RE: Wing loading
Hey, don't add weight..... move something forward! The battery is probably the easiest.
Using carbon fiber tube for your pushrods in the tail might shed weight.
What size Rx battery are you using? If it's 2000mAh or something huge, you can go with something smaller.
It's kinda fun to go through a plane and squeeze weight out of it. I lost 3oz on my 6lbs plane without spending any money. Not that it made a huge difference in how it flew, but it's the principle I suppose.
You should really post some pics and a complete equipment list. Maybe we can help.
