The Rock Crawler Action Monster Truck is a beast on the road, with it's 4 gigantic wheels it can drive over almost any terrain. Primarily for off-road driving this big truck is sure to keep your kids entertained in the outdoors.
Please note : Batteries Not Included. For Ages 6+. 6 x AA batteries for car & 1 x 9v Alkaline battery for controller are excluded.
Thanks, got one!

Bought one of their Ferrari model before made by the same manufacturer.
Build quality's not so bad actually. Happy with it.
looks like a pretty cool rc off roader but 6 x AA and a 9v its gonna chew through more than its price in batteries.
hence the rechargeables
rechargeables are still far inferior to just a built-in li-ion battery pack or a removable li-ion pack. Plus rechargeables are going to supply a lower voltage so you're not going to be getting the maximum power it is capable of.
Alkaline batteries drop below the voltage output of NiMh cell pritty early in the discharge cycle, and stuff like Eneloop pro has lower internal resistance.
I generally get more performance out of stuff with Eneloop pro's rather than Alkaline.
@scott: Rechargeables start off at 1.2v whereas non-rechargeables start off at 1.5v+. Some electronics won't even work with 1.2v batteries. 1.2v * 6 vs 1.5v * 6 is a difference of 1.8v which is quite a big percentage. Regardless, a rechargeable li-ion battery pack will definitely be superior as you aren't needing individual batteries which was the original point I was making.
@Bill: You are correct that Alkaline batteries start off at a higher voltage, but as per my comment they will drop below the voltage of NiMh battery fairly soon in the discharge cycle (around 40%). After that point the NiMh has higher output voltage.
And that is before considering the reduced voltage drop from Modern low internal resistance NiMh batteries (such as eneloop).
Anything that isn't going work on NiMh batteries, would require alkaline batteries thrown away before they are half discharged… Haven't come across such a device in the last few years.
Agree that bundled li-ion pack would be ideal, but likely incomparable with the price point of this toy. Nice thing about standard AA's is that they can be moved around between various toys.
@scott: Hey there scott,
I understand what you mean. Essentially I guess the reason something wouldn't work with NiMh batteries is because the voltage cutoff would be higher than the initial voltage they provide. With something like this cheap rc car, there probably won't be a cut off but rather just a degradation in performance, correspondent with the supplied voltage. My understanding is that this means the alkaline is going to allow the RC car to use the starting high-end voltage which would provide the maximum power I was referring to earlier, then the voltage would drop and the batteries would be effectively "dead". The NiMh on the other hand would supply a constant mid-end voltage that results in continuous sup par performance for the life of the battery. what you mean by devices that require alkaline batteries to be thrown away before they are fully discharged would be that they require a high cutoff voltage and are unable to use the low-end spectrum voltage. This seems to correlate correctly with everything I have said.
@Bill: My experience is that moving from alkaline batteries to Eneloop Pro's in medium draw, voltage sensitive applications dramatically improved my usage experience.
Alkaline batteries go well when they are fresh, but the experience quickly (like 5-10 minutes later) become's substandard).
Have a bubble machine for my child (basically 6 AA's running a fan). With alkaline batteries the machine would run well for 5 - 10 minutes, and after that the fan would be pretty weak to make the bubbles. With the Eneloop pro's the machine will run well for over an hour (actually have never run them out).
I had got fed up with old NiMH batteries in my youth, so just used disposables for decades. When I got a nice camera, the external flash ran AA's and reviews said Eneloop pro's were the way to go. Tried them in other stuff and are now a real fan. (That said they are very expensive.)
erm, we are talking about a 38$ RC Car for kids,soo not gonn be fuzzy with the limitations of this toy tbh.
You will get around 15mins of run time according to similar products.
Takes me back to the days of waiting 3 hours for quarter of an hour of play.
hmm do I need one tho
Same man… I tell you what if you get one I’ll get one ahaha
so did you guys got one? haha
got mine and so happy with it..long range and definitely can run through the stoney road..
damn… regrets
Usually $59.90 if anyone is wondering.
