ThunderbirdJunkie -> 1/8 GT? (4/20/2008 9:02:44 PM)

So my local club has started a class that I could easily (read: cheaply...for RC) get into called 1/8 GT. the cars are essentially 1/8 buggies converted for on-road use, and run .28s. I'd like to get into this class, and I'm thinking about grabbing an Ultra GTP (cost IS an object) for it, and running a bumpstart STS .28 (because I have one). Any thoughts on electronics? Since I just got a JR 9100 for my Savage, I figured I'd gank the old Airtronics 94162 from it and running it in said car. What about body options? Tires would probably be Panther's 1/8 slicks or GRP premounted hoops...but I'll find out what everybody else is running.

That being said...thanks for any input...and as many posts as I've made, I apologize in advance if a search would have helped. OOPS.

I just ran my ultra gtp dirt oval chassis and it's awsome! I would go with rtr as it has a 2 speed already, the roller has a single speed and is slow out of the box. I have an axial.28 in mine(cheap)and the clk body works pretty good, nothing to compare it to though. I like it a lot and am impressed with quality and durability so far. For 319 rtr or 189 rolling chassis, cant go wrong either way, just not sure if rtr is in stock anywhere yet. If going for roller, it comes with 2 extra 1/2 inch offset hexes for oval(4 standard ones already mounted). Also comes with 14 tooth pinion, which is way to slow, 18 tooth is much better.
Oh, I'm using jr 590zm for steering and some cheap 12$ servo for throttle/brakes and so far so good! Was worried about throttle servo being to weak at like 40 oz.in. but no worries so far.



ThunderbirdJunkie -> RE: 1/8 GT? (4/21/2008 2:50:54 AM)

Thanks! that's exactly what I wanted to hear. at $100 for the 2 speed and $50ish for the body, the RTR is what I was leaning toward, but I didn't know if the roller had any better parts that the RTR didn't. I've got a bunch of 25-28ci engines to throw in there, and I was thinking a Mach 427 or my STS would give me the RPMs I'd want.

I've also got a couple old no-name 1/8 buggies that I'm considering converting with Inferno GT parts, since they're the HiSpeed manufactured buggies that are compatible with lots of Kyosho 7.5 parts. Too many stinkin options!



CBM Racing -> RE: 1/8 GT? (4/21/2008 6:27:31 AM)

Oh, before I forget, the motor mount is pretty short on the roller. I was going to put in mach 427 but the spinstart was about a 1/4 inch to low hitting the chassis. If you have the bump start version, or a different pullstart to try it might fit, otherwise get the shims ready. I'm gonna try in morning to get either that in there or an lrp spec3, the axial just doesn't have the rpms I want. Also going to try 18 tooth bell, and then try some other options from the touring car clutchbell pile accumulating in corner. The axial is no super powerhouse, but it will roast tires at anything under 3/4 full speed so a good mill like the mach or sts should be crazy with decent gearing!



ferrarimk13 -> RE: 1/8 GT? (4/21/2008 4:27:20 PM)

the GTP is a great cheap car, but not as good or upgradeable as the Inferno GT. Both are good though, and if budget's your thing, then the Ofna is awesome, great customer service as well.



ThunderbirdJunkie -> RE: 1/8 GT? (4/22/2008 1:37:01 AM)

CBM, I've pretty much decided to go with the RTR...but I'll be running a bumpstart STS 28. Through some fluke a couple years ago, I also just happen to have bumpstart engine mounts for a HongNor 9.5:D Hopefully the stock gearing doesn't suck.

ferrari...the Kyosho is more than I want to spend for an RTR car I'm just going to rip all the guts out of...and they also have that goofy engine mount that I'd much rather not deal with. Now maybe if I got a screaming deal on a Kanai I II or III roller, I may decide to rock a green car:) Also, I've got a ton of cars on which I've spared no expense...so it'll be cool to compete on the cheap.



ferrarimk13 -> RE: 1/8 GT? (4/22/2008 7:19:32 PM)

you wouldneed to change a few things on the kanai, but on the end, that thing would be sweet lookin! new arms, shocks, wheels, and thats about it, and youll be ready to go.



ThunderbirdJunkie -> RE: 1/8 GT? (4/23/2008 1:12:27 AM)

When I looked up suspension arms for the Inferno GT on Amain hobbies' site, they came up as interchangable with the MP7.5...what's up with that?

the inferno gt is a 7.5 modded for onroad the only tru diffrence between both cars is the shock towers, the shocks, the front center dog bone on the GT is shorter, the inferno gt has the 2speed, and ofcourse the body and wheels, everything else is exactly the same even the main chassis the only diffrence is the inferno chassis has 2 extra holes in it for the 2speed

also everything from the WC777 buggy works on the 7.5 AND the inferno gt so any hop ups u see that spark ur interst for the WC777 can fit the inferno if u buy it



ferrarimk13 -> RE: 1/8 GT? (4/24/2008 12:10:53 AM)

yeah, thats what i like about it, i would bling it out with all the green and blue kanai parts, lol.



ThunderbirdJunkie -> RE: 1/8 GT? (4/24/2008 1:17:37 AM)

So assuming I scored a cheap 7.5, what would it run me to put the 2 speed in it? I'm not seeing anything come up on fleabay

yup ull jsut need to drill 2 extra holes in the chassis

ull need to drill the holes about 3-4 MM in front of the 2 holes the chassis already has where the center diff mounts

basicaly this is what the bottom of the MP7.5 will look like ull need to drill those 2 red holes i marked so the 2speed will fit





ThunderbirdJunkie -> RE: 1/8 GT? (4/24/2008 1:39:05 AM)

Easy enough. time for fleabay!

I'm sure a suitable K2 or K3 (or maybe a 777?) will pop up in the next week.

im sure it would but rember the 2speed for the inferno gt by itself is kinda expensive i think its about 70 or 80 bucks complete, and the shocks from the inferno gt are 30 dollars a pair, and the body is expensive too, besides that the rest of the stuff is el cheapo like the shock towers and bumper

in the end ull prolly spend about the same as the RTR inferno gt but since ur looking for something like a K2 or K3 ull have a much stronger car

also how much do u know about the Kania series buggys, are they a little TOO old??? r the parts compatable with the WC777?? i know the SP2 and SP3's are. Honestly with all the versions kyosho has come out with ive gotten a little confused i just know the 7.5,inferno gt, and WC777 like the back of my hand (and the truggy too)



ThunderbirdJunkie -> RE: 1/8 GT? (4/24/2008 2:05:52 AM)

the Kanais/MP7.5s are the last-generation before the 777...I'm open to other options as far as 1/8 buggies go, too. the shocks shouldn't be a problem...I'm a bargain hunter, and I know I can snag some dirt cheap shocks somewhere.

and the 2 speed for the Ultra GTP is $90 by itself, and the Ultra GTP RTR is $319...so I'm still keeping my options open. I don't have my mind 100% made up yet, but I have a good general direction on which way I want to go....but I'm pretty dang sure that if I started out with a Kanai I bought for $150-200, and put $200-250 into it to pound pavement, I'd still be ahead on buying an RTR Inferno GT because of the superior equipment, since I already have an engine/exhaust and radio gear to put into the car.

I'm also keeping my eye out for used GTPs, DM-Ones, and other 1/8 buggies. Wouldn't be too hard to cut the shock towers on another car and drill holes to mount shocks, and rig up some body mounts.

Until then, I suppose I have to settle for thrashing on my beat up old Savages[&:]



CBM Racing -> RE: 1/8 GT? (4/24/2008 3:39:23 AM)

Yeah, projects are a lot of fun when you have the time to tackle them. I was gonna go that way as well, but figured for the limited time I had I was further ahead to just get the roller and go from there. Glad I did, gets more fun everytime out when you don't have to find the perfect setup, tires, gearing...etc. This is my onroad/light offroad fun car and like you say, keeping costs down and fun factor high is main goal[:D]. Whatever you opt for, it'll be fun with a few guys on a track where the goal is more fun than competition/winning. They look awsome going around corners and drifting together. Lots of fun.



war666 -> RE: 1/8 GT? (4/24/2008 5:51:40 AM)

So i have and lrp .28 aside from using the ofna clutch nut do i really need to upgrade the clutch and all? i can make a motor mount not a problem on that. i only ask because my stock 3 shoe clutch for it ( its on my mgt atm) has never givin me problems ? any info would be appreciated

Just a FYI the ultra GTP 2speed wont work with most buggies becuase the bearing useing in the center diff mounts its HUGE compared to ur average buggy bearings just thought id share that info with you, the inferno gt and ofno GTP are no where near interchagable they are very diffrent

i agree tho ud be alot better off starting with a kyosho buggy, also another good choice would be the XRAY XB8 buggy TQ buggy. The TQ was pretty much of a copy off the WC777 AND they sell for cheap as hell on ebay all day long, i picked up a roller TQ in awsome shape a few months ago for only 86 dollars shipped to my house and its one hell of a buggy



ThunderbirdJunkie -> RE: 1/8 GT? (4/25/2008 2:57:51 AM)

Oh, I wasn't talking about using the 9.5/GTP's 2 speed in another car...just mentioning that the 2 speed and body alone are worth the extra price of the RTR over the roller ARR

I hadn't thought about an Xray TQ...I'll look at those too.

War, just the engine should be fine. it comes with a pipe too, so just plop in your engine and electronics. with that LRP the thing should RIP...but 14t sounds a bit small to me, so i'd go up to a 16t clutchbell. I have no experiance, other than running a .28 in a 1/8 buggy, so hopefully these other guys can chime in on that.



Mufasa_719 -> RE: 1/8 GT? (4/25/2008 4:04:14 AM)

dont forget you could always pick up the Inferno GT and sell the "GUTS" on fleebay. make some money back on the car and throw your own goods in[)]

the TQ is a bad ass car those hudy CVD and cups will NEVER wear out, i really enjoyed mine and only got rid of it becuase i traded it rolling chassis along with a old 3PK radio for a RTR HPI baja, if not i would have kept the car

as far as a 28 in buggy U BETTER GEAR THAT SUCKER UP the LRP28 is a bad ass motor i got one in a inferno gt, u can start with a 20T bell and still go higher



rcnitrohead -> RE: 1/8 GT? (4/25/2008 4:39:42 AM)

Settle on thrashing the Savages? Cmon Thunder! Get those babies airborne and have some fun, none of this on road nonsense[)] lol I'm just kidding, I want an Ofna DM-1 so bad[:)]



ThunderbirdJunkie -> RE: 1/8 GT? (4/25/2008 7:06:40 PM)

heh...I still have to assemble them the rest of the way[&:] I don't have my LST shock mount kit or my old-savage suspension arms yet, either...or Vig's low profile towers...but I've got the shocks for both of em!

Miami...I'll be running a bumpstart STS 28 5 port in whatever I get...Already have the engine/pipe:D



ferrarimk13 -> RE: 1/8 GT? (4/25/2008 7:26:08 PM)

mm, talking about xray, how about that new 808, CF buggy? mmmm

Cool, I'm stoked to hear that. I'm planning on using the LRP 28 Spec 3 motor in my IGT when I'm ready. I already swapped in the Ofna shoe type 2spd tranny and am using the Ofna CB & pinions. http://infernogt.proboards102.com/index.cgi?board=drivetrain&action=display&thread=1208

I really like that transmission, it's designed very well and is built rock solid. It also shifts very positively.

Which flywheel & clutch would you recommend for the LRP for use with the Ofna CB? Also, any suggestions on gearing? I see you mentioned a 20T bell, what spur ? I've got a range of gears I can use for the Ofna setup.

I'll be swapping in a Fioroni Ergal 4mm chassis also. I've got to do a little milling to make clearance for the 2sp gears but that's about it.
