Successful Maiden OK-Model L39 with Change Sun retract

OK Model fiberglass L39 and SAPAC foamy L39

Fiberglass OKmodel L39 and Jpower A4

OK Model stock setting is buggy launch, but I install X-flight ChangeSun servoless electronic retract and shock absorbing strut. My setting flying weight is 1540 g with 3300mAh lipo. Power ~ 900W@ 48A.

The servoless retract works perfectly and really done its job! No more hopping and bending gear wire!
