I have one going together. HS-225's, using the Turnigy 50-55,Plush 80. I think I'll use 6s 3300's. Very nice airplane. Delivery was about a week.

Flew today, tried 6S 4300, 6S 3200, and 6S 2170. Of course lighter is better, got about four minutes from the 2170's.
Had to modify the battery tray, the two 3S 3200 fit right under and over the wing tube to get the CG on the wing tube. I should try a 5S 3200 pack. Flies really nice, no coupling, nice slow landings. Still playing with elevator throws,, more is better!

The Turnigy died today after 4 flights,made a big noise and feels 'crunchy'. I will have to send it back to China for warranty. It cost $45,, bet it is $20 to return! JUst replaced it with E-Flight Power 60. Same battery and prop.
The airframe is actually OK! CG feels about right just aft of the wing tube, walls, harriers and hovers nicely. Roll rate is FAST !!
