Crawler King (mod) need help, motor stall, overheating?

[inebriatedmarmoset]

just a thought, some people dont realize. i like your rig though. i have been considering either the team integy crawler coversion with strc chassis, do i have to mount steering servo to the axel with these parts, i basically have a stock wk.

right on, man. yeah once i started using that motor cleaner I've never gone back...it's made the hobby so much more enjoyable behind the scenes and has cut my maintenance time to 1/10 of the time but still gets the same results and prolongs the performance of my rigs.

But yeah, if i'm not mistaken, the stock wheely king has the servo up in the chassis as did the stock crawler king. i still have a lot to learn as i've only been in the hobby for several months but have grown on the CK as a project, not too big of community of WK/CK crawlers out there, but for the most part i've found on this forum and others that the servo mount over axle mod would be the first and best mod to start out with if you want get on the path to some serious crawling. i mean out of the box, the ck was cool, fun to play with, but not really a contender as far as crawling goes. and as soon as i mounted it over the axle with the kit i got from ckrccrawlers (including links too, the ones in the pic above at OCRCraceway), i immediately noticed a difference in performance, you get soooo much more steering and control which was the main complaint for the ck hands down. i did up the servo which i would also recommend doing at the same time to be able to have it bite when you need to while turning, i sprung for it and got a hi-tech digital 7955tg which has given me more than enough torque but im sure you can still get the performance you're looking for with something not as big of a powerhouse. I also did have to play around with it to get the right "fit" adjusting the steering links constantly and checking the max end points so that i wasn't stressing the servo, causing potential damage to the gears inside and would also produce alot of heat. and with that digital servo, im also planning on upgrading my TX to get the end points precisely set and safely get the most out of the servo. it took a while actually, since i sort of had to dick around with it curiously but carefully, but it was still fun nonetheless.

the servo mount kit i got was here
http://www.ckrccrawlers.com/ckrc-aluminum-wk-steering-kit-p-2279.html

but it mounts it at like a 45ish degree angle and i worry that the small clearance between that and the battery bay may cause whatever probs for the servo on like drops where i it would easily get in contact with the battery bay

I've been looking to try out either of these mounts here

http://www.rcguy.com/product-p/me-009.htm
or
http://www.punkrc.com/index.php?mai...oducts_id=29&zenid=1c0hi6fuu3p4to7tddkkllf9l5

to see which may provide better clearance, as soon as i do, ill post it here, although with the one from rcguy it requires you to rotate the shock mount 90 degrees to the rear of the axle and doesn't come with any extra steering links, which came in as a handy replacement when my strc ones broke off, ;-)

Either that, or what i've also found here on rccrawler is that alot of peeps just make their own, which would be awesome, and there are threads with templates to work from if you have the tools/time/resources, (i've been looking at this one here http://www.rccrawler.com/forum/showthread.php?t=64145) i would love to do that and would take pride in the fact that its something you produced from your own hands, which is half the fun in my opinion, but i think thats a bit later down the line for me, though its another route you can take if you can do it :ror:

and the integy crawler conversion kit looks pretty sweet, haven't found alot of feedback about it on rccrawler, although i do notice alot of integy bashing just generally here and there heh, but that kit looks like it would still bump up the performance, i've certainly been looking to get some bent links, might be considering that kit myself! the chassis is also next on my list, and was also looking at strc's for starters, not sure what else is out there yet haven't really done the research yet, if anyone else can offer suggestions???

again, i know i've got a several months but def still feel like a noob so that's just my 2 cents from my exp! sorry for the rant heh

and thanks for the support! it's been awesome building this rig

cool thread

i actually dont crawl but i just thought it would handle better with the crawler coversion.

 

[inebriatedmarmoset]

ahh gotcha, yeah in my opinion i think it would, maneuverablility and control are key factors when im out on the rocks, but maybe you wouldn't need the entire conversion kit, just the servo mount alone would improve it, also upgrading/extending the links woud give ya more stability, you can also get some clockable C axles and high clearance steering knuckles to really get more steering, like i mentioned above, RCPcrawlers sells some for the wk

 

[notcrawlin]

clockable c axe?

im sorry what is a clockable c axel? and what liinks could i extend just a little , oviously the bottom links are the first to go but which set. i assumed streching anything required the streched driveshafts so i thought i might as well get the whole kit . if i am wrong please respond to which links upper and lower would work.

 

[inebriatedmarmoset]

Off topic. inebriatedmarmoset is a very cool username. You should see a drunk spider monkey though!

heh thanks...! ...Not just a clan, but a lifestyle! :mrgreen:

yep, those crazy legs are quite the indulgers!

it's the "C" shape axle for each wheel,
like this

and in the front, with a clockable C axle you can "clock" it to the 2nd position (notice the two holes for screws in the pic) tilting your turning radius slightly more upwards making more towards being parallel to the ground.. like with mine, they're steering at a slight downward angle kind of turning into the ground at a small degree and the the extra position for those C's will help raise that a little if that's the case with your WK

these are the one's i got from RCPcrawlers
http://rcpcrawlers.com/product.php?printable=Y&productid=837&js=n

though im not sure which would be a good set, not a lot of ones being sold out there, and i couldn't find the exact length for the integy set you were looking at but i do like the bent links on those, but that's more for clearance over rocks, but actual length, im not sure, you can try to keep searching this forum, i haven't found alot of threads about that particular one...i used the strc aluminum upgrade link and have been satisfied with that, and i think the stock driveshafts have a little extension but youd have to really tinker with it to see how much more stretch you can get with whatever links w/o having to get new shafts, i still use the stock shafts with the strc's...alot of people i've found are able to make their own custom links with just the right tube and threaded rods and ball ends, and you'd be able to get the perfect length if thats something you can do, lots of threads on that here too.... hope that helps!

 

[notcrawlin]

thanx but..

thanx but i was also refering to the driveshafts that run paralelle to the lower and upper suspension links, do i need to get a certain length to work with the extended lower links. without using integey parts which links can i extend without needing to extend the drive shafts im talking about , the ones that connect to the bevel gears then to the tranny, maybe they r called slide shafts ,i dunno.

 

[inebriatedmarmoset]

yeah i know what you mean and they are the "slider style" driveshafts.....though i do apologize since i'm still new/learning myself, but yeah im not certain of what's available that's out there to just purchase that would extend your wheelbase for more stability without having to consider extending your driveshafts...

the ones i have now are strc's:

http://www.stormerhobbies.com/cgi-bin/seekpart.pl?pn=STRST85263S

and with the crawler king that i have, these i think are close to what came stock wth the CK which made the wheelbase extended by 2 1/4" and i think also came stock with extended driveshafts as compared to the WK since HPI also has this conversion kit for the WK:

http://www.hpiracing.com/products/en/87633/

i think, when they released the CK, it included alot of the parts in that kit, to provide for more stability needed for crawling

the bent links I was looking at are these:

http://www.teamstrc.com/index.php?route=product/product&path=50_8&product_id=116

which would probably be longer that what's on the stock WK

so there are some options that i've found, and i think it's "recommended" to upgrade/extend your driveshafts that come stock with the WK if you extend the wheelbase with new links, but if it works then it works from my experience, just need to keep an eye out for anything that may be damaging parts...so like i said you'll have to see what fits and how it performs, unless you can make you're own custom links to determine how long you can extend them w/o having to worry about extending the central sliding driveshafts...or getting an entire kit....hope that helps!
