Wait a second... you were using an outrunner on that?! What was the RPM on that setup? How many cells? I've seen one micro speed demon running off a CD-rom motor... they're so cheap compared to the regular sized hydros too! Whoa! I've got a Hacker B20S with a 4:1 gearbox... is there a water prop I could use on that little beast? I checked the Kv and it's at about 4091 without the gearbox, so I'd be at around 1023 kv with the prop. Any recommendations? BTW, I've got a Mega 16/7/7 that is being taken off a model... kv is 2450. Might carry a LOT more punch than the one you recommend. Any ideas? I can take the hacker out of the plane I don't fly anymore, as well as the Mega which I don't fly either, and put the hacker in the new model...

Uh, btw, I'm new to boats. Would I be a fool to get one of these? I'm experienced in model aircraft, I'm saftey conscious... and I've got a local lake. Actually, I've got too many lakes to my disposal. Operating a generic R/C boat isn't an issue.... no other R/C boats around my area, ever.... Well? I mean, I can underprop it, right?
