Hi Turbine Guy
The thrust level for the TJT-3000 is misquoted on our website and is scheduled to be fixed in the next edit. Its just a bug that slipped through he cracks... The ~34lb spec is the military specification, not for sale to the R/C community.
The correct specs are listed below.
Thanks,
Kelly
