JAS-39 Gripon EDF (RETIRED)

This is my JAS-39 Gripon. It’s my first EDF (Electric Ducted Fan).

I’ve had a series of problems with this bird, mainly having to do with its CG. Out of the box, the plane is way nose heavy.

There is no room in the battery compartment to place a larger battery, which wouldn’t help anyway as the battery position is forward of the plane’s CG.

Nor is there any room to push the battery back farther to compensate.

I currently have a full ounce of lead taped to the exhaust pipe to achieve a decent balance but, of course, this saps my performance. It’s a shame, this would be a great plane otherwise.

No room to shove the battery back.
