Default Re: Brushless kv choice for Bomber

I was considering the castle 2850kv as well...seeing as you can get it with the mabma x esc for just over $200 I feel its a pretty reasonable price. I plan to do a mixture of rock crawling and bashing with mine so I think this would be a good compromise. I've also been looking at the tekin pro4 hd 3000kv motor as I see its got great reviews, but its also double the price of the castle motor. any of you experienced guys care to chime in on that?

edit: ill be running on 3s with an otherwise stock bomber.

I'm running a mamba x with 2200kv 1515 Castle motor on 4s, way more fun than the Castle SCT 3800kv on 2s.

Which is the dimension of 1515?Did you fit it without modification?

Holmes Hobbies now makes a 1/8 size motor if you want to go nuts

Otherwise there is the puller pro R 4100kv on 3s that is designed for races

I was wondering a 3674 2650kv motor would be faster than a 3660 3800kv on 3s with suitable gearing?

Holmes 3500xl on 3s. After breaking the front and rear axle housings in 2 days. The 3500 came out. The 2.2 Showdowns also came off. I would stay around 2500-2800kv.

2700kv on 3s is a sweet spot for the bomber IMO. I would still personally run the 3500 because I like excess wheelspeed. Or the 2700 on 4s.

I went with the Holmes PP 3500 in my bomber kit this spring and am super happy with it!! I'm running just 2s now, I have no 3s yet. Man it's fast and can crawl very well too, IMO.

The 1515 slid right in, no fitment issues like when I had it in my Yeti. It is heavy though.....

I have vanquish motor mount so I think the weight won't be a problem although I would choose a little smaller motor like 4068 or 3674 to avoid the extra weight of a 4074 since I will run only on 3s.

1410-3800kv with 3S-45C seems to run well. With the throttle curve programmed in the Mamba Monster it crawls nicely well and bashes pretty fun (current setup hits 19.5mph)

With a small 2S-30C pack it goes good at crawler speeds and still runs a long time. Not quite as fast at the top end though.

My drivetrain:
Castle Mamba Monster X ESC
Castle 1410 3800Kv Sensored Brushless Motor
HotRacing Steel Pinion 32P 16T
HotRacing Steel Spur Gear 32P 68T
Axial 2-speed Transmission with Hi-Speed Option

This is not the stock spur / pinion gears.
You put a Wraith transmission in it?

Not stock at all for pinion/spur. The large shaft on the Castle motor needed a new pinion and I wanted steel so that meant steel spur also. Found the combo I liked. Running without the dust cover though since the spur is barely too large for it.

Stock transmission with the Axial 2-speed kit.
