The 2x Butterfly

This is my scratch built 2x Butterfly. Right now the airframe weigh 2.5 grams. I am planning to use a 6mm motor and 40mAh Lipo with 0.5g home made actuator.

The real Plantraco Micro Butterfly is also there as a reference.

Any suggestions will be most welcomed!

Cheers

Wasn't the micro butterfly already half size of the original balsa butterfly? So yours is a foam version of the old one? Or is the span different?

Here is the original balsa butterfly http://www.microflight.com/Butterfly-Livingroom-Flyer
Uses a 4mm gear drive and 30mah cell.
Looking at the old one, its span is 6.5 inches so yours is still larger and could handle the 6mm motor and 40mah cell.
