hi bro i got a Hyper ST RTR too. put in the RB C6 BB 7T and this baby run like a cheetah... surprisingly it really turn better than some other truggy that i own. considering it is a RTR.

What hop-up do we need to turn it into a PRO KIT?

love the tyres. i think it is between half offset and standard offset..

i will tuning it for my next race in SEPT. hopefully i can come in 4th too... show those rich kid that RTR really can ROLL....

i dont know how the single rear body mount will go as i think it will tear compared with the rtr double mount, a bit like the hyper 8 mount it is in a funny spot but a small peice of alloy will fix this i think.the main hope ups are front hubs and diff supports i feel. i will tell you once i get to run it as we are getting flooded at the moment and racing has been cancelled for the weekend.

out of the box they are a good truggy and the only thing is to fit thicker oil to the centre diff for more drive... it is a good truck with tough parts but the engine is the only weak link. so bite the bullet and get a good engine and you will at the pointy end straight away.

yeah the pro is the way to go if you can get 1 and as killer says thicker centre oil a friend of mine is the New Zealand importer and he went to 15000 or 20000 to stop those fronts ballooning on power and it still turns in like you wouldn't believe

i cant wait till sunday as it race day and there will be alot of proes out ( um that sounds bad but it is all good as they do the deal) and we are all setting up still waiting for our round of local cup meets. this is the first car i have built and it was fun apart from the kids taking bits. it looks strong in all the areas where weaker parts were, not that i broke any apart from my knunkles. lets hit the big air and see how it flies

i am in oz and we got different tyres to those. the tyres that came with dont grip up at our clay track very well and most of us use the rtr tyres like you have.

Hi. i need help with tuning the Mac Star .28 engine.
can some one tell the the base staring point for all the needles or a good starting point? i sort of have adjusted them.
the engine dies when i accelerate. not at top speed but dies when i put on the trottle a bit fast. it dosent die when i do it slowly tho. does that mean its too lean/rich for the low speed or the high speed or the idle?? it also dies when there is presure on the wheels like climbing from a slow run.

i have broken it in for 3 tanks , and ran at mid speed for about 4 tanks.
pls help.

How much difference is there between the RTR and the Pro? I see the Pro has aluminum shock towers. I think it's cool that Ofna sells this as a full kit. a friend of mine is leaning towards this truck more and more each day. lol. This week he says he is going to get the ST pro. We'll see what next week brings. LOL.

mainly the difference is it has aluminum shock towers, aluminum arm stays, I think the braces are different too and some parts are now carbon fiber
Nevermind, genius got it covered already.

new question, what is the size of the fuel tank? Ads say 125cc but the mags say 150cc.
