Yes, the new filters work very well.
I ran my new Rossi Pixy .12 in my gas truck tonight and I'm almost convinced this motor will be the next level. I ran almost 11 minutes on a tank in the main tonight (driving VERY hard) and the motor came off at under 200 degrees. It had very controllable power throughout the whole range and wound out like a top down the straightaway..I was giggling it was so fast.
In other news, I've decided that 1/8th scale is WAY SUPER DOPE (especially when your car is superdialed!). Check the Jammin' thread for more info :-)
