RE: Suggestions for 3D plane
Try the Pigi 3D from [link=http://www.hobby-lobby.com/pigi.htm]Hobby Lobby[/link].
Mine flies awesome with only the Mega 16/15/7 motor...perhaps because it is 8oz lighter than stock.
Check out my thread [link=http://www.rcuniverse.com/forum/Pigi_3D_from_Hobby_Lobby/m_1153270/tm.htm]here[/link].
Good luck!
