Tranquility or adrenalin
Wellcome to RC boating, dwell here and you are sure to find something that enchants you. In RC boating there is a strong culture of assembling and customizing your own boat, finding the right set up and trickest parts is a sport within the sport. Do not worry about beeing bored, the boats run 50, 60, 70 mph or more, accellerates like firework and regulary make six feet leaps with screaming engines. Do not worry about getting them wet, you are running again five minuts later. Do not worry about loosing them, modern radios do not fail, forget to charge the batteries and they will shut the boat down safely, run out of range (requires binoculars) and they will shut the bout down safely, mix up the frequency... newest radios do not require you to hustle with frequencies. Run on pump gas, order parts by clicking on internet, build in the hobby room, transport in the trunk, instant support by asking on a online forum. Pick any forum in the links page and start swaping experiences with the polite and helpful people of the boating community. Really, putting one post up is a "must do" before you enter a RC boating project.
RC boating provides the same technical challanges as full scale racing at a fraction of the price and effort. RC boating awards great driving exitement without the danger of onboard rides. With a truly great boat you really feel the speed in your hands and spine. They look like toys in the pictures, but top boats are pure sport.
RC boating is affordable and requires little overhead in terms of trailers, storage and what not needed for full scale racing. You can pay only a little or you can pay substantially, but it will in all cases be affordable. Get running for almost just the change in your pocket or take the opportunity to not have to compromise. RC boating presents the possibility to be second to none. If you desire it, and realise you are not buying toys, it is within your reach to have the best of everything. It is not free but it is affordable.
Take your time, pick and choose, ask on the forums, enjoy composing the ultimate racing gear, be a racing artist.
