Whatgoesup.... Posted January 19, 2016 Share Posted January 19, 2016 So eventually, albeit much later than planned, I've managed to make a start on my contribution to the MB. Whilst my build has been delayed it has given me the opportunity to watch and learn from other builds - and wow what progress you guys are making !! The variations being built and the techniques used are most impressive - if mine turns out half as good I'll be made up !! My Ballerina is going to be very much as per the plan - sheet tail feathers, single servo & bellcranks for the ailerons and this little beauty up front providing the grunt ! - Quote Link to comment Share on other sites More sharing options...
Martyn K Posted January 19, 2016 Share Posted January 19, 2016 That does look nice. Good luck with the build and before you get too stuck, don't forget we are here to help Martyn Quote Link to comment Share on other sites More sharing options...
Whatgoesup.... Posted January 19, 2016 Author Share Posted January 19, 2016 First job was to make room on the bench by moving the most recent project (inspired by the weather) backstage !. I've decided to make a start with the wings so after splashing out on a new piece of plasterboard pinned out the first panel. Quote Link to comment Share on other sites More sharing options...
Whatgoesup.... Posted January 19, 2016 Author Share Posted January 19, 2016 Thanks Martyn, I will certainly be needing guidance for sure - I'll be using you guys as my online instruction manual if thats ok ! I opted to cut the wing ribs using the sandwich method - don't know if I'd do that again - created a bit of a monster to work with but with much trimming and sanding got there in the end !

Whatgoesup.... Posted January 19, 2016 Author Share Posted January 19, 2016 Pinned down the lower sheeting and spars etc and started putting all the bits together - one variation I did make from Peters process was to pin the lower capping strips to the board before attaching the wing ribs - with hindsight I would like to have had all of the lower sheeting pinned down as Chris had done to keep it all nice and flat - but heyho you live and learn ! That's where I'm at for now - nothing earth shattering but at least I'm back in the game ! - if it looks like I've got anything wrong or out of place please make comments - as I've said before you guys are my reference manual !

Martyn K Posted January 19, 2016 Share Posted January 19, 2016 Possibly a little late now, but if you are using the sandwich method, I would advise cutting the templates - one each end - out of 16g aluminium strip so they don't get sanded away while shaping the blank Following on from your last post. You just need to be careful that you can still see the plan. If you are going to cover things like spars and ribs, extend their positions by drawing on the plan so you can track backwards using a straight edge or square for alignment Edited By Martyn K on 19/01/2016 12:21:42 Quote Link to comment Share on other sites More sharing options...
Whatgoesup.... Posted January 19, 2016 Author Share Posted January 19, 2016 That was why I didn't pin the lower sheeting down initially - because I was uneasy with it hiding so much information on the plan - but it seems a much better idea to do it now as the bottom of the wing is flat and the board will keep it that way. I think I'll try it on the other wing, as you say Martyn make some reference points to transpose on to the upper face of the sheeting and build up from there, Thanks.

mightypeesh Posted January 19, 2016 Share Posted January 19, 2016 Looking good. Dont worry about being 'belated', it's going to be a good four weeks I reckon before the building board is clear for mine.... I have got the engine though! Nice little boat by the way, Cheers, Simon Quote Link to comment Share on other sites More sharing options...
Whatgoesup.... Posted January 19, 2016 Author Share Posted January 19, 2016 Thanks Simon, its an Aeronaut Diva all laser cut parts goes together like a 3D jigsaw It's good to know I'm not alone behind the leading group, I'll probably still be on the wings in four weeks but hopefully the second panel !

john stones 1 - Moderator Posted January 19, 2016 Share Posted January 19, 2016 Hello WGU Another 4 stroke, I'm starting to feel jealous John Quote Link to comment Share on other sites More sharing options...
Whatgoesup.... Posted January 19, 2016 Author Share Posted January 19, 2016 Hi John, I was just admiring the work on your thread, can I ask does your wingtip sit level with the bottom of the wing ? the construction of it seems to be raising a couple of issues but looks as though yours is spot on !

john stones 1 - Moderator Posted January 19, 2016 Share Posted January 19, 2016 No, there's a view on the plan along side the dihedral brace, that gives you the positioning. John Quote Link to comment Share on other sites More sharing options...
Whatgoesup.... Posted January 19, 2016 Author Share Posted January 19, 2016 Thanks John, I'll check it out later - I keep forgetting there is a lot more information on the plan besides the small section I've cut out and got pinned to my board !

Chris Barlow Posted January 20, 2016 Share Posted January 20, 2016 If you intend to pin all the 1/16 parts to the plan first when building the wing I recommend taking a few photographs of the plan to refer to! A few nice Saito's going into some builds too! I think the Ballerina definitely needs that 4 stroke soundtrack to it! These electrickery lads don't know what they're missing!

Whatgoesup.... Posted January 20, 2016 Author Share Posted January 20, 2016 Absolutely Chris, its got to be IC for me every time - this is my first four stroke can't wait to get it running ! I'm working off a copy of the plan so I have the original beside me - providing I read it properly should be ok ... I think transposing the reference lines accurately onto the top of the 1/16 sheet is the secret ! Quote Link to comment Share on other sites More sharing options...
Craig Thomas Posted January 20, 2016 Share Posted January 20, 2016 What size Saito have you got WGU . I have a Saito for my ballerina. Again, the same as you. This will be my 1st 4 stroke. They sure seem like good quality engines. 👍 Quote Link to comment Share on other sites More sharing options...
Whatgoesup.... Posted January 20, 2016 Author Share Posted January 20, 2016 Hi Craig, I've got the little FA40 for mine, I see from you're thread you've gone for the bigger one - Not heard any bad reports about them if they go as good as they look I'll be well happy, not to mention the sound and the smell !! Hows your build coming on ? Quote Link to comment Share on other sites More sharing options...

Peter Miller Posted January 20, 2016 Share Posted January 20, 2016 Oh Good! Another one and with a civilised powerplant. As I have said I will go electric when airliners do and when I see an aerobatic dispaly with a full size electric powered PItts Special...with Smoke on!! PS THat is one of our club members giving us a little show before coming back to the field with his models Edited By Peter Miller on 20/01/2016 21:40:02 Quote Link to comment Share on other sites More sharing options...
Whatgoesup.... Posted January 29, 2016 Author Share Posted January 29, 2016 Looks the part Peter ! So I've made slow progress on the first wing panel but by adopting Peters "Purple Plan" I think it's now at the stage where I can lift it from the board and start on the second wing this weekend. It's just another wing - others have made better I'm sure and definitely quicker so theres not too much to say but I did have a couple of "oops" moments which give it an individual touch . . .

john stones 1 - Moderator Posted January 29, 2016 Share Posted January 29, 2016 Looks very good to me and I see you've left l/e over the end ready for the tip to glue to, and you've tidied board up for the photo shoot. John Quote Link to comment Share on other sites More sharing options...
Whatgoesup.... Posted January 29, 2016 Author Share Posted January 29, 2016 Oops No. 1 = When I made the ribs I obviously didn't taper the rear to a fine enough point. As a result the 1/8 x 3/8 TE was too thin to make a decnt joint leaving a large step where it attached. To compensate I went up a size to 3/16 x 1/2 TE which fits perfect but the wing is now slightly deeper. So would it be best to trim the TE back or just leave it and make the tip slightly bigger too ?

john stones 1 - Moderator Posted January 29, 2016 Share Posted January 29, 2016 Shape/sand it back or it wont fit the fuzz correctly, it's nothing critical just do how it looks good. John p.s that's not an oops either you saw a problem and dealt with it Edited By john stones 1 on 29/01/2016 11:19:55 Quote Link to comment Share on other sites More sharing options...
