Gspeed sitting crooked when running on flat ground

[SaltyDog]

Wondering if this is normal or not when running a forward motor mount since there’s a weight bias toward the front left side where the motor is. I don’t notice any performance issues, besides some minor rubbing, but it’s more so just annoying to look at as I’m sure some of you can understand. Has anyone else had this issue?

I’m using the Gspeed TFR panhard mount for the AR44’s with the Hardcore panhard link for AR44’s and Traxxas Big Bores with Losi mini springs for reference.

Is it only under power that it leans?

You might be seeing torque twist, common on softly sprung rigs.

It actually happens when I turn the wheels, regardless of if it’s moving or not.

Seems like the effect of high caster angle

How are your servo end points? If it’s too much the servo will suck the chassis down

Can you get some video of it happening?

I had something similar on my v3 when using the gld and an incorrect length drag link.

Servo end points are pretty dialed in. At the very beginning this was an issue so I spent some time really tuning it.

Yeah, a video is probably the easiest way to show the issue. I’ll get one and post it once I get home.

You can add some preload to the springs on the low side (usually the right side), that should help a bit but this lean isnt uncommon due to the above reasons.

You know I actually increased the angle and it seemed like it helped a little. Turning doesn’t cause it as much anymore. However, now it is noticeably torque twist. So maybe it was a little bit of each to begin with.

Do you know of a solution for torque twist? It leans heavily to the front driver side when reversing, and when I throttle it forward it seems to correct it.

I took some video, now I just need to find a way to upload it. I will say though that it’s far less noticeable in the video footage unfortunately. I did shorten my drag link maybe 2mm and noticed an improvement. Was that the case in your situation as well?
