Anyone thought of takin a truggy, stretching it and making it a 5th scale?
 

Just an idea I had...something different. I know that you can buy a 1/7 and 1/5 scale but, one based on a truggy may be cool? Stretch the chassis 2.5 ", have custom length center driveshafts made and done!:intello:

Put 8s in it w/Lutach's 10s esc and a 1521 and see what happens:whistle:

2.5" to go from 1/8 to 1/5 scale? Might need more than that I would've thought.

The theory is sound though- just take a look at Candyman's latest build- custom chassis and centerdiff unit with truggy/buggy front and rear ends. Use some offset wheels and/or axle extensions and hey-presto. :yes:

Something similar was emaxx baja and the emaxx road car...

Man it seems like you streach everything!

all yours linc...

Start with a XTM MMT. Longest whelbase of ANY MT and all it is, is a big Truggy.

I did this with my e-maxx. http://www.rc-monster.com/forum/showthread.php?t=10363

I like to be different!:mdr:

I looked at your thread last night....very nice!

My thoughts exactly...I actualy did not measure, so the 2.5" was a guess:yes:


My old 2.5 maxx I just sold was going to be converted into a road car. I though about adding the Monoblock chassis ext. from UE to make it really long

i think it would be a very cool project

I have always loved the larger scale rc's...not their price tag though. For minimal costs...new center drive shafts, wheel extenders, a homemade chassis by me, a new body and mounts, it should be relatively inexpensive conversion as conversions go.

I would not be adding that much weight...just the extra 2-3" or so of AL chassis, which I would have milled out, and the weight of the new shafts, so lets say 6-8s w/a 10s controller would do nicely.

Anyone got at truggy they want to donate....just kidding. I must finish my Revo conversion 1st.

Could someone tell me for sh*** and giggles how long their center drive shafts are in their truggy...it does not matter what brand. I am just curious


THANKS!

I used a 1/5 scale chassis and emaxx front/tranny/rear clips. Put on dual 7XL on 4S. Topped it off with a FG rally body.

Email Bill@rcalloy.com for custom shafts. He made 7 inch shafts for my application.

I think converting a truggy is a perfect idea. I even bought a Pajero 1/5 scale Dakar body for just such a conversion. The Pajero would have a smaller wheel base, so you would not have to use two custom shats, you can keep the stock rear shaft and just get a custome front one.

Good luck.

I wonder if Bill could make me a longer front shaft too... :wink:

He probably could, you have to be careful though...he said anything longer than 7 inches could SNAP.:wink:

I am guessing that is a risk Neil is willing to take :whistle:

Small correction to Bill's email.

Bill@rcalloys.com

Its not a 5th scale unless its atleast 27in long in my opinion. Thats what most base 5th scales are without the measurement of the bumpers. My FSR 1/5 MT was 32in and they concidered it a 5th scale. All depends on the person really.

I am looking at trying to go to 27-29" w/this idea. We shall see. It would be a fall project in any event.

The more I contemplate the idea, the more I am warming up to the idea of doing this:yes:

You should take a look into FS-Racing. Their stuff is cheap and In my opinion its quality.

Chassis I plan to use "chassis came with my 1/5 FSR mt", "solid as a rock"- http://www.fsracingusa.com/fs112125chassis.aspx

F-150 1/5 Body I plan to use "already have one but need another"- http://www.oversizerc.com/p/452928/f...l---black.html


The chassis I linked gives you plenty of room to move the front and rear assemblies back and forth to compensate with the wheelwell alignments. My 1/5 FSR MT was 32.5in long with a short bumper with that chassis and it wasnt even stretched along the chassis as long as it could be.
I would also like to get another set of rear and front center dogbones and cups. Their extremely reliable and their hardened steel.

Thanks for the link....it looks like the F&R ends will bolt right up. Maybe even the center.. I enjoyed making my own chassis before, but, with this one already done.....I may skip that part all together.

Interesting idea taking a truggy as base for a 1:5th scale. I quickly fitted two truggy chassis plates together. Mounted half offset crimefighter truggy tires to extend width and took some measurements to compare them with popular 1:5 scale cars.

This is about the maximum length i got with 2 chassis plates: Wheelbase 700mm / 27.56 inches. Width 430mm / 16.54 inches. Obviously too long.
http://www.rc-monster.com/forum/atta...1&d=1237508134

I then reduced wheelbase to baja 5 length: 570mm / 22.44 inches.
http://www.rc-monster.com/forum/atta...6&d=1237508134

Compared to a baja it is still too narrow. Baja: 460/480mm opposed to 430mm. This can be corrected somewhat with wider wheel hubs. Truggy wheels (145mm) are smaller in diameter than 1:5 scale baja tires (170mm). To be able to use 1:5 scale tires would probably require custom made wheel hubs. The chassis would need a top deck to strenghten it and might need to be narrower to fit a baja body. At least one custom center cvd is required ... cutting an original one in two halves and lengthen it with a metal tube should be an option either. Shocks would have to be adapted to carry more load.

All in all i would say it can be done. Having this much space on a chassis to fit batteries is almost a dream come true. Wheight will most certainly exceed somewhat the weight of a Savage Flux which leads me to believe one might even have enough power with a Neu 1515 (around 3KW peak).

In all actuality it may end up a little short of the 1/5 scale I want, however, we shall see

Thanks for your comparison

Where could I get wheel extenders to use w/truggy wheels

Mugen MBX5T uses extended wheel hubs or look for King Headz Wheel Hubs +12.7mm.

very interesting, im curious to soo who goes through with this and how it drives.

Thanks...I was thinking of using a mbx-5T as a base vehicle seeing as I have a mbx-5 and love it.

I will need toget the biggest shocks that will fit in it to help as well as some chassis braces to make it stiiff enough

You could use half offset truggy tires to increase width even further. A friend of mine drives an MBX5T which is as wide with standard offset tires as my Mantis truggy fitted with half offset tires.

I'll build one once CC puts out their 8-12 cell controller.

The 1/5 scale that I made from emaxx parts I ended up using two 7XL and two ESC. I like the idea of a single motor.

Good luck mag.

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

http://www.rccrawler.com/forum/showp...0&postcount=84

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.
