Hello Arrma Nero community.... this is my first experience with an Arrma vehicle, my second RC but the third in the family. I bought my son a brushed EMaxx for his 4th birthday, in the meantime I bought myself an XMaxx and most recently was intrigued by the Arrma Nero (I was lead to believe I got a great deal on it when the price dropped $100, little did I know it was because of the Big Rock release)!
Anyway, I made the purchase through TowerHobbies, grabbed some Proline Big Joe II tires on F-11 wheelie and outfitted it with Tbonesracing thrasher bumper, center skid plate, wheelie bar and Arrma dirt guards. I was more than pleased when it all arrived within a couple of days.
I got right to it..... Bashing! Two sets of batteries, SMC 7200mAh 65C and SPC 7200mAh 70C and fresh AA cells for the transmitter. Set the ESC, brake on low and the Punch to level four(4).... What a "Blast" to drive it, all is superb! Jumps like a Boss... Wheelies like it's it sole purpose in life.... Drifts in hard packed dirt with insane donuts... And climbing can be fun too!!!!
Fast forward to present day.... About three weeks later! This is long winded, I know but I felt the backlog was necessary. The truck randomly started "acting up". Shortly following power up, the truck drives and steers okay then as if it goes instant Low Voltage... Applies the break and comes to an abrupt hault, with the transmitter trigger held at full throttle! Release the trigger And sometimes it goes and sometimes it needs a second or three. Then the issue doesn't disappear, it's persistent (Extreme Buzzkill)
I have Factory reset the transmitter and ESC to no avail. I thought it may be a resistance issue since I made XT90 to Traxxas connectors.... But this worked great for a few weeks then "bam" all of the sudden. So I tried a buddies connectors, questioning my soldering job, those connections yielded the results! So I wrote to Arrma with my dilemma and got a less than prompt reply due to high volume online support traffic (completely understood), but they're suggesting it was likely the TTX300 transmitter settings (which were not messed with at all) since it was fine out of the box! Other possibility was connectors if I wasn't using the XT90's. Since there's no adjustability to Low Voltage Cutoff that was eliminated as a culprit. My batteries are only a few months old and run my XMaxx really strong (the Nero too until it went haywire)!!!
..... So while awaiting a new response from Arrma, I am still thinking it's simply a failed or faulty Arrma/Hobbywing ESC. (It is indeed a Hobbywing with less programming options, I peeled the double-sided tape)) Maybe a possible capacitor issue????? To rule out any possibility of resistance issue with batteries or connectors I upgraded to Castle Creations 6.5mm, 200Amp connectors! I have since tried the truck and still the same issue... As if, it's gone low voltage or even thermal shutdown!!!! Beyond annoyed at this point and would really like a Hobbywing Max6/8 to hopefully resolve the issue and give more ESC custom adjustability.... I'm even tempted to try my Hobbywing Max6 off my XMaxx but really don't want the double downtime.... And the BLX motor I'm sure is 4-4.5mm connectors so I'd need an adapter for that too.
Please Help... If you can....
