Status: offline 		Hey guys, got 18 sets of Hyper ST carbon fibre towers and chassis centre braces.

Saves around 90 grams off the weight of the truck, which lowers the centre of gravity for better handling and being lighter means longer run times as you have to use the throttle less. Car feels nimble now compared to before, which was great anyway. I have done numerous races with these and have not had one breakage.

The complete set includes:

Front shock tower - 4mm carbon fibre
Rear shock tower - 4mm carbon fibre
Centre chassis brace - 5mm carbon fibre



Just send me a private message and I'll let you know the details.

Status: offline 		I've got my Hyper ST in bits and am going to give it a good service ie new spur gear, clutchbell, bearings, engine and servo's not sure about a couple of things though. What size of clutch bell should I use with my Axial 32. I'm thinking of using a 16 tooth one or even a 17 tooth one. I am also not sure about the standard clutch is there something out there that is better than the standard one. Also a bit confused with diff oils it ran 10,000 front 60,000 mid 3,000 back but I got quite bad understeer on dry gravel. That might have been down to the crappy macstar .28 taking ages to rev up onto the power band. I also heard alot of people changing the fuel tank what is the tank that works best.

Status: offline 		Yes that is the oils in it. It also has 30w in the shocks but the car bottoms out very very easy. I needed to put spacers in the springs but it makes it bouncy especially on the front and the back bottoms out and lifts the back of the car off the ground. I was going to put 50w all round. The macstar engine is in great condition no play in the conrod and smooth bearings good compression. The best I can get it to go is just a bit too delayed at the bottom mid range and top end is good but I have had it to the eyeballs with poor response so I have a 32 to go in it. Was thinking the 17t clutchbell might be good but having second thoughts due to my 28 being poor low down might go for the 16 or even 15 any info or feedback would be greatfull. I'm thinking of going with 5,000wt in the front 3,000wt in the back but not sure anymore what to do with the middle.

Status: offline 		The thing about the Macstar engines is- My mate and I thought they were really good (getting back into the hobby) untill we went up against some half decent engines.
You could play around with the glo-plugs as well to get a good tune. But now you have the Axial i probably wouldnt bother.
What you may want to do is have a go at modding the Macstar engine for giggles. I have found it responds tomodding really well as my mate got into modding some of the cheaper engines we had lying around.


And if you stuff up the mod ? Its just a Macstar.


you would be surprised at how hard we got a Vertex engine going...lol

Status: offline 		And get yourself the JP-4 pipe rather than the JP-2. Much better overall pipe and better on fuel too. It also seems to work with virtually every engine we have tried it on, so good for when you need to upgrade the engine in the future.

As for the Mac, I found that on my sons car, when I removed the pull start and put a bump start on, the engine ran a load better, it was like a different engine. As Kal said above, when you run against a good race 21, then you will see how poor the Mac actually is.

Status: offline 		I was thinking of modding the Mac star engine. It has a screw in the side just below the carb for a boost bottle it came out of the factory as a bump start engine. I did try getting a good tune with a number of plugs and found the R4 to suite it the best any hotter and it started to pre ignite (Bad for the conrod) so I tryed to tune it with that and also found it to be inconsistant but that might be the fuel tank. I didn't check to see if it had any shims in the head it is completely standard so I'm not sure if it would have. I have just got a new centre diff and set the oils at 5,000wt in the front 7,000wt in the centre and 3,000wt in the rear. I Also got new suspension pins wishbone and anti roll bars to take away all the play. And new MG995 servos and a 1500mha 6v battery. I'm going to go with the 16 tooth clutch bell and see how it goes. Also got a new shell and new bearings and wheels and tyres will post pics as it won't take me long to get it all dirty and scraped again.

Status: offline 		K, with the Mac, try and use the Mccoy MC-9 plugs, I found these work a treat on these engines. Forget about the boost bottle, you gonna get not much return for a lot of work. If you need more power, get a decent race engine, you won't regret it.

Stick with the 14T clutch bell, I never ever felt the need to gear it up.I was clearing the doubles at Clanfield with a short run up with half throttle and sometimes less.

With regards the diffs, I have gone to much thicker oils and it has made a heck of a difference to the handling. I now run 10K front, 30k centre and 2k rear. With regards to the shocks, the oil you use depends totally on the surface of the track you running at. I now run Hong Nor Super Big Bores, but from memory, I used to run anywhere from 30 up to 55 depending, with slightly heavier on the front than the rear.

As for the servos, get rid of those MG-995's. All you need is a failure at speed on the steering or on the throttle and end up with a runaway, they are notoroius for failures. Save up a bit more and get some decent servos, like the Align's or the Savox.

Status: offline 		I've already done the diff oil but I was actually thinking about the Savox servos it came down to 2 one was 12.5 Kg/cm with 0.08secs and the other 20Kg with 1.13secs both the same peice around £55 each is 12.5 Kg enough or should I go with the powerfull 20 Kg ones. Have you got any videos of your hyper with a proper racing engine in it. I was thinking if I am not happy with the Axial I will sell the 2 engines I have and try and get a Ninja MR28 but I can't find anywhere that sells them. Apart from America. Oh last time out I wrecked my spektrum 2.4G reciever as a little drip of water got in it is there any mods to make the radio box water tight or are there any after market ones out there.

Status: offline 		The 12.5 kgs is a lot quicker and will be strong enough. My Ace DS1015 that I use is the same and is plenty for my Hyper. You really need the steering speed when racing.

Unfortunately, I do not have any video of my car, but if you search on youtube, you should find loads of videos showing racing engines in the car. I woudl stick with a good race 21 instead of a 28, purely for the runtime. Nowadays a good race 21 is not that much slower than a good race 28 if at all. I have beaten guys who have been racing longer than me with my RB WS7 III while they were running OS 28's and the like.

As for the radio tray, unfortunately, we are stuck with what we have, or you could try one of the radio trays that other guys have used, including the Kyosho and the Hyper 8.5 box.

Status: offline 		What would be your top 3 engines and in what order for what reasons. I hear alot of the LRP engines the ninja MR engines not as much though and the RB and OS engines but don't hear the differences beween them if there is any. I've read that the RB engines are pretty much the favourite and the OS 21 V spec 2 is popular and the VZB. LRP have a spec 3 engine which I hear alot about but not much of the Ninja MR engines.

Status: offline 		I LOVE my OS vzb-v-spec and OS Speedtuned they're great engines but a bit much for my Noob level racing.

So i got a Go 3 port race engine with OS carby ( I always seem to have trouble with GO carbies ). i LOVE OS Carbies !

Nowhere near the power of the other two but a great engine for an entry level racer learning how to drive on a track.


Once i know what i'm doing, then i can throw the OS back in it.
