Agreed the pitman was fast Now the driver just needs to get better.

the S5 is a great motor, been running pure for me with the stock hobao pipe, dynamite header. it runs pretty good with the jp-4 too.

ordered a s5 last night stoked to hear its doing good for yeah hope it goes good for me ill also have a jp-4 so good to hear its a good combo

nope os all the way i got the xz on my that will beat anything at the savvanh track in georgia fast as hell man

I run a Go Tech .28 in my HST Pro! I race at RC Madness in Enfield, CT. I'm running the stock Hyper pipe with the Go and it was as fast, and faster, than the Ninja's, O.S.'s and Rossi's! I was even pulling on the buggy's in the straight during practice. I got a lot of congrats for being the only truggy that day to clear a difficult triple, with a 4' run in, after a hard-left table top!

The .28 is my second Go engine, I have the .21 7p in my 8ight. Great engines for the price! ($180-$190 shipped on Ebay)

I got my HST Pro at the end of last season. I have only raced it twice and I love it! It's wicked plush and with a little mod, it turns like an on-road car! So far, I'm the only one at the track with the Pro and when I'm driving good, it can turn inside any other truck on the track I couldn't be more happy with my first truggy! It's gotten me to 2 A-mains and a 1st place B in the two times I've had it out!

I have made a few changes from the stock kit. I'll try to post some pics tomorrow!

Are there any aluminum shock ends part for the hyper st pro?

ugg so my reciver never worked properly so sent it back (spektrum) 3000 and got it back last week had 1 race with it started breaking in my motor today idled a tank putted around about 4 then started gettin on and off it today and start driving it up my streat lost signal and spektrum did not go into fail safe!!! took off at full throttle hit my neighbors truck tire ... whole front end on it is pretty much jacked up cnc front brace twisted both servo saver post things gear box bumper shock front cvd that top plate that the front chasis brace goes into just abounch of stuff im wayy bummmed started up to motor after cooled down idk how hot it got but i know its not good for a new motor to happen like that... soo pretty pissed off spektrum better send me a new one asap they said they tested it and everything binded corectly ect ect .. obviously something is wrong with it well at least i know that the rb s5 is a fast motot

Did you bind the spektrum failsafe with the brake on? Did you test it by turning the transmitter on, then reciever, then turning off the transmitter to ensure that the brakes go on when the signal is done or does it just stay neutral?

yeah i had it for failsafe to lock up brakes and carb fully closed like i don't get it seems like it picked up anotehr signal or something

Did you change throttle/braking servo's lately and maybe had the servo direction reversed so when you orginally bounded it instead of braking it went wide open? Just thinking of scenarios cause some idiot (namely me) had that happen.

hey I bought some Jconepts half up rims for my hyper and I want to fit badlands to them, has anyone tried this before?? I have test fitted them and they seem to work best when you put the tyre bead on the INSIDE of the inner ridge of the rim. Also the stock proline molded foams dont seem to stretch too much, so I will probably use some Savage foams i have lying around.

I have read somewhere about people cutting the inner bead off the tyre to make it fit.

nope all same stuff no reason for it to have changed

SOunds like you got a faulty reciever then.

How do you do the Hyper 8 Box mod? Please post the link if there's any. Is there a rotostarter that will fit the stock Hyper ST RTR engine? I hate pull starts.

Thanks

Its in this thread. I think like 10 pages back. Go throught each page starting at 20 and you should find it. I don't know of anybody using a roto start, but don't know why you couldn't.

I used to have a roto start on my macstar 28- I think it was called the tiger drive, I got it at my local LHS, this was before I changed that engine out for the Jammin .28.

Here's some pics of my ST Pro!

My pit guy(Justin) loves this!

More pics. The files are large!

I just started racing. Last weekend was my 4th race! I TQ'd the 1st round and then had two DNF's due to engine issues(that's what I get for trying to fine tune between races)! I got it to stay running for the Main and took 1st! Every other truggy was a Losi except for my fellow club member's Mugen!

This truggy makes everybody think I actually know how to drive! It's has definetly gotten a lot of attention at the track!

it does have that power, good job. if its not cluch, radio, battery or diff issues (my fault) i would finish a main once in a while.

Thanks!

I started with using a ProTek 2000mah lipo because I didn't want an external battery! It works great, plus I was able to fit everything in the receiver box! (No mods needed!!!) I get great run time even with those overkill servos!

The only issue I've had with the clutch so far is one blown bearing!

I've solved the diff leakage problem I was having by changing the way I fill the diffs and by using a little Racers Edge O-ring Sealant! I just figured out how to get the maximum amount of diff oil in the case without trapping any air and without getting any oil on the rim of the case where the crown gear sits! I even filled the recesses under the large bevel gears with oil! I fill the cup up almost to the top of the satelite gears and then I put the other large bevel gear in. Then, I top it off with oil an fill the recesses on the bevel gear! Before I put the crown on, I remove enough oil for the output shaft to go in without causing displacement, then I line up the pin with the bevel gear and the screw holes with the case and tighten away!

Oh, I also use a very small amount of o-ring sealant on the crown gear o-ring. The main thing, is to make sure the rim is free of oil! If there is oil between the crown gear and case you may think you have tightened it all the way when you really haven't! Over time the oil squezes out and leaves a gap! I noticed this when I let it sit for a while, I went back an hour later and was able to tighten it some more. Keep it clean!!!

I know you weren't asking for advice but, since filling my diffs this way, I have gone through 2 race weekends without even a hint of leakage! Just figured I would share!

yup like i said i sent it back once the supoosevly fixed it and thought it all be good o well i guess sucks won't be racing truggy for a lil while parts are over 100 to fix all [:@]

hi guys,i noticed that at full turn the wheels are rubbing on the arms.should i use the extra set of hubs,i believe it will offset the wheels a few mm.the extra hubs have the pin hole closer to the edge,i tried it on but i have to shim it to get rid of the play.so which hubs you guys are using.thanks

I use +2mm hubs with JConcepts Rulux Half-Ups half offset rims. Seems to do the trick! The JC's have a nice bevel around the wheel hex but you still need to space it out with at least a +2mm set! You could also use +8's with a standard offset wheel and get the same effect! If you run standard offet, and are intersested, I have a set of +8's I could sell for $25! I used them for about 3 minutes with my half offsets. It was too wide for me!

I am using 1/2 offset Proline LRP rims with LRP holeshots and have no issues with rubbing with full turn.
