If I could only have one plane, I would choose 3d. I find it much easier to pattern fly a 3d plane than to 3d a pattern plane. it is challenging and not perfect but I will start with square loop with 1/2 rolls, figure m with 3/4 rolls - my favorite then when fuel is burned off will bring it down and touch tail in grass. the theory that heavy over built airplanes hold up better for damage is a misnomer. I drove my 4lb 3d plane into weeds at full throttle last year - as I walked over to crash site with plastic bag I feared the worst but discovered there was no damage, just prop, I squeezed the canopy it popped back in place, switched prop and flew it again right away. you can drop a potatoe chip from a tall building if it lands in weeds it probably wont break.
