I recently got "back into" Remote Control Car Toys.
Advances in tech trickling down from the wealthier RC Plane/Helicopter market means better radios, batteries and motors.
15 years ago there was no* lithium-ion polymer, 2.4ghz radio and brushless motors.
Now all that stuff is available to
consumers direct from China, and as is typical cheaper than predecessor technology.
*as in not mass produced specifically for radio control toys.
Here are some pictures of them.
This is a 1/16 scale. It is a "Mini E-Revo". Made by Traxxas.
This is a 1/10 scale. It is a Wraith. Made by Axial. It's a quasi "Rock Crawler". Meaning it is designed to go slow and "crawls" over stuff.
It came as a kit, it goes from this...
to this.
Front.
Back.
The Wraith is a "scale" RC, in that it comes with stuff that makes it look like a "real" vehicle. Such as an interior with seats, dashboard gear shifter ect. I didn't put it in because, I'm a bit of a hack when it comes to "art" kinda stuff. I've got the patience for it, but no matter the effort...
And here is a "Touring Car". This one is pretty fast. I don't have a GPS to put in it, but I would guess at around 55-65mph. That speed makes Big Box Store parking lots seem small.
The motor is a 3.5 turn. Maybe better said as it (apparently) can draw 93 amps at 7.4volts, That's 705 watts! Seems unlikely to me as that is just under one horsepower. Maybe half those watts turns into heat
Oh and it's a 1/10 scale. Called "TC6". Made by Team Associated.
I am somewhat interested in planes, specifically electric jets. the "turbine" of the jet is called an EDF, Electric Duct Fan. In addition, there is FPV (First Person View). Video goggle + a wireless camera means a great view flying the plane. The technology for that seems to still be out of reach for my wallet, and the image quality is still improving. But I am sure it will come down at some point, maybe once the quality "plateaus", probably dependent on wireless tech.
I think there is some debate on whether a brushless motor is an AC or DC motor. I wonder if PF could sort that one out?
