Big Rock Dual Motor Mount

[Logan's_Rcs]

Hello all,

Recently my friend designed up a dual motor mount for the arrma 3s line.

We are trying to gauge if there would be any interest in this, we were thinking it would most likely be used for speed runs. It could also be used with higher kv motors, i.e. two castle 1410's or likewise for extreme amounts of power with minimal heat.

To be honest it probably isn’t worth the trouble.
I’ve got the fastest 3s line speedrun car at 175mph to date with a single motor and have issues with drivetrain failure. Adding extra weight of two systems will just put more stress on the drivetrain.

With that said it’s still a really cool idea.

What would be much much better suited is to build a single motor motor mount that is setup like the 6s line and bolts thru the chassis with a support underneath.
To finally get rid of the limitations of the stock motor mount.

Wow that's good timing..... Me and @Tex Koder had slightly started to think about something like this. Pretty cool that you got something figured out!

Very unique!
That's some Creative solution!!

Something to consider for my Project : SRX

I'll be watching this development.



PS: If you need a custom Enhanced Chassis Spline Block to "hold up" that upper motor..
I've already have something designed & produced [and can be tweaked to help support that second motor.] > https://www.arrmaforum.com/threads/...e-block-w-integrated-motor-mount-brace.55813/

Does anyone have a picture of what the rear diff input looks like on the 3s????

Agree. I’m surprised nobody has designed this. Shouldn’t be that complicated but maybe it’s just not worth the trouble.

This is the spline for the front and rear that a spool/driveshaft needs to attach to.

Unfortunately making a part with the female version of that can be expensive and has deterred a couple people I know from making anything so far
