The snow is here! Lets build landing skis!

Howdy folks,

The UK has been hit with a vicious cold snap, though I reckon if last winter was anything to go by it'll be more than just a snap!

At first I was dismayed as I thought I wouldn't be able to drive to my local flying field (a few miles of lanes and tracks, and I don't have a 4x4!) It then occured to me that the usually unfliable fields on my doorstep no longer have sheep in them and I can fly there again. The farmer has known me since I was a toddler and as long as no sheep are out he doesn't mind me flyinhg. So, as the fields are covered in snow I thought I better make me some skis!

Does anyone have a good plan for park flyer sized skis? I've just bought a Multiplex MiniMag for general fun-flying, and it's the perfect candidate. Can anyone suggest suitable materials, and design considerations? Dubro make park flyer sized skis but I can't find a UK supplier, but to be honest I'd love to make my own. So, has anyone built them? I'd really appreciate pointers .

Will.

There's some good info on skis here: http://flyinglindy.homestead.com/skisandfloats.html

The main thing to remember is you want the tips of the skis to be angled upwards in flight so they don't dig in when landing. Floats actually work very well on snow, too. While snow flying may be a novel concept, I have done it a few times and the novelty wore off as quickly as my fingers turned blue!

Have fun, that's the main thing!

Thanks, there's some great info there . I may stock up on thin ply tomorrow - if the night doesn't bring too much more snow! In these parts, when it does snow, it generally doesn't get too cold. Providing the wind is calm you can be outside comfortably for long periods in normal winter clothing. Winter slope soaring may not be my cup of tea though with the additional wind chill and general hiking involved, I may wait for those balmy spring afternoons before I start flying the sailplanes I've built recently.

Will.

Skis for the YAK AIR-1

Even Peter Rake's recent prototype I built had skis! They just removed the wheels and fitted the skis - with some sort of restraint/bungee at the front..

Winters are windy here in the midwest US.
I don't think in 20+ years of RC modeling I have gotten more than 1/2 dozen decent flights in. I just try to keep my thumbs "nimble" by flying my Blade mSR around the living room.
I work the days/times we have indoor flying here.

South Wales already?
I went to look at your location, and was expecting to see Minnesota or something. We have had lousy winters lately, and haven't had snow yet.
There was a nice flood at the park field today, and was ready to maiden a recently competed seaplane or two, had there not been cyclonic like winds. I'm waiting for a nice snow, to try them out in.
BTW, I never really cared for those Dubro skis myself, and would prefer to build them also. I'm sure you could warp and maybe glass over a bit of light ply, or something of that nature.

Thought about it and then decided I didn't have enough patience, after all it's 28C (82F) here today and by the time the temp drops down to freezing the grass will be too long!

I did a lot of flying last winter since I had just re-discovered the hobby the autumn before. Actually when there's no wind, it's not that cold. You just need to bring a good down jacket and a thermos with a good cup of tea.

Over here the white stuff started to fall in night. I was thinking about skis for my Fokker D.VII already. I think to recall that there actually were some of them really equipped with skis.

Right on Gupi, it's quite mild if there's no wind. Kiwi, I'm 60% sure I envy you. I can't decide if i'd prefer snow or 28 degrees C, but I'm leaning toward the warm weather !

I'll pop to the model shop today and pick up some ply. The shop in Abergavenny has just changed owners, really nice chap bought it from the couple who ran it for more than 20 years (of which I've been alive for 24, and modelling for about 23 and a half !) So there's always interesting new stock in at the moment. I saw this is there yesterday and had to nail my wallet to the floor to stop me buying it:



Anyway, I'll get on the skis later today.

Will.

I do a lot of ski flying. We've got about 11/2 feet of snow so far. Yep, if there's no wind it's not too cold at all. It's a blast flying off the snow.

I bet it is, and I think we're in for quite a bit of snow this year.

I just wish people would stop trying to dirve tiny city cars on the snowy icy roads here. They slip all over the place and look very dangerous...one nearly hit me yeaterday.

Not very scale, but here's some photos of my Astro Hog on skis. These were taken in 1989 or 90, I can't remember now, near Greenwood, Nova Scotia. Obviously thing work best when the snow is firm and packed. If it is fresh and fluffy, the model will sink. Although I must say that I remember on one particular day, the snow was soft and fluffy and I got airborne and then started shooting touch and goes on the soft snow. The forward momentum of the airplane with some speed made sure that the airplane didn't sink into the snow, and it left the most beautiful twin rooster tails that you could ever wish for. That was pretty cool. The worst part of winter flying was cold fingers and getting the motor started. A squirt of lighter fluid or WD-40 certainly helps there. The skis were just 1/16" ply, I think. Looking at the photos I think they were a bit on the small side.

Incidentally, that same OS FS-90 4 stroke motor is still powering an Astro Hog of mine. The airframe in the photo is deceased and I built another in 2002. It's my last glow plane. I bought the motor in 1982 and it is still running strong! Heck, I'm still flying the Hog with Kraft servos! (Surely someone remembers Kraft?!)

Great photos! Looks like you had fun with it . I think I'll make my skis about4" line by 1" wide. That should do for the 1m span minimag even on quite soft snow.

When I used to fly in the cold a lot I made a fleece cover that the transmitter and my hands fit into. Kept them quite warm. On a really cold day I pinned a couple of heat packs inside the cover.
