So I got my 2016 Raider Blx and tore up the dogbones and axle and output shaft shortly after I got it. Searched online and seemed it was a common occurrence so I ordered a few different length dogbones for the redcat. Ended up using the 90mm Redcat ones. After running those for a while the stub axle was getting torn up again. Trying to figure out whether the dogbones are measured pin to pin or overall I pulled out the messed up arrma dogbone that came with the car and measured. It was 80mm pin to pin. So I ordered another 83mm that has the "83mm" etched into the middle of the dogbone. I received it and measured it and what do you know it's 83mm pin to pin. So I installed it and it's a perfect fit. The pic of it installed is pushed all the way into the output shaft so as you can see it only leaves enough for the compression of the arms. So there issue resolved on that.
Next is the Redcat 90mm dogbones. Perfect length but the pins are a lot smaller which would explain it tearing up my axle. The HPI pins are the same as the Arrma's but I bought the 6x86mm which is just slightly too long to where it would bind only when the springs are compressed so maybe an 84 would be good. Here are also some pics of a side by side of the Redcat pins and the Arrma pins. Hope this helps
