such like GP1100 or Intellect 1200 Battery .......

they have stick pack battery and also have side by side battery for sell,that's no need to solder by yourself...
But you also can buy the battery and soldering by yourself like 1/10 that kind...

MRS4 stock can used AA or AAA battery

Four AA or AAA battery....
MRS4 is come out by HPI (Micro RS4)

I think it's very hard to get new one....but maybe you can get 2nd hand....or you can check on www.rcmart.com to see either got sell or not...

nope....still have a lot people play it...just the plastic part maybe very hard to get it in HK....GPM at HK still can get the upgrade part...
