As far as glow plugs, they are #8's in the engines now. I used the break in procedure called for in the instructions and it seemed to work well. And, I believe I used 6oz. tanks. Not much room for much larger in the nacelles, but they should be adequate since I don't plan on very long flights with it at a time. Still had lots of fuel left after considerable run up time here in the back yard. I had planned on flying it this past Saturday but weather still not good, and I'm tied up for the next several Saturdays, so the first flight may be on hold for a bit.
