It ain't heavy, it's my Skyfun!

My other Skyfun (Twin motor/prop with landing gear) was heavier and flew great.
All of these planes I've been working on (Twin Raptor, Twin Skyfun, Tri Skyfun) have been proof of concept projects that do get heavy as I try out different things. I guess once I figure these ideas out I'll start from scratch with a new kit and transfer everything over clean and apply all the lessons learned, including weight saving strategies.

For the ducted fan Skyfun a friend and fellow flyer had this Eflight 80mm EDF laying around and loaned it to me to see what could be done with the Skyfun so I'm giving it a try.

Regarding CG, with the 2800 mah batt near the nose it balances out per normal using the finger holes.
