I've got both ...the 46 & 60..prefer the 46 over the 60...put a 91 saito on the 3rd 46..much better than the 70 they recomend...as far as 3D planes go...just so so...wing rock in harriers...have to keep on top of it....and they are not meant to fly fast...a real good 3D plane you can fly fast...go for a MoJo 40 or 60..excellent learning 3D plane..link for the mojo site..http://swanyshouse.com/index.aspx and if you want to see a MoJo being put through it's paces go to this link...http://www.youtube.com/watch?v=6pKU1LFvlMM..have a MoJo 40 with a YS 63 & a 13x6 wood prop... great combo...just my 2 cents for what it's worth...
