RE: Tf Dc3
Mike,
Oh sound wise you are going to love it, i flew my B25 with 2x MAG 25 2 strokes and its is awsome sounding plane, once engines are properly sync they just hums beautifully, i love that sound myself too. You are rigth of financially OS 46's are very resonable and readily availabe anywhere and are very reliable engines, one of reasons of chosing 46Fx's was the reliability of them. You will be very happy with them.
Kind Regards,
Sammy
