I'll be using the new JetCat P130RX that weighs just a little more than the P100. This should save some weight in the back end and I will try to move everything forwards as possible as well.
I just installed the nose gear door servo as I am going all electric. It conveniently fit in the existing hole in the first former. I have room for both receiver batteries along the sides of where the retracted nose gear sits. In front of all of this the ECU battery can sit at the tip of the nose cone. I will be fitting a real pitot tube for true airspeed up there as well.
