Some hindsight now that the wing is finished ..
I built it as it was designed to be built = WRONG !
My goal was to go light , I did that .. But the weight is in the wrong place ..
It takes a 700mAh 2s to balance the wing .. ( Makes it heavy )



What is required is a complete redesign or relocation of components .
The motor needs to go where it goes ..
But everything else needs to be located near CG ..
I would suggest burying the servos in the wing ... ( @ CG location )
Have as much weight around CG as possible , so a smaller battery can be used ...

Also the 1306 4000kv is overkill .. ( who does not want overkill )
@ 50% throttle with a unknown battery ( voltage state ) I had 1 to 1 power to weight ...

Will there be a 3rd Spirit 600 ( ?????? )
I would want an even smaller motor , maybe 3000kv . Maybe a 6A ESC .
These 3.7g servos seem to be enough , 9g is overkill .
Smallest 4ch Rx ...

Put as much stuff @ CG as possible .. That way the battery has to only offset the weight of the motor ( and ass end of model ) ....
Hmmmmm , now I think about it ( Hindsight )
