Default 1/18ish Toy Short Course truck hobby conversion

I picked up this little SC truck at Marshalls for $15 a few months ago with the intention of sticking some hobby bits into it. I brought it home and was impressed with the details: Lexan body, Hex mounted wheels, soft rubber, front/rear suspension (very stiff), Differential (very surprised to see this!). I had some leftover parts from other projects including a micro radio shack servo I bought on clearance for $5. As with all toy conversions, the steering was the hardest part. I ended up cutting out a plastic plate for the servo to mount to and picked up some ball cup joints from the LHS. The stock car uses 4 aaa batteries and that wouldn't do I had a few of those lithium ion batteries 18650 and wired them in series to a tamiya plug. The result is a fun but pretty slow, cool looking truck that handles really well.

Looks good. you might be able to use a rechargeable 9.6v pack with that esc. might be a bit of a challenge fitting it in there but should work.
steering set up looks great man.

I actually did fit a 9.6 pack in there but it was really heavy. I think a faster motor would be a better way to speed it up.

it might have a 380 motor in it. open it up and check the motor size. a better motor should get it going good.

Its got a fc-280 which looks lime a 130 but bigger. It sems to be the size that most slot cars use so I can probably find a pretty hot one. Pinions are proving to be a pain cause it seems to be about a .5 modular pitch.

Yeah and i can remove it but those cheap brass pinions are so soft the slightest pressure deforms them.

Yeah i know what you mean. i just rip the motor apart so it's just the shaft and the pinion. put it in the bench vise and then a small punch to knock the shaft out.

On Aliexpress you can buy much smaller brushed ESC 20A, hook up a 3.7 500mah lipo. Drill holes in the chassis, and jst connectors black type for leds, lighter and cleaner install.
