor. I am guessing with DD, this problem is reduced?
