RE: Building an RC Bike from a toy
Hi Drew,
I am doing the same mods to my Nikko Kawasaki Ninja. It is basicly the same bike as yours. I have installed a Futaba receiver and Novak Speed control for proportional control. I am still running the stock motor but have a brushless motor that I hope to install soon. I am running a 11,1v Lipo battery. The 11.1v battery gave it a considerable boost in top speed and quickness.
I am experiencing the front end wobble like you did. Did taking the slop out of the top of the steering head help the wobble? I imagine it would...but if your steering head is like mine...it is actually flared at the top allowing even more slop. This leads me to think it was designed this way for a reason. Maybe allowing it to turn better or something. Please let me know if cleaning up the slop had any adverse effects.
Also I will be adding weight to the riders legs to improve high speed turning.
Thanks,
Bill
