I just got done flying mine... What a blast... I have a new Magnum .70 4s in mine... Have probably 5 tanks through it... The plane and engine are both doing great.... Question.... I have a 13X6 APC on it now for breakin.... In the air this setup will fly the plane fine at half throttle in a mild scale like fashion... If I open the engine up I can hear it roar to life but am not seeing any change in the planes performance... Is anyone else flying this combo and if so have you found a good prop for it... I want to get a coulpe more tanks/flights on it and then I am thinking of going to a 14X4 for pull.... Vertical is not that great now... This plane weighed out at 8 pounds with the Magnum and it is spinning the 13X6 APC at 9700 while still on the rich side for breakin....

Thanks
Roger
