CG & Max Rate of Climb

[Macgyver]

Hey guys,

I was just curious as to whether or not the position of the CG will have any effect on Vy (i.e. the speed in terms of IAS), and, will it have any effect on your ability to achieve a maximum climb rate? (i.e. if the CG is more aft, will it be able to obtain a higher rate of climb at Vy compared to a forward CG?)

I have argued that the position of the CG should not have any effect on your ability to achieve a max climb rate; however, some people have told me an aft CG is favourable. I guess in case of stalls, an aft CG reduces the stall speed... are there any similar benefits for climb rates?

Thanks in advance!
