RE: Which GP Flat out and recomended set up???
To elkiwi,
I bought and built the turmoil and cap 580 Paul is right they are a pain to build specially if you have not worked with foam and CA before. I replaced the standard motors with brushless motors as recomended and again as Paul advises used large sloprop 10 x 4 plus. Fun to fly ? sure, in your back yard ? absolutely VERY VERY delicate try to fly off grass.
My two bits worth, Good luck.
