Post subject:  EPP HandLaunch converted


This is my 5th plane, this time i decided to convert a hand launched glider to a RC with with a 30MM EDF fan in Wingeron Configuration,

Maiden flight was a bit shaky as the support spar wasn't fixed in properly and wasn't holding the wings properly in place.

Specs as below,
32" wingspan,
300Mah 3s
5 blade 30mm EDF with 14000kv
2 x 9g servos for the Wingeron config
10inch 5mm CF support spar,
*and a VERY Sharp box cutter... it is absolute hell to cut the foam using a dull blade.
Flying weight appx 290-310gms

I plan on adding a cheap Betaflight F3 board for auto stabilization as i am not very confident in my flying skills. for the same reason i also chose an EDF to avoid any kind of personal or property damage.

all thoughts and comments are welcome~

Are you sure it is setup as a flying wing?
There should have a tail elevator, isn't it?
I guess if there is a long tail, the elevon setup for delta wing is not effective at all, it would be impossible to fly!
