Just a few weeks back, I decided to order a Monster Beetle – 1/16 Brushless 4WD from HobbyKing coz it was relatively cheap and also coz it came with a 25Amp ESC (Electronic Speed Controller) with breaking and reversing function as well as a brushless motor. Since I already had an old and unused Futaba gun controller, I decided that for USD69.50, it would have been one of my cheaper RC purchases in a while. Heck it was even cheaper than the cost of 1 of my battery packs for my Trex 550E Chopper!
The kit arrived promptly after about 9 days or so in good condition. They basically turned over the box (inside out) and packed it with proper cushioning. Customs did not halt the package so I was really glad. Over the next day or so I fixed up the car by putting in my Receiver and Controller and immediately ran into my first problem… the ESC wouldn’t arm and the Steering was locked to one side whenever I plugged in the LiPo battery. The problem was however soon rectified as I found the problem to be with the transmitter. I had to reverse the servos (or reverse it back) and also perhaps switch the channels (from 1 to 2). I guess it’s been a while since I touched that radio. In anycase after doing all that, the ESC armed perfectly and full speed, breaking as well as reverse was achieved. Even the steering responded well and properly.
To fit in the Lipos which I had, I had to remove one side of the battery guide. That was easily done by removing the screws for the holder from the bottom of the car. After that, the packs went in easily and fit nice and snug.
When using the car with my old (>3-4 yrs old!) 3S 1500mah Flightpower pack, the ESC didn’t seem to hold up even though it was rated for 2-3S lipos which fit in perfectly. The ESC went into overheat protection only after 2-3 of running. However when running with the 2S Zippy Flightmax 2S1P 20C, the car ran fine without any problems. This pack was purchased from HobbyKing at ???http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=6541&aff-56685
The performance of this car is amazing. Though it is only 1/16 scale, it is pretty zippy for its size. Stock on 2S, it runs approx 40km/h. On 3S, it runs perhaps 60km/h? Whatever it is, its pretty zippy for such a small thing. You can use the car indoors as well as outdoors and with its adjustable camber, shocks, ride height, you can fine tune the car to your liking. I kept my ride height on the high side and shocks hard so a few tumbles happened during tight high speed turns. No damage though and the car body held up very well!
For those of you who has a spare controller and receiver, this is a recommended buy. At only USD69.50 (shipping not included), you get a lot of car for your money (ESC, Brushless Motor & etc).
