Can anyone tell me the CG from the nose of their "built per kit instructions" FatBoy WITHOUT the motor inserted.

EMRR has the CP listed...My guess is that the CG is up to the builder since that's all he can change without changing the design.

Don't you really need the stock CG with the largest recommended motor installed, rather than without a motor? That's the point you'll be trying to get back to in your modified Fat Boy... which sounds pretty darned cool, btw.Originally posted by Fuddrucker
I got that, but I am just trying to get an approximate CG point from a stock build. I realize that no two builds are going to be the same because of build factors like how much glue is used, paint, and finishing techniques. However, the differences should not be that much.
Still, don't you need the CG of the stock Fat Boy in its launch configuration, fully loaded with motor, wadding, chute, etc.? What you're trying to do is to get the CG of your modified Fat Boy, fully loaded with all 5 motors, in the same place as the stock Fat Boy loaded with, say, a C6-7.Originally posted by Fuddrucker
BUT, since I have already added weight by a heavier motor mount setup, I am just trying to get the relationship of CG/CP from the stock mount. If I took the CG of a stock kit with say a C6-7 loaded, it would not be nearly the same as mine with a C6-7 loaded since my mount is already heavier without a motor.
