Snow Ski's on a tail dragger...


Hi all,

Got the urge real bad to fly and since we have a bunch of snow on the ground up here, I whipped up a set of skis for my Mini Telemaster last night. Question is: Should I also put a tail ski on or will the wheel be okay. My first inclination is to build another ski, but I'm itchin to fly NOW!!!

Thanks

No tail ski on my Toledo; but do one on my 1/4 Cub.

Size of ski (front) and need for tail is mostly a function of snow condition.

You definitely need something for the tail unless you have ice hard snow. I have made simple tail skis out of soda bottles, using the shoulder of the bottle. Packing tape it to the fuse in front of the wheel and also over the wheel or wire.

Have fun! -Steve

The planes I fly on snow are mostly light and small (the largest is 48" wingspan) but none of them have skis on the tail.

Don't bother with tail ski. It'll sink in the snow and act like a rudder.

Thanks for the replies, everyone. I wound up making a ski for the tail. I added a little skeg for directional control.

I flew four packs out and learned a couple things.
#1 my 4 year old packs aren't very good anymore and,
#2 I hate flying in the cold!!!

Anyway, here's some pics:

Wow, those are some nice looking skis! I especially like the tail ski-- I was surprised that others recommended against it--in our powder in Idaho they really help keep the tailfeathers from augering in.

Sounds like you had a chilly day. You can use all kinds of clever transmitter, but I just dress extra warm and try to only go out if it's above 20.

Your old packs probably weren't helped by the cold. Keep them warm if you can before use.

Take some pics next time you are out!

I fly aerobatic, 3D, and sport planes in the snow, and none of them have tail wheel skiis. The tail comes out of the snow in about one foot, so it's no big deal. Even in deep soft powder the tail only sinks down to the bottom of the fuse. Just don't give big elevator inputs when the tail is down in the snow or you may catch a counter balance.

These Tx gloves are great for winter, especially when fitted with an additional heater that runs off a small lipo

I have a set of skiis I built from ol RCM plans years ago. I only put skiis on the main gear, it doesn't need a tail ski at all. It's a .40 size hots, and when I fly in the snow, I'll burn a gallon of fuel in a day. I absolutely love flying off the snow, everywhere is a runway. The tail comes up quickly on any taildragger I've flown and so it's not worth bothering with a tail ski.

I copied the tail wing the the DC3 used on their skis. The TV series "Ice Pilots" showed it. Does away with the strings and rubbers. Words vey well keeping the skis following the airflow.

All but a flight test remains.

Simple and nice & light.

From foam tray, wire gear struts, with fuel tube springs and Epoxy.
