TRX4 DEF..motor upgrade

[Captn Danford]

hi folks..got the TRX4 Defemder..just wondering what Brushless motor uprages would be good. are the motors pretty changeable and what sort of spec do i need..for Brushless..

Anything based on a 540 can should fit. For a heavy rig like that I would recommend at least a castle copper head esc ($120). I'm also kind of brand loyal to holmes hobbies for motors- and I love the torque of their outrunners

I just got this system for my Redcat GEN8V2. Works awesome, and at $160 on Amazon, fairly cheap for a brushless system. Also, this is designed specifically for crawlers.

Solid option! The low end control on the fusion is buttery smooth and solid

Honestly, I'm not really sure why you want to upgrade from the Defender's stock system already. While my stock esc crapped out, the motor I feel works just fine.

Heck yeah! Here's mine in the Redcat.

Oh it's RC girl. She had a awesome video from the crawler event she went to some ni e rigs in it.. and a awesome crawler spot.....

Yeah I traxxas has to put some more R&D into their electronics. IMO. So I don't even think I will build my TRX-4 with the stock esc. I'm think the castle sidewinder. The HW has a better drag brake though. Nice stall and reverse bud
What tires are those the tread is sweet and looks very grippy grippy

Initially, I thought RC Girl is just a YTer trying to sell a channel through sex appeal, but she's actually legit as an RCer.

Let me tell you, that Fusion has crazy drag brakes!

I run Holmes Hobbies in all of my crawlers.

Those are Proline Hyrax with the dual foams. They work very well, but I don't feel they are worth it, for the money, since the much, much cheaper Traxxas Canyon Trails performs just as well.

I thought the same thing when I saw RC GIRL. Thought she was maybe a wife of a RCer trying to get veiws.. But nope she is legit.. she has some good videos. And puts in the time to do stuff rite. IMO

I personally won't upgrade to brushless unless I want more torque and speed out of it, or want something more power-dense (e.g. I have a car with limited space, but also don't want to compromise power output).

If going brushless, any 550 sized sensored brushless motors would be a good choice (around $200). The Castle Mamba X and slate, Castle Copperhead 10 and slate, Hobbywing Axe, and Hobbywing Fusion are popular sensored brushless setups. Holmes Hobbies motors are great as well, and I've also seen them paired with Castle ESCs. As for the kv ratings, it really depends on what you are looking for. If you want it to be a lot faster, the stock motor is around 1800kv, so anything higher than that will be faster (ideally no higher than 2850kv if you want to crawl as well since higher kv motors heat up faster). If you just want more torque, and speed seems fine, 1800kv to 2300kv is a good range to choose from.

I thought the same thing when I first saw one of her vids. She's a pretty lady, that's for sure. But I have watched her for awhile now, and she is pretty cool too. I'd definitely hang out with her

class replies folks..thanks..the fusion does look cool..and yes totally agree the RCgirl is class. easy on the eye and seems.t know her stuff class.thanks guys and gals

Well, the only reason I want to upgrade mine is because I’m really hard on it, which caused it to die recently, so I’m wondering what might have a little more durability for a guy who is not easy on his machines. Also might just be that I use it more for trail use rather than rock crawling, I find I end up sending it more than I should. Maybe I should just sell my rig and get a slash? Don’t know.

Those and Tekin are pretty popular. I have a Copperhead 2280 and love it. Holmes and Tekin are on my list.

You may want to go up in kv if your trailing it so it wont be screamin.

Hate to say this but it's the traxxas electronics not you... their electronics suck.. I'm about to start my trx4 build. And I will probably throw a copperhead or the SW4 in it. Just because I don't trust or like traxxas electronics. And I have alot of traxxas kits. Starting back in the 90s. And they have always been the same electronics suck hahaha. You could always upgrade and also pick up the slash. It's a good SC truck..

I got the 1080 sitting here. I'm torn through. Between the two castle or 1080.the 1060 is for the hopper build

The Fusion would not be a good choice if you want more speed.

Huh, that’s interesting. Because as far as I can see it’s the motor, because the steering still works and the electronics are lit up(however I don’t know how to test of it is actually broken), and after I took the motor off and turned it by hand it made grinding noises and other weird noises, so I’m fairly certain it was the motor. There was also a big mud buildup in the motor so I thought I could take it apart and clean it out, but I couldn’t figured out how to take any the main inner casing off of it. But how exactly are the electronics bad? Like, what about them stops working or doesn’t work well? I’d like to see what is actually wrong with it to see if it is actually the electronics. In any case though, I need a new motor, because I tore the original apart to try and see if I could clean it and that was a very dumb idea. It’s in lots of pieces now.
