new powerhouse for my rally car

I realized that my HPI RS4 rally car was the last ‚modern‘ R/C not being on Lipo/brushless, so I had to change this with one of the nice EZRUN/HOBBYWING brushless sets from HK. It’s a perfect fit and the speedo allows to use my Lipos finally. The included program card makes life easy with changes in throttle/brake settings between runs.
