Worked on my Composite ARF Extra tonight. I wanted to check it out and see if I could find some reason why it died at half throttle causing me to land in a farmers field, but then restart on the second flip and run perfectly when we got it back to the pits. I decided that while I was at it, I would change out the DuBro tank for a water bottle.
Since all the batteries are mounted in the engine dome for balance, working on this thing is a challenge to say the least. It's really crowded in there.
I did find two problems. One was an O-ring trying to escape the fuel filter, and the other was the throttle servo was trying to fall off.
I ordered a Fortitude 20 ounce tank. I know there have been leak issues in the past, but the version 2 is supposed to be good. I guess I'll find out.
