Hello Huang, I also got the Christen Eagle from Lion. It was in gaz power and I plan to make it running in electrical power with a 5S 4500mAh.
The final expected weight with my configuration is around 4kg. Quite heavy for such small plane.
Could you please share also with me the Lion Christen Eagle manual such I can see the specified dimensions?
In fact I do not have the length, the wing size nor even more interesting the wing area from the documentation. Without this information it is quite difficult to evaluate the wing load per dm2.
I perhaps don't need really the whole manual. What you already provided over this thread is good enough except for the wing area. Length and span I already measured them over mine but would make sence to get the "official" numbers.
I would just like to be able to complete the following table:
~50" Christen Eagle
------------------ Lion Model 60-90 ----------------- Pilot/Ok Model 40-60
Span: --49.2 inches (125 cm measured) ------ 49.5 inches (126 cm)
Lengh: 42.5 inches (108 cm measured) ------ 42 inches (106 cm)
Area: --- ? --------------------------------------------- 744 sq.in. (48 dm2)
Expected weight: 8.6 lbs (3.9kg) ----------------- 6.6 lbs (3.0 kg)
Canopy color: blue ---------------------------------- neutral
Tail registration number: N2EC ------------------ N2FC
Best regards
Florian
