Current draw question, using eagle tree....

[Over_revO]

Hi guys,

Me and my friend bought a RC8T and we did a first test yesterday,

we didnt had the tires in time so we used other.

I used savage tires with a 14T pinion (16t was in kit)
2200kv cc combo

my friend:
MMM esc Neu 1515 1.5d 14t pinion with badland fitted on rulux half-up(like LPR)


we tested with Eagle tree, on brutal wheelies thats where we had the highest peak, neu 1515 1.5d= 181 amp

and for me with 2200kv 178 amp

my friend did a couples wheelies then ran very slowly climbing a hill and the esc smoked.


i stopped mine, we later went out, i used his badland tires (smaller diameter)
i pulled 173amp peak on wheelies on asphalt now., but normal driving is ok, mix like 150 amp max.
tested top speed, 54mph and may be 56mph was possible.

thats a bit too fast for bashing anyway,

so we installed a12T pinion,

peak of 170amp on WOT from standing wheelies, but other peak were 150 and less, normal driving under 100 and some small peak in the 120s.

estimated speed around 50mph....


We tested braking, low speed load etc and the highest peak came with brutal take-off. or mid to WOT instantly....

my question is, how can my friend smoke the esc at low speed?
most esc that i seen smoke was at low rpm, but at low rpm our current draw was always under 80 amp....

Is there anything that affect the esc at lower speed?


Im really trying to figure out what is happening....

The highest watt was 3800 i think with the Neu 1515 1.5d


We also tried the Neu 2.5d 1650KV on 14T and it also pulled 178 amp!
but had only 1860 watt!

on the 12t with 2200kv it produce 4.25 hp
and the 1650kv it produced 2.5hp but peak amp was higher than the 2200kv...


thx for reading all of this, im trying to not smoke my esc

It just seem like even geared for 35mph it will pull those amp.
On low speed it really seemed good.


I will try to get a eagle tree log data today and post it here so you will guys have a better idea of what im trying to explain....


Shortened question:

Low speed climbing is ok? if no why
high peak but normal current draw on normal driving ok?

Thx!
