Default Revo 3.3 build under 7lbs

I have been out of the hobby for 5 years and just now got back into it and decided on a ground up Revo build. This is my T-Maxx from 5 years ago which I believe was 7lbs 1oz with body, wheels no fuel. I started buying all the aluminum crap thinking it would be stronger and only ended up with a slow and unreliable truck. Ultimately went lightweight and it was more reliable, stronger and handled much better. Wish I still had it now.

Started with a Vantage extended chassis. A-Arms differentials installed. Used Lunsford hingpins to save weight.

Lost 2 oz of rotating mass or over 20%. Used titanium stub axles and titanium U-joint set w/ aluminum carriers on all shafts. The 14 mm hexes will allow me to run a lighter wheel and tire combo and still be more than adequate for a small block.

Edit- I weighed it at work on the Fedex scale, and it's 9.4lbs. ( empty fuel tank, single JR steering servo) .

If I could knock 2 lbs off this thing, it'd be a friggin rocket on the track.

I prefer a bit of weight on mine. I had one at 8pounds 2 oz. and had trouble getting traction sometimes, I went back to about 8#10 oz. and it was much better

A couple of yrs ago many of us were tryion gto build the lightest Revo's to race with. After a season of racing in very competitive events we all found that the revo handles with a bit more weight to it. 8.5-10lbs seems like the standard. Many of us would find better traction and more attitude control while jumping with heavier tires as well. Just an FYI. The truck looks beautiful. On a smooth track the light trucks do well for sure or anything indoors where low end acceleration is beneficial critical to going fast. It was the larger outdoor rough tracks that the heavy trucks did better on. Slayden's, Tim Roberts, Roy Pitchlin's, and many other pro Traxxas drivers never got their trucks too light because they would get all twicthy and harder to keep in control. However with heavier wheels and lighter wheels I think you could use them as a tuning option. Or i bet a light truck like that would run awesome on a nice little .12 size motor. Just an idea. many of us ran the PL Wabash Wheels with Panther tires.

Thanks.

Here's some pics of my old Prohobby maxx. It's longer than a stock (2.5) maxx and uses a bumpbox for starting. This shows it with the revo wheels and Panther tires I started with, but after a few shakedown runs with the taller wheels I switched to a set of standard size velocity wheels with bowties so I could use the stock (2.5) gearing. Please excuse the goofy header. It was a quick and dirty fix to get the thing going and it worked so I just went with it. Ready to drop on the track (including a full load of fuel) it was just over 7 pounds.

Never owned a revo, but all the guys I know who race them favor a heavier truck. The maxx works real well under 8 pounds though.
