I have a Spitfire (boo the P51 muscle machine, I like the finesse of the British aircraft). It's 1/5th scale, quite a large aircraft and should be moved around by two people. Takes a 62cc 2-stroke to turn over the prop. That's my biggest, but I think my most impressive is the 1/6th scale Bell Jet Ranger that I'm in the process of rebuilding.
All of those are on the backburner as I've discovered a love for yachts anyway, and have a 2.25metre hull that I'm restoring and re-decking to add a 3.5metre mast, should be capable of 30-35 knots on water when she's done.
I keep my flying habits satisfied with those smaller helicopters. They're fairly unsubstantial and not very difficult to fly, but they also don't do a lot. I'm working on replacing the head gear on my fix-pitched Piccolo with a full variable pitch setup, I have to make the swash plate and rotor hubs, blade holders and flybar mount myself.
I'm also considering making - from scratch - a decent sized Chinook that's capable of lifting stuff, so I can put a camera in it and do remote photography. Being a naturally heavy lifter, I could probably put a considerable amount in it and it ought to be fun, but as I haven't even started drawing it, I'd rather leave it as a dream at the moment and finish my yacht off.
Besides, the difference is usually along these lines:
RC Car: 4 minutes of hectic tyre smoking at 80-100km/h.
Heli: 5-10 minutes of frantic thumb-dancing while you try to stop the thing falling out of the sky
Plane: 10-12 minutes of an almost tennis-match-like viewing with the occasional roll. *yawn*
Yacht: 11 hours of sitting in a chair beside an eski.
Depends on my mood - I like the chair option, lately.
