Hello Everyone,
First time posting anything about RC since being in the hobby since 2015. I am just now learning the details of the electronics since owning my V1 Mojave. I will try to be detailed and brief. Apologies if a thread was already created about this.
The Questions:
All Stock Mojave V1 except for Flysky GT5 Transmitter w/ FS-BS6 Receiver, a Savox SW-1210SG servo, and a custom made vented tub much like the ones people are using from RC Tubz.
What happened:
I was driving the Mojave in a field near my house when the car suddenly stopped. It lost all throttle and steering. The esc was blinking red so I assumed it was thermals as I was only driving it for about 10 mins. I let it cool down for about 15 mins but it did not run. So I cleaned it up and brought it in to see what happened. I found the Receiver was dead; this was my second receiver that died within a year so I assumed it had gotten wet like my first one that died. I had 3 other receivers to test (details ahead).
Test:
Conclusion:
I came to the conclusion that the Internal BEC is fried. Unless not being able to reprogram the ESC on 3s is an indicator of something else(I'm no expert). Even though I really don't want to spend the money, I have decided to upgrade the electronics rather than have a Mojave paperweight.

The Questions:
- Has anyone with a BLX185 w/ fried caps bypassed the caps with a external BEC (I would remove the positive wire from the esc to transmitter)?
- Would doing so cause other problems within the ESC or other components in my system?
- Can I use the vxl-8s esc (found one cheap) with the BLX 2050kv motor if I only use 6s and change the connectors? (Looking for longevity)
- Would the Firma 150a esc from the v2 work with the BLX 2050kv motor? Its just under $80 on Jenny's RC; I see it has the extra caps and I assume that was the upgrade to the BLX185 (besides the smart capabilities and options).
- Since the BLX and Firma have HW components, can I expect the same build quality out of a Max 6 combo?(Hopefully Not)

I found the Receiver was dead; this was my second receiver that died within a year so I assumed it had gotten wet like my first one that died. I had 3 other receivers to test (details ahead).
Test:
- I have a fully functioning ERevo v1 with the mxl-6s castle system (which btw is still going strong 5 years later). Decided to use this as a testing rig.
- Already knew the receiver was dead because it did not light up and had a burnt smell
- Hooked up the Servo to the ERevo and it did not have any response. The wires where ripped near the rubber grommet(figured my fault how I removed it). Repaired the wires before the testing.
- Thinking the servo caused a short, I put a older Traxxas receiver(used because I was willing to sacrifice it) on the BLX185 without a servo connected. Popped and smoked as soon as I turned it on.
- 2 receivers left
- Thinking it was because it was an old Traxxas receiver I hooked up the stock STX2 receiver. Popped and smoked
- 1 receiver left
- I checked the motor and the back had gotten loose so I took it apart and checked all of the bearings, Looked good so reassembled and set to the side no longer connected to esc
- hooked the esc up with only 1 3s battery. Didn't know if it was enough to power it but it did power up
- I connected the esc only (still only on 3s power) to my Traxxas receiver out of my ERevo and everything powered up and I did not lose power to the receiver.
- Tried to reprogram the esc but it would not allow me to go through any of the options or set the throttle, brake, neutral on transmitter
- It would go into programing mode but would not have the green light to tell me what category I was choosing
- Dumb in Hindsight (I am just trying to figure it out), but thinking it was because it was only on 3s I connected it to 6s (again only esc and receiver). Turned it on and immediately Pop and Smoke. No More receivers
- I know its not the battery's because I used two sets of HRB Batteries that I tested on my charger with all 3 cells being balanced at 4.2v. They also work well on ERevo.
Conclusion:
I came to the conclusion that the Internal BEC is fried. Unless not being able to reprogram the ESC on 3s is an indicator of something else(I'm no expert). Even though I really don't want to spend the money, I have decided to upgrade the electronics rather than have a Mojave paperweight.
- Max 6 with 1650kv motor 20t pinion
- power hobby cap pack
- castle programable external BEC
- large heat sinks/powerful fans for esc and motor w/separate battery pack
- new fs-bs6 receiver in a donated Traxxas water proof receiver box from my Nitro Revo
- a brushless digital servo (don't know which one yet)
- taller metal servo mount, or spacers
