    @B.RAD is back. Joined the forum around the same time as I did and also started with a Mad Bull if I'm correct. Welcome back ;).

    Thank you! You're right, been away a while but had a number of projects in the meantime. Been looking for something to scratch the build itch for a few months now and this looked just perfect!

    If it's the tble02s, I had the same issue with thermal cut out on my Mad Bull, also for seemingly no reason. I switched to a Hobbywing 1060 and it's been perfecto ever since, and runs much nicer on that ESC too 👍

    Really enjoyable read, thanks for sharing. Hope the op all went ok and you've got another project lined up already!

    Love the body colour, what is it please? Car looks great, upgraditis sure is a catching ailment! 😁

    @B.RAD 17t slows it down and keeps motor temps down a bit, but as @TurnipJFsays, it increases punch under acceleration. If you have a 3300kv i reckon something around there is a sweet spot, and a 17t pinion isn't exactly expensive in fact, the kit soft aluminium pinion is 17t. Give that a go. They don't last long term, but a couple of runs won't hurt. 

    Thanks - food for thought. Punch on acceleration is not something I want more of, so I think I'll stick with the 19t for now as that is working well. No motor temp issues at all.

    Definitely stick with 17t with truck wheels. I run my dt03 truck today at the trqck for the first time in ages and its running 4000kv on a hobbywing 10bl120 on 2s, no timing on the esc, and it was doing wheelies doen the straight. It was just a bit ridiculous. I need to sell the motor. I ran it with 3300kv on a tble02s and although the esc would occasionally thermal, it was a better fit for the chassis amd limited gearing. I am thinking of going to 17. 5/2900kv ish to be honest. 

    Interesting - I'm running 19t with no problems at all, but it is very quick. Would a 17t slow it down a bit?

    Have the same experience of the speed as quoted in my post above, although it's coping ok with the 3300kv motor and on a track I think it would be fine. We've been running on grass tracks in gardens where we don't really get the space to open them up fully. I'm not inclined to make any changes, but always keen to get feedback and learn!

    I'm running Blitzer Beetle wheels with Schumacher vee4 rear and cut stagger fronts on my Neo Fighter stadium truck conversion. It has a Hobbywing ezrun motor and ESC combo, 3300kv. It has a 19t steel pinion, running on a 5000mah 2s lipo. No issues with temp in any way, has run two battery packs back to back with no issue. Only trouble is it's too fast! Can only really use about half throttle, can't get near full throttle without a significant amount of space.

    It did have a 4000kv motor in before and again no issues with temps at all, but that was utterly ridiculous, so fast it was completely undriveable.

    Quick update - took the Stampede out for a run against a range of other cars yesterday, and it was phenomenal!! I changed the wheels and tyres to the black chrome wheels and the upgraded talon tyres and I am staggered by the difference it made. Running on wet grass, you'd think the stock tyres would be better, but they were miles apart. The new tyres came pre-glued with inserts and provided so much more grip. It really was insane how much better it went. Understeer was gone, replaced by controllable drifts and sharper turn in, with better grip on acceleration too.

    I'm so happy with the set up now, the goolRC motor and ESC combo is the perfect power for the truck, especially with the 15t pinion, incredibly quick but not ridiculous and now with the new wheels and tyres fitted the whole thing drives like it always should have. Quickly becoming my favourite runner! 😁

    swap all my cars (where I can) to a solid aluminium servo horn, as a run metal geared servos. Helps remove any play/flex in plastic ones.

    Ah ok, good tip. I was just lucky I had a suitable horn in the spares I happened to take with me. I'll run it like this for a while then upgrade to a metal horn once I have it all apart again.

    Have bought a second shorty battery now too, so max runtime is now available! Can't wait for the new tyres to arrive.

    Lots of love for the DB01 which is great to see. Sadly not available to purchase anywhere at the mo, as that would have been my go to buy without even asking! 

    I've just had a great session with the Kyosho, running a full battery pack through it with no major dramas. Found more bodges from the PO in the form of a drilled out servo arm, so the ball connector kept pulling out. Fortunately I had spares with me, so popped the appropriately sized servo arm and a fresh ball connector on, and cracked on. This buggy is so, so good. The handling is sublime. It was far quicker than any of the other cars running today, even those with faster motors, just from a pure handling perspective.

    Next on my list is some grippier rear tyres and a spare shorty battery, and we're good to go!

    Have done a strip down, found more rounded bolts, and fixed the slipper. The nut holding the spring was completely loose, so I've tightened and adjusted it. 

    Just had a run in the garden - wow! This is completely different to anything I've had before. It's so responsive, and the back of the car flicks on turn in, making it so sharp and quick to turn. It's a blast!

    Quick update - one short run, and I can tell this thing is gonna be awesome! Turn in, grip, speed, it's all there in spades. So different from anything else I have!

    I did have some problems however. First, the servo wasn't working. Had a spare so swapped that over. Second, the motor ran fast in reverse, slow in forwards. I've had to switch the motor to ESC wires around, and change the throttle switch on the tx to get it running right. Third, the motor pinion instantly fell off. The grub screw was completely rounded out. Fortunately had a spare with me so got that reinstalled. Then finally the slipper clutch gave out. I think it's just the spring adjustment, but I need to take it apart to check. Not the ideal first run! 🤦 But what time it was working shows some real promise. 

    Where I need help is the following, if anyone can help in any way, I'd be most appreciative:

    Any links to spares suppliers, specifically for a slipper clutch and other core items. Or if anyone has any bits they wouldn't mind selling please let me know.

    Would anyone have a ZX5 bodyshell available? I don't think the one supplied is for a ZX5 as it doesn't fit right. 

    Set up sheets, ideally for grass running. Or anything to give me a starting point.

    A source of the countersunk hex head bolts, lots of them are rounded out.

    Thanks in advance all, any help or advice is very much appreciated!

    As previously mentioned in this thread and the ones quoted, they are a bit hit and miss.

    Oh really? I must be lucky and got a "hit" then 😁. Have been working really well on my Mad Bull buggy conversion. 

    I guess it depends how much you want to spend and how much work you're willing to do, it's certainly a cheaper option to try.

    The Kyosho Lazer ZX5 FS2 SP (what a mouthful! Going to have to come up with a new name for it, can't go around saying that all the time!! 😆) arrived today.  As with all things eBay, it's not quite as good as it looked in the photos, but it is at least intact and nothing seems to be broken. I remain happy with the price I paid for what is a "proper" racing buggy and it came with a brushless ESC and motor combo and servo too, plus a 5000mah 2s shorty lipo too. And a whole massive bag of spares for all the critical bits, plus the original items where upgrades have been fitted. So all in not too bad for the price. I've no idea of its history, but I'd like to think it's been raced given the money that's clearly been spent on it.

    First impressions are good. What a leap from the models I've built so far! Shocks all feel good, the suspension is very smooth and the level of suspension and geometry adjustability is phenomenal, certainly way out of my league. I'm sure I'll be asking lots of questions about that soon! 

    Some photos:

    Quite a good looking thing I think. I'll be needing new wheels and tyres soon, not much life left at all, but will be good enough for grass track bashing in the garden.

    The seller made it clear in the ad that he had taken a Dremel to the chassis to make space for a shorty lipo (included) and that all that remained to do was drill a hole for the supplied battery post and fit a strap of your choosing. I actually hadn't noticed that bit of the ad when making the purchase 🤦 but no bother, the bits were there and I have some handy bits of perspex leftover from making timing struts for sprint cars.  Photo above shows the chassis modification, which is pretty neatly done, and the pen mark where I laid the battery in and put the post where it needs to go.

    Drilled the hole and made use of a countersunk bit...

    Measured and cut out a strap from perspex and drilled the holes out to suit the machined recess in the post nuts. Et voila!

    First bit of personalisation/modification complete.

    I have also now installed a receiver, although the only one I had spare is the Carson stick transmitter set that came with the Mad Bull, which isn't a terrible thing, but it's not the most ergonomic of stick transmitters. I velcro'd the receiver in place so can easily change this if I decide to upgrade the transmitter. 

    Final step before a maiden test run is to charge the battery. The shorty lipo supplied is a different type of battery than any I have (Tamiya, Traxxas and deans) - it just has these 4mm post holes in. Unfortunately this means I have no way of charging it. I did a quick Google and see that the battery should actually come with a double ended charge cable to enable charging, but this wasn't supplied by the seller. All credit to the seller here though, as a message on eBay was instantly responded to with an offer to send out a cable in the post immediately. Hooray!

    Hope it arrives soon as I'm itching to drive this thing! 😁

    Kyosho Lazer - simple plain vanilla modern buggy

    I've just won an eBay auction on a Kyosho Lazer ZX5 FS2 SP. Simple is good with me! It was a good price and comes with all electrics inc motor etc and a load of spares. I'm very excited to try it and compare to my current fleet! May have to take a trip to a pump track now ☺️

    I'll take some photos when it arrives and will do a bit of a strip down to check everything and report back 👍
