frog was pretty all time. Pinion (sp?) gears lasted about 2 goes though. there was a usa mob making them from alloy I think.
My favorite was the sand scorcher. Hard to drive on the dirt, but it looked so cool. My mate had the Holiday Buggy with the small 380 motor when I got the sand scorcher, then as I outpowered him he got the super champ. now that was a good one. Still I think it had a live axle too, so crap to drive.
After the frog I got the road wizard and had that for a while, got a fox that we never made work. A mate gave me the lambo countach and it lived under my bed for about 10 years, never did anything with it other than toss it out.
I never got the hotshot, wished I did. But i was well into bmx more by then.
Actaully, I had an airboat from an Aussie company, built it up, had the glow engine running and never got to use it. Was riding with it all in my "Tiger" school bag and got hit by a car on the way to the lagoon while on my bmx and it got crushed.
