Fuel tank shelf

lots of sharp angles there - be sure to round all corners and sand all edges. the fuel tank is the second biggest area-load next to the pilot. If you weight 150 pounds, and your (assuming) 3 gallon tank weighs 20 pounds full, then you should have 1/7th the structure to support it. considering the series I used a sling seat, your "fuel tank saddle" looks beefy enough - but just smooth it out to avoid cracking.

and those clear fuel lines - think about replacing them with the urethane lines. the clear ones become hard as rock after about a month of gas in them, and then don't seal well around the fittings.

broke another rope - may go to steel - but the good news is the throttles are working and the fuel tank is back on board - i still need to run the engines a little more to feel confident that they will run as required-

Some of my friends come by to see if it's ready to fly yet, some are more help than others.

I'll keep an eye on those fuel lines, I was told at the time I bought tyvek were fuel lines that it was the best available. They are already turning yellow and getting hard though so thanks for the heads-up Tyler.

It's ready to fly -- I'll take it out to the Winslow Lindberg Airport and set it up this week. I just tried to taxi and one of the tailwheel's will need some more work. But I should be able to take care of that while I'm in the final set up, I hate to take it apart and put it in the trailer but it's only a two-mile drive to the airport.

the last check you should do is the hang check. and it looks like you should be able to do it in your shop.

the CofG should be 12" - 15" behind the leading edge of the wing. what both daffy and I did was hand our lazairs by the boom tube (centre cover removed), fill the tank with half fuel (as half the time you'll have more, half less in theory) and actually sit in the machine.

with the strap at the 12" mark, the main wheels should come off first and the tail should lift last - and at the 15" mark the plane should tip forward.

and please, be patient - wait for a morning/evening with absolutely NO WIND. for a first flight in a lazair, that single point is critical to a good experience for a first flight. no rudder pedals will be something to get used to perhaps?

have fun
