Tachikaze,

I hear you on the gear reduction issue. I do not plan on using any gear reduction. According to the Dauntless plans that I am reading under power notes. It states that the real Dauntless was capable of speeds up to 50 mph! S for me scale speed is a high power motor. I will need a strong motor that will push 12,000 RPM Here is the motor link:

Thoughts? I plan on fiberglassing the hull this weekend.
