Posts Tagged ‘Kyosho Inferno DX’ Following my previous tutorial on “How to Save A Locked RC Buggy / Plane / Heli Engine?” – here is the video of my first run – since the engine got locked up from unuse.On a side note, shame on the folks at, ToyKar SG Pte Ltd- distributors for Kyosho in Singapore. They said “your engine is locked” “your car is old and beyond repair” – well.. look… isn’t it running now? Sure as hell, they won’t be getting any business from me. Never trust your nearby hobby shop tell you if they tell you your locked engine can’t be saved or serviced. After all, the next buggy I’m getting is gonna be either the Traxxas Bandit VXL Brushless, or the Team Associated RC8. If I had to get anything Kyosho, I’d get it online. I’d suggest you do so too. Check back often, I’ll be putting up a buying guide often.


Here are some pictures as promised.. My modified HPI Savage X 4.6, and my 10-year-old Kyosho Inferno DX. I was quite inspired to give my Inferno DX a re-look after Josh Cyrul’s famous House-Jumping video by a 1/8 Scale Off-road Racing Buggy, none other than the Kyosho Inferno 7.5. History has it that Kyosho popularized the 1/8 off-road race car, as in their company debut, they wanted to avoid direct competition with Tamiya – the world’s largest R/C and model car manufacturer. Consequently, rather than targeting the entry-level hobbyist, they made race-ready cars targeted at discerning RC car fanatics and “professional” racers.

I didn’t do much modding on the Inferno.. Back then, I changed all shocks to aluminum extra-travel oil-damped shocks. I remembered feeling quite disgruntled that for the same money, the Thunder Tiger 1/8 Off Road buggy had the whole works in it… particularly, metal gears, dirt guards and adjustable big-bore shocks. Nonetheless, the immature me who knew jack about car tuning, didn’t do a proper engine break-in, and worse… I ran it in a long-grass field and over-heated and over-worked the stock Kyosho .21 engine. So, I got a nice blue-topped Thunder Tiger Pro-21BR that generates 2.12 hp! Best part… I found that it’s such a good engine that it is still in production even today! I also changed the air filter to a K & N one. It’s currently fitted with my Savage X’s old, stock exhaust. Will have to change the manifold to fit an aluminium tuned pipe I have lying around.

Old RC Meets New : Kyosho Inferno DX vs HPI Savage X 4.6 Here’s a demo of the additional step to unlocking your engine after months or years of non-use…(like in the case of my Thunder Tiger Pro 21BXR installed on my Kyosho Inferno DX). I couldn’t find any other videos on this topic.

You’ll need RC Glow Fuel. I use Trinity.

I’m Julian Wong, The Professional Bum, 26 and a month ago, the child in me urged me to get some form of a play-thing to occupy my spare time. Unfortunately, my old Kyosho Inferno DX was way out of condition, and the engine was locked up from long neglect. By which time, I had already been spending days oogling footages of RC Monster Trucks online. Part of me was slightly depressed that I’d have to part with a sum of money to get something no less than what I fancied, and the other part of me was just excited to go out and get it.. after all… back when my parents got me my Inferno DX 1/8 Scale buggy, I did have a lot of post-purchase dissonance – “why didn’t I get the Monster Truck instead?”.

It was down to the Traxxas Revo 3.3 RTR and the Hpi Savage X 4.6 RTR. Years back, I’ve already been scouting Traxxas for their great offerings – like the Nitro Stampede and the T-Maxx, and their EZ-start system. However, it was my visit to HPI’s Singapore distributor Tai Seng Toys that biased me to the War Machine. It just seemed so rugged over the Revo, or T-Maxx, which had Small-Mid Block Engines. I wanted to get one toy that would last and heard enough about the Revo and T-Maxx suspension arms and drive shafts breaking via online forums, and so the Hpi Savage was it.

P.S. If you’re asking me, “why not the Savage X 5.9?” well… I didn’t want to get something too fast or powerful that I couldn’t handle. Besides, the 4.6 was already much more endowed than other trucks in it’s class. The faster the truck, the easier it is to get mashed. Having said that, I’m having fun with mine, and don’t rule out upgrading mine to the bigger engine in future.
