FTFC'18 WWII Tachikawa Ki-94-I designed by Airc Pirates (Twin-boom, push-pull config)

... If I still had 2 power pack A's I would totally build this.
You can also use F-Pack motors. One of them should give you enough thrust! And if you install the motor in the back you can add a camera in the front! That would be an ideal FPV setup. We're gonna test it.

And with two F-Pack motors and a 4s battery, the Sumo Fighter turns into a Demon of speed. ;)

Tony, with one F pack in the back what kind of battery would you need up front for the CG? Something bigger than an 800 3s?
Jason, with two A-Pack motors and two 12A ESCs I need a Zippy 1000mAh 3s 35C (Weight 95 g) for the perfect CG. With one F-Pack motor in the back, a 1300mAh or 1500mAh battery with 3s should be sufficient. You can still position the ESC and the receiver to reach the perfect CG.
