Any feedback on the SF 300 ESCs?

Kevin I would suggest to use a big capbank....it solved all issues with my Castles.Gill

Define "big"? I use the Castle bank with 4 caps on it, do you mean bigger?

Edit: Just soldered together (6) 65v/470uf caps, tripling what the castle bank had.

Yes I ran it on my deltaforce 33 " mono , I like the speed controller so much =D

Kevin I'm using the Etti saw capbank 63V 5000uf.Gill

I had that in my cart, but then I realized I had a whole bag of 470uf's. I may pick that one up at some point though, how does it solder on by the way? It looks like it has half circles cut, do they fit over the wire so it lays down on it's side?

[grsboats]

Yes it fits over the wires.Gill

Keith, i have a 32 river cat with a castle 1515 1y. Running two max amps 4s 4000 mah parallel. Sport boating only. Bought a new castle hydra 240 but it doesnt fit where i need it too. Any ideas for 180-200 amp quality esc with a low fit profile?

[Bduncan]

Send your 200 back to castle. I just sent a 240 in without a note email or anything and they sent me a new one no questions asked

SF240HV+ with added caps went poof 2 min into the first run...........
Got an SF300HV Pro + today and put it in for a quick test with the same setup. First of all, it is frustrating to wire/rig up, wires are real short, coming out the bottom, with dual leads for pos/neg, which have to be connected in paralell externally anyhow. Pics show my quick wire solder job to get her in the boat. Soldered a #12 jumping leads together while feeding it through a ETTI 5000uf cap bank, and the whole unit just tucks in next to the rail, upside down, with wires coming out from the top.

After calibrating it and running for 3 min, data logging shows 157 amps max(very low), and under 25,000rpm, and only shows 82% throttle input, but I was pinned most of the run, it ran a modest 53.9mph on gps.......
Has anybody noticed this issue?
I always thought she had more revs left in her, even with other controllers, so next time, I am going to calibrate at 100% travel on the TX(as I always do), then try cranking it up to 125% and see if it will rev higher and record full throttle.

Again, this is a 45" Sniper on 10s2p, Castle 2028, X460/3........
I appreciate any experienced input!

You will have to increase the throttle range on some transmitters. I have my DX4S on 150%.

Thanks Rocstar. Do you mean to increase it before calibrating, or after? I appreciate the input.

I've done it both ways and hit 100% throttle on the logs each time.

Not if you use one of these.
