Thanks for the info. What size tank do people normally run? I have the stock viper tank and I usually have more than half tank left after the practice and races.
For the TT40, I'd go w/ a 4 or 4.5 oz tettra bladder tank. You'll have to hog out F1 a tiny bit to get it to fit, but it's really easy to do. If you move up to a Nelson or Jett (428) you're going to have to go to a 6oz tank. For those I use a Jett 6oz slim. You'll have to move your throttle servo w/ that setup, but again it's pretty easy.
Make sure you read the Viper modification threads that are around. Even w/ a TT40 you'll pull the firewall out of them.
