This is not a build but a modification of a cheap Chinese boat just for fun, I got a bit bored of scratch building projects as they take so long especially as I am not retired yet.
The NDQ 757 Coastal Brother 1:25 Radio Controlled Racing Power Boat cost about £25 from Amazon.
These boats have a basic 27mhz radio and two 380 type motors which have forward and reverse and you steer by powering one motor or both for straight ahead.
I bought two of these boats as they are light and about 24 in long, one to convert/upgrade radio, esc and brushed motors the second was to upgrade radio, esc for brushless motors.
The brushed motor version I put in two higher rated motors (390) with cooling fans built in, but same motor diameter but longer body I had to modify the mounts, kept same couplings and shaft/propellers. I did remove trim tabs (fixed) and replaced the straight running adjuster for a racing rudder.
The brushless version is the same but has brushless motors 2x 2845 2600KV sensor less
Max Current: 42A
