Here is a couple of thoughts for you.

I was looking at buying a Kyosho ST-R Truggy to convert. I asked the guy selling it to give me the width and he told jsut about 17.5 inches.

Due to the size of the wheels on a truggy, you will probably need to do a "scaled" look. If you use the Ford 150 body (very narrow) the wheels will be sticking out yet will not have a "monster truck" look because they would be scale look in size.

Most sedan bodies (for a rally look) are 15.5 inches in width, the Pajero body is 16 inches (perfect size for a emaxx conversion), and only the very large MCD Hummer body is 17 inches wide (still not 17.5).

The problem with the Hummer is that it is VERY large and long (I have one), so it will require very large shafts that will not stand up to the power needed to move such a large vehicle.

I can probably take some pics if that helps out.

Your best bet is to after a "buggy" look and use the FG or Baja buggy body.

Good luck.

A project like this could really take off when hpi releases the savage 5t parts, then u can get ur hands on some 24mm wheel hubs, also New Era has a chevy pickup body for their H4x4 conversion which is 5th scale.

Hey guys
I was searching for info on this subject
here is my project in progress, 1/5 Rally All4wd stretched emaxx
7.5" center driveshafts
20.5 wheel base
16 wide
33 long

Feigao xl motor
temporary Mambamax
58 Spur 21 pinion 32 pitch

12 cell 4500 Nimh or my 11.1 3S lipo 2250

Locked diffs
All 4 Tires Burnout and has lots of torque up to 10mph
estimate 25mph top speed

I'm trying to decide what battery and esc ???
6S batt? or what 8S battery ?

Any ideas
Thanks

See my build link below for more pics

Looks great speed assault.

MMM, 4s lipo (2x 2) for use with ~2000kv lipo, 6s (2x 3s) for ~1600kv. Assuming you are after ~40mph topspeed.

If you are after maximum topspeed possible, the MMM motor would be good on 6s lipo, but a feigao XL motor in the ~2700kv range would make it fly on 4-6s lipo too (speed runs only). Lots of possible setups, depends on your budget and ultimate aim really...

Hey Thank u suicideneil
to clarify- the higher the Kv the more torque ??
I still have yet to figure out what continuous amperage and burst to use-What battery, how to decide ?

The temp Feigao motor is 2383 kv
I built mostly because I lost my job and needed another build.
The build was mostly from spare parts
BUt now I have a Product "Forword Twin stick" to bring to the market for the Toyota Dual transfer case trucks and sell.
When I start making some money and sell some auto trannies I be able to buy some power.
When I get my normal Job back (Network Administrator) I will be able to afford what ever ! 8S 10S Lipo, MGM ESC, Neu 1512 motor , and so on
I figure for now buy a MMM and two 3s lipo's

I want 60mph

It's a blast to drive, especially on slick asphalt :mdr:

Nay.

More kv just means more speed on the same voltage- torque depends more on gearing than anything with the motors we generally use, there are numerous threads on the subject and how to calculate it, but its awfully confusing- any large XL sized motor will be powerful enough, but 4 pole motors like neus and medusas will be better than feigaos.

Battery choice isnt that difficult, assuming you have room for them. Just look for something that can provide at least 100amps of current, or more like 120amps to give you some head room. You can do a bit of fun maths though- take the rated wattage of the motor, divide it by the voltage of the lipos you plan to run, and that will tell you how many amps you need roughly as a continuous rating; peak current draw is a bit more difficult to determine, but some motors list the peak wattage, so that makes it easier.

25-35c 5000mah lipos are a good base line to look for.

MMM and 2x 3s lipo will be plenty for 60mph, look on rclipos.com for your batts if you want top quality, or hobbycity.com & look at the Zippy lipos (blue bricks) for best bang for bucl lipos.

its not a truggy, but this guy converted his emaxx to 1/5 scale
with videos as well

I cant even look at that traxxas thread, I could feel my IQ slipping with every post I read...

The principle is fine though- assuming the longer chassis doesnt add more than about a 1/4- 1/2 lb in weight, then the same electronics and what-not will work just fine in a stretched version of any given vehicle, just gotta tune it to suit the different balance and handling etc.
