OOHHHH. I assumed you where a total beginner. Sorry.
Then may I suggest building the FT Baby Blender. Since you'll be building it yourself, you can easily make changes to the design. After you build one like it's supposed to be that is.
Looks great to me, I would love to see a swappable version of a decathlon or a cub either super or piper. Looks go so far, Keep up the good work. I look forward to downloading plans and building one myself.
