Hanky Planky Foamy Woamy

[Graham Davies 3]

This is great Ron. When I first discovered Foamboard I floated the idea of a similar thing at our tiny club. I love the idea of low key competition to give a focus to the banter and mickey-taking, and if you remove the risk of someone breaking a treasured model, it's even more fun.

 

Sadly, this year I failed to locate any shape of 'Tuit', never mind a round one...

[Ron Gray]

TBH I don't think we would have had the take up if I hadn't produced the 'kits' but as they are only £30 for the cut foam parts, the CF spar and the motor it would appear to be too good an opportunity plus the various rounds of my Wacky Races has met with enthusiasm too! Our first round is in April at our season's launch meeting so we'll see how we all get on, final results in October.

[Ron Gray]

A few people have asked me what I’ve planned for the Hanky Planky Wacky Races - if you look further up this thread you will see where I’ve referenced my club’s website page showing the details.

Further extensive test flying has brought to light an interesting characteristic with this model. I was testing out the glide performance but decided to try it inverted, wow, the rate of descent was much less than the right way up and it was very controllable right down to the stall which was benign, with a wing rock and sink. So I now have an idea of how I will fly in the ‘Viagra Challenge’.

Thanks @Ron Gray😆

I shan`t tell if you don`t.

@Bruce Collinsonhas contacted me about obtaining a 'kit' of this Depron version of this brilliant model, so it got me thinking does anyone else want one too? Kit contents as follows:

 

The kit comprises all the main parts in 6mm Depron so:

 

Fuselage sides, top and bottom and strips of 6mm sq. Depron for extra gluing area when joining fuse sides to top and bottom.

Wing - 2 layers of 6mm with C/F spar.

Fin and rudder.

Tailplane and elevator.

Overlander motor.

You need to provide balsa and ply for fuse doublers and formers.

You need to provide all hardware and radio equipment, servos, esc.

 

All the above for £33 plus P&P. (Got to see how much cardboard boxes are to protect parts for posting!)

 

If there is sufficient interest I'll put a 'For Sale' ad up.

 

The basic build instructions are on my club's website, shown in a previous post plus the rules for my Hanky Planky Wacky Races competition which means that we could make this a national comp. Who knows, it could be a laugh to combine this with the BLMRA 2023 World Record attempt and see how many Hanky Planks we can get flying at once!

[Kevin Fairgrieve]

My feeble attempt is ready.

 

Made from one of @Ron Gray kits and using the motor supplied along with a 3S 1350 LiPo she tips the scales at 514 grams.

For covering I used some "Wing Tape" that I purchased when HobbyKing were having there closing down sale in the UK warehouse.

On top of the tape I used document laminating film. Hinges are a mixture of film and Mylar. I have also reinforced the hinge lines with fibreglass tape.

Maiden as soon as the weather allows.

A beauty Queen she is not!

Excellent Kev, bring on the Wacky Races!

Hi Ron

 

Just got hold of the Balsa plan, but I am going ahead with the foamboard version. I'm off to the model shop soon and wanted to confirm the c/f spar, is it 6mm, or 5mm, tube, 

And is gorilla glue clear the best stuff for sticking depron/b & q foam or artists foamboard, I have just about every other glue in the market, but I don't have Gorilla glue clear. I have checked and my local diy store has it in stock so I can get some if its beneficial to the build.

 

Thanks

Hi Steve

 

The C/F tube I’ve used is 5mm dia. Regarding the glue, I used Gorilla Glue clear on my original build mainly because I really like it and it spreads very easily. The downside is that it takes a long time to set so I left parts overnight to dry which obviously slowed down the build time. On the KFm-2 profile wing I made I used UHU POR which can be a bit hard work to spread thinly, I used a wooden spatula and worked it hard to ensure that I had a very thin (ends up looking like a sheen on the surface) coating on both surfaces then let it dry for 10 minutes before bringing the parts together. With this glue the built time is dramatically reduced but you only get one go at aligning the parts! Others in my club have used pva, superphatic, Gorilla Glue Brown and expoxy. I suggest you try your preferred glue on some scraps and see how you get on. I need to build a new Hanky as I broke mine (fuselage) and I will be using UHU POR throughout, the aim is to build it in an afternoon!

 

My Wacky Races inaugural round is in just over a couple of week’s time so I need to get mine rebuilt and beautified!

Thanks Ron. 
 

I’ve bought a tube of gorilla glue, and had a go with it on the wing. When you are sheeting the fuselage, I see you cut full-size taper sheets for the full length of the fuse, but will it be structurally acceptable to use scrap 3 inch pieces as you would if you were using cross grain 3 inch balsa sheets? It just seems daft not to use the left over bits if you can. If not it’s not a problem as I have plenty to go at. 
 

thanks

Sorry Steve, I don't understand. If you mean the balsa doublers then these are not full length, they only go back just past F2.

[Steven Hurd]

Sorry Ron, 

 

I meant the top and bottom depron sheeting that goes from the rear of the wing to the tail plane and the same on the underneath. 
 

I confused the point by saying that on a balsa model we would normally cross grain sheet this area with 3 inch sheet balsa, or that’s what I meant to say. 

So what I mean is can you use up scrap depron to sheet this area, or would that make the fuselage structurally unsound compared to a depron sheet cut for the full length, as I think you show in your build pics 

 

thanks

[Ron Gray]

Thanks Steve, now I understand. No reason why off cuts can’t be used for the top and bottom of the fuse and it won’t impact on the strength.

[Steven Hurd]

Ron 

 

Thanks for the the help. 
 

I have just gone into the workshop to have a look at the bottom of the wing, I used gorilla glue for the first time. I glued the 5 mm carbon spar to the bottom wing, but it has come up with a new problem when using this glue that I haven’t encountered with any other glue. 
I used cling film under the wing to stop it sticking to the board, guess what it likes cling film almost as much as the stuff I’m trying to stick, it’s made a right pigs ear of the bottom of the wing, have you any tips for what can be used to prevent sticking to the board, or should I just use another glue for this and just use the gorilla glue for foam to foam, where there’s no chance of sticking it to the board. 
love this modelling, whenever you try a new technique there’s always a learning curve, every days a school day. 
 

thanks

@Ron Gray Where did the fuz break? Is this an area that needs to be a little more robust?

Of course if it was broken in a vertical tent peg 🤔 

[Ron Gray]

@AceI’m afraid to say that it was a case of a tent peg manoeuvre that I completed successfully! I have to say that the foam built Hanky is very robust, in my tent peg manoeuvre the fuse, back to F3 was crushed but that was the only damage, the tail mounted servos were forced out and the wing broke free but nothing else! Bearing in mind that the fuse had already been rebuilt following my over zealous ‘spin of death’ test (trying to better 13) I’m well impressed!

 

Result of ‘spin of death’

 

[Kevin Fairgrieve]

My maiden is tomorrow!!

Along with the Sirius if the weather plays ball.

[Ron Gray]

I’m going to try and get up to the field tomorrow but it won’t be until the afternoon, so don’t break them before I get there! Looks to be a bit windy but that won’t worry the Hanky!

[Steven Hurd]

Re did the wing but this time I’ve used grease proof paper, hope this works better than cling film. We will see tomorrow. Then it’s on to the fuse sides. 
 

Great fun when the weathers no good for flying. 
 

Steve 

[Ron Gray]

You can always use parcel tape!

[Steven Hurd]

The grease proof worked a lot better, though I did spray it with silicon polish first, it did try to stick but came off very clean. 
 

So do you mean I can cover the blemishes with parcel tapes or the glue doesn’t stick to the parcel tape. 
 

Thanks for your tips they may seem simplistic questions but they are very helpful when answered. I’m having a great time using foam for the first time, and I think it may have a future in my modelling room. 
 

Steve 

[Ron Gray]

You can cover the whole plane with parcel tape!

[Ron Gray]

Another Hanky joins the fray, and what a beauty it is (the 'plane that is not its creator Ian who could do with a good haircut if you ask me). And, yes, sunglasses are obligatory to fly this one!!!
