"Bruce, today I made the first two flights on my modified Vortex. Thought I would send a couple of pics in case you might be interested in how one of the many mods of your kit looked. I was really lucky that the kit assembled very straight. No twist or out of true in the wing at all. I only needed three clicks up trim after take off to fly hands off. During construction I moved some things aft, used hardwood and epoxy aft of the cg in some places(because I knew it would need some weight aft) which resulted in a 21 1/2" CG with no added weight. I presently have one of the Delta Fighter 90 ARFs and didn't like the accessibility associated with the single panel underneath. I built three access panels on top. These hatches have hardwood frames and sub spars that run from W-2(L) to W-2(R). One hatch is for the tank, second for the servos, and the third magnetically held hatch covers the air receptacle and charging jack/elec switch. Under the mount for the air receptacle and elec switch is the receiver and air tank."

later, Ron sent this update:
"I built one of your Vortex planes this summer. Mine was built with retract gear so the tank went behind the standard tank location. The short of a long story is that two successive OS 91 FXs, one with Cline fuel pressure regulating system did not perform well. Fuel delivery problems. I recently bought and installed a new YS 61 two-stroke pumped engine and installed a new JR 2.4Ghz system. The new combo is flying well. And even though I wasn't successful with the OS91, the YS61 pumped engine does just as well. Good flyer."
