Dual .21 Touring Car *ARMAGEDDON* - Page 5

in europe they race 8th scale touring cars with what i would call a 8th scale wheel and tire that resembles 5th scale wheels and tire(only smaller) would make a good choice

I should be sending out the template for the carbon fiber chassis VERY SOON. Im waiting for a payment from a friend, and then Im buyign a servo off the guy that is making my carbon fiber chassis, so when I send money, Im sending the template, and the shock tower templates. I got the frotn bulkheads finished today and mounted, so my suspension is basically done. I am also ordering the parts for my drivetrain setup ( gears, gear hubs, ect...) I am having problems with my digicam (card error) so I wont be able to get some pictures till probelly later this week. If anyone has a set of 1/8 scale buggy rims, or rims and tires they would like to get rid of for cheap to help me with this project, that would be great.

Thanks,
Joe

I got my gearhub for the center spur setup that I plan on usin today. I also got 2 gears for the set up. I will get some pictures later.

CrazyPhantom · #**104** 02-26-2005, 12:42 PM

Ok, I got some pictures of the gear hub. This will be the set up I will be using.

CrazyPhantom · #**105** 03-03-2005, 10:23 PM

here is a CAD drawing of the project done by another member on this site.

it isant done, but this is as much as he has gotten done so far, it looks so sweet.

hey guys had an idea i like the two motors but the idea of 2 onto a single spur isnt so good so i was thinking 2 differnt spurs with diff ratio's maybe a 2 speed box but the idea is u have duel throttle control and idle one motor up to say 90mph then the other lower geard motor takes over to 180mphor some thing like that the requirement would be its shaft drive and ud need to ad weight to ofset the staggerd engine desingn just my 2c so pm me with ur comments please

Soooo whats going on with this project?? Have you pieced it together, ran it at all? I think your design is great, so lets hear some news!

These 1/8 on road tyres are built by medial pro & are meant for buggies. They are moulded as-one piece-, so i guess ballooning would not occur.

"Tarmac II 25, 35, 45, 60 shore 1/8th Rally IAS Tires Pre-glued
From the same great minds at Medial Pro that brought you the phenomenally popular I.A.S. 1/10th scale sedan tire, now bring you the Tarmac II I.A.S. 1/8th scale buggy tire. Now all you off-road warriors can wreak havoc on-road as well. The Tarmac II features the patented I.A.S. (Integrated Air Support) technology which means the tire and insert are one molded piece. The result is a very flat and true tire with very little distortion under load. The Tarmac II comes pre-mounted in 25, 35, 45, and 60 shore compounds. These tires are a big hit on the pavement and rally courses. Check out Medial Pro's Rally Tire chart for shore to surface applications.

I got some of those on orders for my GT those are susposed to be some bada**ed tires ..

mook · #**111** 06-05-2005, 10:46 AM

yup they are excellent wheels. The soft compounds can burn out real quick, so my next order will be for 65 shore 'hard' compound. Once the tyres are warmed up, they are super sticky.

These should not balloon at all.

Hey, guys, I totally forgot about this post on this forum. This project has been moving very slow lately. To post an update, I just ordered a HPI R40 2 speed. I got it off ebay, and should be in the mail soon. I just graduated so I should be getting a bunch of updates on this project due to money gains. 2 weeks from now I should be getting my titanium chassis, and my either titanium shock towers, or carbon fiber shock towers machine ( or aluminum ). Besides that, there isant much new with this project, I will try to keep you guys updated on this project since it should start to move along again.I know for sure I wont make the r/c challenge, But Im still going to try to break Cliff Letts record so I know mentally i did it. I am trying to get the chassis set up for now, and the whole drivetrain set up, then Im goingto order either foam buggy wheels, or rubber buggy wheels. Here is the 2 speed i just bought. Let me know what you think.

CrazyPhantom · #**113** 06-15-2005, 05:41 PM

I got my 2 speed in the mail today, so I will get some pictures later

dynamite25 · #**114** 07-02-2005, 05:51 PM

Hi for you car why don't you use two of these engines

as i am using two for my car that i am building soon,the enigne produces 2.7hp and revs to 38,000 rpm.

cool head · #**115** 07-02-2005, 06:10 PM

unfortunatly hyper engines aren't known for having much bottom end to them. their kinda guttless under 30k rpm. so those engines probably wont have enough grunt past the shift point.

dynamite25 · #**116** 07-02-2005, 06:27 PM

So what would be a better engine as i will be using a two speed in my car that i am building which is based on this car Radical SR8 sportscar and is 1/5 scale .

cool head · #**117** 07-02-2005, 10:38 PM

if it were my call i would not run small nitro engines in that rig. i would modify an exsisting G23 to run on nitro. you can probably get 10-15 hp out of one. that should be plenty enough to push it into triple digits with the right gearing, pipe, tires ect. the problem with running 2 little nitro engines is the tuning nightmare. i'm a good tuner and i couldn't get them perfect under speed run conditions.

dynamite25 · #**118** 07-03-2005, 08:12 AM

I think i might be best to use a FG Zenoah engine G23 i think i can get one for £330 and how much would it cost to convert it to nitro,the car will be running on FG 1/5 wheels with slick tyres.But could it be done if the .21 engines were tune right as i am pretty good at tuning my engines for top performance but still make them last along time.

Also here is a side drawing of a Radical SR3 to show how big the car will behttp://img.photobucket.com/albums/v2...sr3outline.jpg

cool head · #**119** 07-03-2005, 09:52 AM

there are kits availablee to do the conversion that include aky carb and glow plug adapter. there are a lot of mods you can do to get a lot more out of the G23. but the best option for your aplication is gonna be NOS on top of the nitro conversion. that will truly bouble your HP and best of all, you'll have the torque of the large displacement G23. most of the good info you will need will be in boat and go-ped sites

dynamite25 · #**120** 07-03-2005, 10:27 AM

Now that i have started the drawings for the chassis i don't think a G23 engine will fit in behind the rollbar because i only have 150mm between the rear axle and the rollbar to fit a engine in.

CrazyPhantom · #**121** 10-24-2005, 11:21 PM

UPDATE!

Well, not too much happening on this project, I got an erge yesterday to start basically redesigning this project, I have decided not to go with chopped up parts to just get away with things, now that the speedchallenge didnt happen, I have plenty of time. I have redesigned most (if not all) the parts, and I will be getting custom bulkheads(aluminum), shocktowers(carbonfiber),chassis(titanium),top chassis(aluminum),giga crusher 3 speed tranny, v-angle custom twin motor mount(aluminum),custom driveshafts(aluminum),

This is my basic plan for this project.
Got most of it designed up on CAD.

here is the bulkhead(doesn't include the hole wher the diff will go through) This bulkhead I custom designed to allow the a-arm to be incorperated into the bulkhead. This will bring the a-arms in and clean up the design of the project a great amount.

Kyosho 3 Speed on the way to my house!

fasterthanspeed · #**123** 02-07-2006, 01:56 AM

you should probably run 2wd.(just my opinion)

Kyosho 3 Speed on the way to my house!

Im installing a three speed into a landmax (mp 7.5). The first person to do this to a lm2 (evilgearhead) clocked his car at 74mph using a kyosho gs21r engine. He also said it was still pulling but had to stop as he was running out of space.

you should go warp speed with a twin engine setup!

Heres a pic of my nearly completed landmax three speed.

What is the diameter, width, and hex nut size of the medial pro tarmac 2?
