Guys, Thank you, Thank you, Thank you! You're so right .... I couldn't see the forest for the trees! I had the plane sitting flat on the stand while I timed the engine run. I only lifted it a couple of times per run to set the needle and verify a consistant 2-4 break. I feel so stupid! It's amazing how my logic has deteriorated over the years. Take care!
Welcome to that "Logic" thing "CLUB". Lots of us "old-timers" belong there.
A number of CLers are switching to RC Tanks simply because the flow is always there like in an RC model. Scale CL may make touch and go landings, etc. and they don't need the engine quitting as the rules require some taxi where the centrifugal force does not keep the fuel on the side of the tank as in flight.
In addition there are some tanks with a bladder inside where the airpressure compresses the bladder to keep a measure of fuel around the fuel outlet. Have not tried them for CL but probably will soon. For RC aerobatic and racing they are great as designed. As designed they are not good for Touch and Go after the tank is down to half full, or half empty as your optimism/pessimism may determine.
For CL that is a flaw but it can be worked out by using a feed line such as in a normal tank, i.e. a longer feed line with a weighted nipple.
Enjoy!
