Judging by my avatar you guys could tell this is really one of my favorite 3D planes ever!!! I do own the actually one in my hanger on here I've done so many edits of this plane being from 46AX, 50SX-H,55AX 3 Electric versions from 4s to 6s set up's till recently putting 2x 3s lipos on it etc. So I figure why not go really the last extra mile by really over power it with 70SZ-H helicopter engine swinging a 14x4 prop! Enjoy it!!!
