Nikko Dictator and Nikko F10 Rhino / Thunderbolt

[mark]

Just wanted to share some pictures of my Nikko's

Nikko Dictator I and II











Cleaned up the gear boxes and added bearings







Nikko F10 Thunderbolt and Rhino




















I converted the blue to hobby grade including 2.4 radio gear inside the original Nikko radio. I also converted the front end over from the Traxxas Cat, it bolts right on and provides a wider front track.

Some bench pics.







Grass Hopper wheels and tires on the white Nikko F10 Rhino along oil filled shocks.

I've got to admit I like the Dictator , very near a hobby grade car in a lot of ways , there's a guy on RCGROUPS who has done a double BL and 2.4g conversion to one , it looked a lot of fun !
Here's a link to the thread by Nowinaminuite on rcgroups for the double BL one [url]https://www.rcgroups.com/forums/showthread.php?2856659-Nikko-Dictator-One-pretty-One-ugly&highlight=Nikko+dictator/url]

More things about Nikko Thunderbolt

Tires for Nikko Thunderbolt / Bison / Rhino:
http://reparar-cochesrc.blogspot.com/2016/11/neumaticos-de-nikko-thunderbolt-bison.html

The rim is 50mm in diameter (1.9 "); the original tire is hard to get.




One option is to put a crawler tire with foam insert. The tire is bonded with contact adhesive.






The tire diameter is 100mm, much larger than 85mm of the original tire diameter.

Another option is to put the Tamiya Hornet rear tire. This has an internal hole of 36mm (1.5 "). If you cut with a cutter the inner edge of the tire (very careful !!), the operation of mounting it on the rim is easier:

There is also the option to change the wheel. The Nikko car wheel adapter copied from Tamiya.

The Tamiya rear wheel (Hornet, Frog) can be attached to the Nikko adapter and also, the Nikko Thunderbolt wheel fits well to the Tamiya adapter. The Traxxas (The Cat) adapter is similar but I don't know how it fits well on Nikko or Tamiya wheels.




If we want to use a wheel with a 12 mm hexagon, we have to use a long adapter that has a inner screw to fix the 5mm shaft of Nikko car.





The picture shows the adaptor fixed to the shaft and a wheel with 0mm offset.

The Nikko Thunderbolt was sold with 380 and 540 motors. The 540 motor version was a 35T or 45T motor: 12600 rpm at 7.4V and 1.3A no load current y the car has full proportional control electronics.

I have tried to put a 27T motor (Johnson "silvercan" motor of Tamiya) of 18,000 rpm and 1.6A no load current. The original electronics do not overheat.



The original electronics have a "H-bridge" of bipolar transistors: 2SA1129 (pnp) and 2SC2654 (npn). These transistors have a maximum current Ic = 7A and drive a peak of 15A.



The collector-emitter saturation voltage of these transistors is Vce-sat = 0.3V at Ic = 3A or
Vce-sat = 0.6V at Ic = 5A, so the motor is powered between 0.6 or 1.2V less than the battery voltage.

The motor speed is lower than the same car with ESC (electronic speed controller) of Mosfet transistors.

Hello friends, I am new to this site and I am from France. I have a nikko thunderbolt rc. Sorry for the language I am using a translator. I need to change the battery connection plug but I don't know where the black and red wire solder points are on the electronic board. Do you have a photo of the electronic plate or a drawing?

thank you

Is this similar to the Red Arrow?

Has anyone ever heard or seen of reproduction decals for the Nikko rhino?

Whilst clearing the loft I found this Rhino F10 which was given to me back in 1987.

Unfortunately, one of the rear dampers got broken and it was put into storage. I'd love to get it going again, I will create another thread to seek spares or alternatives.
