polyhedral wing

This one for the build experts I think???? I am building from a plan a 1/6th scale Bird dog L-19, Bill expertly cut all of the formers and rib on his Infernal Machine for me. My problem is.....wing is polyhedral, wing is one piece (72" span), root angles are fine, clamped up tip sections for outer angle yesterday, glued them up.. This morning removed clamps and wedges etc.. measured wing tips in relation to each other and found that one side has 1/8" more dihedral than the other (Must have had a senior moment yesterday), now the question is 'is this difference very important, I have no problem with cutting out the glued formers and starting again, but only if really needed. Many thanks for sensible answers.

Thanks

Michael

Hello Michael nice to see someone doing a build to be honest i would not worry to much about a small build problem like that, its a one off you don't have all the jig's model manufacturers have to get things spot on, a little trimming in flight and I'm sure it will fly a treat good luck keep building

At that wing span, I really don't think 1/8 will make a noticeable difference at all, crack on with the build and give us all a taster of things to come with some pics when you can!

Hi Michael
Nice to see you have started the build and as John as said don't worry about the 1/8 on the wing it wont make a lot of difference.
You will be able to check it against the full sheet drawing as i have two sets coming this week!! just in case some one want's to build it electric
it will be a nice model .

Thanks for the very time saving info, just as I thought myself, but had to get it confirmed by those with greater experience, as for pictures here are 3 showing progress so far, basic fusilage, to make sure wing seat will fit??

then the wing as it is now with flaps in place, . and last the horizontal stab and elevators with fin and rudder.

its coming along nicely, really enjoyable, have to share the garagr with car and other items, so gets a bit difficult.

thanks again

Michael

Well done, that all looks really good, but if you don't mind me saying, your lucky sharing a garage with a car......
I have to share a house with a wife!!

Found this thred on it, ok may not be the same size.

Thats gonna be nice Mick and wish i had the patience for a total build, takes me forever to put together an ARTF as you all know

At least you have some room in your garage left to work on your models, i have bits all over the place like dining room,conservatorry,shed & garage but always nice to be able to leave it all out in one place


Good luck and keep em comimg

Mike Not seen any posts for a while! hows the build going? still on tract?

Well its getting there slowly,,


had to modify the firewall, hole much too big, cut a 1/4 ply piece and epoxied in with a couple braces behind.



Wing nearly done, all sheeted, aelerons dry fiited , flaps still to do, holes you can see are fore strut fittings,



Servo covers all made, strings are inplace, put in before sheeting completed.

Fuselage sheeted, blind nuts fitted foe engine mount and tailwheel.





Under carriage 90% done, am in process of contructing removable hatch to give access to UC and servos which are fitted in lower half.


Thats all for now, I do a little each day when I can, nearl reached the covering stage,??? then the fun really starts?????

Hi all, at last, its nearly ready to fly?,,,final build has ended up a bit over 'planned' weight, and needs 1/2 pound of lead up front to get CoG correct, so hoping that the 52 FS has enough grunt to get it in the air, have not completed the cowl yet incase I need to fit a bigger power lump, and decals will be added later after one of our club's 'Trubshaws' has put it through it paces. The worst build bits was definately the glazing, front and rear screens a right royal pain. Looks OK from about 20 feet away.
Just controls to set up and run up the engine, then I will be down the patch for a maiden.


Michael

Looking good Mick and well done for making the effort to post the pics...look forward to seeing her fly

She's looking grand, well done you, I reckon you must be chuffed with the results of all your efforts. If the 52 struggles give Phil a bell, I think he's got a looser 300 twin that might just cope ..

That 52 with an APC 12 x 6 will do the Bird Dog proud!!

Well done Mike you have made a nice job are you going to put any decals on!!

Thanks for all of your comments guys, I have taken Ian's advice and ordered a couple of 12" props. Decals from Pyramid cost about £30, so just thought I would wait till it gets in the air and down again safely. I must admit the red and white scheme with black decals will look brilliant. Thanks again.

Hello to all,   2013 not a good year for me, at last got my ails under control, now my wife is recovering from an eye operation. So I hope to be down the field very soon, must be very rusty on the sticks at present. So have completed my plan built bird dog at last and the ARTF Decathlon is also ready for a maiden, a few pics here......

Dynamic duo there mate  That bird dog has turned out terrific   Good luck with the maidens  

I've never had any luck wiv the maidens??


if they fly as good as they look you should really enjoy those Two!
 

Two nice models there Mick and hope to see them at the patch real soon    
wishing Doris a speedy recovery too mate  

Take care
