Q: I live in Timbuktu, how much
will shipping be?
A: Our international shipping
has recently changed. All international shipping to any country
will be a flat rate of $23USD (for 1 kit). Some restrictions apply depending on how rural the area you
live. All international orders are shipped with via USPS Global Express Mail
(EMS) with insurance and delivery confirmation. Items usually
arrive within 5-7 days of placing your order. Using EMS
costs a littler
more than using other methods, but we have never lost a package over
seas yet. It is the best shipping service we can provide.
PayPal will automatically add the appropriate shipping when you select
your country from the drop down menu. Contact us if you have
questions regarding shipping to your country. |

Q: What is the x3?
A: x3 is the latest in a series
of conversion kits that allows the use of any 540-sized motor to fit
into HPI's popular Micro RS4. There are 3 unique conversion kits
being offered, each of which specializes in the use of different kinds
of battery technologies. You choose the kit that best suits your
wants and needs. All of the kits incorporate many of the same
parts, so they can be interchanged with each other, including the
replaceable rear pod design introduced by the RS480 which offers 3
different kinds of tuning options for the ultimate experience in
performance, handling and speed. |
 |
|
Q: What comes with the each of the x3 series
kits?
A: Since all of our products
are only conversion kits, you will only receive the parts necessary to
make the conversion from a stock Micro RS4 to a 540-Micro RS4.
Check out the Part List for each of the kits to see exactly what is
included. A basic parts list far all kits consists of the carbon
fiber chassis pieces, the standoffs, and all the screws.

|
Q: What is the shock that I see in all the
pictures? Does that come with the kit? Where can I get
one?
A: The shock that we recommend
using is the VCS shock made by Team Associated. It does not come
with the kit. You can buy them for about $14 from places such as
Tower Hobbies. Also, you may want to try the Front RC18T
shocks since they will also fit the kit and cost somewhat less than
the VCS shock. |
|
|
Q: What stock Micro RS4 parts will I need to
use from my original Micro kit with the x3?
A: You will need all the
original Micro kit parts except for the chassis pieces and the parts that
get replaced by the required list of hop-ups shown below.
|
|
|
Q: What aftermarket hop-ups should I buy
to go along with the x3?
A: There are a few items that are required and a few items
that are just really nice to have. This is a list of required
aftermarket hop-ups:
Rear ball differential (HPI or Team Orion recommended)
Front ball diff or one-way differential
Aluminum, alloy or steel universal joints (dog bones)
Here is a list of really nice parts to have but aren't
required for basic operation of the kit:
HPI servo mount and dual-link tie rod set
VCS Micro Shock from Team Associated
Aluminum knuckles (steering blocks)
Antenna mount
|
 |
|
Q: Okay, I've got a stock Micro kit, with all
the sweet hop-ups listed above, what else will I need to get my x3
running?
A: You will need the following items:
Battery Pack - Lithium-Polymer, 4-cell Sub C, or
6-cell 4/5SC depending on your kit.
Battery charger - Make sure it charges the right type of pack you have.
Radio, receiver and standard ESC (1/10th scale type such as MC230CR,
GT7, etc.).
540 Motor - Please abide by the turn limit specified in your kit.
Various 48-pitch pinions ranging from 27T to 30T (smaller pinions
are recommended)
|
 |
|
Q: What batteries fit in each of the
different x3 conversions?
A:
Each kit in the new x3 Series kit offers the user the best battery
option that suits his/her needs. The Lithium-polymer 540i uses
both 2S and 3S battery packs. Check out the Lithium-polymer 540i
page for more details as to which packs fit the best. The 4-cell
540r uses regular sub C batteries, such as GP3300, IB3800's, etc. in a
3x1 saddle pack configuration. Please check out the 4-Cell 540r
page fore more details. The Gen2 540 Micro Hybrid uses 4/5 Sub-C
cells such as GP2200's and Sanyo CP-1700's. Please see the Gen2
Micro Hybrid page for more details. |
 |
|
Q: Where can I get the right batteries for my x3 conversion
kit?
A: Check out the
following online retailers:

We've bought from all of these guys and
they all offer great prices and exceptional service. |

|
Q: What bodies fit on each of the
x3conversions kits?
A: There are several bodies that comfortably fit
each of the kits. The bodies that best fit must be very wide and have a 150mm
wheelbase. The dimensions of each chassis as as follows:
Lithium-Polymer 540i = 100mm, 4-cell Sub C 540r is 98mm and the GEN2 Micro
Hybrid 540 is 103mm wide. Based on those dimensions, here are a few
bodies that will fit:
Proline Mazda6
Proline F360 Modena
Bolink Camaro
Bolink Mustang
Various other Bolink Bodies that are wide
RAD CLK-GTR
RAD Lambo SE
|
HPI Mercedes CLK
HPI Corvette C5-R
HPI Murcielago
Various BRP Bodies
HomeR 959C
HomeR GTR
HomeR New Body Coming Out |
This is not a complete list of compatible
bodies with the Micro Conversion Chassis. If you've got a body that
fits the conversion that isn't listed here, please drop us an email at support@aktionrc.com.

|
Q: How fast will this make my
Micro RS4 go?
A: Faster than you can even imagine. Depending on
the gearing and the type of motor you use, your Micro will be no slower
than 40 MPH. But you can easily see top speeds of 50+ MPH even with
stock motors and conservative gearing. But be prepared, because it
is very fast. |
 |
|
Q: I want to buy the kit, but
I'm worried about performing all the modifications. Is it really
that hard to do?
A: The instruction manual that comes with the kit is
very detailed lots of high-resolution pictures showing in-step
procedures for each modification. All the modifications can be
performed with only a drill, a piece of sandpaper and hobby file.
However other methods for performing the modifications is explained if you
have power tools (like a Dremel). Keep in mind though, the x3
series conversion kit is intended for advanced hobbyists with
significant knowledge with respect to electric RC. |
 |
|
Q: What is the best 540-sized
motor that you recommend?
A: Any standard 540-sized motor that has an open endbell
with replaceable brushes will fit any of the kits just fine.
Old-style stock motors with
closed endbells do not fit.
|
 |
|
Q: Is there turn limit for each of the
different x3 kits and if so what is it?
A: The Lithium-Polymer 540i has
a stock 27T motor limit with standard 24º
timing. The Gen2 Micro Hybrid 540 has a 14T limit, and
the 4-Cell Sub C 540r has no motor limit. Please be advised that
these motor limits are in place for the protection of your batteries
and your motor. Do not exceed these limits under any
circumstances. |
|
|
Q: Why is there a turn limit for each of
the kits? Isn't that something defined by the ESC?
A: The turn limit for each kit
is defined by the batteries that each kit uses. The
lithium-polymer cells that fit the 540i kit have a limited maximum
current discharge capability which can be exceed if a low-turn
modified motor is used. We have found that the current draw of
stock 27-turn motors is well within the current limits of some of the
best lithium-polymer packs which we recommend. You can
permanently damage your li-po battery pack if you exceed its rated
discharge capabilities. The same theory goes for the GEN2 Micro
Hybrid kit which uses 4/5Sub-C cells which have a rated discharge
capability of about 40A. Therefore we have put a 14-turn motor
limit on that kit again for the protection of the batteries. The
4-Cell Sub-C kit has no turn limit since the cells it uses are
designed to sustain very high current draws, over 60A without damage.
Also, since these cells are used in regular 1/10th and 1/12th scale RC
cars, any 540 motor they make for those, will work in this kit.
Ultimately, however, your ESC also limits how low a wind you can run.
Be sure your ESC is rated to handle the motor you wish to run. |
|
|
Q: What kind of ESC do I need?
A: Any ESC that works for 1/10th scale cars will work fine.
But remember that not all standard ESC's can run all motors. Check
the motor limit on the ESC and be sure to follow it. Micro-type
ESC's are NOT recommended. |
 |
|
Q: My question isn't answered here, where
else can I go for more help?
A: There are a number of great
1/18th scale forums which you can visit such as
one18th.com and
www.yourmicro.com.
Additionally you can stop by our very own forum at
www.aktionrc.com/forums
which is dedicated to 480 and 540 Micro owner from around the globe.
