I have an Arma Senton 3s blx, and a Traxxas Corvette 3.0 brushed. I’m not super good with tech work and was curious if anyone had any knowledge on this. I want to switch the motor, esc and possibly receiver. Does anyone know if switching these things will work without any adaptions. I’ve replaced electronics in my cars plenty of times but switching completely different brands I’m not to sure about, will the titan 12t have enough power for the 4x4 senton? And can the Covettes transmission take 3s power?

The Traxxas Titan 12T is a very weak motor. Virtually any other motor will work better. Even the Horizon Hobbies Dynamite 12T motor is better than the Traxxas Titan 12T. But if you want a really good brushed motor, go look at Holmes Hobbies.

Other than that, yes you can replace electronics with a different brand and it will work fine. The motor and servo sizes are all standard, and the ESC and receiver don't need to be standard sizes because you can stick them anywhere with foam tape.

The Traxxas 4Tec's limiting factor isn't its transmission, but its tire size. All touring cars have tiny tires that spin easily. You pretty much can't overload their transmissions unless you're using super-sticky tires on a perfectly-clean track, because they'll just spin their wheels if you mash the throttle.

Thanks for th info. My concern with the transmission was the gears/gearing. What would you say would be the best motor and esc combo for upgrading the Corvette 3.0. I want to take one of my cars and get it to the 80-100mph mark. Currently my 3s Senton is my fastest at 50mph, which has become slow to me. I want to go to 80-100mph but not sure what the best way is and I don't want to drop a ton of money. Which car would you say is best for upgrading to that speed? Traxxas 4tec 3.0 brushed, Arma Senton blx 3s, or Slash 2wd brushed. From my understanding the motor that the Senton comes with can go to 4s but not the esc. Am I wrong on this?

Unfortunately I can't advise on making an electric touring car go that fast. My fastest touring car was a nitro, at 67mph. It's probably easier to make an electric touring car go that fast because you can just stuff a ridiculous motor and battery into it and gear it to the moon, whereas nitro engines already operate close to their physical limits. What I can tell you is that regardless of the platform, at that speed aerodynamics is going to be incredibly important for stability, so you need to work your way up to that speed making adjustments to the aerodynamics as you go. If you try to go for 100mph all in one shot, even if you make several practice runs, you're going to discover an aerodynamic problem that sends the car flying ass-over-teakettle at the worst possible moment (i.e. the fastest speed before the car smashes to pieces). You're also going to need belted tires, whether they are foam-filled or solid rubber, because the tires will be experiencing thousands of G's of centrifugal force at that speed. Foam tires can also work, but are prone to becoming dangerously unbalanced with no warning if a big chunk of foam rips off. Getting hit by an out-of-control RC car with sharp metal bits at 100mph is much worse than getting hit by a nice round baseball at 100mph.

Very interesting and some good points I didn't think about. For wheels I knew I would need belted, and I was thinking about doing solid rubber. But aerodynamics I did not take into much consideration, the 4tec 3.0 corvette while being aerodynamic probably is enough for that speed.
Working my way up a little more probably would be wise as doubling my speed will be very difficult.
Overall I think you do have some very good points. With that in mind I will definitely need to figure out how I will get there (i.e what motor, esc, battery) and will aim for a more reasonable speed, like 70mph.
Gotta say...your very knowledge in the hobby.
Appreciate your advice and the info.

Standard RC car bodies are almost never good for 100mph without some kind of modification. Remember unlike a normal car, a RC car body is hollow on the underside and can act like a parachute if too much air gets under it, and wind gusts have vastly more effect on a 4-pound RC car than they do on a 4000-pound real car. You need lots of extra downforce to counteract the possibility of the car being launched off the pavement by bouncing over a pebble and getting a bubble of air under the body. The fastest class of RC race cars, 1/8-scale GT cars, run bodies shaped like doorstops to ensure they have enough downforce to stay on the ground.

The doorstop looking bodies are the classic 1/8th scale nitro. The 1/8 GT class has much more normal looking bodies (but is slower as well).

Definitely agree with that. My Arma Senton has on many occasions at full speed had the air pick it up sending the car flying, thankfully this car has been extremely durable and has had nothing break from this. Like i said i think ill got for a more reasonable speed and will go for 70mph. My thinking so far is to buy a Spectrum Receiver, Spectrum 130a esc and motor.
