The Katana has the 23.6cc Echo that I did all the hop up mods to, including the stroker crank mod. Turns an APC 16 x 8 at over 9000 rpms. I don't think it will hover with that much pitch in the prop in this combo, but when I pull it to vertical it gets really small, very quickly...

The first post at the beginning of the previous page has info on the Super Tiger .90. It had been modified by Keith at BME to run on a regular gas/oil mix with roller bearings. I chose to run it on Gas/Glow. It runs and handles super, but see the post above for more info.

48cc twin? See here: http://www.rcuniverse.com/forum/m_5422664/tm.htm
