Well I'm happy to take advice from anyone - and by the sounds of it I need it!

So what do people reccomend for a heavy lifting airfoil ?

The camera platform has an 80" span, will be powered by a .46 engine and hopefully should be capable of lifting a payload of about 1lb

I originally started with clark-Y and then graduated to SG6042 as I thought that was a better choice. No I have no idea
