Lunak Aerobatic Vintage Glider Plan-Build Part One

[@tonycamplin8607]

It looks like an interesting project that'll keep you busy for a while. With that detailed plan it looks fairly straightforward and not difficult though. Hopefully 2025 will be a good flying year.

[@CliffHarveyRCPlanes]

Thanks Tony, yes, the plan is detailed enough, if only the measurements were as good 😁 Fingers crossed for some good weather this year 👍

[@EssentialRC]

Good luck with this project Cliff !

[@CliffHarveyRCPlanes]

Cheers Dom, and thanks for the use of your inspirational images 👍

[@purcellrcaviationchannel]

Super looking project, Cliff. This'll be a mega-build over many eps, so there's a huge dustbin of popcorn incoming for me. Can't wait for part two!

[@CliffHarveyRCPlanes]

@@purcellrcaviationchannelPerhaps I'll get a bag in as well Gina 😁

[@gudjonolafsson]

Looking forward to seeing this one coming together.

[@CliffHarveyRCPlanes]

A 'proper' build at last Gudjon 🙂👍

[@MarkCroucherRC4fun]

Next best thing to building and flying watching someone else build and fly. 😊

[@CliffHarveyRCPlanes]

If we both watch each other Mark when are we going flying 😁

[@ModelAV8RChannel]

Cliff this will be epic! Really looking forward to watching this series! I like all the changes so far, updating it a bit is a great idea.

[@CliffHarveyRCPlanes]

Thanks Adam, I'll try not to get distracted along the way 👍

[@bobflyman]

Great project, looking forward to following this build.

[@CliffHarveyRCPlanes]

Thanks 👍

[@tonymccarthy9273]

hi Cliff, this looks interesting, one of the appeals of watching or building from plans is seeing a person deal with every problem they may encounter in the build ,

[@CliffHarveyRCPlanes]

Hi Tony, you're right there, different builders find solutions in different ways 🙂👍

[@JeffinLowerAlabama]

Cliff this is a great project and should be an epic glider. I've been changing and modifying the plans on my build too. 🤣🤣😂😂😁😁🙄🙄 Jeff in LA USA

[@CliffHarveyRCPlanes]

Thanks Jeff, I meant to say on last week's Livestream it was good to hear you're cracking on with the build 👍

[@JeffinLowerAlabama]

@@CliffHarveyRCPlanes having some issues sheeting the leading edge of the wing. Can't clamp it and thin CA sets to fast. Going to try letting the PVA glue dry and using a covering iron to stick the sheeting. There is a slight curve on the leading edge that makes it hard to hold the top and bottom of the sheeting.

[@CliffHarveyRCPlanes]

@@JeffinLowerAlabama The iron trick works really well although I haven't tried it personally

[@JeffinLowerAlabama]

@@CliffHarveyRCPlanes used the iron on the sheeting on the leading edge and it worked great, thank you for showing John? use it for sheeting his BIG glider.

Hi Cliff, this is really a build! Looking forward for the build series. 🙂

@@Tom-wl9sx Thanks Tom, I'm going to enjoy putting her together 👍

[@wingman2646]

Great project Cliff. One to watch.

[@CliffHarveyRCPlanes]

Thanks David 🙂

[@downwindchecklist6567]

Looking great! Working with such massive pieces of would must be a real pleasure! I believe Lunak means kite, the bird. It will look great in the air and a great winter project!

[@CliffHarveyRCPlanes]

Thanks Andrew, yes, 'Kite', rather apt 👍

[@IansRCExploits]

Looks like a fab glider, should be wicked!! Looking forward to the build 😀👍

[@CliffHarveyRCPlanes]

She'll look fantastic Ian when she's done, not sure on the colour yet though, still plenty of time to think about that!

[@wearemany73]

This is right up my alley. I love my ASW 28 slope soarer and this one’s going to be a big boy at 1/5th scale. Can’t wait to see this come together. 👍

[@CliffHarveyRCPlanes]

Thanks for watching and commenting 🙂

[@paulwoodman5131]

I like the size of this. It's big but it still fits on a standard workbench. It's not like you have to build it in a garage. But that guy that has the rubber powered model in his garage is amazing. 😅

[@alanreynolds2125]

Enjoying this one Cliff👍✈️

[@CliffHarveyRCPlanes]

Thanks Alan, it's a big build but so satisfying 🙂

[@jonjepson3650]

Knowing you Cliff there's no way that will take you all winter, you will have it done in no time 😂

[@CliffHarveyRCPlanes]

Perhaps Jon, although I don't want to rush it 😁

[@paulroth6525]

That looks like a really nice one Cliff. I'm going to follow this build with interest

[@CliffHarveyRCPlanes]

Thanks Paul 👍

[@glynmatthews6697]

If this is this Mick Moore Lunak plan -I bought it years ago so this may spur me along to build it! 👍🏻

[@CliffHarveyRCPlanes]

It is Glyn, I'm changing the building methods to bring it up to modern techniques though, cheers

@@CliffHarveyRCPlanes cool stuff Cliff, looking forward to watching the progress, I know how long this stuff takes though so good luck!👍🏻

Looking forward to this one..

She's pretty cool for a 75 year old design Eric 👍

[@johnmacdonald5610]

Love watching, how did you cut the light ply? Do you have a laser cutter?

[@CliffHarveyRCPlanes]

Hi John, I do, but drawing the files to cut from a plan that turns out to be not that accurate isn't very efficient 🤔👍

[@diceman2004]

Man theirs a nice look , almost seems like it needs a jet engine in it .

[@CliffHarveyRCPlanes]

I think so too considering the design is 75 years old 🙂

[@SlopeFlyer001]

Great video, and excellent build skills, Cliff. Maybe I have missed it or overseen it in the comments. How did you transfer the plan into the laser cut software to cut/laser the fuse frames? Thanks for clarifying.

[@CliffHarveyRCPlanes]

A long process, photograph the plan, trace every component on the screen manually changing almost every dimension, export into the laser software rearranging the files into an efficient order and then the easy bit ... pressing the start button. Then finding the original drawing isn't very accurate! I'm up to part nine of the series, enjoy, cheers 👍

[@SlopeFlyer001]

@@CliffHarveyRCPlanes , thanks very much. Great video series. Learning lots of new things and will now dare to start a balsa project. First a glider based on a kit, and if I finish it successfully, a glider build from scratch 😄.

[@billebdon4338]

Cliff I think this is the same plan as a clubmate of mine built a few years ago. It flies very nicely but is not very aerobatic - the roll-rate is rather slow. He used flaps as well as airbrakes and, like you suggest, they would have been better with servos in the wings. So you might want to modify the wing section. If you need further info let me know and I will send you his contact details.

[@CliffHarveyRCPlanes]

@billebdon4338 Interesting Bill, do you happen to know if he coupled the flaps to the ailerons?

[@billebdon4338]

@@CliffHarveyRCPlanes I don't think so but I have contacted him to put you in contact. I'm sure he would be happy to give you his experiences with it. If you search KZbin for "Petes Lunak" you will find a couple of videos I did for him.

[@andrewdouglas5939]

Hi Cliff , exciting new project . I ha a standard Cirrus waiting to be built. Could you elaborate on how you cut the formers ?

[@CliffHarveyRCPlanes]

@@andrewdouglas5939 Hi Andrew, I would have traced them onto ply and cut them on my jigsaw, it would have taken a few hours. However I want to become more proficient at using cad software so I spent a lot more than a few hours on the computer and just a few minutes running the laser!

[@andrewdouglas5939]

@@CliffHarveyRCPlanes thanks Cliff , could you tell me which model of laser you have and what power it is rated at

[@memememe2674]

Cliff, did you draw the formers by hand and cut or drew on pc to laser, if the latter can you shiw how that's done would be interesting to see that

[@CliffHarveyRCPlanes]

I did the latter, I may have filmed a part of the process, I'll have a look 🤔

[@peteronel4051]

Hi it is the most perfect way to build a glider I am busy with one but come across a problem which unbeknown to you you have just solved and here is the question where do you or did you get the adhesive which first you apply whet than dry and than “HOT IRON ON” I would be very grateful if you could help me out with a address. I am in California USA and it sounds as though you are in the UK by your accent. Regards Peter Onel

[@CliffHarveyRCPlanes]

Hi Peter, yep, British through and through, the glue I'm using is called Speed Bond by Deluxe Materials but you may want to do a test piece with any white glue, Gorilla Glue also works well I believe. Here's a friend of mine trying it for the first time kzbin.info/www/bejne/f5qykIh6fp5osMUsi=zIBzhBIjF6gzHy49
