Hi There, I have just purchased a new Kyosho Inferno 1/8th Buggy after having had about 10 years out of the Nitro scene. I'm looking for some advice on some good engine options. I won't be racing at the moment - so trying to understand do I go for .21 / .25 / .28 / .30 How do the tech specs help me to determine if its a mental fast engine or not... should I focus on the Hp or the RPM ? Budget not too much of an issue, I just like having pretty ballistic models that are super fast (as have plenty of space to run them). Searching the forums, I see lots of motors being discussed from about 10 years ago, RB, Novarossi, WERKS, but can't find much about the quickest motors today... Also where to buy them from in the UK... ?

Thank you very much for sharing your advice, really appreciate it. I will order up the 60Amp and hopefully that makes for a more reliable set up.

I recently bought a Tamiya Hotshot re-release, and upgraded the motor to a 10.5T brushless using the 13T pinion. I have the standard Tamiya TBLE-02 ESC, with a 2S Lipo. I purchased the Tamiya ESC fan, as recommended with the brushless set up, and all installed working fine. Everything was working well for maybe x2 charges, but now I'm getting a shut down after about 5 mins, with the ESC flashing Red, which I understand is an Overload protection error. The ESC is not hot, the motor is not hot either. I tried running the car at night, with the body off, and also removed the access cover to the ESC, so plenty of cold air... but still getting the shut down and Red flashing light on the ESC. So my question is, am I really So much on the limit of the ESC (I don't actually know the amp limits - constant or peak) but it does say it will work with a 10.5T Brushless motor ? Should I just accept defeat and purchase one of the Hobbywing Quickrun 10BL60 ESC's ? Or should I purchase a Quickrun 10BL120 to be extra safe and totally covered ? Is there any downside to running a an ESC that is twice as capable as what might be required ? My thinking is that if I run a 120A ESC when I only really need a 60A ESC, then it will be almost bulletproof, thinking that if it is hardly stressed, it won't get hot, and will never get close to the amp limits so it is not working very hard and therefore unlikely to fail or shut down, but im not sure it that is the correct logic?

Looking good, just a shame that everywhere is out of spares! Been waiting on Proline Power Stoke Shocks for over 2 months! I'm through my first set of tyres, and have to order the metal braces from a hobby shop in Australia !

Hi Bert_w164, I think you may be right about the airflow under the shell - I suppose I was hoping not to cut the shell up too much, but I will make a few flow holes and see if that help. The ESC runs pretty cool, but the motor is roasting. I haven't experienced any thermal cut off, but can imagine it's doing the motor much good.

Hi there, I am running an HPI WR8 Flux on 3s with a 15T pinion (standard) but the motor seems to get very hot. I have tried a 14T pinion, but didn't change much and I have checked the drivetrain and all seems to run freely, and the spacing on the spur gear is correct. Does anyone have a good recommendation for a motor fan ? I think it would need to be a single fan, but I wondered if fans work at all, thinking that they create a cool spot on the centre of the motor can, but perhaps the other side of the motor or the ends of the motor would still be just as hot ? Any advice greatly appreciated !

I'm a bit late to the HPI WR8 party, but I got my car on Friday and had my first real outing with it today in my local shopping centre (after everyone had gone home and the place was deserted... OH MY GOD, I love this car !! It is insane !! I'm running it on 3S, with a 15T pinion and I am really impressed with it out of the box. I have some Proline Power Stroke Shocks and camber turnbuckles on order, but this thing is fantastic !

No, I was looking at Temp Guages, but wasn't sure which is a good one to go for, and trying to find a shop with stock. Mesh seems about right, small gap, no binding... Are you running 4S on the standard ESC with a 15T pinion ?

Hi There, Just getting back into RC after many years away from the scene, as I suspect lots of people have done through lockdown. I just recieved my new HPI WR8 Flux yesterday, which is completely stock at the moment, and running it with a 3S GENS Ace 5500 50C battery and it is AMAZING, crazy fast and just love the handling of the car. Ordered some Proline Power Stroke Shocks which should be coming in a few weeks I hope. Just one question, not sure if anyone has a similar experience, but it seems that the motor runs quite hot (I have only had a couple of short runs). It is running the standard 15t pinion. I have found a 14T pinion which I will try as soon as it arrives, but does anyone else have any experience with the WR8 on 3S ?
