I put a blade in mine and launch it DLG style as well. I think it allows me to throw it harder, and I throw pretty hard. (I don't do the full rotation, just wind it up behind me and fling it while taking a step.) I have hundreds of throws on mine with no problems.

The tearing on the wing probably comes from twisting the plane somewhere in the launch motion. The throwing peg, (or blade), allows the plane to find its own orientation to the air for less resistance and higher launches.

I agree with Edwinza though, the Alula is really better suited to light wind sloping than thermalling.

This picture might help


I cut the a slot and forced the blade through so that it was where I wanted it.

Then cut a shallow slot around the outside of the blade and stuffed a piece of carbon tow into it. I did this on both the top and on the bottom.

I wicked thin CA into the slot and around the blade on both top and bottom.

I also used some clear lightweight packing tape on top and bottom of the plane, just to keep it nice looking where your hand would rub off the paint.

The ruler is just there to give you some idea of how long the slots are.

The reason the slots look like they do is that on the bottom of the plane the slot runs up next to the Carbon spar, so that the carbon tow ends up attached to the spar and should transfer some of the throwing stress to it. I cut the slot at the rear edge long enough to extend past the elevon cut so that the foam wouldn't try to tear the wingtip off starting at that cut.

Yes, Carbon tow is like a carbon string that has not been braided. I did a search in the RC Groups classified forums and found a guy that was selling it right before Christmas, so he probably still has some:
http://www.rcgroups.com/forums/showt...ght=carbon+tow

You can buy the carbon blade material at this site for $5 US plus shipping:
http://www.rcbuilder.com/Merchant2/m...tegory_Code=AP

or he has a finished blade for $15 US plus shipping:
http://www.rcbuilder.com/Merchant2/m...tegory_Code=AP

The gentleman that runs this website is ASK here on RC Groups. He is very knowledgeable and easy to work with.

These are all located in the United States, but these items are very light and often shipped in an envelope, so shipping couldn't be too much. (I think the Christmas cards I sent to Eastern Europe were about $1 US each for postage.) I am certain there are suppliers that carry these materials in Europe, but I don't know who or where.

In my post #873 above where I cut the slot for the Carbon Tow I forgot to mention that on the bottom I run the tow up to the Carbon spar and along side of it for a few centimeters so that some of the throwing stress is transferred to the spar. I will edit that post to mention this.

15mph winds and 0 degree temperature must give a wind chill about -25 or something like that.

You must have really wanted to test fly it.

With a little less wind and a lot warmer temperature it will be a lot more fun to fly, but maybe I'm just soft.
