Thunder Tiger Pro 46 - Dead stick
TT engines do take quite a while to fully break-in.
I've had the same happen to me. Usually it was because it was too lean or the low end wasn't set right.
They seem to like being run on the rich side as they tend to really unload in the air.
Run'em slightly rich+ for tons of power in the air.
Good Luck,
Jeff
