maybe another way to get the cog closer to the prop line is to lower the motor mounting position by makeing the end of the arm hollow to fit the motor and make a something underneath the arm to hold the motor. This way you could adjust the cog closer to your propline depending on the components you choose.

does it matter if most of the mass is closest to cog or can the mass be distrubuted anywhere as long as it has the same cog position.

Im sorry i didnt say what i wanted to say very clearly. What i meant was as long as the cog is on the prop line does it matter how the weight is distributed.

wklee.fpv   Oct 13, 2017 

yes. you are right. as long as the CG is on the prop line it doesnt matter how the weight is distributed. thats why I am playing around with the motor shim and see how the COG affected the handling.

Wouldnt a true x frame be best if u want most of the wait towards the center

i think for the best freestyle frames the cog should be exactly on the prop line

wklee.fpv   Oct 11, 2017 

yes. you are right. thats why it is a low profile quads. the standoff is only 12mm tall and better use a AIO FC.
