Correct.

Guys, Is RX4 as strong as RX8g2 or stronger? Can it be used for 1:8 racing or software is different for smoother acceleration?

The RX4 has fewer FETs than the RX8, so it can't handle quite as much power. However, I've seen several people use them in an 8th scale buggy without any issues. Truggy is probably too much, though. Just follow the KV restrictions posted on the website and run a fan.

Software wise, they can be set up in the same fashion, so no problems there. The default settings are a bit different, if I remember correctly.

Did you notice, that I refer to rx8 gen2? gen3 seems much stronger.

Yes, the RX8 gen2 is still more capable than the RX4. Definitely a smaller difference than the Gen3.

What is your exact scenario you are debating?

One of my old ESCs just burned in 1:10 truggy, thinking of putting waterprooved by me rx8g2 or buying rx4 (instead of rx8g3) already waterproof. Or buy rx8g3 and waterproof it, but it is a little too good for this rather small car. Sure when in need this esc will go to 1:8 buggy too. I was just hoping rx4 is waterprooved rx8g2

I think the RX4 is your best bet. That way you don't void any warranties by altering a Gen3 and it could still be a backup for your 1:8 buggy.

Out of curiosity, what method were you planning to use for waterproofing the RX8?

I use MG Chemicals 4223, the best I know, it works that good (watch at 16:20) : RX8 is one of easiest to waterproof ESC's, I have 2 of them made and no problems at all

I stopped racing about 4 years ago and all the nitro tracks around me had to close. It's starting to itch again to race, but I can only run electric on the tracks nearby.
I had an mbx6 with a Tekin RX8 gen 2 and 1900kv tekin motor about 7-8 years ago, but electric wasn't a big thing back then and I sold everything to focus on nitro 1/10 and electric 1/10. But during the time I had my RX8, it failed on me with a lot of white smoke. It was replaced by the European distributor at the time without too much hassle, but I'm wondering how the GEN 3 is doing for you guys in a 1/8th scale buggy on outdoor tracks. Are the failure rates lower than than with the Gen 2?

Nobody that would like to share his experience?

Personally, I've had 2 original RX8s fail on me, 0 Gen2s fail, and 0 Gen3s fail.

Locally, I have yet to see anyone else with a bad RX8 Gen3 that wasn't caused by physical damage. Short motor wires that pull on the posts are the most common issue as they either break the posts or flex the board to cause a failure or the motor tabs bend and cause a short.

Individual failures don't make a trend. I've never had a Gen3 but I've been using Gen1s and Gen 2s since 2009 and have had exactly one failure where a Gen2 just stopped working after landing 1 1ft high "jump". Never really made sense, but that's what happened.

Gen3 are much more reliable then the old ones. And rctech is pretty dead now.

Thank you for the feedback.
Thank you for the feedback.
Where do you race now? I stopped racing for about 4.5 years, but looking to get back in 1/8th electric since I don't want to travel anymore to race nitro.
I'm thinking of going to the circuit in Torhout. It looks pretty nice for 1/8.

Are there more active RC forums these days? Or is RC dying in general?

Forums have lost ground to social media these days.
