Got this toy grade RC Jet boat, made by a company called NQD, turns out they work really well when upgraded to hobby spec electronics.
It only cost about $50 Australian dollars shipped to my door. The new brushless motor, ESC and 2.4ghz RX cost another $50 and a little time fitting them up. It now runs a small 1/16th scale motor with a water cooling jacket and a water cooled ESC. The RX is a Flysky 2.4ghz job. Battery is a Turnigy Nano tech 2S 2200mah.
speed is ok, it has enough push from the jet to hold it’s own and pull out of a decent current, so I will be looking for rapids to play in.
I repainted it from white, first using undercoat and then a base coat of Tamiya TS-52 Candy lime green.
Then I laid a stencil of a dragon that I hand cut after printing an image from the net.
and shot very lightly around it in black with my airbrush.
Then I tried to make a real fire effect using white, yellow and red in the airbrush, it’s only my second attempt at real fire.
Here is a little video I shot of my first two packs using it.
RC universe has a great thread with information that helped me a lot with my decision to buy the boat and what to do with it after I got it.
I bought a pair of 3S batteries for this car to bring the power up to 22.2 volts on 6S.
With the stock gear ratio it goes about the right speed for this track, but this car has a major problem. Tires.
There are not many tires available for these cars unless you want to pay almost half the cost of the rolling chassis for a set of Sweeps or Inpanema (spell) tires.
I blew out one of the stock tires after the second run. So now I have a set of tires on there which only cost $20 shipped. They are only cheap Chinese junk, but haven’t worn much after the first run in this video. I helped them out strength wise a little by putting Gaff tape on the inside. However, they appear to have very weak sidewalls as there are already splits in them.
These are the tires.
Took a bunch of cars to my local track and drove around for about 3 hours.
took the DM-1 Spec E now with 6S and 17T pinion. It took off on the straight, literally. So I dropped it back to the 13T for this track and it works well. Tyres are a problem. The other problem was that I was so excited to drive it I forgot to video it… DUH.
Though, here is a video collection of the other cars I drove.
It’s just driving with no music, add your own.
