Speed controllers

I've decided to actually finally finish off my fleet and to do that I need to fit ESC's to all of them. I currently have Viper units fitted to a couple of the boats which are good but would work out incredibly expensive for the other 8 or 9 so...

Question.
Has anyone used or tried to use this kind of thing?

Are they any use or should I avoid like the plague and bite the bullet and save up?

Vigo - I doubt they will handle 320 amps for more than a millisecond , but for 10 - 20 amps I think they are OK. They are probably copies of Hobbywing's Quicrun which I have used. 

If you only need 5 - 10 amps, then these are OK. I've used lots in my smaller models - up to 385 motor

There are various versions claiming from 10 to 30 amps (which I doubt) but for low amps they are fine. There are several versions with and without brake, which is usually switchable, and from UK and Chinese suppliers.

Like Vipers, they have a BEC, and I have found that the switch actually isolates the battery, saving another switch - although do check as there are many versions .

Hi One & All

I think I have one or two in my spares box, as has been said don't be fooled by the 320 amps, the one thing that I do not like about them is that it has a break point, so you can not go from forward straight to revers in one movement.

You are right about the 'Chinese amps' - don't trust them to go very high, especially in a boat environment where there is not much cooling. They probably specify the highest possible peak Amperage based on components with maximum cooling. But a number of them have jumpers to select car (reverse gives dynamic braking) or boat (reverse gives immediate reverse).
