Sig LT-25 conversion
Steve, Yes my friends LT - 25 uses 10 cells (2200 mah Radio Shack Nicads) and an 11 x 7 prop.
If you use a Magnetic Mayhem you must use the M M Reverse when connecting it to a gear box.
If you do not have a motor, take a look at the other Kyosho motorss in the same series - the Kyosho Atomic Force and the Endoplasma. They are lower wind motors and require a higher gearing than the Magnetic Mayhem --- Great Planes makes an economical box that will fit.
