xmod purchase + set up advice

[ezenterprises]

Ok, well its been a LONG time since i was into micro rc.... many things have changed or been added. Theres many upgrades now and aftermarket parts. There is a new "club" in my area, and they are starting to have regular races about every 2 weeks. So i am wanting to get back into these. The 3 classes are 1) stock xmod 2) xmod with official xmod mods 3) open class xmods with any mods.

The track is the official RCP track from the official xmod races that RS held. This is the info i got, i have no clue what this is made of or the layout. ( will find out saturday at my first race ) and it is also timed with AMBrc timing, which i have no clue what that is either but i was told that there is a transopnder that plugs into the headlight or something for the timing.

So, my question is..... driving skills aside..... What do i need to smoke this joint? Ive heard about all this alloy and carbon stuff and a little thing about this rapper NELLY ( lol j/k ) but what exactly is there and what do i need? For the open class..... that is...

Obviously stock is stock and rs mods are pretty limited ( unless theres new stuff since i was into these ) so i want to race in the open class.

And i know there is alot here on the forums, but if ya dont mind , i'd like to get it spoon fed to me. THANKS

Thanks for all the advice in advance.

Visit this site and learn about the Whoa Nelly and the Palsmatomic motor.

It's ph2t's site.

http://www.woahnelly.com/

There is a lot of info on the turbo that he makes and the motor that he recommends. If you put both of them together, you'll have a killer set-up.

Plus, there is also the Iwaver board swap too. You put an Iwaver PCB in your Xmod with the turbo and motor and it will dominate for sure.

You could alwalys fet stack an Xmod too, but thats old news.

Pick up some bearings from this guy on Ebay, they are cheaper and better than RS's bearings...

http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... 31553&rd=1

Make sure to check all his auctions, sometimes he lets some slip thru really cheap.

There are a few other little things to look into, but those are the biggies, I'd say.






P.S. Did you ever get your bit controllers? PM me with the specific freqs you need. If you didn't.

How big is the RCP track and the length of the strait-a-ways?

SG's got some good starts but don't forget to check out my site for the GPM. If you get the hotter motor you will break the stock plastic axles and ball cups.


Since the first race on the track you might be bouncing off the guard rails be shure you bounce off into the lead car.

Well i havent actually seen the track but was told it is the same one used at th epromo races by the shack. Now this coul djust mean same type/brand and not the same layout.... i dont know........ will see track saturday. However he did tell me the dimensions which i forgot but it was somewheres around 20 something long and like 10 or so wide ( feet that is ).

Now from what little i have read, im wanting a nelly turbo, and the plasmatomic motor. Now you mention shafts and cups...... what kind you recommend? any links?
Also i will be getting bearings..... should i get the "wide" set up ones i saw or just regular?
And what about the tighter turn mod? im thinkin that would be good.
Batts......... li-poly or li-ions? or are regular ones fine with the turbo and motor setup?

For electronics.. ive seen the i waver board swap. the nelly turbo and the v2 board or whatever from atomicmods and just stacked fet's..... do these all basically do the same thing? Which is best or which go together best if they are different?

What else should be lightened up or beefed up and maybe links to the stuff?

THANKS

Probabley two of these.


If that is the total size then I would not go Lion or any extra cells. I have raced on one of these tracks and what you need better than speed is handling. Which side are they using the Smooth or rough side? The smooth side will work with any tire but the rough side works best with the RS foam tires.

Now from what little i have read, im wanting a nelly turbo, and the plasmatomic motor. Now you mention shafts and cups...... what kind you recommend? any links?

GPM is a good value for the cups. I carry most of the rear end parts in my shop now. I'm just out of the rear ball axles.

Also to save on some weight either to the center axle mod (SG's) or replace that heavy steal with Titanium or carbon Fiber.

Also i will be getting bearings..... should i get the "wide" set up ones i saw or just regular?
And what about the tighter turn mod? im thinkin that would be good.

Get the bearings from were SG said to. The wide track help allot with the slop in the wheels.

The track will be wide enough that you may not need the tight turn mods but if you run a Nelly or other turbo I would recommend it for the fact that you will be entering the corners faster.

As for batteries Rayovac IC3 batteries are recommend. Lions give you more speed but on that track speed may just make you bounce off walls. I have ran wide open with IC3's and the stage 2 with the blue gear and didn't hit any walls. Another thing you would have to make sure your turbo will still provide 6 volts to the lights socket for the ABM Transponder if you want to be counted. Most of the Turbos with regulator will only provide 5 volts which may not be enough for the transponder to function properly.

For electronics.. ive seen the i waver board swap. the nelly turbo and the v2 board or whatever from atomicmods and just stacked fet's..... do these all basically do the same thing? Which is best or which go together best if they are different?

Pretty much but that differance is efficiency. The nelly will give you more power to the motor for the same power in compaired to the others. It will also runn cooler and still provide the break function you will need when you start running faster on that track.

What else should be lightened up or beefed up and maybe links to the stuff?

THANKS

I mentiond the drive shaft. Don't forget the front knuckles.

Wow thanx for all the great info..... another quick q..... 2wd or AWD?? And can you get all that gpm stuff in anodized blue?or chrome?

Also , if i go with a non rs motor upgrade, such as plasmatomic, i will then need an electric upgrade too?

[sg219]

I like the AWD for control an and overall performance and 2WD for straight on speed. I think AWD gives you the best use of all your components: turbo, alloy, mods, and whatever else you throw on you ride.

I currently don't have any blue and have a few things in chrome. But I can order those colors. Let me know what you want so I can put them on my next order.

As for the motor the stock electronics usually can't handle anything but the stock RS motors. With a 20 foot straight-a-way you want one that is a good mix of torque and speed.

Actully CJ i have ran a PNS03 on stock FET's and they only got warm, 4 AAA ofcourse.. And EZ i sent you a PM

[betty.k]

if you run a motor hotter than the st2's there's no guarantees, but ph2t ran a plasma dash in a stock setup without disaster. it's because there is a large heatsink in contact with the fets. it got pretty warm but no pop fizz like on a mini z.

definately go with awd, if you want a 2wd get an mr02. on the tarmac 1:10 racetrack i go to i cream miniz's in the corners because i can go hard on the throttle while they often spin out. this is the awd doin it's thang.

a mini z or iwaver pcb is a great addition, smooths out the control and offers more torque. but then you're limited by motors unless you upgrade the fets.

alloy must haves are rear cups and front knuckles. this will save you money in the long run.

[ezenterprises]

So even a pcb swap will not allow the hot motors then........ So im assuming my best bet would be a nelly turbo? And the only problem with that might be the transponder for the lapcounter????
Well tomorrow i will see the track and maybe get a feel for what will work there ( tho i wont have my car yet, might get to borrow one tho. ) Im thinkin prolly will stick with ic3's, wide bearings,AWD, some alloy stuff, maybe tight turn mod, stage 2 motor.... nuthin to fancy till i figure what the track will handle.... then maybe go for the nelly and the plasmatomic motor and /or li-ion/poly batts........

And cj, is the chrome gpm stuff "blingin shiny" or is it more silver/alloy colored?

[backdrift]

I belive the alloy is blingish

[ezenterprises]

got another Q...... i was pokin around on ebay and saw a "capacitor mod"...... any info on these? i tried the search function but didnt find anything.......

[sg219]

Instead of the 4??k on the stock RS motors, some people replace them with 103k. I think those are the right numbers. Anyway, it helps with interference when you do that.

[betty.k]

either that or a fet stack. and that's in the case of the iwaver pcb.

And the only problem with that might be the transponder for the lapcounter????

that's gonna be a headache. even with 1:18's the size of the transponder is a problem. there should be room, it's just gonna make it real top heavy.
