Castle creation and dynamite motor amp questions

[keesey]

So I am building a 1/10 scale hydro and class requires it to run a dynamite a3650 motor at 2000kv. Now dynamite says to use a 120amp esc recommended.

Now I have a castle creations hydra xlx2 and it says to use 150amp rated connectors at a minimum.

The question I have is my batteries are all spectrum g2 so as far as smart connectors I am limited to ic3/ic5

Will I be ok running the ic5 being the motor is saying 120amp?

That ESC is way overkill for your setup. That's mot always a bad thing, but in this case, it will take up more room, add more weight, and remove more money from the wallet. The Hydra x8s would be a good match with plenty of headroom.

On to your original question, IC5 connectors. They certainly aren't the best option, but I've run them in similar setups near the ragged edge without too much trouble. They'll get warm for sure.

What I was thinking about the size, I was originally looking to run the spectrum firma 160amp esc, as I have everything else by them. Was talked out of it and into the xlx2

The best connectors are SMC's SH8's. Second to that are just plain 8mm bullets, QS8, EC8. 8mm is your minimum. I just use 8mm bullets from amazon on everything cause its cheap and universal and handle enough not to desolder themselves.

also a flycolor/OSE raider is plenty of ESC for that system and will handle over 175A. But the Castle is obviously better. To be competitive racing you will be pulling around 180-200A.

issue is all my batteries are 4s spectrum g2 and limits me to ic3 and ic5 with these boats so just looking to clear up the hydra requiring 150amp min connectors

You can put connectors rated for 5A on a Castle ESC... doesn't matter, as long as you understand it's going to be the weak link in the chain. If you're dead set on the G2 batteries and their proprietary charger, then IC5 is your limit, regardless of the ESC you choose. Those batteries are nothing special to begin with in terms of performance, just very convenient when it comes to preset charger settings for beginners. Choosing a quality ESC now will save you money in the long run if/when you decide to bail on the G2 battery system and go with a better performing Lipo supplier, which in turn allows you to run a higher current rated connector like an 8mm anti-spark.

yeah these two boats are dead set the way they are based on class requirements, have to run a dynamite a3650 at 2000kv, no more the 4s with a total capacity of 10000mah on board, so I don't think these two boats will need to go the extra route for higher amps, if anything i feel i should drop down esc size for the class but will see how these run. batteries where a fair price for 4s 3600mah at 120c soft case, and the charger makes life so simple. will be a pair in parallel on board.

HDV Whiplash Hydro
This is my Pearl running a raider 150 with a modified cooling plate (waiting for a castle x8s sale) and a Spektrum 3660 2400kv. IC5's were warm after 4 laps. You should be fine with a 2000kv as long as your prop isn't too big. But 8mm like Fweasel said or QS8s if you plan on racing and not desoldering connectors.

If anything I will drop down in esc size. Being limited to those parameters and the recommended esc size being 120amp if I switch to say the 160 firma would drop weight and no worries about ic5 as it?s rated for them.

And these are racing boats. Just a 1/10 scale limited class. Everyone has to run that motor and everyone is capped to 4s.

cut the connectors off and solder 8mm bullets on. get a ISDT or HOTA charger and made your own charge leads for it.

Everything is literally brand new, not selling of a new 200w charger and 8 batteries to change it up, would much rather change the esc, not sure how it?s being made to be this complicated.

No one?s given me any calculated reason why I can?t use ic5, being rated at 120amp and my motor being 120amp max. Heck even the firma 160amp esc comes with ic5 connectors???

If I go for peak output from the castle yeah sure I would need to change it, but using this smaller motor the draw isnt going to be anywhere near peak on that esc

If I use basic A=w/v this motor is 680w and I am running 14.8v and end up with 45.94amps sure startup could be potentially higher. And depends on prop, but that?s a fair ways away from 300amp

I told you a few posts ago racing usually pulls close to 200 amps. Then I explained you cut the leads off and put larger ones on. No selling of anything.


either way you are going to find out when you desolder the connectors and melt them.

The motor comes with 5.5mm bullets rated up to 150amp. So why would they sell it this way if the motor is just going to melt the connections off the stock motor?

So still not seeing any math and or calculations to back up anything your claiming. Give me some facts not opinions, let?s see your work on those numbers?..
