I have a JL L-39 that is ready to be flown today or tomorrow but have a couple concerns.

I currently have the stock tailpipe installed with a bell mouth and no bypass. The outter part of this tailpipe seems awfully flimsy and thin. The inner pipe is only approx 3/8" shorter than the outter pipe at the aft end and I am concerned if this is enough of a length differance to get a good venturi effect ? I made one short run ( 30 seconds or less) at primarily idle and low power, and afterwards the aft fues exterior was a little warmer than I am accostomed to.

Does anybody have any experiance good or bad with the stock tailpipe on this airplane ?


Secondly the fuel tanks dont look very big capacity wise. I have a 35lb thurst class engine installed and would hope to get atleast a 6-7 minute flight with reserves for a couple go arounds. Are these tanks big enough for that with that sized engine ?

Thanks

E.N.T.

I fly with the stock pipe. No issues, working well.
There's enough space on tpo of the tanks to place
another.I think you'll need an extra one.
