New 1/8 brushless concept buggy , belt driven
 
Seen in RC Mag and posted on Neo buggy a concept 1/8 brushless buggy with belt drive , rear steer and central battery.

Looks interesting , don't know how it will go on a track being belt driven and having reer steer and no one knows which company released the info but some ones imagination has been working overtime.

Thoughts guys :neutral:

Looks different for sure, way out of the norm for a buggy. I have a belt drive 10th scale and I am not that fond of it at all. ( it is my Daughter's actually) Although I am always up for something new to try and buy...:whistle:..

magman 10.24.2008 09:24 PM

The 4 wheel steering looks interesting...although, how would it do on a track, that is the million dollar ques.

gtxracer 10.24.2008 09:28 PM

Very interesting. That 4 wheel steer should make things very tricky yet good on the track!

I agree...the 4 wheel steer could be a hindrance on rutted tracks...easily catching an edge where the regular buggy would slide a bit more.

gtxracer 10.24.2008 09:34 PM

That and there's a lot more parts to break!

Very true...and I also wonder if a belt would really hold up to the torque of brush less power

DRIFT_BUGGY 10.24.2008 09:40 PM

I wouldn't want a belt driven 1/8 buggy. One of the reasons why I sold my XXX-4 G+ for a BJ4

BL_RV0 10.24.2008 09:40 PM

Cool, but why a Quark?

DRIFT_BUGGY 10.24.2008 09:42 PM

lol, look big and long the belt is. Probably cost $60 everytime a stick/rock gets in

My daughter has a xxx-4G and it took me awhile to get the tension just right and then the rear diff cracked and broke which tore the belt to shreds. This car is the last belt driven I will ever own.

Yeah, I was running a Novak SS5800 in mine and had terrible trouble with it. Bought a BJ4 and sold the Novak system and got a Mamba 690KV, never looked back. Like comparing paper and steel

Similar to the old Kyosho Gallop for you older guys out there , prob nearly 20 years ago .
It had 4ws but used a chain for 4wd , now it's a vintage collectors car .

One of my first kit RC cars was a Kyosho Javelin that was an electric 4WD buggy and it was chain driven also. You might remember the orange plastic roll cage? Cool car, but the chain was a pain to keep the correct tension also. Wish I had it now though....it might be worth something on ebay!

lincpimp 10.25.2008 01:47 AM

Addl complexity, and it has to have more drag/resistance than a shaft buggy. I have owned a few belt cars and have no idea why anyone other than a carpet indoor racer would want one. Too much to go wrong, and they always seem flimsy to me...

MetalMan 10.25.2008 02:03 AM

I think a belt-drive 1/8 buggy would be cool. As for the flimsy-ness of belts, the solution is to go with a stronger one :yes:. Some day in the future I would totally want to make a belt-drive 1/8 buggy, but it would be custom made so I could play around with different belt widths, pitches, and materials.

Heck I just thought about converting our normal ring gear bevel diffs into suitable belt-driven bevel diffs: just machine an adapter (like that adapter that would allow the old plastic Ofna 51t spur gear to fit on other diffs), and mount a machined pulley to it. Everything else would be cake.

That is why man invented covers. :mdr: ALL of the belts have covers on them. That's my second favorite design aspect- next to the belt drive itself. The 4WS would be third. :tongue: Speaking of which the 4WS could easily be disabled by locking the rear bellcrank in place.

I've already decided I'm going to buy one of these. I've already started saving the $1000+ I'll need for the kit. :oh:

XXX-4 had covers which was pretty pointless

Well the entire point of a cover is to keep things out. So if they didn't work then they were pointless! :lol: I can see now where your disdain for belt driven RC's comes from. Personally, I like the silence. No more "rattling dogbones" with slotted BL motors.....

Patrick 10.25.2008 04:34 AM

I've never really like the idea of belts, though I haven't owned a belt driven car to say for sure which is better.
I like the idea of having all the weight in the centre, but it looks like it won't be able to have a centre diff, which means it probably won't be something I'd consider getting.

Well your not missing out on much, just extra maintaince

If that's the case then it's something I don't mind missing out on.

rootar 10.25.2008 11:47 AM

goota give who ever did it credit, they are trying to get out of the normal, it looks to have PERFECT balance, look at how LOW the whole car looks even the wing, it looks like itd be glued to the track................ and if the rear steering was ditched, and a strong enough belt system made with a good sealed housing (not that hard, make it like an atv's) with a slipper clutch.

and as for not having a center diff, 1/10thscale 4wds dont have a center diff and they EASLIY run just as fast on most all tracks as any center diff equiped 1/8thscale buggy can. NOW we obviously wouldnt want the ball diffs and do as someone else already said and have a belt spur made to fit the 1/8th scale diffs all ready out.

i think its an EXCELLENT idea and concept, it just has some obvious things that need simplfied.

One option is to throw a one-way somewhere between the motor and front diff. It wouldn't be as good as a center diff, but close (could install a neat mechanical brake setup on the front and get front/rear braking bias).

BTW, a "belt spur" is called a pulley :lol:

BlackedOutREVO 10.25.2008 12:28 PM

I dont agree with anything you guys say. Your all to attached to gear diffs

I run my cyclone (10th TC) On anything from parking lot bumpy ass rocky tracks, to Speed world race way, a permanent race facility since 99', to carpet indoors

And I have gone as far as a mamba max 5700 with a 3s lipo out font of my house smoking the rubber tires. I NEVER had to buy a new belt once. I raced 10.5, and 13.5, occasionally MOD, all with lipo batts.

The losi belt cars blow nads, but just because one car is junk, doesnt mean they all are, the losi has 1 belt, and that makes using everything on the car hard as hell.

And I have my Mugen MTX4R, the thing has 3 belts, 2 F/R belts, and a side belt, never had a rock stuck in it from out front of my house, to the track, or never had a jacked up drive train. The drive train in the Cyclone, and Mugen is smooth as heck, it will free spin just fine.

I know if the guy designed that buggy right it would work way better then a normal buggy would, its the people like you guys who wont give it a try is the reason the stuff like this isnt coming out

I dont mean to offend anyone, so do take it like that. Just trying to get my say in

jhautz 10.25.2008 12:58 PM

Belts could be done as long as they can be protected from the stones and stuff. I mean if they can drive motorcycles and snowmobiles and stuff on them why couldn't it be done well in a 1/8 scale?

It would take some development, to make it robust, but I think its possible. It would need a way to diff the center like the current systems to handle well so thats a challenge.

Not sure about that 4 wheel steering thing.... Whats the point, its not a crawler. Seems silly to me. In real cars that have attempted 4 wheel steering it is pretty much only active at low speeds because at high speeds it creates instability.

Romster 10.26.2008 08:53 AM

I bet it would be real hard to keep it straight going down the straight away.
It would probably be real twitchy.

i had a brain fart the other day :wink:

and i agree with blackedoutrevo, there are plenty of tough belt cars already made, they only need to beef it up a little to handle the extra weight and strain of 1/8th scale offroad racing and itd be fine. plus just think if your battery is sitting in the perefect middle you dont have to worry about how big of a battery you run so much like we do now for balance, i mean you could run a 6s 5000 battery in the buggy with a 1500-1700 kv motor and we could easily run 30 minute mains with NO stops :yes:, also the chassis could be very narrow since everything sits on the center......

plus to help keep dirt out there wouldnt need to be any holes in the bottom of the chassis and the mud guards could wrap all the way around to the diff housing in the rear and use velcro for the body thus helping keep most all of teh dirt out.

lutach 10.26.2008 10:26 AM

I could make one work. The problem I see with this concept this guy have, is that have made it too complex. The most effective set ups out there are the most simple. I'll start cooking up some drawing and if time allows, I'll make one. Might be a waste of time, but if it works it should look cool.
