Nice. I would go for the associated. For electronics I would get a
Hobbywing XR10 justock 13.5 combo. For batteries I would look at Maclan, SMC, and Trinity shorty packs. Some chassis can do low profile packs which are a little less heavier and shorter in height. CHNL is also a battery brand too. For 1/10 racing there are only 2s lipos. There is a normal 7.4v lipo or there is LiHV (Lipo High voltage) which is 7.6v. For servo I use this
Xpert 4000 in my 4wd buggy and works just fine. Plenty of speed and torque. Another option is the
power hd B4. For radio, you would need a 4+ channel receiver. 1 channel for a transponder and 1 other channel for a motor fan. You can technically use a radio you already have from your bashers but I recommend getting a cheap radio to start out with. Radiolink is a good starter radio. I have the RC4GS V3 and its a good radio (besides the plastic) I'm currently using that for my 4wd buggy. I plan to upgrade to a mid range Futaba (4pm).
Any local hobby shops for extra parts? If not I would stock up on parts from online.
