I'm an engineering student currently working on a solar powered r/c
boat project. I'm looking at ways to power the boat but I am having some
problems i hope you guys can help with.
How would you seal the hole created for a prop shaft to stop water from

I have developed a system that can drive a model car or boat using GPS
guidance.  So far I have tested it on a model car and was wondering how

people use ocean kayaks. Can't handle that.  Are there radios out there
that would give me an effective operating range of 300+ yards? ...

Hi, I am planning to build a large Deep Vee boat (approx 50 in.) and I
want to install a gasoline motor, probably a weed eater motor in it. It
happens that these motors stall at times. I want to be able to bring the
boat back to shore easily. I have seen that some boats are using

One of the employees at my LHS (their RC guru) said that Spektrum brand 2.4
gh radios shouldn't be used for boats.  He went on to say that the signal
isn't reliable because it "reflects" off the water, adding that Futaba
radios don't have this problem because of their frequency ...

Any interest in steam boats from this group?
I am currently building a Krick Victoria with a Cheddar Puffin steam
engine. Information on doing this seems rare so I am charting my
progress on the web with photographs and links to help others that

i am now building my new RC boat Hull (boat design taken from this
forum)... please help me what are the basic components needed to build a
complete RC boat ( thinking of brushless motor to intall on it). Thanks
