P-51 B,

I think you make a good point about the cost of the batteries as that IS the primary reason why I have not convert any of my 60-90 sized glow planes. I have been flying the Multiplex Magister (66 inch wing span) and the cost of a brushless motor, ESC and regular 10 NIMH cell totaled about 225.00. For that set up, it is way better than installing a 40 sized glow on that plane. One nice thing about electric is that the plane's airframe does not age as fast as with glow. As far as Lipos are concerned, I think that at this time, they are over priced and unaffordable for bigger planes and not quite reliable. A hard crash and the batt is pretty much damaged beyong repair. Not to mention exploding if overcharged. When I think of Lipo undergoes charging, the Me-163 comes to mind. At the fast pace we are going now, realiable, affordable Lipos and brushed motor is just around the corner.
