Here is something I was working on, tried flying it without a tail, which it will not do. Too much vertical area ahead of cg I guess. Have since added a fin but not flown it. Will do so when weather gets better.

I was using old rubbers and did a loop during which the wing separated from the fuselage just enough to jam up the aileron servo and plow into the dirt (snow).
Had to replace cowel with makeshift plastic Sprite bottle. Also my little ski toes fell off. This plane is getting uglier by the flight but is still a hoot and flies well no matter what I seem to do to it.

Have been out in the snow flying my wing. It's finless and waggles abit but I think it is kind of funny and very controllable so don't mind at all. Never have to worry about knocking the fins off. This plane is pretty indestructable which is good because I tend to get disoriented near the ground a lot.

This is a strange beast. Haven't got the bugs worked out yet but still ran two batteries through it and had fun trying to control it.
I think it needs a bigger tail. I did move the battery to the rear and angled the motor up a little more and that seems to have helped a little but it still just wants to mostly run around in circles. In powder snow it tracks straighter but any little ice bumps will throw it onto a new track, no real pristine snow available here.


Online video of it running around on ice here: http://ipikz.com/Snow-Skitter_v1333

Update 02/2013 I made a much larger tail and rudder and tested it outside my house - much more control. Will go to icy parking lot tomorrow and test it out.

Tried it, better control but still goes in circles. Too much nose weight I think.

Did some takeoff and landings today with my homemade skis. They don't look like much but they are functional. Put bungy in front and wire in back. Before I just had a wire in front but the plane would do a nose over on landing.

I just give it full up elevator and full throttle and away it goes.

It is -17C, but great fun.

I hardmounted the skis to the plane and now just put the battery in under the wing. Much easier than having to remove landing gear to put in battery.

Link to video. Can't get to youtube anymore so loaded it to here:

Ok, the green things came off in a hard landing but the skis still work. Wish I could form a little bend in the acrylic ruler but spring will be here soon.
