Does any one know how fast a Silvercan racer has been able to go ??

I mean the Johnson 540 motors (Silvercan) you get with a Tamiya Car...

Lunchboxer

Any limit on the voltage?!

DriftingDragon

8.4v

The 3-speed Tamiya semis seem awfully fast with a silvercan, but it may be an illusion. I'll clock it tomorrow on 7.2 I don't have 8.4 at the moment because I don't have any IB4200 packs with me at the moment to utilize my 1.2 "NOS" cells with...

I'm going to say 13mph would be a pretty impressive achievement with one of those 'things.'

Lunchboxer

LOL, no, I meant, to the original question on how fast the silvercan will go.. so I asked what's the "rule" that we have to follow...

Did he meant how fast a silvercan will go for 7.2V? Or 8.4V? Or 14.4V? Unlimited voltage?

I know for sure a silvercan can be quite quick when you up the voltage.. doesn't mean that they will live long this way but they are pretty tough motors..

On my Clod, I run them with 14.4V.. been driven my Clod for many packs.. the motors are still fine!!

So that means, the silvercan can probably go up even more...

I am sure a silvercan w/ 14.4V in a pancar can do a good 35-40mph!!

Lets Stick to a 1:10th Chassis

Lets make the limit 8.4V

Open choice on ESC and Gearing...

sloppyG

can I take the RC with the silvercan to the edge of a cliff and drop it off?

I bet that'd be the fastest one for sure!

Lunchboxer

Put it on a direct drive chassis and gear it up.. maybe 20-25mph?

paintstikker

The Blackfoot Xtreme has a speed of 16-18 mph with a silvercan on 7.2v....

TIGER76

Id guess 15-20mph on 7.2v and maybe 20-30mph on 8.4v depending on chassis/gearing etc

The Hedgehog

Easy 25 mph with a F103 chassis. Probably more if oyu gear it high.

Yea my F102 came with a silver can and I'd say it probably went around 25 with 7.2v

I could easily see it doing 40 in a light car (pancar, F1, etc) with the right gearing and a good amount of voltage.

magnat

So no one has actually tried to get a top speed with one ???

Lunchboxer

I guess people generally don't do it because it is not the right way to get speed by overgearing...

lee172

interesting thread, smoke those silver cans!!

The Hedgehog

Might as well, we know they can handle 14.4 volts (LB's clod)

paintstikker

Heck, my TXT which is about 15-20 lbs. will hit 20-22 mph with the silvercans on 14.4v.

magnat

Well some of my Mates race Silvercans and they estimate that the fastest possible top speed is 44kph..
They got this estimation based on the maximum RPM they have ever gotten out of one..

So it just got me thinking, if it was possible to push the envelope further...

But what voltage did they get those rpms at? I assume they're racing them with 7.2v. Double the voltage (or more) and you'll get quite a bit more rpm out of them.

Thats only about 27mph, I'm certain you can get more mph than that with the right gearing and voltage.

TIGER76

The trouble with silver cans is its like a lucky dip some are good and some are bad they can range from 14,000rpms upwards on 7.2v

carmadmatt

What sort of gearing would I need in an F103GT for high-speeds using a Silvercan? Someone said from a vid that they thought it was a hopped up motor in my car. So I've got the Hopped Up F103 coming, I've got a Silvercan and an 8.4v battery, I fancy giving this ago if I can find a good enough road. How will I measure the speed?

Find a large parking lot and mark two lines about 100 feet apart. The lines don't need to be exactly 100 feet apart, but you do need to know the exact amount of space between them. In reality the longer the distance between the lines the more accurate your results will be.

The basic idea is to get your car up to it's top speed before it enters the speed trap (the area between the two lines). Then with a stopwatch time how long it takes for your car to go through the speed trap and do a little math to find your speed .

Divide the distance (in feet) by the time it took to cross the speed trap (in seconds). Then multiply that number by .682

carmadmatt

Thanks drevil, will try that when my car arrives, if all goes well a video will be posted up. Gearing will be as the car arrives with a carbon chassis, ball-bearings (I think), stock silvercan, Tamiya TEU-101 ESC and a Kyosho 1200mah 8.4v battery.

One more question, what tyres will be better, foam or rubber? My foam's are 40 shore, 30mm at the front, 26mm at the rear.
