Been looking around for some new ESC's and in not sure what to go for as im only using 2 drill motors right now on 18v. Looking to get better esc's with a view of speed 900 upgrade
Looked at botbitz, victors, sabtertooth and scorpion and know they are all tried and tested, but want to see what peoples preferences are
Botbitz 85a all the way. Very tough, amazing customer support and best value for money.
Admittedly haven't used anything else (so why am I here?) but thus far we see no reason at all to move away from Botbitz for our future endeavors.
scorpion .... best speedo i've ever used
Which model scorpion would you recommend?
XXL Ilyama version, as long you don't go over 4S Lipo, otherwise the TZ85 from BotBitz.
Scorpion XXL V2 , use one in cobalt and its brilliant on 4s
Surprised to hear the Scorpion has such a low voltage rating, never realised that.
Considering upgrading the ESCs in Bitza but we run a 6s.

And the speedo takes a tiny amount of time to reset the current limiting.
The above is why I went to Victors, much higher current limiting so I can dump as much as I need into my 900's. The Botbitz 85a may well do the trick, but I've yet to have any issues with my victors.
Im leading to either the botbitz or the scorpion I think. The sabertooth seem to unreliable from seeing experiences and the victors are quite expensive for a pair
Yeh the sabertooths are a little structurally weaker than the other controlers which lets them down, if shock mounted and covered to protect them from impacts there fine, it's just inconvenient. So I probably would avoid them as their high maintainance. I'm soon to be testing mine under harder electrical conditions, so it should really test their current limiting. Although I have little faith in what im going to do to them. We'll see
can shock mount them easy enough and a little box aint all that much work but seems you can do better now for near the same money, especially with botbitz being used more
yeah i know, the lower end control is brilliant on the sabertooths, same with some of the other more expensive ones, i just dont think the botbitz ones have any where near as much as control as the other ones
They both have their points but in most situations, especially in the larger arenas low end aint really what you use
The sabertooth has the advantage of being a duel so compact but it will need modification
I've used the BR-XL's ( http://holmeshobbies.com/product.php?pr ... featured=Y ) with a lot of success in my Feather running 18v Dewalts on a 6s Lipo. I recently switched over to a prototype RageBridge ( http://e0designs.com/products/ragebridge/ ) that is in production right now and will be released publicly next month. Both are fantastic controllers and I am happy enough with the RageBridge that I intend to use it on any upcoming hobby/featherweight bots I build.

Am I right in reading you'll need two BR-XLs?
I think cost is the biggest factor for a lot of roboteers and personally I really the braking option in the BotBitz. We're in the process of hacking our own but yet to test.
cost of rage bridge?
From his other website:
'$200 gets you the board with headers and 6€³ long power and motor wire pigtails soldered, ready to connect using servo cables to your signal source. No connectors are included'
So expensive but potentially bulletproof
My only concern with these boards is the support you get with them. Granted if something went wrong with a botbitz controller it would likely be chucked and a new one bought as they are cheap enough especially if you hacked it yourself. That was the other thing I like about the electronize controllers. I can easily fix them myself.
A $200 speedo is a bit different and how likely is that it would be fixable 4 or 5 years down the line?

And finally, the return policy is flat fee, no questions asked for exchanges stemming from failures and burnouts, except for dead-on-arrival which will be the buyer€™s responsibility to ship back for exchange or refund within n days, where n is a number to be determined.
