I had a few as a kid but got fedup waiting for the battery to charge for it to only run for 3 minutes
I had a Tamiya Fox and then moved to a Mardave Marauder. Things got no better with that as I used to use a rubber wheel fixed on my dads electric drill held in Black & Decker Workmate. That was better as I used to fill the tank up with the engine running. That was until the throttle jammed one day and it went flat out through my mums greenhouse!
Built a few after that such as the Mardave IC stockcar and an original Mardave Mini but never raced for a further 26 years!
Now 26 years later I have a Mardave V12 and loving it!
