OK .. I have another question for the resident guru's. A few years ago I designed and built a control line stunt canard. This aircraft featured not only the working canard but also a working elavon in the tail. The plane has a foward swept wing and was powered by a OS-46LA. The wing area is close to 550 sqin and a weight close to 50oz. (I will attach a few pics at the bottom of this post). My questions are this .... 1 .. what size and how many EDF powerplants should be used? 2. Is there any chart that can tell me the proper conversion from regular glow to EDF engines ... or maybe it is a chart based on wing area and weight vs EDF size?
