MK produces several kits which are about the right size for that engine:
Alliance CP, Silent .90, Wild 7 .90, Aurora .90, also a new kit of the Synergy .90
These are available from Singapore hobbies (
www.singahobby.com and
www.hobbynet.jp)
The 3D Dancer is too big for that engine.
Dick Hanson kits the Runaround/Runaway with a small (700"sq) wing which was designed for the original OS .90 surpass. If your engine has that much power then you might consider one of those.
Good Luck.
