I have a Sig Wonder that I build, I was going to use an OS 15CV-A on it. But decided to go all electric, now I have a NIB OS 15CV-A that I need to sell. Anyways, I mounted up an E-flite Power 25 with a 40 amp Pro SB Brushless ESC. I have 2 3200 mah 3-cell batteries that I can use for it. I have not flown it yet, but I have everything balanced out and it should be ready to go. I mounted a 12x6 prop on it, and this thing pulls. Once I go out and get more time on a trainer again I will fly the Wonder. I haven't flown a plane in almost 8 years.
