tuna rc

I have an RC8 and love it. The only problem is that I run out of nitro quiet quickly. Does Team Associated or another complany make bigger fuel tanks for these? Also, I am running a stock .28 motor. What percentage fuel should I use?
Thanks

its nothing to due with the tank, its cause your running a .28 engine. i would remmend a .21 engine, or you could use a carb restricter in your .28 ,and that could help and, a smooth throttle finger.

.28's suck gas you prob need fuel every 5-6 mins. Try not to hold it wide open very long and make the change from no throttle to full throttle smoothly. But no matter what you do the .28 will suck alot more gas than. .21

But will I lose speed with a .21?

no a .21 engine has, more top end and good enough torque.

If your bashing its ok, but on a track you will loose to that .21 cause when your filling up at every 6 minutes the 21 will go 11 minutes (well my Nova does). So a 20 minute race your filling up 3 times to a 21's 1 time.

so i would NOT lose speed with a .21? and can i still use 30% fuel? Also, what is a good motor?
Thanks

a good .21 will kill that stock .28

look at the Vspec or Ninja

Most people use a 21 in a truggy also just because they get better mileage and pit stops take time. Nobody on a track can go as fast as thier engine will allow them too because you have to slow down for the corners and time your jumps and such. My best lap times have been when my motor was dyeing and was so slow i couldn't wipe out or spin out and i drove very smooth because i had just enough power for my throttle happy finger. fast is fast but slow can be fast also.

Also for any race you can only use a fuel tank with 125cc capacity in a buggy.
