I made the series of this video from mid-May to mid-June 2024. Test were done in two different track layouts.
It took a long time doing this comparison between the RX28 G1 and RX28SE G2 with the 2500KV motor due to the weather change and me not testing the cars on the same day, prolonged this comparison. I know it's not the RX28 G2 plate but I also have the G2 plate and I also HAD a full RX28 G2 car brand new while I was doing this comparison test but after the Part 3 result, I sold both of my RX28 G1 with G2-plate as well as my new RX28 G2 and kept my RX28 G1, RX28SE G2's. I just personally prefer the brass plate, it feels (to me) easier to drive than the G2 plate. Here's the video I made when I converted my brass to steel plate: • Reflex Racing RX28 G1 ...
Before I made this video, I really thought that SE would be .10 seconds slower. I didn't expect it to be the same as the non-SE (but if you want to be technical with the numbers, the SE won this comparison on stock steel bearings with grease). Both cars are doing identical lap times. Both were consistent and doing same fast laps. So if you're trying to decide which car to buy for 2500 or 3500 class, you can't go wrong with the RX28 G2. Or if you're thinking of "upgrading" to the RX28 G2, there's no need. Your G1 is as fast. You just need to make sure that there is no binding in the frontend because the G1 is using plastic ball studs and the G2 is using aluminum. There is also the G2 upgrade kit for your G1 if you want to go that route.
If you plan to eventually get in the Mod class, definitely look into the SE because its versatile. You can use 2500, 3500 or Mod motor and its going to be a fast car in any class! Even in 2500KV class, this car is not slow. It is fast even if its 7 grams heavier than standard RX28. I have tried the non-SE G2 plate with GL 4500KV and 5500KV motor and it's hard to drive the car at that speed. This is why I don't use the RX28 non-SE car with any motor above 3500KV. Just 2500KV and 3500KV, but I'm sure someone can set it up in Mod and be fine with it. I just wasn't able to do that. I also like to build the SE better. To me the SE (G1 or G2) is a lot easier to put together for whatever reason. Maybe because there's more room to work on? Who knows... And you can also change the way the car drives by changing the shim in the lower pivot. Something that the non-SE doesn't have.
Note that the ceramic bearing in the RX28 G1 is over 1 year old (but still spins for a long time just like it did when it was new! Here's the video link: • Fast Eddies Ceramic Be... . The bearings in the RX28SE G2 are standard but they're brand new with grease (Reflex Racing stock bearing kit). I use the exact same Jomurema hard body with lexan roof and spoiler. I also use the same sets of GNB Green LiPos charged at 1.0 amp - LiPo Balance (not LiHV).
Sorry for the long video and thank you for watching!
Update: June 19, 2024
I just went and cleaned the bearings in the RX28 G1. I thought they're ceramic bearings, they're not. The bearings are PN Dry steel shielded bearings in the front (4), lubed with Yutori 003. In the motor mount, those bearings (2) are Fast Eddies rubber shield removed and also lubed with Yutori.
The RX28SE G2 has Reflex Racing OEM bearing set but flushed out grease and lubed with Yutori 003.
