Thank you

I have one in my dbxle2.0.
it’s a huge motor. What do you want to put it in?

i have an oportunity to buy it new from a dbxl for 100euros, like 100$
the idea is to lower the consomation of batteries, get more runtime

It would fit in a kraton 8s but nothing else arrma makes.

Well he posted in Arrma 8s so there aren't more options.....yet
You need a large pinion!

I run one in my K8S. It does not lower the consumption of a battery.The bigger motors definitely drain batteries faster. I get about 15-20 minutes out of my gensacearespammers 7500 packs. Before the motor I could get 30-45 minutes.

It’s a pig of a motor. Lol.
Odd what does the k8s have in it for a motor. I thought this was it?

1150kv.The big difference is the stock motor is much smaller.

that’s a side by side with the 780Kv and the stock. The 780Kv also has a bigger diameter.

Wow! Didn’t realize that kraton 8s motor was so small.
That explains the long run times. My dbxle 2.0 run times are 12-14 min.

thank you for that photo, does the 780kv fit the stock motor mount?

no. The stock slide has the motor sitting to low due to the diameter difference. the mount holes for securing the slide are also too small to support it with a pinion larger than 29t. I had pictures because I tried it, but I can’t find them at this time. Here are pics of the mount compared to the M2C mount.

Thank you for thoses photos.

So i have to add the M2C motor mount and 8mm slide mount.
does m2c Motor mount and slide come with the srews we need?

My idea is about lower the consomation, i don't do speedruns with the kraton, i just want more run time, so a lower kv motor and a mid size pignon gear.

Depending on your needs, the m2c mount won't fit them as you're still limited regarding pinion size, I believe about 34t is possible with it. I currently run a 42t on a HW sl56113 800kv and I feel like I still want a tad more. You might want to consider the fastlane or ebay mount (check out the sticky thread in the K8s forum).

M2C just released a new slide to support a bigger pinion.

I saw that. I wonder if it's for 1/5 motors or 1/6 motors. I'll add it to the upgrade sticky.

It is for their new motor mount for the bigger canned motors. I’m sure the motor mount and sleeve will work for both smaller and bigger motors.
