Speed runs are usually the most ideal situations with alot of prep and tall gearing.
Im going to make the assumption that a stock out-the-box savage 4.6 wont hit 60 mph but I could be wrong. Anyone with a GPS or radar needs to clock it and let us know!

wow....60? dont think so. I think the fastest topend wise savage has been the Savage LE. From what i read it hit 38.2 MPH. that stock. stock savages are all under 40 mph by far....ne where from 34-38. 60 mph is something which i havent heard of unless you heavily mod your savvy w/ the baddest motor and run high gearing....even then...i dont see 60 mph a possibility.

It's most likely Kph, and not mph... 60 kmh is 36 mph - which would be about right...

For all we know they could have accidently clocked the wheel spin when it lifted off the ground. I am more likly to believe the 67kph that was registered just prior to the 96kph. which is 41.63 mph. The savage is fast but to jump from 42 mph to 60 mph in 1 second I dont think so.

It wont hit 45+. Jumpin High, your Savage does NOT hit 49 mph. No way! I need videos.

OH MY GOODNESS. You are the dumbest person in the world if you believe this. How does it go 64-96-64 km/h in a micro second? Friggin' radar gun garbage. Pitiful if you ask me.

Gay is all i can say. Nitro rc cars can bairly get going that fast some of them, how the hell do they expect a thing that weighs as much as 4 cars to go that fast? especially when RPM doesnt go high enough.

A clocking device hitting the wheels of a Savage with a 3speed transmission, 20T/47T CB/spur combo and 6in diameter wheels would would read about twice the actual vehicle speed. That means if you have a radar or laser that reads 70MPH clocked the surface of the wheels. The actual speed of the Savage is about 35MPH. 60MPH? More like 30MPH since the wheels are so easy to clock on a frontal run (the Savage coming at you). The wheels at a frontal Savage profile is actaually a very large area, anywhere from a third to a half of the frontal profile is strctly the moving wheels.

Looks like radar in the vid. Radar usually catches the speed of closest part of an object. In this case its probably is the body of the truck. laser however is more precise and can pinpoint objects better. So perhaps its picking up the speed of the wheels. (I'm radar and laser certified)

Laser with a scope sighting device (like a police grade laser clocking device) is the ideal tool since you can aim for the body and never clock the wheels. I have a Bushnell radar gun and wish I had a police grade laser clocking device, but that would cost me no less than $2000 to obtain one. []

A speed trap with laser triggers is the most optimal clocking device to accurately clock how fast a Savage, or any RC, is moving.

Or strap a GPS to it and be done. Its the most accurate aside from shooting it w/ laser and thats usually out of the question.

Forget laser, forget radar, forget GPS when it comes to RC. Use this instead.

1. Mark out a speed trap of a minimum of 100 feet. Clearly mark the entry and exit lines. Get your truck up to speed and head towards the trap.

2. Have someone with a stopwatch ready. As your truck hits the entry line, your partner with the stopwatch starts timing. Stop timing when it hits the exit line. Hold your truck at WOT all the way through the trap.

3. Now divide the distance of the speed trap by the time it took your truck to go through it. Take that number and multiply it by 0.682.

4. That's the top speed of your truck. Don't feel bad if your truck isn't as fast as you thought it was-we've all been there.

Mathematically this makes sense, but there is IMO a HUGE flaw with this system too.. It's the unreliability of anybody to be able to click the stopwatch at the EXACT right time - twice.... Maybe if you did it a thousand times and took the average... But I bet clicking within five feet of a WOT Sav flying by over a thin line ain't all that easy.. You could easily be minus 5 on one side, plus 5 on the other, etc..... Yeah it's all d=rt, but if your d isn't constant, neither is the rest....
