The main difference is extraordinary power "authority"...any attitude, condition, throttle up and fly out...slightly "heavier" on the sticks, but I have a nose heavy CG by my choosing. It is still agile, VERY snappy, and will TR far better than I.
Mainly, I can fly ALL day for about 50 cents, as it doesn't need full throttle.
The ZDZ is very smooth...you may look at my web site for more info http://www.rcaerobats.net/H9Cap232/CapZDZMod.htm
