AN E-Version of the Kyosho Agwagon to Electric using the MAXCIM N32-13D brushless motor. I have always wanted to have an electric Piper Pawnee but unfortunately I could not find an ARF for it.. Eventually Kyosho came up with the Agwagon and I decided to make an attempt for the conversion.

The Garden Cub is designed by Neil Gillies    The article includes free Plans. The design is a 1 meter span in order to make it able to fly in a slight breeze in its role as a parkflier. Designed for a Speed 280 2:1 on 6x350AAC cells - nice flying but not much climbing power. Next I used a Speed 300 3:1 on 6x500AR or 6x600AA cells, this is my preferred setup. gcleft.jpg (31114 bytes)
