My son and I finished the decal set this morning, fine tuned the placement of the ESC, RX, wiring, RX antenna.
Take a gander at my motor mount. It is not as smooth now as with the older plexi-glass mount. There is a noticeable amount of audible vibration. Running the motor in your hand there is no noise. Running it rigid with metal to metal mated together with metal bolts there is definitely some level of noise. The shaft appears to be running straight and spins manually smoothly, I may add a plastic washer between the metal E-Flite motor mount and the aluminum plate.
This aluminum is a bit thick, ~.065". With this general set-up except plexi-glass plates I had to add 1.25 ounces of nose counter weight to achieve a neutral COG. With this set-up at 2" back from leading edge I have a neutral COG. I will double-check my numbers but I thought I remembered having my COG neutral set at 2" before.
What about the ESC/RX mounting. Does anyone feel I will get any interference issues there. The RX is mounted across from the ESC, a little hard to pick out in the photo. I ran the receiver line immediately out of the fuselage from the RX, under the window decal down the fuse passed the servos back into the fuselage, taped across the fuselage's interior ceiling and then out the top to the rigid rudder vertical wing and through the wire mounting holes there. Now if that isn't a run-on sentence I am unsure what is...
I reused the tail section from the old SC.
Any comments appreciated. P.S. disregard the mass of moving totes and unfinished drywall, new house...
