Anyone here is still upgrading the old F10 frame buggy?

[Hibernaculum 920]

When it comes to re-selling, it should be noted - ripping these classics apart and forcing upgraded motors, electronics, suspension, etc into them, adds nothing to their re-sell value - and will probably reduce it. I've never had another collector write to me asking for a modified Bison F10. They all want original.

Hacking is fine - provided you are only doing it to keep the car for yourself. An original example in great condition (or of course a new example) will always be worth more than a hacked example. So keep that in mind if you think you might sell it later.

Some original spare parts were sold for the Bison F10 - including wheels and tyres. @WV001 have you looked on eBay? There have been some of these listed for sale, for weeks and weeks. Like all vintage parts, Nikko spares are valuable because not a huge amount of spares are left out there. Can't expect to get them for nothing, but they are available from time to time - particularly from sellers in places like Italy, where these Nikko models were very popular and even used to have TV commercials.

Hi. im new on here but thought id add a couple of pics of my old thunderbolt. Front was strenghened up as original bumper was broken. It has a 3950 kv brushless fitted and full bearings along with modified back suspension and re mounted shocks because casing was split on original mounts. goes like a rocket now cant wait t try it on a lipo sometime. Needs a bit of a clean after a bit of bashing but at least it gets used.

Hola,
estoy buscando neumáticos y llantas traseras nuevas para mi bison F10. ¿Me pueden ayudar donde puedo comprar estos?
Busqué en Internet pero no lo encontré. ¿O puedo comprar aquí otros neumáticos que también encajen?
Ya había estado en contacto con algunas tiendas en línea pero sin resultado.
Aquí hay algunas fotos de los neumáticos
Gracias de antemano por ayudarme.

Rims and complete wheels of Tamiya Hornet are compatible.

Tires for Nikko Thunderbolt / Bison / Rhino:

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.

 

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.
