After much practice, I feel more comfortable crimping JST connectors.  The right tools (Iwiss) and some Youtube videos also helped.
Now, I have one Deans (F) to Tamiya (M) wire adapter but I would like to make more.  I have the parts but don't or can't find the proper crimper.  Can anyone please lead me in the right direction?  As always, much appreciation and thanks. 

For Tamiya you need to get an open barrel crimper.

I purchased this one.

Or just order a couple adaptors from Amazon/ebay.

Thanks Jarlath.  Yes I saw those but long ago I bought the individual Deans with bare soldered end and set of Tamiya male and female connectors. So I guess I'll be buying the suggested crimper.  Why do I always seem to take the hard way to do things.  I guess as a rookie this is how I learn.  Thanks for your advice.

So these will crimp Tamiya plugs ? I guess two crimps right ? One for the wire with casing and one for the bare wire ?

Have one sitting sitting around and didn't realized it will work.

yea.  I guess it's a 2 step operation unlike the ratchet type for the JST which does it in 1 operation (Iwiss SN-01BM Crimping Tool)

Ya. It all a matter of how fast you want to do it. I've also found that the open barrel connectors have varying degrees of quality as well.
I have 3 sets of crimpers for smaller ga wiring (22-28 AWG) JST/Futaba/etc.. and each crimps certain connectors better than others.

Cool will try that out. Tamiya style would be for power only so it won't be 22-28 AWG for me. I used the ratchet one for the JSTs.

All I use is 16 or 18 AWG on the tanks for power.

16AWG = 22A continuous
18AWG = 18A continuous

Motors typically only use 3-4A each at upper loads, but can draw >15A each if stalled (jammed tracks).

On RC cars I use 12 to 14 AWG for power (Some are 10 AWG)

Thanks Mike. I didn't need to know that.
