10 minutes is easily achievable with the V-Spec...

Mike Craddock, the UK Kyosho Team manager won a recent meeting at slough UK by not having to pit for fuel for the whole 10 minute final with a V-Spec...

The amount Alex races and practices, it wouldn't surprise me if he has got through a lot of fuel, although 50 gallons does sound excessive over a few months, are you sure on your timescales qwerty? as I havent seen Alex say a few months?

PS we drive in all weathers here, if we didnt we would never race
