Seems like a nice idea, provided that everyone stays honest and nobody flames each other [&:].

People tend to exaggerate a bit much especially when it comes to perceived speed or their r/c cars. Ain't no way a VXL with 26/76 gearing will do 60mph on a 7 cell nimh pack. It is hard to get to that with my car on a 3s Lipo with that gearing.

According to that calculator my stock VXL Stampede should go 48mph on the stock 19/86 with 11.1v lipo.

But according by my GPS (which is correctly calibrated) it goes 43mph.

I am sure the GPS adds a bit of weight to the car and slows it down, and most GPS units you have to run a good distance at WOT to get an accurate reading. But that is why it is called a calculator, to get you close to what your speed should be, if you want accurate use a radar gun.

I have no idea how fast I go, I am sure its in the 20 mph range or less, LOL. anyhow, anyone try one of these hot wheel radar guns? http://www.amazon.com/Mattel-J2358-H.../dp/B000EHLB0M
I have seen them at $20 and less, could be a fun addition to the lineup, radar the rc's (or the kids riding the bikes and scooters, yell at the neighbors for driving past too fast, etc)

Yeah I made sure I had a looooong open parking lot and ran at full throttle for several seconds. I did several passes for consistency. The weight of the GPS will slow the truck down but it only weighs 150g so I doubt it made too much difference - certainly not 5 mph difference. I did do the runs with the body on the truck so that may have affected top speed.

The gearing calculator does not account drivetrain loss etc etc. I doubt th emotor is running the exact RPM's you used to calculate also. Remember a battery under load is not the same as a fully charged.

But anyway, adding more weight will not affect the top speed of your car whatsoever, just how fast it gets there.
