RE: My 1/10 unlimited oval Inferno TR15 (TR21 now)
Well, it started life as a stock Kyosho Inferno TR15. I bought the car to race in my local track's dirt oval 1/10 open class (nitro and electric, run what you brung and bring alot class). I used to race a custom creation that started life as a Kyosho MP-5, but the 1/8 scale coversions were outlawed the year before.
The kit comes with bushings, so I added full bearings during the assembly process.
Knowing the stock kyosho engine wouldn't be up for the task, it was swapped out for a Mugen MT-12 rear exhaust engine with associated pipe.
Being a nitro/electric class, races last 6 minutes. The 75cc tank would be extremely tight for time. Not wanting to go to an 1/8 scale tank, I found a 100cc one from a kyosho super10. While I was at it, I also picked up a pair of kyosho special differentials (hardened steel units replacing the stock cast ones). Completing the drive train were front univeral drive shafts.
With a larger tank and a slide carb engine, I needed to rearrange the chassis. Out went the radio box. After relocating both servos and new tank, the chassis layout was pretty much complete (the second tank was a very recent addition that has since been removed).
To compliment the chassis, I replaced the stock plastic shocks with some kyosho gold shocks (best shocks you could get in the '80s).
In this configuration, I won several A-mains and finished no worse than 2nd.
In my never-ending quest for more power and speed, out went the mugen 12 and in went a Picco Maxx 21 with RD Logics pipe. To fit the engine, I needed to cut new engine mount slots on the chassis. For an engine mount, I used an adjustable one from OFNA.
When it came to mounting the current body, I used a Jammin Jay rear graphite shock tower for an MP-6 (with slight modifications).\
Now all I have to do is find some traction.
