It seems to me if you are going to bench test this you would probably want to swing a flywheel to get any kind of results. I had to get the truck up to top speed to get the result I got. It took a few tries, and another thing I noticed was that if I hit the brakes that when I watched the meter the voltage would climb faster when I came to a stop than if I was to just coast to a stop. This would also further support that the battery was somewhat being charged when the brakes are used.

in a rc or not it will work the SAME
its not hard to add a load to a motor usen a 12v motor on a 12v battery.....

both breushless motor and the brushed 12v motor running the Same direction
then when you hit the breake on the brushless motor the Brushed motor will try to keep it from stoping and or add drag ALOT longer than if it was in a rc.
and is a constant and repeteable over and over.

and my esc is a Xerun 80A-R the black one.

" this is in opposition to your blanket statement that esc's were simple unlike hybrid cars. "

in a hybrid cars regenerative braking is usefull and is setup to regulate the regenerative braking voltage and charge with it.
and i do have an open mind thats why i tested my esc like i have ....
cause if it had regenerative braking i could use that for a few things that i would have liked to try.


if it did have regenerative braking the Thread would have went a completely different direction like check this out ..????????..
and its usen the egenerative properties of the esc.
but that was not the case here.

If memory serves me correctly someone did a test that showed regen effects by using the tekno electri clutch with mech brakes and then swapping in a regular pinion and using motor brakes. They had longer runtime with the pinion and motor brakes, indicating regen braking was recharging the battery somewhat.

My understanding of motor braking was that the esc placed a load on the motor during braking, as opposed to the vehicle placing the load on the motor during acceleration. Maybe to simplified, but with DC current it has to flow one way or the other. I do not see a method to "ground" it out, as it is a closed system. No wire leading to the dirt. Unless you attempt to disapate the braking force into heat, like a mech brake does.

oh paralyzed it did not rain here last nite .......
but i just might still be able to find some fair sized puddles for today....

i am putting the esc and motor back in the RedCat in about 10 minutes from now and the batteries are all charged up ready to go i just need to reprogram the esc before taking it out first .......
then its time for "splash down"

I created another page on the calc site to explain regen braking using Arct1k's formulas he posted earlier: http://scriptasylum.com/rc_speed/brake_power.html

I'd really like to add exactly how much charging current is achieved, but not sure about those formulas, so it's pretty basic right now (hence the beta status).

i got this in two parts as the first part like a dumb fool i only had a 1 gig card in my camera so this video is short .

it looks like its sitting odd cause a rock was caut under the left rear swing arm .

plus i have found Why it drifts to one side .....
as the front comes off the ground the front tires start ballooning but thay Dont balloon at the same rate so as the front lifts off the ground one of the tires is still in contact with the ground pulling it that direction.

great vids..

maybe it's drifing to one side..
1) drive cup is loose
2) wheel hex is stripped
3) pin for wheel hex loose or broken

instead of using epoxy, you could probably use thermal glue to waterproof the electronic.. but it may take a day or two to settle..

I think im going to Lock the center diff.
then i will have more power to the rear when the front lifts and when the front lifts thay will only spin as fast as the rear tires and would stop all the pizza cutters.

Thanks :great:
i just cleaned it all up and all is perfect
it Only pulls if one tire on the front is still on the ground then pulls to that side........ if i pull a HARD fast wheelie and get the front tires off the grond fast it is straight as an arrow.

Some heavier fluid in the front diff will help keep one front tire from unloading and pulling the truck too. Thanks for starting the lively discussion on a topic I started to forget about. Just remember its a forum and true emotions can't be relayed in text easily. Plus these guys like to rough you up a bit, but all in good fun.

i will try that first

no Damage and Nice and Clean again......
