Default Lighter wing loading???

I have been looking to buy a new plane, however I have no idea what I want. Cant do 50cc right now as I cant transport...and the current 1.20 size planes dont really speak to me. For now I think I might decide to strip my showtime and recover and lighten. After a very rough calculation my wing loading is about 22 oz/sq in. If I was able to bring it down to say about 19 oz/sq in....would this make a big difference in performance? Looks like I might be able to save 5 oz by swapping components(below). Again rough calc, would need to save 8 oz to hit the 19 oz/ sq in. mark. I might be off.

Anyway I am currently using:

Dubro HD control horns all around - these are all metal so im sure I could save an ounce by switching all to something lighter

Landing gear - could prob save 1 - 2 ounces by going CF

Throttle servo - switching to an HS-82 would save one ounce

APC prop - going to wood would save one ounce

Possibly i could find lighter wheels - dont know if the difference will be that much

Axles - currently using 5/32( i think) dubro. Probably bigger than I need. Dont know if its worth the hassle of going down a size.


What do you guys think? Wondering if the 3 oz/sq in wing load difference would make a noticeable difference in flight.

Any input would be great.
