Another note on the F22. When I checked the air intake requirements for the X45 I found there was more than enough flow moving past the 32 oz. tank. So I decided to block off the two cheater holes...

Yup, it was one of the reasons I went with the Xicoy. I already have one mix for a couple JC Rabbits and another for an AceX 80. I can use the AceX blend in the Xicoy. I didn't want a third

The 32 oz. Dubro tank fits pretty well. Back of the tank sits against the spar and the front against the aft end of the cockpit area. A quarter inch shim/bracket above the tank makes for a snug fit...

Well the turbine mount is done. Gotta say Gary, that your mount design makes a very solid platform. I had milled glass, micro balloons and 30 minute epoxy on hand so used that. Guess that might be...

Gary, I wonder about your weight and balance on the F22 after you added the JP brake set. I saw about an 8 ounce increase when switching to the JP's. and that is aft of the CG of course. When I did a...
