OS took a good ABC engine that came with and air filter discontinued it for and engine with an ABL with out an air filter and went up about $50 on the price.
Most kits and RTRs these days come with air filters, and universal filters don't always fit, so it makes perfect since they no longer include one. I'm with you, changing the metalurgy could be a bad thing, only time will tell. I'm on gallon 3, and no signs of slowing down.
One other thing being I own a Savage I keep up with what OS VG 30 owners have to say. I will not go in to detail, as I do not want to up set any one.
I wouldn't put anything on typical monster truck owners/bashers, most of the time they don't know what they are doing. We all know how quickly a NOOB can kill a perfectly good nitro motor.
FoamyVictim I'll let you know when I head out to B&T, I don't thank I can in the next few weeks becaues I'm pretty bussy, but I'll let you, I have been wanting to see a 21vg just to see how good it really is.
We're there on the 2nd and 4th Saturday every month, so come and play when you can!
