Radio Shack Motor Upgrades

[OneFastDC5]

Is the Gen 1 Stage 2 kit even worth picking up, or should i go straight to an aftermarket motor for an upgrade?

[nitemeer]

aftermarket for sure.. but if you want the gears.. then i guess you can buy that then go with after market motors.. right now i'm using Radline motors..

[SUPERSHELBY]

aftermarket motor FTW! depends on your stye of driving though.

[merc3des]

Yea the Speedy series is much better then a stage two. My store carries them. We do not carry pinions though =/ sorry

[wadethejuggalo]

i would go with the after market or have someone on the site make you a motor

[merc3des]

Yea there is plenty of fantastic motor builders around here.

[biggie862005]

how would one go about having a motor built, and about how much would it run me?

[XMDrifter]

check the b/s/t and the approved vendors sections

[ppericfe]

any website to buy Some nice motor

[kendallcschm]

after market all the way... personally i would go with a 180 motor... or this:

Hi all,

I lost track of which thread I posted this question but I think it is appropriate in this thread:

With all the focus on hopping up an XMOD for speed, isn't it really overkill to do more than use the RS motor upgrade for circuit racing/drifting? I mean, don't you just end up slamming into the guard rails on a closed circuit track? I can see drag racing, but how much control does a driver have on a closed circuit with these powerful upgrades?

Thanks,

--Doc

ok dude.. put in a sweet over powered motor and drive around turns at half throttle but if you hit a strait away go full throttle and pass the competition.. so a fast and powerful motor can be good for most applications.... but i am a drag racer.. so the more powerful the better.. but to answer your question no... you'll never know the track you might wind up racing on.. maybe the person has alot of strait aways on their track then you will need a powerful motor to pass them.. so enjoy :-)

Hey everyone,

I lost track of the thread I posted this question, but I think it's appropriate here:

With all the focus on faster XMODs, I've been wondering if there is a "breaking point"...with regards to circuit racing/drifting. At what point does power increase to the point where the car is just slamming into guard rails on every corner in a circuit race?

Isn't the RS Stage 2 upgrade enough speed for a circuit race with a reasonable amount of sharp turns?

Thanks,

--Doc

^That's what I would think.

[Doc Moddin']

Thanks, Kendall.

I see where you're coming from. I think my main concern stems from an Atomicmods advertising video where a suped-up XMOD taps an orange pylon, flips onto its hood, and skids for what looks like a few yards on asphalt.

Maybe I'm beating a dead horse, but it seems like an XMOD with AWD, bearing upgrade, and Stage 2 motor upgrade on Hi Throttle could keep up with a super tricked out XMOD on a circuit racing course with a moderate amount of straight-aways.

But I have to admit, I think the upgrades are really cool because they have taught me quite a bit about electronics and electrical engineering. College physics was quite a few years ago--I don't eveny recall how a brushless motor works, let alone why it out performs a motor with brushes.

No way. A modded xmod with as little as a lipoly upgrade will outperform a shack'd up xmod easily. There is a very big difference. After my lipoly upgrade, I can't go back to a stock xmod. Its just too slow.
Brushless I'm guessing means the motor lacks brushes resulting in less friction?

[Doc Moddin']

Thanks for the input, RSX.

I see what you mean, but when you approach a corner as fast as a Li-Po goes, doesn't it loose traction and slam into the guardrail? It just seems that human response time is inadequate to negotiate a corner going that fast. If I could learn to drift a corner at those speeds and miss the guard rails, then heck yeah, I want to do some aftermarket modding! But maybe this is a bit of "sour grapes" on my part as I don't have the cash right now to do that kind of modding. And from what I've heard about Li-Po, they take anal-retentive levels of attention to make sure they aren't over-charged, but especially not undercharged.

And my thoughts about tackling a corner with skill instead of muscle raises a second question: do the suspension upgrades really make a difference? Do they really help the car handle the corners better? Do the different spring tensions on those little springs really make the cars handle that much differently?

Thanks guys. BTW, if this is sounding like I'm ****in' in your cheerios, then my bad and I apologize. I'm a noob and just trying to get a handle on these mods.

I have a car with AWD, lipoly, suspension, bearings, stage 2 motor (with middle gearing) and it handles decently well. On a track surface it's still a bit difficult to just slide out of a corner, providing you have glued and sticky tires.

Suspension does make a difference. You look at the weight of a modded xmod with all that stuff compared to stock, specially with a new chassis, and you'll see how the stock suspension acts as compared to the stiff one. There's loss of power due to binding and such with a suspension that's too soft. Plus with the suspension you can set to toe-in which is great for faster cars that need to turn.

[XMDrifter]

yes they do. simple physics. the suspension parts do have an effect on handling. stiffer will keep the car from shifting weight as much, but a downside is that if you have too much grip, it'll start picking up the inside wheels off the ground, most likely causing traction roll.
softer will let more weight transfer take place while keeping the wheels on the ground under high grip situations.

human response time is, rather slow... i believe that using the normal AAA sized batteries is the best solution, whether they're lithium chemistry or regular rechargeable because it will retain low CG, which is the most important aspect of a micro sized racer.

[Doc Moddin']

Wow, great advice all around.

I'd do a MOSFET, except for two reasons:

1. My soldering skills leave alot to be desired, and I'm afraid of frying the PCB.

2. Sending my car out to be modded for me feels like cheating...If I can't do it myself, I don't want to "Win the science fair by letting dad do my science project for me." If you know what I mean.

My 2009 Corvette Z06 has the AWD upgrade for now...when I get the scratch, I'll get the bearing upgrade, suspension upgrade, and maybe the Stage 2 Motor upgrade. Who knows? maybe some day I'll work up the courage to try more advanced modding. Just not yet.
