I find it difficult to make decisions on the hardware to use for the Inside F5J.
The suggested motor and speedcontroler (Hacker A20-22L EVO & Hacker X-40 SB PRO Regler) are together a hefty €140,- (approx, pending supplier).
Also, the suggested speedcontroler is a 40 Amp one,… this seems a bit big as the max suggested current is approximately 20 Amps. Furthermore, the stuff from Hacker usually can take a lot more then the rated power.
Anyhow, our beloved Asian supplier has so many alternatives that it should be possible to pick something from their catalog… Initial search queries below…
