I was talking 16% like this:
www.modelsport.co.uk/modelsport-uk-performance-16-glow-fuel-1-litre/rc-car-products/29346
The manual for my Firestorm recommends 25% but it seemed a nightmare to tune on that. Kept cutting out and wouldn't start for ****. I have read loads so figure I am pretty clued up. Is it easier to tune the car when running a lower percentage of nitro?
thanks again guys
