NQD 757 High Wind RC Boat: Specs, Upgrades and Tips
The NQD 757 High Wind (sometimes sold as a “Mosquito Craft” racer) is a budget twin-motor RC speedboat about 30 inches (roughly 75 cm) long. It uses two 380-size brushed motors driving twin plastic propellers, runs on a 7.2–7.4 V battery (versions shipped with NiMH or lithium packs of around 1500–1800 mAh), and owners report speeds in the range of about 25–30 mph. Charging takes several hours on the stock charger and runs last roughly 10–20 minutes. It became a popular, modifiable entry boat.

A familiar design
The NQD 757’s twin-380 layout is similar to other budget racers of its era, such as the Harbor Freight Neptune; see Harbor Freight RC boat. These boats offered a lot of size and speed for the money and became popular platforms for tinkering.
Popular upgrades
- Batteries: higher-capacity packs for longer runs (within the electronics’ voltage limits).
- Props: metal or better-balanced props for speed and efficiency.
- Motors: fresh 380s, or brushless conversions with a new ESC and cooling.
- Sealing: better hatch sealing and grease on shafts.
- Radio: 2.4 GHz conversion for older versions.
A brushless conversion needs a marine ESC, water cooling and careful prop choice; it often costs as much as a modern budget brushless boat. Modern options are in cheap and fast RC boats.
Care
- Dry the hull after every run; leave the hatch open.
- Grease shaft tubes to keep water out and reduce friction.
- Check props for chips and replace in pairs.
- Clean motor contacts if performance drops.
- Store batteries correctly for their type.
Buying used
- Both motors spin and the rudder moves both ways.
- No cracks in the hull.
- Battery and charger condition; old packs may need replacing.
- Frequency of the radio and whether it matches.
- Signs of water damage inside.
Running tips
Run on calm water close to shore, stop when the boat slows to avoid draining packs completely, and let motors cool between runs. Twin-motor boats turn well, but a failing motor makes the boat pull to one side, which is a useful warning sign.
Why twin motors
Two motors driving two props give more thrust than one small motor and help the boat track straight. Many twin-motor budget boats also use the two motors for steering assistance. The downside is that both motors must stay healthy: if one weakens, the boat pulls to one side. Replacing both motors together keeps them matched. Twin props should be counter-rotating to cancel torque; check they’re on the correct sides after maintenance.
Where to run it
A 75 cm boat handles small ripples on ponds and lakes better than smaller toy boats, but it’s still light. Run on calm days, stay within range, and keep away from swimmers, wildlife and other boats.
As with any older boat, replacing the battery with a fresh pack of the same voltage usually brings back most of its original speed and run time.
Keep receipts and manuals together in your boat box.
