RE: Mini 3d
This is a passage direct from the manual:
"This is a great 3D performance Airplane.
All part are weighted and matched .
Every plane net weight between 345g-360g. ( not included accessories parts )
This plane should not fly over 900g RTF. Weight to keep it in highest performance.
Our test model average weigh from 840g-880g. that was depend on what kind of Engine, receiver and
battery you install on the airplane.
And we do not recommend to use over .20 engine for this airplane."
I have the manual in PDF if anyone wants a copy. Just post or PM your email and I'll send it over.
