Horatio comment on the Power of STS D30M rc engine!. Please check his other review at his own Horatio category.
Just ripped through another 47t Plastic spur, so enough is enough. Depending on how I’m using the STS, I can make the plastic spurs last for a while, but as soon as I get aggressive with the throttle, the STS eats them alive. Simply rips the teeth off. Then melts them.
I’ve resorted to using a steel spur and hardened clutchbell. After careful consideration, I decided to use an RW 47t Spur and 18t Hardened clutchbell. It’s a fairly heavy option - BUT - unlike some certain steel spurs, it doesn’t resemble a circular saw!! It’s just as wide as a stock plastic spur, so in theory it should be kinder to the clutch bell and tooth wear should be acceptable. All metal gears go ‘pointy’ eventually, even hardened items on buggies, so it makes sense on the Savage to get the load spread across as wide an area as possible.
The HPI dual brake kit is working after a fashion, but it’s not as effective as the old CNR setup it replaces. The brake hub is lasting well after some serious abuse, but the brakes are not very progressive and have a tendancy to snatch, even after bedding in. In my opinion, the disc rotors are too thin.
The thicker CNR discs were more stable and consistent. Also, the CNR Carbon fibre shoes required no pad material, but still brought everything to a smooth commanding stop.
I mentioned about the wear on the CNR brake hub, well it’s a shame there isn’t some way of combining the best elements of both setups in one product. The larger hex size of the CNR hub would be really nice in a hardened steel item, similar to the smaller HPI size item - just bigger to suit the CNR rotors. Otherwise, all the CNR components are more effective.

What is with STS #0702 Tuned pipe? This pipe is designed for .28 - .30 sized engines, in particular the STS Monster truck engines. [editor: STS D28M and STS30M]
It’s very nicely made and has a nice polished appearance. It comes supplied with a manifold/header pipe, silicon gasket, exhaust spring and coupling springs (between pipe and header).
Unfortunately, the manifold supplied with this pipe does not fit the HPI Savage.
It appears to be suited to Truggies, where the pipe fits down the left side of the engine. Additionally, the shape of the manifold is incorrect for Savage use - it doesn’t fit close enough to the engine to allow clearance for the rear-right Shocks.
My Edit in-line manifold (#ED100227) arrived yesterday and is now fitted to the STS #0702 pipe! It works a treat. The only minor modification needed is to the the exhaust mount wire, to fit the slightly different dimensions of the STS pipe!
http://www.rc-edit.com/?lang=en
The Edit manifold has a nice finish, and fitted very well. However, I noticed a lip that needed to be dremmeled prior to installation. The STS 0702 pipe is very different to the HPI ribbed item. The main thing I noticed was how much more pressure there was to the tank, so much so, I had to lean the main needle by 1/2 a turn! Power delivery is slightly smoother, less explosive and seemingly broader. Fuel consumption is improved yet the top-end seems even better.
Okay, I’ve put the Savage through a good bashing session today. I mean properly thrashed!
Between high speed runs, being chased by a mad dog and catching some air, my Savage was certainly put through it’s paces. 18/47 gearing on the 3 speed certainly gives an impressive top speed with the STS, as well as constant power wheelies. The truck is very responsive in the air with this engine, and I very nearly pulled off an insane back-flip off one of the naturally formed jumps. I endo’ed the landing, but it was mental!
The damage after the day’s antics? Tooth marks on the lower arm and a broken spur!! (Missing teeth this time - no melting issues!).
I also need another gallon of fuel.
The diffs, remarkably, are holding up very well; the brake hub, diff outputs and drive cups etc are worn and need replacing, but to be fair these items already had many gallons through them and still work after a fashion! The old Savage has a new lease of life - it still rocks!

Update on the Fioroni Turbo Sliding Clutch:
Well, had a bash around with the HPI Savage today. The engine is tuned and the power is awesome. The Fioroni clutch exhibits awesome bite now and the truck pulls power wheelies with very little provocation. There is no clutch fade and the power-band is so aggressive and broad with the STS D30M, that extreme care has to be taken at all times not to put the truck on it’s lid.

Another updates on the Monster Truck Jam.
Popularity: 14%
Technorati Tags: Monster Truck Jam
Well, I’ve run about 7 tanks of fuel through the D.30 now. I’m leaning the needles to a point where I can blast the Savage around, but the throttling is still rough at this stage with the needles set rich. The engine runs cool on the 25% O’Donnell fuel. The pullstart has been very reliable and the engine starts very easily. I’m not a fan of pullstarts and I will ‘upgrade’ to a roto backplate in due course, but the pullstart is pretty rugged thus far.
The engine was nice and tight when I got it, but not so tight as typical competition engines. The engine is eager to start and stays running even while warming up. The piston never once got stuck at TDC, even during the first couple of tanks.
The Power delivery of the D .30 is very agressive to say the least and even with the needles set rich, the engine hauls the Savage around very rapidly on 18/49 gearing. And it’s very loud on the Ribbed exhaust. As in ‘very’. The engine is showing early promise and it’s going to be a screamer, without a doubt. Cue dremmel, stage right……
The Fioroni Turbo Slider is working, but the shoes are slipping slightly. It may need some bedding in, but so far the clutch doesn’t have enough ‘grab’ to lift the front wheels. Unlike my stock 3 shoe clutch
I have a small piece of silicon fuel tubing slipped over the TVP on the right side to protect the edge of the STS engine and the header pipe. It works a treat. It’s something I’ve always done with my Savage.
While I’m running the D .30 rich, I will say it consumes fuel at an almost alarming rate……roll on the time when I can set the needles to optimum settings.
More updates to follow….

Horatio second update on the STS 30M
STS D.30 update:
Well, the STS .D30 is very similar in size to most NS series engines. It fits in the stock engine mount without too much drama. However, I did need to relieve the inside edges of the engine mounts so that it fitted the STS .D30 crank case.
I left the head shims in place for the break-in/running-in period. I checked the main needle position, closed it off gradually - whilst blowing down a scrap piece of fuel line - until the main needle was shut off. I opened it 3 turns from this position. Note - I didn’t crank it all the way down till it couldn’t physically move anymore! That’s not my definition of ‘closed’ for any main needle, which at the end of the day is a precision metering device.
A lot has been said about the STS factory needle position already, with certain people even arguing with respected dealers like Ryan. At the end of the day, the exact number of turns is arbitrary anyway. But you do need to find a rough ball-park starting point. 3 turns open from the shut off point is a good place to start for most engines.
Before I could start the engine, I needed to install it into the truck with my choice of clutch - the Fioroni Turbo Slider, with carbon shoes. The flywheel was actually designed for Kyosho buggies, so there was an element of doubt whether it would actually be compatible with the HPI Savage. Most people use Mugen size flywheel. But I figured a work around, and so far it seems ok. The holes in the engine mounting plate had to be enlarged slightly to move the engine rearward slightly.
Clearance between the clutch bell and the 49t spur is minimal using the Fioroni set up, but so be it. I should be using a 46t spur anyway!!
After installation, I needed to adjust the linkage to the carb and make a slight bend as well. I also needed to physically remove the servo horn and adjust it accordingly. The brake linkage needed adjustment and both the sub-trim and EPA needed to be re-set on the radio. This is due to the different carb, and the slightly larger slide travel compared to the old NS .25 engine. Nothing too taxing here, but worth noting.
The engine started firing on the second pull after ‘priming’, but the engine was far too rich to stay running, even with the glow starter attached. The engine sprang into life after I turned the main needle in about 1/2 a turn. I warmed the engine for about 2 minutes, then blipped the throttle and removed the glow. I ran 3 tanks through, with the Savage lifted clear off the ground.
I’ll finish off the initial running tomorrow!!

webmaster note:Yes, found this post in the rctech about STS D30M engine. Thanks to Horatio, this post should be in this blog. So i posted on his behalf.
On the subject of STS……..
I decided to have a good look at my new engine. Now there’s been a fair bit of hype surrounding these engines, not just the MT engines but the TC and buggy engines too. After some initial niggles, it soon became clear that these engines perform extremely well at about half the price of typical competition engines.
The engine I received came protected in a vacuum sealed bag within a very nice foam-packed box. The excellent instructions cover all the important things in a very concise way, with some occasional ‘quaint’ English thrown in, just to amuse us!
Here in the UK, most of us have had a fair bit of snow over night, so running in at this stage isn’t a good idea. Instead, I stripped and checked my STS D.30’s internal parts.
All I can say is - WOW. Bear in mind I’ve had lots of decent engines in my time, so I’m not easily impressed. But this engine is so well made, it’s almost too good to be true. The quality of the casting is first class. The inside of the case was perfectly clean, properly lubed with absolutely no sign of rust or even the merest blemish on the crank or the knife-edged con-rod. 10/10.
This is one of those engines that you could fire-up straight away, without any need to flush or clean first. Much like OS quality in terms of finish.
The carb isn’t quite as good as an OS, nor would you really expect it to be. It’s a little bit sticky at the closed side, but presumably this will soon be eliminated with use, once everything has had a chance to bed-in. Otherwise, the needles, slide, spray bar and carb body look very nicely made.
The screws all needed a little torque to pinch them up, so I decided to de-grease them and apply some thread lock. I did this on the back plate and also on the pullstart assembly. As the plastic on the pullstart is potentially incompatible with solvents present in the thread lock, I ensured the thread lock was put only into the holes of the alloy casing, therefore eliminating any contact between the plastic and the thread lock.
The button head comes supplied with what looks like a 0.1mm and a 0.3mm head shim. After run-in, I’ll probably stick with just the 0.3 shim on 25% fuel.
Remember the problems I had with my trusty S 25 when I first inspected it? Looks like Nitro Star could use a few lessons from the engineers at STS. And the K 4.6 - remember the interesting ‘pitted’ piston that they came supplied with in many cases? Both engines cost about the same. Hmmm.
This is all well and good, but the proof of the pudding is in the eating!! I’ll keep you updated with how the engine break-in goes. In the meantime, I need to get hold of the STS .21 Tuned in-line pipe/manifold and the Fioroni Turbo Slider clutch. More £££.
Just added, New tuned pipe for D.28 and D.30 engines will be available 12th Feb, #0702.

Yes, you read that correctly. its the HPI Savage with 10 seaters. I was browsing for good story and i end at this great site. But it is NOT the 1/8 scale we used to drive. its more to 2:1. Hahaha. Its the real Monster truck brought to you by Extreme team Ride Dot com. The company belongs Mac and Liz Plecker at Williamson Georgia. The HPI Savage is actually a 10 seaters F-150 monster ride truck. thanks there mate.

Well I started out with a Savage X kit I got this year in June. It was good and all but I knew I would fall into the money pit called the Savage. So I slowly started upgrading her, and well here is my project story.
This is what is looked like before I got all the parts:
First major thing I got for my Savage was an STS 28, I have heard good and bad things about this motor but I got it and I wanted to see the hidden power in this beast:
The next thing I got was Aluminum Diff Cups, Diff Cases and Bulkheads, and CVDs, HD Wheel Dogbones, HD Drive Cups all round:
Then I encountered a problem which was that the Savage X shock towers didn’t work which I knew but I had to modify them:
Then you get this:
Then the next thing I got which means alot to me where Twisted Toys LCG Stock Length TVPs:
Then I bought some goodies for a Mid-Tank Mod, I already had some stuuf for this before I just needed a few more things:
Then I put it all together and this is what it looked like after:
Wow I have spent alot of money already but there is still one more important thing I need, clutch shoes. So I ordered me some Nova Adjustable Clutch Shoes:
Now my Savage was complete and I could drive it. Presently and about half a gallon or so later she looks like this, and let me tell you this motor has alot of friggin’ power:
If you have any questions of what I did just message me here and I will get back to you ASAP. Tell me what you guys think also. The only damage that has came due to this is a broken flywheel and a output dogbone. Thanks for looking.

This STS D30M engine has not reached our shore yet, but the power already! Hahaha. I’ve been hearing people lose their spur just by one pull of the trigger, worn out carbon clutch and many more. I just cant wait to get it on my truggy. see whether it can wheelie my truggy or not. Hahaha.

Done by my friend Dracy69(rctech), he took the trouble to show us how you open it up for service … as he said i quote:
This is a basic overview of the Savage X. This will show you whats new on the truck and how the truck come’s apart. The truck was a little dirty but it shouldnt hurt too much.

Check this video.. whether can play or not..its your luck then! Hehehehe.
Here i quote from him: at page 200 at rctech Forum.
Check the top speed - not bad for a 2 year old S 25 engine!!
Note: no wheelies in this video because the clutch needed a service and I was running 18/49 gearing.

The HPI Savage Throttle Ofna mod by Horatio(rctech) quoted here:
The OFNA throttle mod is the Savage equivelent to a 1/8th buggy throttle linkage. Of course you don’t need seperate front/rear brake linkages on the Savage (the Savage has only a central brake and no centre diff), but you can enjoy all the other benefits of a greater adjustibility, better mechanical advantage and a stiffer servo horn/control arm, thus creating a more responsive throttle action and stronger, posititive brakes.
To see picture … and mid tank / throttle mod
