    I have had a couple of small warbirds a while back. One thing I found out fast small war birds are always over weight and difficult to fly. If I built another war bird it will at least 90 inch wingspan.

    Well all I need to do is build one more wing and aileron, then all the wood work will be done. Then do a assembly and see how it all fits together.

    Scale it up to 70-72" span should work well for something in the 30cc range. The 55cc version I built had a 80" span and was perfect. Honestly the 80" would probably fly just fine and still have good power on a 30-40cc just more fun to have ballistic power.

    Looks great. Yes add the extra bracing. Flat plate surfaces of this size can really start to flex and twist a lot under load.

    The wing is all set up just have to do a final check to see that everything is straight and square.

    For some reason I have a small lift in one corner. Will have to work on that, hopefully when the sheeting is done I can remove that. Only part that concern’s me if 1/16 sheeting has enough strength to remove the small lift in one corner.

    Got the front sheeting on and the wing looks like it is dead flat right now.

    The sheeting on the one side is almost bone. The servo opening is in and is fitting like it should. Just have to do the cap stripes and then this side will be done.

    Bottom is sheeted and all done. Flipped over cleaned up everything and epoxied the wing tube in from the bottom.

    Making progress slowly the leading edge sheeting is on, just have to wait a while for the wood glue to dry then I can finish off the centre sheeting.
    Was planning to install the ignition into the leading edge of the wing but after thinking about it for a while decided not to do it. Just to much work.
