Default why fuel tanks not larger?

Just a curious question based on my observation that your fuel tank capacity is limited for racing (is this correct?). Why can't you run a big fat tank so no stops are required? Is your total fuel consumption for the race also limited? I am just curious, no other reason for asking.

the only answer i have is that having, a bigger tank would just add too much weight on r/c cars.

its like F1-Now there are no fuel stops=Less fun for spectator's ect.. having fuel stops.. adds a exciting element.. and makes it a bit more tactical.. in my view.. and weight.. bigger tanks.. would need all the buggies to be re designed in a way for the larger size ect..

Fuel capacity is limited for racing. This is so one person doesn't have an advantage over another and that is why engine tuning is so critical.

Many tracks have races have a 45 minute to hour-long Main. A near perfect tune can go about 11-12 minutes on a 125cc tank of fuel. To go an hour without pit stops means that the tank would have to be about 5 times larger. That's a big tank for a 1/8 car.

+1 i would be a huge fuel tank to run through 45min. mains

The spectator thing is the only reason that would make sense to me. If larger tanks were allowed then it would be up to the driver if he thought he could cover the entire distance faster with a larger tank and less stops or a smaller tank and more stops. That would be fair for everyone.

its about strategy, things like nascar wouldnt be as good w/o pits. It brings more then just driving into the race.

It's not a bad idea to keep a truggy tank around for your buggy if your running an Open event. Mixed nitro and electric, any powerplant goes type race.

I think its a ton off fun having so many different types of 1/8th scales running the same race. Kinda like old school real racing when cars were still basic and noone had them figured out yet. I think we're about to step into the best, most interesting club racing ever in the next few years. Electric, 2 stroke nitro, 4 stroke running together is going to be really interesting.

Hopefully the fun class tracks don't die off to the rules oriented ones.

A OS .28 XZ and truggy tank in a buggy make a real equalizer when your running against E buggies.

But it adds weight.

A 4 stroke with a huge cooling head and correct gear ratio would get way better fuel economy.

Pit stops are part of racing. They add an element of strategy to racing. That's part of the excitement in racing nitro for me.

Where i live at local club races we dont ge too many 1/8th so we just combine them. Its pretty fun actually

A little birdie told me some are trying. But none have the guts to mass produce one, because the first co. to make one is going to get hammered by Momo racers blowing them up.

The few truggy conversions out there are getting alot of attention, I know I'll never forget the last one I saw.

And as long as racers are willing to spend $450+ on a $180 2 stroke motor......

Then why not limit EP batt capacities at 4000mah?

It's so unfair for GPs!

150cc would be nice At least, I can bash longer between refills
