Weight savings of CF frames for Raptor 90?

[creightoncarr]

I've got a R90 converted from a R60 and am still using the R60 aluminum frames. I'm curious if there is a significant weight reduction in using the CF frames over the aluminum. My all up weight with fuel is about 11.5lbs. I'd like to try and find a way to shave off about a pound.

I think taking of the bottom plate and getting a Vmax upgrade would do the job, but why try to save weight?

You can also take a very light rx battery.

I'd like to save weight b/c I love the way it flies with 1/2 a tank of fuel or less, but with a full tank down to about half it's a little sluggish fr me by comparison. By shaving off some weight I'm hoping I can get it to fly with a full tank like it does now with half.
