Trata II - The destruction! (Thanks Jip!)

Moves faster than Trata, on snow and ice

Update: Thank you for asking me to make a jump with this, jip. Now both Trata and my camera are broke. (Last video) - But hey - Snow is melting, who needs Trata any more? Time to rebuild!

PS: Jumps with things that are driven on a high placed force makes ugly jumps!

I just wanted to play some with the original Trata, that I made the other day in 2 hours. I picked up some materials, and oops, I made a Trata II instead :)

 

I tested it in the evening, on hard snow, and it was very fast and fun! In winter time we don't get a lot of day/sunshine-time, so it is always a quest to find time to shoot video when it's not too dark (like on Trata I)

Next day / today, I was going to shoot a good video.. but we got like 30 CM of loose powder snow! And it is not made for that, it just falls through and get burried.

So there is only a pre-video for now, I have to wait for the weather to change, or the snow to settle a little..

 

Theory is this:

Below is shown where the point of gravity is. It is supposed to be way back. I want it to allmost stall / have the front very light, so it can take the roughher snow, and lift itself up.

If this should be too much, I have placed some sticks at the back to prevent it to flip completely over, and let the propeller hit the snow.

(Yes, the propeller is broka enyway on the pictures :) It was a late night test run, and happened because the servo fell off. Not enough hot glue! (And too few wirestrips)

Now, IF it should not lift itself over some pile of snow, I do not want elsectronics to dive in, so this upside-down deck was placed in the middle, as a "sledge".
