Stock ESC and motor?

[alvinm]

I posted this question in another unrelated thread, so I figured I'd get a quicker response here..

Will the stock setup handle two 3s lipo's, or a 3s and a 2s with the same mah?

[DjFlipNautikz]

don't take my word for it but if i am not mistaken i read that it can handle upto 5s if you install a UBEC or if you remove the red wire from the connector of the esc to the reciever and install a seprate RX battery pack.

my friend however which is on here told me he tried 5s with out any modifications and that everything ran cool.

but i am a n00b so hopefully some more experienced people will chime in.

Good Luck

6s no. The motor will handle 5s but I'm not sure about the esc. 2s+3s same mah ok

I would suggest to stick with 4S otherwise you will run the risk of failure or shorten the life of the motor.

Its plenty fast with 4s, its just that I have an extra 3s pack I would like to use..

Try the stock setup with an x640.................... If you run a 2s and a 3s they need to be the same mah and "C" rating!

I have a question. I run my MC parallel instead of series so i have two Turnigy 4s batteries 5000mah. BUT they are slightly different C rating one is 25c- 35c and the other is 40c - 50c

is that a problem? even though i think it is a little late for that as i have already ran my MC about 10 times with those packs.

It could cause a major problem right off the bat or it could abuse one batt that it will eventually give up, bloat, or explode...................

Well I check the temps of the batteries. I usually only do a run of like 8-10 mins and the temp is always about 100* - 110*. Would it be better if I run on battery at a time? Even tho it's a hassle to re tape and stuff.

I'm using the Grim 42x55 prop now, will the x640 perform better?

I ran a 5400mah 3s 20c and a 5400mah 2s 20c and had no problems... everything was cold after a w.o.t. run for about 5 mins... and I havent even upgraded cooling...

btw im running the grim 2300kv instead of the regular 1800kv if that makes a difference, idk...

[Rob DeAngelis]
