    Then the servo end…….

    Next the fuel tank was installed. Important to get the feed line close as possible to the same height as the throttle needle valve on non pumped engines….

    Next up was the tail wheel assembly……shown in position not yet glued. Unusual arrangement on this model with the linkage controlling both the tail wheel and the rudder.

    The instructions call for the tail wheel plate to be glued on at this point but I’m leaving it for now for a couple of reasons. Firstly I want to wait until I know the final position of the rudder and secondly the fuselage has to be heavily shaped to get the correct scale appearance. Its currently square but needs to end up looking like this……

    Next the wing was clamped into position and the positions for the wing mounting bolts marked for drilling…..

    The holes were then drilled and the wing mounting plate T nuts fitted and the assemblies glued and clamped into place….

    More soon…..

    Glad you said about the feed line, I was thinking to have the bottle backwards.
    the build really looking good.

    It needs to be as close as possible and the feed line of the tank needs to be more or less level with the needle valve as shown below…..

    Too high, the engine will flood, too low it will run lean. Its not super critical to get it exact as the tank will be pressurised using exhaust pressure but it all helps and on this model there was tons of room to adjust it. Might be different on your Tiggie……

    Ian how will this work with the Tiger, as my engine is upside down.

    Exactly the same. It doesn’t matter about the orientation of the engine as long as you keep the level of the tank/needle about the same. The picture below shows a four stroke set up similar to yours/mine….just imagine the engine flipped upside but with the line from the fuel line to the needle still being level.

    Wing locating dowels fitted and centre section boxed in. Wing bolts fitted along with strengthening plates.

    Cooling air scoop assembly made up and glued in place. Plane calls for centre section to be removable for tank access but due to how I’ve mounted the tank it’s not required so glued in place. Since doing it, I may have a think on how much access I need for the tank……food for thought.

    Strengthening beams added between F1 & F2 as per the plan. Again I may rethink this and possibly have a top hatch depending on where I have to put the battery.

    Such talent you have sir. It’s really coming together.
