What's This?!
Dean's Marine:
Hi nothing wrong with them, I have a good few models that still have them in and still working fine, and if you wire them up wrong the magic smoke warns you, swap wires around and it still works, try that with electronics

Colin Bishop:
If you get the right match between the motor and the board they work really well as Ron says.
I had two of then in my Isle of Wight Ferry Shanklin which were wired up with limit switches to give mixing on a 2 channel RX without the use of electronics. I still have the wiring diagram I worked out but I don't understand it anymore!

Subculture:
Give me an ESC any day.
Neil:
they were good little speed controllers in their day. i started off my rc career with these in the later 1970's.
only problem with them was if they came into contact with salt water that i used to sail on at fleetwood......they were soon kaput if they did
Colin Bishop:
Having recently battled with an obscure fault in an all singing, all dancing electronic ESC there is something to be said for simplicity. In their time Bob's Boards were a clever solution at a very reasonable cost.
Sure, today's ESCs are electronic wonders, but many of them seem to need setting up and are not always happy with the signals from certain mainstream TXs. I have had to limit the throttle throw as otherwise the ESC simply cuts out. Other defaults can give you only 50% power in reverse. You can usually get there in the end but they are often not plug and play as were earlier units. Especially when they try to identify the battery being used and apply cut off parameters if they suspect the supply voltage isn't sufficient to protect the battery. A lot of the internal programming and default setup is focused on model plane or vehicle use which is not always what we want. Boats need reverse and they don't need brakes. A recent ESC I have bought seems to be a be a nice unit but simple forward and reverse at 100% each way is not one of the foremost options.
The phrase 'too clever by half' comes to mind.
It is understandable when people who are not experienced modellers come on here scratching their heads.
