I have a couple of the red 66 Mustangs (I have a real life one too), and the information about these MM-RC's is almost non-existant. I want to bring up a couple of things that I have noticed and maybe we can get some good discussion going on them.
I have seen the battery mod for the Bits and it says that you can replace the normal battery with a 13AAA NiMH battery. These MM-RC's already come with a 15AAA 120mAH NiMH battery. There is also enough room to put another battery right next to it (dremel the plastic out next to the steering motor and glue the steering motor in... viola! The perfect spot for a 2nd battery). It would also seem that the 45 second charge time doesnt do this battery justice. From what I have read, you need at least 5 consecutive charges to get a full charge on that type of battery. Interesting.
Next is the antenna. It is a fully telescopic antenna and is capable of up to ~20' in range. It seems like this is a better idea than the single wire that comes with some other cars. I bring this up because there is a mod to make your controller have a telescoping antenna for other mini-RC's. Nice to have it there already.
Tires is the last thing I want to mention right now. The tires are a little hard on these compared to normal MM's, but they seem to be a little more durable. I dont know how to make them more sticky, but it seems like they are stickier than some others. Could be my imagination though
In summary, you get a car that can drive for 20-30 minutes, has a great range, is fast (even faster if you get a 2nd battery for it), and has good, responsive steering ... all for under $15 bucks. The only downside I see is the pull it has when going straight. I dont know how to fix that other than the switch on the bottom. Sometimes you get a good one, and sometimes you get one that pulls to one side or the other pretty serious.... it varies car to car.
I want people to at least check them out (Walmart doesnt as questions if you want to return them). Hopefully more people will get into them and get into more serious modding with them
