Dyno

[pacificwarriors]

I had this really good idea, but I cannot afford it right now so I will just tell you. In my 1/10 r/c magazine i saw a dyno from kyosho for $160.00. Dont worry this 1 is for electric cars, you could some hpw fabricate an adapter to the dyno and then make a "fake" chassis 2 hold the car in the air and with some type of rollers so that you could connect the peice you made to the rollers and then 2 dymo and have yourself a dyno. the coo part about this is that this specific 1 could memorize the results from other tests. if someone does try this please tell me the results I would like 2 know if it works.

I just found this:

Looks like just the ticket, and it's only $37

It looks like the Mini Z guys have tried it...

That thing is awesome and also alot cheaper than my idea

I have one coming from tower hobby right now I ordered it over the weekend, should be here soon.

It should help in bench testing setups.

take some pictures of it when you get it
i might get one of these

Ok I'll post pics of it.
I remember a while ago it was being talked about a lot but I could not remeber where.I hope it works well enough for the Xmods.

The general consensus I got about it was that you can't take the numbers it puts out as gospel (ie your car probably won't go as fast in reality as the dyno says it does), but you can use it for a reference in testing different setups against each other. That's really what I want it for.

For pics, just look at the second link I posted. There are shots of it testing a Mini-Z.

a dyno, short for dynamometer, measures mechanical power, IE torque, and then calculates horsepower from that. what you ordered is a simple speed checker, it measures the rpm of the rollers and knowing the circumference of its own rollers, it'll calculate the theoretical top speed. anyways, i'm just saying don't call it a dyno unless it's actually gonna measure the power at the wheels

[slugbugg]

You are correct TypeZer0, Tamiya calls it what it is and it is a speed checker.
It is not a dyno, not for $36 LOL but it will still be helpful to me for testing different setups on the car.It will be nice to change a motor or batteries and plop it down on the speed checker and see what, if any difference the change makes.

lol, 36 bucks wont' even get me a single dyno run, let alone afford the tens of thousands for the actual dyno machine

Yep the real test equipment cost big bucks.There is real RC motor test equipment but still that is around $700.00 and up.
