I mights well chime in here since Ive had both, just 1- .46, 4 -.60 & still flying the .60 even though I have 2 50cc planes & must admit that bigger is better, a lot easier to 3-d (if you have a good one that is). Thats why I sold the .46, it only did 3-d well on calm days, the .60 was a little better in wind, but not much. I was out this past weekend with the .60, it was only 36 degrees but light winds, just perfect for tail-touchin & huckin, I must have touched 6 times at least & hovered it within an arms length, I dont have to have a giant scale plane to feel the adreniline though, I still can enjoy the Do too. The 50cc planes I have are far superior to any glow plane I've had, the Double Vision & TOC Yak are just incredible, I will keep my Do until death do us part, it has been my mainstay for over 5 years, if you can huck a Do, you can huck a bigger & better plane with ease.
