"I have to tell you how happy I am with the bladders. I flew one hour. No more fuel imbalance! The vents work well. Both tanks drain equally. Nice to land after 45 mins flying and have more fuel than I use to have."

"Just to let you know the engineers at Sheltam completed the conversion last Friday and we flew the a/c today. What a difference - more RPM on Take-off, in the cruise at the same power settings as we used previously (70% RPM & 7 MAP) we got 25 km/hr more cruise speed. Aerobatically the vertical penetration is definitely noticeably improved too!!! Your convex really makes a difference - engine runs smoother with less vibration and less of that cyclic resonance that these Vedenyev M14P engines seem to suffer from particularly at 80% RPM. Starts are almost immediate too. All in all a marked and very satisfying improvement - THANX VERY MUCH INDEED!!!"
"The CI is finished on my CJ and I got to fly it
yesterday. Before that all we did was test runs on the auto-plug
conversion. I have to say the engine runs smoother, can smoothly idle
below 500 rpm (smooth even at 400) and at WOT, the engine runs over
redline (by about 50 rpm) so it must be putting out a bit more power
than with the Chinese plugs. I have a very slight hint of ignition
noise in the background but nothing that the squelch can't handle. I
am very pleased. My wallet will be pleased each annual too. The
conversion will pay for itself in a few years."
