The Kyosho Inferno MP9e TKI4 delivers the same controllability, superior airborne posture and great agility through optimal mass concentration and lower center of gravity that makes the TKI4 nitro car superior. Updated with the MP9 TKI4 longer front suspension arms, front suspension holder, front shock stay, rear wing and wing stay allows the e-version to deliver the same handling qualities on low through to high grip surfaces to meet the needs of your specific driving style. This design update not only delivers improved performance but also improved maintenance efficiency and higher durability. Designed and built to win, the MP9e TKI4 carries on the Inferno legacy of dominance.

NOTE: Electronics, wheels, tires and body shown in photos are for illustrative purposes only and are not included. See needed to complete list below for a full list of items required to complete the model.


  • With front section and rear wing components from the MP9 TKI4, wider scope for setting options allow drivers to tune the chassis to their individual requirements.
  • Updated shock tower and upper suspension holder raises the front upper rod height by 2mm for optimal camber during chassis roll.
  • Hard coated Big Bore shocks resist external damage and feature a special low-friction surface treatment that allows the f1.55 holed pistons to move smoothly.
  • Improved handling and cornering using 2mm longer front suspension arms with extra ribs for reinforcement.
  • Aluminum knuckle arms allow optimal ackermann using an updated tie rod position that minimizes the bump steer from the long suspension stroke of 1/8 buggies.
  • Reinforced servo saver contributes to improved straight line stability and direct steering feel.
  • Two additional vertical wing fins deliver increased stability over jumps. Flaps (2 types) can be attached to increase rear grip.
  • Redesigned wing stay shape minimizes deformation or damage of the wing. Rear traction settings can be changed by adjusting the position of the wing: forward/backward, height and angle.
  • Precision 2-piece motor mount provides superior heat dissipation and allows easy adjustment of backlash or replacement of motor by loosening two screws.
  • Aluminum knuckles optimize ackermann for smoother cornering
  • Thicker ball end on the steering tie rod increases durability
  • Revised design of mounting pin for the oil shock arm allows more secure installation and improves durability
  • Revised design of the shock boot catch prevents damage to the shock boots
  • Heavy-duty universal shafts on front & rear drive shafts and center shaft
  • Dirt guards on rear suspension arm protect the drive system
  • Equipped with popular cab forward body
  • Full ball bearings
  • Compatible with a wide range of INFERNO MP9 TKI4 optional parts

Kyosho Inferno MP9e TKI4 1/8 Electric 4WD Off-Road Buggy Kit
Buggy went together really nicely. Manual isn't quite as nice as a Tekno but the parts quality is awesome. Hard to go wrong with a Kyosho.)

Kyosho Inferno MP9e TKI4 1/8 Electric 4WD Off-Road Buggy Kit
I said I'd buy this if anything else went wrong with my Tekno eb48.4 - see my review there. My buggies are losi 3,Tekno eb48.4 and this. How do they compare? In my view the MP9e is the best value for money for the following reasons:
The tolerances of the other two can be measured in tenths of an inch, MP9e in the thousandths. The wheels for example on the other two can wobble almost a whole degree when setting camber. The cause is play in both the outdrives and within the bearings themselves. The MP9e outdrives are precision machined, no anodising, perfect fit. The bearings still cause a wobble but it's much less, setting camber no sweat. This attention to detail is repeated in every other component, no compromise in quality, no shortcuts taken. Where metal is needed it's there - eg aluminium rear wheel hubs and front knuckles. More expensive than plastic but far better for durability, less bulk and lower unsprung weight. The motor mount is another example, it's more solid and cleverly engineered, no need to flip the buggy to tighten the second screw as it is with the Tekno. The MP9e also adds a plastic piece that sits at the other end of the motor between it and the chassis, this is reduce any downward pressure/flex when landing etc.
The Tekno's biggest let down: soft poorly moulded plastic. The plastic quality on the MP9e is very high and the type of plastic appears to vary depending on application, no one size fits all. The A Arms for example - the hinge pin falls through effortlessly, no reaming needed and again the tolerances are very small. The plastic strength is up there with the losi which I've found to be so far virtually indestructible. All the ball inserts fit without little friction, the others bind but more so in the losi. The upper front arms with the inner hinge pins is a more elegant answer than ball attachment. The end result of all this is suspension arms that fall freely.
The front/rear diff are smaller to reduce COG. A grub screw allows for insert of a gear pin but I also found it was a great way of bleeding the diff once tightened and reducing any potential positive pressure caused by overfilling the diff case. Kyosho please add one to the centre diff!!
The shocks, Tekno is smooth, these are smoother - no contest, the slippery coating works like a dream. The blue springs can be seen on pro driver's cars from other makes, testimony enough to their quality.
Hardened steel spur gear whereas the other do plastic. It's not too loud either.
The cnc machined items had the odd minor chip here and there and might not look as nice as the Tekno but they're better: lighter, better engineered and therefore stronger. The D block for example - beautifully engineered for structural rigidity, screwed at 4 points, yet lighter than the tekno equivalent.
Whilst the wide body makes the buggy look heavy, it's the same or maybe a fraction lighter than the Tekno. The bigger body also offers a far bigger canvas to paint. The losi is probably the better proportioned of the three.
No issue with ESC choices, plenty of room, the battery tray is surprisingly tight but still fits 2x2S though the straps could be longer.
This is my Porsche 911 Turbo. The losi is my next favourite which I'd call a Porsche Cayman. It's good but for $100 more the K Car is worth saving for. The Tekno, big following, but it's no where near in the same league as the MP9e and to a lesser degree the Losi, I think of it as a work in progress - the development mule. For $150 difference I'd save for the extra cash needed. These are all fast cars but the MP9e is another level of class, no compromise to reduce cost, years of experience and evolution. This buggy requires no further purchases, it's ready to race right out of the box.
It is a challenging build. The instructions arent great but patience and maybe You Tube for the uninitiated and I think anyone could build this buggy. I only had issues with fitting the bumper which required a little trim and the shock mounts were a little tricky with alignment. Use quality tools and apply blue thread lock on all screws going into metal. If you're on the fence as to whether the extra cash is worth it then buy this buggy. Regret costs more than $150.)

Kyosho Inferno MP9e TKI4 1/8 Electric 4WD Off-Road Buggy Kit
Got this kit 2 months ago, assembly is great, a bit tricky since the instructions is not very clear. Love this buggy ran it for the first time a couple days ago and it is very smooth, quiet, fast and handles the corners really good. Jumps very nicely. Only one disappointment for 700 dollars it be nice if wheels were included like the nitro version. I think I should have bought the nitro version since the electric conversion is only 100 dollars. At least I could easily switch back and forth unlike other brands they are mostly straight foward and unable to convert. Get a kyosho and don't look back!)
