Little spinner 4 upgrades

[graeme]

New speedo fitted, trying a castle ice2 160HV, going to test it tommorow and try the data logger on it.
Its a bit heavier than the scorpion so will have to loose some weight somehow.

I should copyright my ideas from you guys lol.....

Post a pic of the data from a spin up

Those new parts are looking good Graeme, espicially the weapon gearbox, looks very robust.
The Triacs are awesome little machines!

Out of curiosity, why did you choose to include a bevel gear set in the design?

[graeme]

Thanks sam yours is looking great too, I used the bevel gear because the motor wont fit in on its end
theres only 65mm height inside the robot.
1st spinup data below if you click on it it gets clearer. I couldnt spin it up any faster as the base would spin round on the garage floor. I dont have a steel sheet for the magnets to hold it down and i probably didnt need a 160A

As if your current draw Is that low.... 360s getting re geared.

[typhoon_driver]

That's running off 10 cell isn't it? So the current draw will be a lower than the same setup on 5 or 6 cell if i'm right in thinking?

[PJ-27]

That you are. Plus I'm assuming a spin up that slow wouldn't draw too much current.

[typhoon_driver]

So Dave I would recommend doing a few spin up tests and seeing what the current draw on your own machine is before changing out ratios etc

[Mouldy]

210amp ...I know why my current draw is high/ls4's is so low... Was just shocked at how low ls4s draw is... Even on a slow spin up.

I have screwed the base down to stop it spinning but still cant spin up any faster, the motor is going out of sync for some reason if i throttle up quickly and it screams. What settings do you use on your esc dave ?.
