If it is a brushed motor (two wires going into the motor), you could run it directly off the pack with just an "all on, all off" switch. Not recommended.
A Heinzmann is the latter type. I also have a similar brushed geared motor among my collection, and it is torquey and can run on very cheap brushless controllers, or pure DC in.
Thanks for the advices Chvid. True, just on and off, probably will just make the bike twitch, but also i disagree the normal type of accelerator (revo). Rather something like a push button will be more on my liking.
I think the heinzmann is the best for what I want, I know is a bit out of fashion, heavy and noisy, But instead it has a great torque, from what I know it has metal gears. I would like it to have epicyclic train like brushless ones, but someone told me that it has actually a single gear on the main axle and a crown gear. Epicyclic give me a bit more trust in reliable..... mostly, if there are metal gears.
Brushless, look smaller, but In my view, without being an electronist, the hall sensors just give a kind of virtually data transfer between controller and hub, witch can result in power loosing or failures. Of course with the advantage of being silent and most of them with planetary system.
Do you know any photos with an opened (gears syde) Heinzmann ?
