Hi

i dont think i would bother with any of those, like the others sya, you could build your own for that, a little more money, you could build one 10* better. There are already some good designs on here and some already done in sketchup for the size your looking for. I will try find the ones i was looking at in sketchup, they was compleate, I would imagine all them have rigidity and accuracy problems.... You may get away with cutting a wing profile in foam with them, but i think, ( am also into RC ), you might struggle with smaller componants on them. especialy hard small parts ( alu car frame, helli bits, cam holders ). Do You FPV ?
