News flash Turnigy Stadium King 2wd truggy / ZD Racing ZMT-10 Brushed motor model is 3s capable

Well I decided just for giggles to see is a 3s lipo would burn up the esc for my ZMT-10 and was surprised to find out that the esc recognized that the pack was a 3s . Normally the esc ( currently in a Clodbuster ) Goes through its little beep sequence and I give it little thought but when I hooked up a 3s lipo to the esc I knew something was different instead of the normal BEEP-BEEPBEEP-BEEP IT WENT BEEP-BEEPBEEPBEEP-BEEP signalling that the voltage cut off recognized that the pack was a 3 cell I couldn't believe it . after driving for a bit the esc showed no heat increase so I feel safe in saying this esc is good to go on 3s lipos but I still recommend a lipo alarm as the voltage cut off is too low for my taste.

Hobby King Programming Card for Car ESC (USA Warehouse)

Well it does exactly what it is supposed to do its only downfall is that its construction is primarily a circuit board and card board and it doesn't seem like it would put up with much abuse so I recommend keeping it in a  safe place. I do wish there was a cheat sheet for the buttons as there layout makes it a little hard to remember what the far left and center arrow functions are unless you use it constantly.

According to my research this programing card works with these esc's

YKS 5000mah 20c lipo batteries my opinion

Well I bought a 5000Mah 20c 2s 7.4 v lipo battery pack from a company in Brooklyn New York .

06/10/13 - 09/01/14 RIP

Minimum Capacity:	5000mAh
Configuration:	2S1P / 7.4v / 2Cell
Constant Discharge:	20C
Peak Discharge (10sec):	30C
Pack Weight:	308g
Pack Size:	145mm x 52mm x 30mm
Balance Plug:	JST-XH
Discharge Plug:	NO
Quantity:	1

I had  good experiences with their smaller batteries as can be found in other parts of this blog but I find myself not being able to recommend this pack and many of their other higher capacity packs .

 This particular pack was the best deal as far as I could see but after getting it  I realized it wouldn't fit anything I owned its several mm wider than a shotgun style NIMH pack  and longer than a 6-cell pack but slightly shorter than a 7-cell pack . This made fitment virtually impossible in almost all my models but my ZD Racing 1/10th scale truck and really it was such a tight fit that It makes me uncomfortable . 

The other problem I had was that the power output in my opinion is low even for a 20c rating I found I could only get reasonable performance for around half the pack after the voltage dropped below 4.0 volts it could not provide the amperage needed for my mild brushless system that I was testing it with . The measured usable  capacity was normally around 3000 Mah .

This pack has a Relative Amp 20C x 5A = 100rA 

$12.99 / 100rA = 0.1299cE the lower the number the Cost Effective

Now looking at this graph it should give you a idea of why my battery didn't meet what most people would expect from the ratings  . To clarify if you don't see what this is showing is that the mah rating was determined at a 1C discharge or a 2.2 amp draw but when a 25C load  was introduced the usable capacity dropped off from 2250 ish to 2050 ish .

Its also Important to note that when a manufacturer uses this method that the gap between the  listed capacity and usable capacity gets bigger as the capacity get bigger . This is one of many reasons why most sellers and battery makers don't use the 1C discharge method to determine battery capacity.

The reason I find it hard to recommend (or even buy ) there other higher capacity and C rated batteries is that for the cost you could be buying a battery that is well known in the hobby community for good performance and value with a more appropriate battery rating  .

Turnigy Pure-Silicone Wire 10AWG (1mtr) RED and BLACK ( USA WAREHOUSE)

Well seems like I always need wire for something so I bought some from Hobby king and all I can say is wow this is some excellent wire for the price the silicone is some of the best I have ever bought and the wire its self  has a nice balance of flexibility from being a fine strand wire but the strands are big enough that strength should not be compromised .
I ended up purchasing 10 gauge wire mostly because it was in stock at the US warehouse and I hope they add more sizes as time goes on because well 10 gauge wire is a bit overkill in most situations.

So if you need some quality wire for cheap , look and see if they have the size you need .
