Turnigy SCT owners thread (including Desert Racing buggy & Kyosho Ultima)

[300bhp/ton]

There seems to be a small, but maybe growing community of owners of these. For those that don't know, Hobbyking sell the Turnigy SCT 2wd short course truck and Desert Racing Buggy. These are based on the Kyosho Ultima SC and buggy and even share some parts. 

 

There is also the Trooper SCT 4wd which is a 4wd short course truck.

 

All of these models represent very good value for money and the SCT 2wd can be had in kit form for only $88 (approx

[300bhp/ton]

Things to report so far.

 

The metal fixings (screws and the like) seem very rust prone. I'm guessing the previous owner must have used this on wet grass or similar and then left it in a garage or somewhere it didn't dry.

 

I'll be swapping to some stainless screws at some point.

 

The bodyshell is very thin and already has a small split in it. I think a replacement shell will be needed in the future.

 

Front alloy shock is leaking.

New servo installed. Went for a Trackstar one from Hobbyking.

 

I'm running it on 4.8v from the Rx at present, but does support 6.0v via a BEC and slightly improved performance.

 

Quite impressed with the servo considering the money. It's 1000x better than "standard" servo's of old. It's fairly speed, very precise and seems to have plenty of power.

 

 

Stats say it's 12kg on 4.8v.

Currently running with an LRP IPC v6.1 ESC and a Reedy 9x3 (9Turn Triple) brushed motor.

 

Managed to try it out in the field at the weekend. Sadly only a short run as the pinion gear I was using didn't fit the motor pin length very well.

 

Handling on grass was poor. Not sure what weight oil Turnigy use, but to me it seems to soft and too much lean. It was very very rapid however. This was on 2S LiPo.

Goodies arrived from Hobbyking a couple of days ago.

 

I've swapped the optional spur gear on that is now a more sensible 48dp and I've changed pinion gear to match.

 

I got some of the alloy upgrade parts.

 

 

Front bulkhead/suspension arm holder:

 

Rear suspension braces:

 

It already had the alloy front brace:

 

Front carriers and knuckles (also got rear alloy carriers but forgot to photo them:

 

A word on the front ones. They are slightly different dimensions to the plastic parts and the pin holding the knuckle and steering arm together is too close to the stub axle, meaning it doesn't fit!!!!

 

Solution was to grind/sand down the stub axle and thin a section of the shaft, literally only 0.5mm maybe less. It now fits, but was a bit of a ball ache to do!!

 

Also installed new micro Rx.

[300bhp/ton]

Next up was to sort the shocks out, I stripped and re-built the front leaking one. It used one of those cheap and nasty spring locks to hold the seals in!!

 

Horrible things to take apart and refit.

 

The seals consist of 2 small do-nut O-rings and a plastic retaining washer. I swapped one of the O-rings out for a slightly fatter one I had laying about. It seems to have stopped the leaking, so will need to keep an eye out.

 

While stripping down the shocks I can see why they all felt a bit soft, the piston doesn't really seal to the inside of the shock body, so a lot of oil gets by. I normally run 30 and 35wt oil in my Losi's. I've opted for 100wt on the SCT, although it does seem a little hard now, so may back it off to 70wt after I've run it.

 

I've also changed all of the shock positions, hoping it'll handle better next time out.

 

 

[Drnose]

Got two of these myself.

In summation, i'm fairly impressed, though do watch out for the tyres! The insets seem to melt almost immediately. I managed to rip one to dickens on grass simply by throwing in a 7.5t brushless motor 

Still, i have a soft sport for SCTs. 

Nice write up, keep it coming 

[vrooom]

I like quite of those... but I cant justify the shipping cost... what is difference between real deal and hobbyking clone.

[Drnose]

There are some fairly cuttish corners.

All phillips heads, weak tyres.

But the truck itself is actually not bad. The way i test a cars durability is to give it to my better half. If it's still together after her racing it round the track (off the track, in the trees, into the marshalls) then it's a solid piece of kit.  And actually, when i applied this test, there where some really spectacular crashes, and the worst that happened was a shock coming off the mounting due to some gubbins (that being me) not threadlocking a nut 

 

Edit: As to the second, i've never actually seen one of the real deals in the flesh, so i can't help ya there :<

If you buy from the UK Warehouse shipping is pretty low and there will be no duty to be stung by. Not sure you can get anything remotely similar for the money.

 

Compared to the Kyosho Ultima SC. It's a bit mix and match. Some bits are almost identical and you can even swap parts. Some bits are improved on the Turnigy such as the rear plate that holds the rear suspension arms in place.

 

But a few cut corners such as cheap screws and crappier wheels and tyres and bodyshell. Although to be fair, these are all easy bits to replace as an when you need to.

 

I've read a detailed review of the Desert Racing Buggy and the only faults it has are the exact same issues the Kyosho one suffers with.

 

So looking good so far. I'll report back, maybe with a vid of how I get on with it at the weekend.

[logicpaul]

Hi everyone I am impressed by the hk desert buggy having got one for a relative at christmas. There are some week points to be fixed/ upgraded straight away.

Stock shocks are not really fit for purpose so upgrade asap, the same with the servo, I have fitted a hextronic servo from hobby king for about a tenner and its an excellent upgrade, I also upgraded the shocks with some random alloy ones from old derelict kits.

One down side is part support is non exsistant in the UK but they are very cheap from the hk international wharehouse, postage is not cheap however!

There is a lot of compatible parts from other kits; obviously the kyosho DB is the main contender.

The spur gear from the losi 22T (TLR3980) fits, the slipper pads dont quite match up but it functions well enough.

The driveshafts from the hpi bullet also fit well and are a bit more heavy duty.

All in all I think the turnigy DB is a great first rc or cheap entry in to the hobby but it does need those upgrades pretty much straight away.

Looks good chap, but you may get more coverage if this was moved to the SC section

A very good point!

Update 1 from the weekend.

 

 

Handling is better now, maybe a little too hard on the bumps, but it still wants to grip roll on grass. Tarmac handling is very good though.

 

Problem one. When you get it doing a wheelie, the body seems to act as a parachute and after 10 feet will flip the truck when at speed.

[300bhp/ton]

Update 2 from the weekend.

 

 

Sadly it seems the 48dp optional spur is made from chocolate. I'm hoping this was just a bad batch, but I'll have to wait for some new ones to arrive to fund out.

 

Gear mesh was perfect. It started off with a single tooth snapping off:

 

Decided I'd got nothing to loose so ran it again.

 

Lasted 40 secs maybe, again gear mesh was spot on.

 

 

As you can see the spur gear ins't mashed up, but the teeth have literally snapped off, some at the base and some about half way along.

 

I was running the Hobbyking supplied 17T pinion that's listed as a spare for the SCT 2wd.

 

Going to refit the white 32dp spur gear, but still waiting for some 32dp pinions to arrive.

[J.K]

Have you checked your motor mount? If something isn't tight enough then the mesh can change whilst running. I stripped 2 spurs before I realised the motor mount wasn't tight enough!

Or it could've been caused by debris of course.

[300bhp/ton]

Yeah the motor was secure and there was no debris. It wasn't the mesh, if it was it would mash up the teeth through friction. This has clearly snapped the teeth off, some at the base and some at the mid point.

 

I'm hoping it's just a manufacturing defect, either that or these spur gears can't handle a 9x3 brushed motor on LiPo's. I'll order some more from Hobbyking as they are only $1.29 each and I'll use a different 48dp pinion gear with them.

I hadn't seen this topic before, so I post my message again

 

My setup:

 

- EZRUN Combo 9T (4300V) + 60A V2.0 ESC

- Turnigy 1258TG

- Upgrade Front susp Arm

- Upgrade Wheel hub

- Upgrade Rear susp Arm Holding Block

- Turnigy nano-tech 4000mah 2S 40~80C

 

I didn't run much because I had a problem with the steering. I must say that this is the first kit I mounted. When I turn right, the steering doesn't return well in central position. The adherence is very very low and the car spinning on itself if I accelerate too much.

 

And now I ordered these parts:

 

- Pro-Line PowerStroke shocks

- Pro-Line Caliber M2 Tires (not received yet, "economy int'l shipping", grr)

- ST Racing Aluminum steering rack

- Traxxas Differential Oil 50K

 

I have to buy shock oil, I think putting 37 and 32.5 Losi. And the STRC steering rack is not a direct fit because Turnigy has updated the design and the sleeves are now molded directly in the part so I ordered the Kyosho sleeves.

 

To use oil in the diff, I'll put Loctite gasket maker.

I have a 2wd SCT

Untitled by markswebpages, on Flickr

I've only used it once so nothing much to say yet other than body is crap and has cracked already and it goes like the clappers with a 3s LiPo running a Turnigy brushless combo. It does like to take off once the air gets under it that's for sure.

Now broken, the rear gearbox assembly completely snapped off. Only it's second run ever and only running 2s LiPo. See my thread for pictures.

Ordered bits to fix it but based on it's performance so far it will be for sale on eBay and here once it's back in one piece.

Certainly not as strong as I'd hoped.

Well it looks like i owe my SCT an apology as it seems to have been user error.

I'm not really sure how this came about, but the reason it lacked strength is because these two screws where not fitted

IMG_20140428_183205 by markswebpages, on Flickr

I think that the previous owner never fitted them when he built the kit (I can see how they could be missed as the instruction aren't great) and then I look it apart to sort the gearbox and didn't notice as I didn't have two screws left over.

Either way it looks promising and I've ending up with some alloy parts on the buggy so all good.

I have ended up with a set of alloy rear hubs if anyone is interested (they will need a spacer to fit as I discovered, because I guess they're designed to be fitted with the alloy wishbones)

Little video from this week-end

 

[Markswebpages]

Bless, now mines had some proper use it's not looking so tidy.

I have enjoyed using it, now I've toughened it up a bit other than a upper suspension link pulling out of the plastic (which i fixed by putting a nut on the bottom) it's been much better than expected to be honest. Also changing tyres has made a massive difference even though it was only cheap Traxxas ones!

Next time i order something (Probably a new shell)I'll get the front hub carriers, the front suspension bottom mount and and possibly the shock mounts and that should leave me with something perfectly robust and usable for a while.

[Drnose]

So, having thrashed the shell to pieces on mine, has anyone got any hints of alternative shells? Blitz shell fit? I'd rather get something a little more robust second time round.

[Markswebpages]

Took mine out for a little bash today. Still waiting for the other pair of wheels so I front is different to rear.

The body is knackered already and the shocks all leak, the motor mounting plate now has two stripped screw holes but is still serviceable, but funds are low so any upgrades will have to wait.

Good fun and I still don't think you can beat it for value for money.
