42" KFm4 Depron Slope Soarer with 48" KFm marginal condition wing
Just a new addition to the nest a 42" depron slope soarer
couldnt find one in the scratch builts so I designed this one myself
KFm 4 wing made of 3 6mm depron pieces and the fuselage
built on a pair of pine longerons with 6mm depron tailplane and fin
2 channel 3 servos 315 sq inches and 17 ozs . wing loading of 8.5 oz sq ft
The wind turned up in the right direction today . 17mph .
great test flight . I was surprised how aerobatic it was with the small control surfaces 1" ailerons and elevator. loops, rolls and inverted flight without problems the KFm 4 worked well . if anyone is really interested I will describe the build fully . (Its a days Build from start to finish)
Have built a KFm 3 for more marginal conditions with 1.5 " ailerons and 48" span
fitted servos now the wing is complete and waiting to test fly when conditions improve
Here is the KFm 3 wing photo added 3/7/12
Built on Falcon Technology and the forerunner to the Funmaster see the falcon thread
Both slimline versions of the falcon but using KFm wings and doubles as a test bed for new wings using the now stock 42x7.5 wing sizes for holiday models
regards all emma

Congratulations on this successful flight!
Simple design and good proportions seems the key to success here again!
