I worked hard over the last few days and all through the night on Monday to finish my new Extreme Flight 95" Extra 330SC-E for a maiden flight Tuesday morning (yesterday). I tried to minimize modifications to make the build go faster, but couldn't resist a few changes. One of the time-consuming mods I made was to automate arming of the ESC. That added a total of 1.5 ounces to the AUW, which came out a bit heavier than expected at 20.6 pounds. That's with 5 pounds of batteries! (8000 mAh Glacier 30C LiPos) At least it's lighter than my 87" Extra, which has 6000s.

ESC arming is controlled by a micro DPDT switch mounted to the fuse right below the fail safe pin switch. The pin has a "Remove Before Flight" flag attached to it, which covers the arming switch when the receiver power is Off. That provides a reminder not to arm the plane until I pull the pin and power up the receiver. The ESC arming switch has no power, though, until the pin is removed, so there is some redundancy there.

Fail safe was checked and tested this time!

A couple other minor mods was adding a nylon spacer to extend the wheel axles. That provided a resting point for a support block glued to the inside of the outer wall of the wheel pants.

I didn't add a custom battery tray to this plane to save weight, and I miss that already after two flights! To avoid the hassle of removing batteries stuck tightly to the deck with velcro, I used rubber stops supplied by Aloft...Continue Reading

The weather is perfect now for flying, but I'm grounded until I finish my new plane, a 95" EF Extra 330SC. I hope to fly it in the first IMAC contest of the season (here in the Midwest) May 19. With all the work that goes into building and preparing it for the maiden, then trimming and tuning flights, it sometimes feels like I'll never cross the finish line, like running a marathon.

Cincinnati just had the twentieth running of the Flying Pig Marathon today. If pigs can fly, anything is possible, right? I've run many 5K, 10K and 15K races, and a couple mini-triathalons, but never a marathon. My son ran it for the first time today and finished in about 4.5 hours. Congrats, Aaron!

Now, back to my build....
