yea my dual 6374, 12s4p with 107mm superflys is approaching 30lb. awesome performance but a pain in the ass to lug around.

In case you want more options and donāt mind waiting, thereās an EU group buy on the DIY 218mm ones.
NVM its closed, sorry.
Iām super interested in doing this since I have almost everything for the same setup you have. Would you mind sharing how you managed to squeeze them in?
And why arenāt you using your idlers in that photo?
It looks like thereās ample room for sk3 6374ās just want to make sure you didnāt have to modify anything? As this threads got a little confusingš¤ I was under the assumption they fit sk3 6374ās no probs!!..you are running 15mm pulleys and belts?
Hi, Reason you did not see the idlers because I am still waiting for my belts to come in. What I have in the picture is version 1 of my motor mount (no idlers). Version 2 has a dual idlers. Note: my setup is a TB218mm truck running a dual Turnigy 6374 motors, all 180mm trucks including Caliber, Ronin, Paris,ā¦ will not fit a dual 6374s.

Picture shows 12mm belt. I am waiting for 15mm belts to come in which are the sizes Iāll be using for my final build.

Is that a standard bearing spacer and speed washer on each side?
Yes, they are.
Iāve read that dual SK3 6374s wonāt fit. Clearly youāve proven otherwise, which is fantastic news to me since I can keep my motors 
Iām assuming youāve not made any modifications and just slapped your parts in yes?
I have these trucks on the way but what made the thread a little confusing was the comment that apparently sk3 6374ās wouldnāt fit! Diy.com website says it will fit 2x 6374ās 190kv side by sideā¦so what your saying is confirming what I thought,you CAN run dual sk3ās with 15mm belt/pulley setup,donāt get why people are asking you how you done it??
Though @torqueboards mentioned SK3s wouldnāt fit (or he was unsure, I canāt recall).
All you need is a TB218mm truck or compatible length to run a dual 6374s. No modifications are required as you can see in the picture.

TB 6374 motors have a length of 74mm which is why they make TB218mm truck for their motors in a dual setup. Turnigy 6374 motors have a length of 86.3mnmn which I did not realize until I bought it. I thought all 6374s have the same length, absolutely not the case! With that in mind I engineered my motor mounts so I can accommodate my dual setup with up to ~90mm in motor width.

So you have modified mounts! So with enertion motor mounts they would not fit? Just need to clarify before I purchase motors!
Canāt speak of enertion mounts because I donāt have one in my possession. I always wanted to engineer my own to the way I want.
Fair enough! I think Iāll just go with a different brand of motor to be on the safe side,I donāt get why hobbyking made the motor dimensions bigger as the 6374 as you rightly pointed out is for measurements! Anyway thanks @marcmt88
Sry for jumping in like this. But does caliber 2 10" fit dual 6364 motors?
No they wonāt fit,the most you can run on those trucks is 6355ās dual.
