Is small size Lipo pack capable of powering 1:10 truck/truggy? This video shows a Dual Hunter (stock 540 silver can motor) with a very small 2000mah 25C Lipo pack. Not bad at all. However, problem will arise when you are using a more power hungry motor. We have to face the truth that smaller size […]

Dog bone shaft replacement
My Kyosho Optima has its front left dog bone missing in the wood. I don’t have any spare part for it. However, I do have a slightly shorter shaft (about 1cm shorter) from another car. I also have some extra shim washers and slightly longer shaft cups. Because the replacement shaft is shorter, I need […]
KV rating versus Turns
Technically there is NO precise conversion between Turns and KV. KV indicates no load performance while Turns describes the “structure” or “construction” of the motor. Seems like Turns is still the most tried and proven system of performance measurement even though KV rating can still be used for determining what motors are in an approximate […]
A stupid mistake….
The photos show an Optima with an onroad configuration and then an offroad one. The only difference is the tires being installed. As you can see, the onroad tires are smaller than the offroad spike tires. Smaller tires are always easier for the entire drive system. The car runs fine onroad. However, the motor fails […]
Can a Tamiya really jump?
It depends. The age of the car does matter (it is plastic afterall). This short vid shows a Tamiya Blazing Star doing slow jumps: This short vid shows a dual hunter jumping through tree roots: A Tamiya buggy cannot jump like that. The jump has to be gentle. And how about climbing through a […]
Reconnecting the charge leads
It is not uncommon for the charge lead connector to get damaged (or completely gone) when running on the track. Keep in mind it can become dangerous if the broken wires get in touch with one another! You must stop using the battery immediately, and use tape to separate them so to get them isolated […]
Is TT-02 a vintage?
I am not sure if TT02 should be considered as vintage. It is a very cool chassis though.
3d print C hub
I got a broken M03 front C hub. 3d printing has come to the rescue. I started with a 20% fill and it works great. Of course there are some sanding, filing and drilling that have to be done before the printout can actually fit in. Does it really hold up? It depends! See the […]
