Atomic MRX - 2500KV Hardbody | First Drive Impression & Setup #miniz

I made this video on 9/23/2024.

I made this video before the DWS for the MRX was released. I’ve already preordered the DWS kit and the 1.5° caster which I will probably have by the time this video goes public.

This car in the 2500-Lipo Class is very easy to drive and competitive! It never felt like the car was going to traction roll (after front tires were broken in) and although the rear of the car was planted, it never felt like the car had a lot of understeer. It had a little push compared to my race car (other car) but then again I did not fine tune this MRX at the track. If I did that, I know I can get the steering I want but the car as is, was already so good even with that very minimal push. I also want to add that the the left rear wheel hub was overly torque so when I spun the diff without the pinion, it was NOT spinning on its own. I found out after the test (at home) that the hub walked when I tightened the set screw. It moved and leaned on the left bearing. Also, I was having so much fun with this car that I forgot I wanted to test the car with the same wheels and tire compound as my race car. I didn't get to do that and if I did, I think I would've had the same steering as my race car. Too much fun driving this car with the R8 body. :D If you’re looking for a good race car that’s under $300, this would be it!

TJ - you have said a few times that you polished the ball studs on this car - how did you do that? My guess is something like... tighten one down to a long setscrew, stick it into a drill, and run it in a rag with some Brasso. Is that what you're doing?

TJ, thank you for all of the great videos. Your time and effort are much appreciated. Could you tell me what spur and what TI axle shaft you are using for you Kyosho ball diff builds? I did some research and did not really come up with anything.

Hi TJ!

I ordered an MRX and it will be arriving sometime next week. I’m looking to see what optional parts I should buy as you have had more time with what it may need. I want to build it as soon as the parts come in. I noticed your links are all out of stock. Do you recommend the side wings and the aluminum chassis? I’m not sure what the material is of the standard chassis that comes with the kit. I’ll place my order for the parts once you suggest all required optional upgrades 😊

Keep on making these awesome videos!

How does this compare to the rx28? New to 1/28 trying to decide which one.

Great video TJ curios I noticed you are running 2500kv lipo in the car. Is that car legal to run in lipo stock class our track locally made unsensored illegal to race they now require a blinkey esc and tech them to make sure they are in blinkey mode. I am still fighting with my mr04 i think the board is bad I heard a rumor about a bad batch of boards, gonna order up a replacement and see if that solves the problem.

Is this the car what everyone races now at the track? Is it better than the reflex racing ?
