RE: JR Propo explorer v50
I had one of these.
I weighed it and fondled it lovingly before I sold it unassembled. So I can not give you any flight reports yet. A friend bought it & I'll get to see it fly later.
The one I had felt nice & lite, was assembled well and I had intentions of using a Irvine 53 on it. My opinion ( for what it's worth) is If I had a OX46AX I';d certeinly try it. You may not have unlimited vertical or be able to "blast" out of a hover, but it should definetly fly the plane.
