Losi 1/8 ESC works great with latest firmware

[auto2]

i had put the new firmware on mine. it did get 50 percent smoother. which made it half a smooth as a MMM. worked 10 more minutes and died.

... I'm curious how well or bad mine will be, I've ordered one today. In that online-shop it was on sale for 127 Euro, which is about 169 usd.

I have already heard about the new rotors, and have asked the wholesaler for germany/austria, robitronic. he told me that they're about to receive some new rotors. they have the same power-specs, but a new black winding. I detectet at mine that the kevlar-winding slowly getting loose...

but so far I'm happy with the motor, temps have been ok and performance is good. by far better then any chinese-crap. it's a four-pole motor, which gives better torque and is better for the partial load-use we have in cars (the two-poles don't like that much, so they get hot).

anyways, the overall-quality of the motor is good, so I ordered the esc. I hope its a good one... at the moment I use a cheapo-chinese esc, modded with fan and fat caps, and it works - funny thing - just flawlessly (just the breaks suck). for a price of 30 euros...

I think losi xcelorin needs some positive public relations, the standing of these products isn't the best at the moment. I 've read about so many failures of e.g. mgm controllers, which cost a sh**load of money, still the're supposed to be top of the shelf...

at least the xcelorin motor is great quality for that money (about 90-100 euros), it's hard to get medusas here.

I wonder if modding of the xcelorin esc with some extra power caps would make sense... any other feedback is highly appreciated.

You should update the firmware before doing anything else to it. A few features will be locked and some will behave different, like the brakes for example. Mine still works fine. I haven't felt the need to add more caps, as the ESC doesn't get hot at all. The limit is 3000kv. I tried a two pole 3600kv motor and it just cogs. I tried a 3100kv 2 pole more and it was a hit or miss. Still works well with a 2700kv 4 pole motor. I haven't tried the 4800kv 4 pole motor yet, to see if it works or not.

Here's a vid of the ESC running on 6s A123 and a 2700kv motor.

I installed the lastest Firmware Losi released for the 1/8 ESC. The ESC was smoother on takoff and ran fine for a whole pack. Second pack started off good. But it let the magic smoke out when it cogged for second.

That is how mine went and it took 2 months to get a replacement...so I bought the MMM and haven't had a problem...I have the new replacement Losi in the wrapper still...and given your results, it will stay there a lot longer.

I took mine apart and saw the 3 fets with the missing smoke compartments.

For those interested, here are guts of the ESC.
