Kyosho ST-RR conversion

[George16]

Well, I finally was able to solder and install the Tekin truggy combo into my ST RR. I ran it for a about 15 minutes today (just straight passes on asphalt) and I was surprised at the smoothness of it. It seems to be more powerful compared to the Castle/MMM combo because I was able to ride wheelies on the the truggy when normally it would not do it with the Castle combo. I will be changing the center diff oil to about 10-15K later to prevent wheelies. The Tekin motor is 2000Kv (equivalent to Neu 1515 2D).

Here are some pictures of the install.

Soldered the wires. Tekin does not supply battery wires.

George very nice truggy. One thing I wanted to mention, I am also using a Tekin motor and if you have the motor wires soldered on out towards the back like you do the mass/momentum of the wire can pull the motor solder tabs away from the circuit board. I have rerouted my wires so they are mounted out towards the front of the motor and I have had no issues with the motor solder tabs.

Rerouted wiring over the motor vs out towards the rear.
