Yesterday got practice with my GX7R on Buggy and GX5R on truggy (first time ever with .21 on truggy, always been using .25 GO before).

Both engines just got about 12-15 tanks each, still very tight and giving me just 7 1/2 minutes GX7R and 8 minutes GX5R ... any tip for this weekend ? lol ! i have a very important race and my engines still tight so even when good power, they are driniking too much fuel, hate that ...

thanks
