probably more like, http://www.okhobby.com/product.php?id_product=1164

But it appears they might have descent cheap stuff coming. 4 pole motor, 5s esc http://www.okhobby.com/product.php?id_product=1234

Well, the motor is in. But it has changed its size and appearance!

Bondonutz 05.25.2010 06:59 PM

All that photoshop work for nuthin' ?

It is a unusual looking mill, looks like a WWII German grenade ? Probably do the same thing ?

I lol-ed at that last bit! :lol:

dimensions: 53.4x96.4mm, 39mm can

So the can is 39mm and the fins are 53.4. By my calculations the can is significantly smaller than the Castle 1717 by volume (cylinder = Pi x r2 x length)

1717: pi x (23^2) x 85 = 141,262 mm3
KD: pi x (19.5^2) x 96.4 = 115,158 mm3

giving the 1717 22.67% greater volume (and therefore BIGGER)

Bondonutz 05.25.2010 09:39 PM

I'm not going to check your math, I trust you. JK

suicideneil 05.26.2010 12:31 PM

Wtf is that thing suposed to be, I'd be amazed if it could fit in any truck with those rediculous fins. And yeah, its rather unlikely to be a match for the 1717 if used in the same setup. Kinda.. nay, seriously lame. :no:

Andrew32 05.26.2010 12:36 PM

thats some pretty sweet photoshopping. Making something seem bigger than it is......daang..i think im goign to start photoshopping my :lol: when i send pictures to you know who:party::party:

Here are a few of Dan's comments about the motor:

http://www.hpibajaforum.com/forum/sh...t=76408&page=2

interesting that he writes: "The motor came through with an entirely different look than expected - Just as long, but narrow"

:neutral:

simplechamp 05.26.2010 04:17 PM

Doesn't seem very professional. I mean, how can you commission the production of your own line of motors with out really knowing exactly what you are producing?

Bondonutz 05.26.2010 05:14 PM

I know this is not the correct thread but that FD Baja conversion just looks really cheesy.
Why is the motor facing the oppisite side of the spur grear, doesn't look reliable at all Nor does the 158.99 motor. What kind of qaulity/efficentcy can be had for that cheap of a price ??

Wow, Mike has great prices on the Castle line !
But I was really refering to the 1/5 scale motor not the samller 1515 sizes.

I even kinda have my doubts that the 1717 with it's 6s Limit being enough to be really efficent for a 28+lb baja ?

I had the same thoughts - but then I also wondered what exactly Castle was targeting the 1717 for? It seems too big for 1/8 scale trucks but too small for 1/5 scale.

asheck 05.26.2010 06:41 PM

I know, that's why the, just saying, as the implication was double, not only does 159 buy alot these days from Mike, and you'd probably be better off buying a undersized 1515 for your application, then spending 159 on something as listed.
IMO A 39 x 96 , offbrand, doesn't really seem to me like it would be any better then a 1515.

Perfect overkill for 1/8 scale

Seriously, what a pile! I can't believe people would actually pay money for that hack job. Thank God Mike doesn't make garbage like this and I know his baja conversion will sorely put the kershaw junk to shame.

Chadworkz 05.27.2010 12:55 AM

So, in the above picture, 1 or 2 motors turn a spur-gear on one side of the Baja that rotates a shaft that has a pinion-gear attached to it on the other side of the Baja that then turns that actual spur-gear of the Baja? And the bearings on that shaft sure do look small, and it looks like there's just one bearing on the left-side by the pinion-gear...

Anyway, I agree with what has already been said, that contraption above is just a total mess, with completely unnecessary components, parts and layout...and it will probably bend on the very first impact, or maybe even during installation, heh!

Overdriven 06.01.2010 10:33 PM

I happened to be in my lhs when a guy brought this in so I snapped a few pics. Its a King Motors clone with every (king motors) aluminum part installed, running really tall rear tires. Proline moab XL's on 23mm adapters I think, alot taller than stock either way. Thats a 2215 1Y in there powered by a hobbywing 150, he's got 2 6s in parrallel. :slap: Claims he's seen 38mph on radar and it has more in it, but was limited by space at the time. Also told me a 5b body won't fit, it'll hit the gear on the jackshaft. No mech brakes on this one, don't know if its possible with this kit. I do know he bought the car from Dan setup like this, but with a MMM. He's hoping the hobbywing won't go up in flames like the MMM did. :lol: Yes I explained why neither would survive very long and what he needed to do. He then mentioned Dan told him a 1/5 esc was coming from hobbywing that would solve the problem. Anyway on to the pics.

Edit: Chadworks, there are two bearings supporting the shaft, one on each side. They go in from the gear side, I guess that way the gear helps hold them in place? Dan told him the dual motor setup had synching issues so it was scrapped. But he kept the shaft so you can't run a 5b body without cutting it for gear clearance.

I did not think I could be any less impressed but these new pics did it. It looks like pure crap. So the dual motor idea did not work so instead of redesigning the mount he just hacks that together. And best yet the 5B bodies don't work on it?! What's the point?

Total garbage, I can't wait to see Mike's conversion put that pile to shame.

That's the blind leading the blind alright.. Kershaw "designs" I think I could do better with finger paint. He might want to rename his operation, something like "Rube Goldberg RC" maybe.

A freakin jackshaft? And why do the 'metal' gears look suspiciously like aluminum?
No interest in 5th scales personally, but man the HPI deserves better than that.

That thing is disgraceful, no other word. It really lools like he pulled the gears from a Walmart toy.... thanks for the laugh Mr. Dan!

That's pretty much why I posted it. Its hard to tell what you're getting into from the pics I've seen of the kit so far. From what I can tell, the spur(?) gear on the left side will hit the body, don't know about the right side. I didn't get into it much, was more concerned with trying to point this guy in a better direction as far as electronics are concerned. I'm still wondering how anyone could sell this kit powered by 6s on a MMM though, especially without mechanical brakes. And if it isn't clear on the pics, the mount doesn't tie into the rear of the car at all on the left side, only the right.

What's_nitro? 06.01.2010 11:43 PM

Hmmm, I see a bent chassis in his future... :grrrrrr:

fastbaja5b 06.02.2010 12:04 AM

Yet another reason to keep my 5B and 5T as they are with the whipper snipper motors. These brushless Baja conversions have been an ongoing tease for yrs now, and so far all that's available is either c#ap or "coming soon.... if ever...."

This was the first thing I noticed when I saw at the pics...I mean, his mount goes right to that hole in the chassis, and there is absolutely no excuse for not simply making a tapped hole in the mount for a screw to tie the chassis to the mount. It's right friggin there!!! Why in the hell didn't he make a simple mount for the hole in the chassis that's right there! Just doesn't make sense.

Maybe I just like things, especially things on such large vehicles, to be braced well when they are going to be under great forces...I don't know, maybe it's just me.

What's_nitro? 06.02.2010 02:52 AM

It's not just you... :no: :lol:

TexasSP 06.02.2010 09:53 AM

I am also highly suspect of what grade aluminum he is using and the whole thing looks to be water jet cut as well. I would want my tolerances a little tighter. It's also clear that in the pieces he gave no consideration to the forces of impact as I see several break points.

Bondonutz 06.02.2010 10:01 AM

Pretty Sad, wonder if Chris Fine had a hand in the design ?

Overdriven 06.02.2010 11:03 AM

^^^ lol @ Bondo. I agree with the bracing issues, a few simple changes to the side plates wouldve provided provisions for more bracing. I particularly like how the side plates are like a pedestal where they meet the bottom plate. Look at the left side under the motor pinion to see what I mean. Supposedly it's been through some tumbles though and has held up so far. Who knows how bad those tumbles were. I'm no expert in machining, but I'd say it was water jet cut also. The edges don't show that "machined" look and there are no signs of any additional operations performed to clean up the edges.

Edit: If anyone wants to post these images elsewhere in this or any other forum you have my permission. I didn't want to start a new thread so I just put it here.

I think Chris Fine would have incorporate some kind of motor clamps like he does for the LST conversions.... Still on the same level of crapsmanship. :whistle:

suicideneil 06.02.2010 05:21 PM

^Dont forget the bottle-top to protect the rear of the motor shaft...

Im highly un-impressed also; KD used to make some alright stuff and had a pretty good reputation ( rc-monster in a shed as I put it ), but lately Im not enthused at all- he ony seems to design his stuff & then get someone else to machine it, using the cheapest materials possible to increase profit margins. :no:

Chadworkz 06.02.2010 07:02 PM

Looks like greed is rearing its ugly head...oh well, I never owned any of Dan's parts, and never will, because I never liked them in the first place, but now they are even worse, hence why I said he just got greedy. The sad thing is, Dan is a really nice guy, but his business has gone in the toilet, and may soon get flushed.
