I’m not sure your rear axle orientation is correct

Those zeros are straight garbage I buy them because they’re cheap OK look at the price $20 for four of them they even have better deals or you can buy 12 of them for about 80 bucks now here is the thing a good high-quality high-speed low drain cordless servo with the same numbers is going to run you about $45 And something that is monstrous so fast you cannot see it transit and has enough power to rip the bell cranks off of your car. Well that may run you into the hundreds of dollars OK never mind any of that other shit like waterproof metal and brass gears ball bearings. I mean you can spend upwards of $300 on one servo so you spending $21 and getting four of them now you understand why we call those things straight shit They’ll get the job done slowly and with a lot of noise interference so there’s that!
