    Hey guys thought you'd like to see some pics of a set of wings I'm building for a customer in Texas. Tony has come up with some pretty trick upgrades to our wing kit. CF aileron coves and leading edges to compliment the tips. Both lower wings are on their way to the customer and now to start on the upper. Between these, our other parts and the WP-360 development we've been pretty busy at the shop!

    The WP-360 is one of my dream ships. The wings are absolutely beautiful, as usual from you.

    Wow excellent! Can't quite tell from the pics - are those solid or laminated spars? I read somewhere that laminated spars are XX% stronger than solid spars. I wonder what the cost/strength tradeoff would be.

    Also I'm wondering what is the repair like on the carbon tips if you happen to drag a wingtip on the runway? I happen to uhhh.... know someone who... uhhh.... did that once.

    Nice looking wings!

    Will the carbon parts be a part of the standard kits going forward or an option? Are they intended primarily to save weight or to help make the aileron and cove geometry more uniform?

    One of those wing kits is something I'd love to build someday.

    Solid spruce spars. They only need to be "strong enough". You could make them from laminated spars, with flying and landing wires twice the size and hardware 3 times the size but the wing attach fittings, engine mount, tail ect, are still +6-3....... Drag a wing on the runway....... Don't do that :D.

    The aileron coves are an upgrade to our wing kit. The rest is standard. The carbon coves saves a lot of work building and installing them. And yes they are lighter...

    For the air show guys such as sean tucker how is he able to be in the range of +10/-7 gs?

    Tucker doesn't fly an S1. His is the wolf pro which is a steve wolf design that is S2 sized and beefed up.

    My guess is if you want +10/-7 you best design it from zero? Beefing up an existing design will likely result in weight gain like a snowball rolling downhill as Chris suggests in post #6.......add here, more there, then some more over there.......


    Beautiful wing. I've often thought if I came into a huge pile of $, I'd build a Pitts or ?, cover it in a clear something and hang it in the great room.

    I understand that I was just curious in what areas the airframe would need to be beefed up besides the wing to be able to withstand those forces. I understand skip stewart originally modified a stock S2 so I as curious in what areas of the airframe would modifications be needed

    The way I read your post, it was about comparing the S1 wing limit loads to the loads tucker puts on his plane.

    For an S2S, I can't tell you what skip has done to his. I can tell you what was done to bulldog I and bulldog II. BDI was nearly completely stock fuselage frame. Mods to the frame were:
    Beefed up wing attach points upper and lower
    Beefed up bolt in cabane strut attach points
    Beefed up tank attach points
    Many tubes broken and repaired.
    Stock engine mount
    Stock gear
    Stock control system
    Doug fir spars thicker spars
    Reinforced ribs
    3 hinge ailerons aluminum
    Double latching on canopy to keep closed

    On bulldog II, I added tubes to the fuselage to reduce twisting. These can be seen in cockpit pics. All beef ups learned and done on bdi were done to fuselage
    New tail
    5 point engine mount
    Canopy secondary latching
    CG change
    Wolf wings with more ribs, high strength drag wires, etc.
    New carbon cowl styled like bdi cowl but more efficient. Cooled better than wolf cowl and bdi cowl but kept bulldog look.

    The lists above are just what I can think up sitting here and only able to type with one hand( shattered my left wrist). Steve wolf took all of this and the many years of flying by tucker Jim etc into account on the wolf pro design as seen in the plane he built for Wyche Coleman and after that, Tucker's parts that became his new plane mostly built by Tony. These airplanes like all of them are a system designed to meet a mission defined by the designer. Guys who are at the level of tucker need special machines. It takes years of experience to learn how to create such machines just as it does to make war planes, great smart phones or the perfect Omlet. This is why airplanes should never be flown beyond the designer established limit loads unless you are the designer and know every detail. Some mods made by amateurs are scary and without sound engineering. Some pilots fly beyond the airframe limits which is also scary. No level of preaching or chastising seems to be able to stop this. So odd to me how many pilots state they can't afford the right plane for how they want to fly yet they are willing to pay with their life doing dumb Sh!t in a less than capable plane. Sorry, I know far too many dead acro pilots I guess.

    Thanks. On the plus side, I now have titanium in my wrist so I can be as cool as the planes that get the titanium parts. 😜

    Be careful! Remember, when you make something stronger,it just breaks somewhere else.;)

    Ok Kevin, someone's gotta ask since we are a bunch of biplane gear heads...so how many pounds do you think you saved by going with titanium pins in your wrist vs. steel?!?!?

    : )

    I need to get back to work building the top wing ribs on our wolfpro S-1 wingkit after drooling on those pics. Had to take break from it due to work and other stuff that came up.

    Not sure Josh. But the titanium is 48% lighter than steel plus they anodized it for a cool look! Check out the lightening holes too!
