lol, nice bro, looking forward to seeing that!!!

Eddie,
When are we able to get the ESC programming CD/ROM and USBadapter?

My Feedback: (1)

What voltage does the ESC provide to the motor cooling fan plug? Will it be whatever voltage the batteries provide? If I use (2) 2S lipos in series for 14.8V (i.e. like a 4S like Joacim did), will the fan get 14.8V. Looking around on ebay, I see 5V fans (7.2V max) and 12V fans (15V max).

i would think 7.2 would be fine, its just going to put out whatever the esc puts out to it.

well, I walked through the programming of the ESC using the SET button and LEDs - it was a little tricky, but it worked like a charm once I got it figured out - and the manual was right on - I adjusted the low voltage cutoff up to 3.4V to better protect the lipos and reduced the initial acceleration a bit to stop the tires from always breaking loose and lengthen the battery life a bit

My Feedback: (1)

well I had a chance to try out the new parameters in the ESC - I had increased the low voltage cutoff from 3.0 to 3.4 because I had an issue with one of my packs getting too low on voltage - strangely enough, with the new setting, it ran the pack voltage even lower, lower than it ever had before - and it was not the pack that had gone low before, so it was not due to a problematic pack - I am going to try and set up a DC power supply to connect to the ESC and see if I can adjust the power supply voltage down until the low voltage cutoff activates - maybe that way I can verify the ESC settings and figure out what is going on

you can always get a vot alarm for the lipos. i have 2 of them and they work good. when the volts get to 3.4 it sets the alarm off.

I was thinking about those, Adam, and Eddie had mentioned them too - which one do you use?

ehroof

these are the ones i use, cheap price for some insurance and testing purposes:

thanks, Eddie - I am going to get one of each of those - they are the same ones I saw at Hobbyking

ehroof

they work really good

found a check for $2.47 shipped.....

I already bought one of each of those from ebay LOL!

how long should you store lipos after charging before you need to put them at a storage voltage? or is that necessary? I have heard about discharging them to a lower-than-full voltage for longer storage - do you do that?

ehroof

nope, i just let them sit after i fully balance charge them...... have had no issues to date and using the same pack for 3 years

sick6stang

Let me know how you make out. I got my buggy to do wheel stands on the rear wing. But I cant open the throttle the whole way with my 4s 40c 5000mAh Trunigy battery. I will be posting a video of what it is doing when I ever get my spare parts I need. They should be on the way. Secondly...... When are the programming components hitting US soil??

My Feedback: (1)

i just made a wiring harness to connect the 2 lipos in series for 4S and I picked up a 10t and 12t pinion to gear down a bit but have not tried them yet

sick6stang

ok, what c rating on a liposhould we use in the buggy?? IDK what goes with a 80 amp esc.

divide the mAh of the pack by 1000 and multiply by the C rate - that gives you the max amps the pack can deliver - for example, a 5000 mAh 30C pack can deliver 150 amps - if our ESC is 80A, then a 5000 mAh 20C would be enough since it could deliver 100A - from what I have been reading, it is a good idea to have a little more available from the pack than the ESC max
