Totally planning on stuffing that 550 in my 15lb+ 1:4 CJ. How about waterproofing a sensored brushless motor/esc combo?

Nice work, looking forward to seeing some video.

Will you be selling/making the sensor wires to go with your motors? If not could you reccomend any certain brand?

On 2s it will be very manageable otherwise.

is this for the 550's or the small ones

funny guy!!!!!

anyhoo, I cant wait for these man, great work!! I run one of your old "CrawlMasters 3014" "OUTRUNNER" in my scale scx10 JK at 10 pounds and LOVE it to death!! soooo smooth! cant imagine how smooth these will be with a good esc!!

BUT IM IN and want one!!! you should hurry on that esc too

thnx HH for your killer "Stuff"

I was asking questions in this thread befor he had pics up....But yes..I
thought this was the tech section for the sensored outrunners....

But I
will still be purchasing some of these high powered monsters for a
project....Keep us updated!

Please let us know what the max RPM is when you find out? I am saving for batteries and want to know if I should plan on a 2S/4S sestup or 3S/6S setup.

Summit trans is already on the way. Can you say ludicrus speed?

Initial fun will be had in Pepe though.

Can you order a complete Summit trans somewhere? Or did you have to buy all
the parts separate? Or did ya find a used one? Sorry to ask this in the Holmes
tech thread, just curious....

Ebay has people parting out brand new Summits all day long.

I dislike Ebay but sometimes ya gotta do it.

JohnRobHolmes · 11-16-2010, 05:59 PM

These should be good for 60k rpm on all models. The amp ratings I was just stating were for the 550 size.

Oh my........

holycaveman · 11-16-2010, 11:10 PM

I run a 700 wt continuous outrunner and its insane in the top truck. I can't see 1600wts with normal axles.

But the 454 sensored sounds like the new ticket for 2.2 crawlers.

Can't wait until they are out

will love the reliability.

Rootar · 11-22-2010, 12:10 PM

bump for an update!

JohnRobHolmes · 11-22-2010, 12:23 PM

Nothing new yet. I managed to smoke the sensors in one test motor, stupid mistake!

I should have a test vid of the 550 size within the week. The low speed control on these is just insane. The issue is that I may not be able to get them manufactured with all of my design features in high volume, as some of my features don't jive with the lamination machine process.

Almighty Malach · 11-22-2010, 03:36 PM

Don't care, I still want one

between one of these and the new HD gears for teh losi I'm getting pretty excited.

losikid · 11-22-2010, 04:26 PM

I've been wondering, whats the price tag gonna be on one of these. Also any plans of a hh brushless esc or at least mamba max combo?

JohnRobHolmes · 11-22-2010, 05:57 PM

I am working on a compatible ESC, but the mamba max will be a good one too.

Actual prices will have to wait for a sale thread, I can't post that here. The USA version will be more expensive than the China version for sure, and both will be priced similar to other high pole count motors available. Looks like I may get both versions (usa and china type) of the 550 available at the same time.

Tryker46 · 11-22-2010, 09:03 PM

We await the awesomeness patiently!(kinda)

White Stripe · 11-23-2010, 06:39 AM

Don't you get like 1.5hp for every 750watts or so? So this thing will have like 3hp? That doesn't sound right to me but I just googled it. I mean ya 3hp and who knows what torque would destroy 1/10th parts. I think I goofed somewhere in my calculations.

JohnRobHolmes · 11-23-2010, 06:47 AM

750w is one horse, more like 745 watts to be exact.
