Speed controllers to use with mobility scooter motors?

[typhoon_driver]

I would assume that the reason they have taken a while is that they had a rush of orders through for battlebots / robogames. Now that things have calmed down on that front build wise they will be able to catch up with the backlog.

The Vypers are showing up as in stock with Robot power, and back ordered with Robotmarket place, but there is a $50 difference in the price.

[overkill]

Robotpower had to increase the price by $49 USD at the start of the year; if the RMP honours the old $199 price (bet they won't!) you would be getting a real bargain.

I hope RMP honour their price, i've bought some from them on backorder.

Think Robot Power have them in stock, well that's what it says on their site.

Not sure what other options there are for Brushed ESCs, not had much luck buying a new worry from Ian, have tried a roboteq, but not happy with it.

Have ordered brushless ESCs too, and they are all on back order! whats going on!

Good ol vantec

Team Thorak are still running both our Heavies on these and Bosch 750's

I'm running a Vantec on the E30-400 Ampflows, if you can get hold of one then go for it

[overkill]

Which model is popular in heavies? Even the large Vantec RDFR47E has much lower ratings than the Vyper and costs three times more.

[maddox10]

Robot Power ain't that popular in Europe. The market is divided between Roboteq, Wottie and Vantec.
With Mytras and 4QD as exceptions.

The 2 machines I'm sure of that use the older Robot Power Sidewinders are Bullfrog and Gravity.

[overkill]

Is that just due to the difficulty of buying them, or do builders go with older model ESCs 'cause they see them in existing bots? I know the Sidewinders had a chequered history but at least Robotpower replaced the first batch free of charge. Here is Australia, the small Scorpion ESCs have been popular and reliable.

Another new ESC option is the RageBridge 2. If you use 4 pole Ampflow motors, you can drive one motor with a RageBridge in bridged mode. Less current handling than a Vyper but better than the Vantec RDFR47E at a much better dollar per amp.

[typhoon_driver]

I recently ran the largest vantec with T64s running at 8s (so 33.6v give or take). Vantec survived two locked up T64s, one burned out completely. Solid controllers for sure.

I'm very interested in the rage bridge due to the cost and size.

[mattsdragons]

Only reason I'm running the Vantec RDFR47E is because I have one already and know it it's a solid controller, sure I could go and source something more powerful but why spend money I don't need too

Snowlabs; I've done some serious testing of motors lately and have found some rather spicy ones (as this is a new build I am taking on id rather keep the models to myself) - however a fantastic supplier of High power DC motors in the UK (such motors used in cncs and the like) are: http://www.ellis-components.co.uk/

They usually deal with larger orders but if you have exactly in mind the spec you want they are more than helpful. They offer modern equivalents to classically used motors such as the Bosch GPA 750.

Also if you have the cash Parvalux do some spot on motors! I cant say who uses them (sworn to secrecy); but I can say is he is a friend with a world champion title bot and has used them for many years!

Also stick with the Vypers as they have plenty of beneficial extras! However they are not well tested in battle yet...
