RE: Thinking of leaving cars for boats
Boats are great. I have just finished building mine, it's renovated wooden boat converted to .12 nitro. I have found that the engine only ever plays up on the shore when starting, adjusting etc. Once the boat is out in the water, fuel permitting, there have been no problems. Although my boat looks more like a fishing boat, it's very competant and I have to be careful at WOT as it is now capable (since I've got the mixture settings right) of around 20 knots - not bad for a complete home-built.
I'm currently working on an electric rescue boat . . . yes, a rc boat specifically for dragging in dead rc boats. I'm fed up of wading around in the local river (it's a very slow, small river,not dangerous like some, I use my boat at a large, deep lagoon like place - it's all I have that's local) so I'm building a boat to sort that problem.
Anyhow, I have a car and a boat now and I can say that boating is great fun, possibly even better than cars!
