Lighter components for this cheap-n-easy build

[NoCG]

Hi!

I just gave the cheap-n-easy wing a try and we were able to fly it. The build came out to be a bit heavier than I wanted but that is to be expected with the battery and motor I had. I think I also have a bad servo on the elevator - it starts shuddering if the elevator is pulled all the way.

Right now the AUW is about 275 grams. It has:
-- 2204 2300 kv motor with 5x3 prop (26 grams)
-- MG90 servo (2x 14 grams each)
-- 3s 700mah lipo (68 grams)
-- turnigy plush 20 amp esc (16 grams)
The foam with dollar tree foam with paper on both sides.

I have the 3s 700mah and 2s 850 mah and would like to stick with these voltages as I would not want to go into 4s.
Is it possible to make this even lighter - I would like to use light motors and smaller props. Would the emax 1306 4000kv work with 2s and 3s?
As for servos I might give the emax 9051 a try. I just want to ask before I start spending money.

Thank you in advance.

That's already a pretty light setup you've got there. My guess it your issue with the plane is its speed, which is not necessarily the AUW's fault here. The CNE is more suited for an 8" prop for slower flying. That 5" is generating enough thrust to keep you in the air, but the airspeed is much higher so the plane has to fly faster to stay in the air. Everyone's favorite setup for the CNE is this motor: https://hobbyking.com/en_us/hextronik-24gram-brushless-outrunner-1500kv.html and an 8x4 prop with a ~800mah 3s

i agree with @Rcjetflyer2, I don’t see room for a lot of weight savings. You could save a few grams with plastic gear servos & try building a lighter airframe. Glue is heavy, only use what is absolutely necessary. Weight to power is always critical, it’s especially difficult with smaller planes.

Wing loading has 2 parts, weight & wing area. It may be easier to make a larger wing than to retool your components.

Just looking at the pictures, you could be nose heavy. I always start with CG at 25% of the wing area.
