I was able to assemble my Edge and do weight and balance estimates. I did this without a muffler. I have the Standard DA50 muffler but am waiting to receive the JTec "muffler" that I ordered last week hoping to minimize the cowl opening required. The plane balanced at 5.5 inches from the LE with both batteries in the motor box. It would be very difficult to make that balance point with the servos in the tail. I am using a single elevator servo (5955) and a pushrod/bellcrank system of my own design. The elevator and rudder servos are midship; the throttle servo is just behind the firewall. I used the standard DA50 standoffs and didn't do anything to lengthen the nose moment.
The weight with no muffler, no wheelpants, and no spinner is 14.9 lbs. The pants are 3oz the muffler will be about 5oz and a CF spinner is ?oz; so I should be right around 15.5lbs as I add that stuff. I'm not sure I will go with the pants or the spinner; but just in case, does anyone have a recommendation for a good CF spinner?
