OK so if I go all manual and type
https://zoink.it/torrent/<hash from torrent site>.torrent
I get a torrent file back that I can save and run with QTrapids.
I have been looking and there must be a way to query with a magnet link to get back a .torrent file, I dont have they perl or python fu to do it though.
The links I posted earlier though don't do anything...

(edit)
And on try two less than a minute into the renewed download QTrapids again crashes the phone and corrupts MyDocs.
dosfsck -a /dev/mmcblk0p1
too bad QTrapids connects and joins the swarm much better than Transmission.

(edit)
attempt 3
Even dropping the download speed to 200 ends with crash and corruption on QTrapids.
