The TK10 on normal mode shouldn't burnt like that, the heatsinking is more than enuf to dissipate the heat, you might only feel warm, even running down for an hour. What I believe is that your battery powered is over the specifications of 6v++.
A single 17670 battery would be better for the TK10 in the future, when you get it fixed

EDIT: But 17670 won't be regulated very well.. hrmm.. 2x LifePO4 next time?

Noted with Thanks, will get these RCR-123 tested out.
If I'm not mistaken previously read in CPF, TK10 OK with RCRs , built like a tank-mah
Once I've removed the TK10's head, can I just "cut" or polish away the emitter's burnt resin?.
(Just like susuman's P3D Post #32525838·) or better to get a new Q5 from Dealextreme?
Is it difficult to remove and solder a new Q5 emitter to TK10 ? Newbie....
What about the emitter size? ( 16mm Base Dealextreme sku.11022 or 14mm sku.11023 ) ?
